Long-term loans with bad credit tolerance offer an exclusive experience for people seeking for rapid money relief lasting longer. Unlike similar loan offers issued by banks, long-term loans for bad credit customers differ in deadline period, interest percentage and fees.

4 Great facts that make long-term loans useful

When a person has a poor credit history, there is no way banks will agree to issue him or her a loan for relatively substantial term. This is the case when long-dated credits come into play. Here are the reasons why those became popular among people seeking for extra cash for an extended period.

Bad credit loans:

  • require a small package of documents with no guarantor and no credit check;
  • reward a borrower with up to $2000 (some go for 20K, depends on the state);
  • give you the term of 2 years in order to return the borrowed sum (depends on state regulations);
  • can be repaid in regular installment lumps scheduled beforehand;
  • can be requested and automatically proceeded online.

Apply for long-term loans

Applying for a long-term loan does not differ from other borrowing procedures you might or might not had a chance to experience beforehand.

A borrower can receive the requested money via direct funding on his or her bank account and use them the way he or she wants in just a few steps.

  • Step 1. Choose the most suitable offer relying on current circumstances and your previous experience (if you have any);
  • Step 2. Make sure you have the requested documents available;
  • Step 3. Either contact in person by reaching the nearest point available or complete an online application form. Both options have their pros and cons.
  • Step 4. Fill out the requested information and forward the application for approval;
  • Step 5. Receive a confirmation letter in a few minutes;
  • Step 6. Confirm your interest in a loan and receive the money.

The secret of direct lenders

Probably, you already know the difference between brokers and direct lenders. As for direct lending service, it is characterized by verification and approval proceeded by the lender. No middleman, no third party representatives are needed for this form of lending. It results in a direct business deal between a lender and a borrower. Direct lending supposes that:

  • a borrower can be confident in the lender to the extent of borrower’s researching scopes;
  • a borrower can easily track personal information flow in case it’s transferred somewhere or to someone;
  • a borrower saves on extra fees paid to the middleman because there are none;
  • a borrower is free to contact direct lender for support 24/7 with no additional parties involved.

Requirements for bad credit loans

When applying for long-term loans, one should meet some basic and more than reasonable requirements:

Identification

A borrower must have a valid ID document to confirm the identity;

Income

A borrower must be employed for no less than 3 months. It proves borrower’s ability to return the money back relying on the steady income;

Location and age

A borrower must be a legal citizen of the USA and turn at least 18 years old when signing up for a loan.

Long-term loans require a borrower to be attentive to the conditions of the loaning agreement. As far as the sums for borrowing, they can reach $2000 (some go for 20K, depends on the state) and be issued for as long as 2 years (depends on state regulations). Good knowledge of every term secures a person from getting into a debt or other unfavorable or undesirable results.

No teletrack payday loans are possible with the modern technologies that boost our scopes to the utmost level. Nowadays, a borrower can sign up for a payday loan without spending hours standing in a line and waiting for a probable approval.

No more waiting hours on the phone trying to explain what you really need. Thanks to the online application system, you can send a request in just 15 minutes and save your nerve cells. Short-term loans with simplified sing-up procedures can provide a borrower with extra money in an easy and fast way.

The secret

These loans give a borrower the option to leave aside the dragging out processes of applying personally or via phone. In fact, no verification through the teletrack service implies no deep investigations on the past loans with enduring obligations or negative results one might have had or still have.

No teletrack payday loans are interconnected with no faxing payday loans. No faxing means a borrower is allowed not to send personal documents or additional information about credit history via fax. Thus, this credit service promotes utility and higher acceptance.

Things to know

Payday loan is considered an emergency solution that allows a client to improve only current money problems in short or extreme notice. Here are some basic rules one should know.

Learn the rules

  • this credit needs NO additional confirmation via phone or fax;
  • this credit can provide a person with a sum up to $1000;
  • this credit can load borrower’s account with the sum requested within the next couple of hours; in fact, direct lenders provide money transfers for payday loans within one business day;
  • this credit doesn’t ask for additional documents;

Availability

  1. Short-term loans are at your service 24/7. It is impossible to predict when a money problem will strike you in a back, and having a “plan B” has never been a bad idea.
  2. Direct lender can solve your money problem fast via direct funding in less than 24 hours after the initial request.
  3. Thanks to the opportunity to get a loan online, payday loans with no teletrack verification and no credit check are one the best solutions for the borrowers with bad financial reputation and low score.

It’s handy

When a borrower signs up for a payday loan online, he or she doesn’t confirm the identity or credit history via phone or personal contact. The procedure takes simple steps with no additional interaction.

  1. get a secure Internet connection;
  2. fill out a simple online application (request a sum);
  3. input basic information (name, address);
  4. enter the valid e-mail for feedback contact.

Comfort zone

The principle of payday loan usage is based on preserving the comfort of every borrower with zero-expenses and maximum mutual benefits. In fact, higher tolerance for past payday transactions and the scopes for online application implemented straightly from home downsize the rates of each deal and make them affordable in every respect.

Tricky

When a borrower requests for a loan, it is vital to pay extreme attention to the details. The concept of receiving a loan on such a short notice allows more scopes, still, with higher interest percentage due for security measures.

Usually short-term loans are issued for a month with reasonable and fair rates and terms. Excessive prolongations can drag a borrower into a serious financial trap. Payday loans with no teletrack and no credit check must be treated as one-time loans and used as temporary solutions for financial issues.

Instant cash advance allows a borrower to receive money fast. Easy applying procedure and fast response from the loaning service make this option very popular among people who find themselves in the situation when getting money fast is essential for their everyday needs.

Requirements for instant cash advance

When singing up for a loan, a borrower has to meet some simple but logical requirements. In the terms of complexity, they are very modest. Almost 90% of all potential borrowers meet them even before the application. In case a borrower does want to get the money fast, here’s what he or she has to do:

  • confirm identity using either legal state issued ID card or driver’s license (both will work well);
  • provide legal Social Security number (SSN);
  • confirm that a borrower is a legal citizen of the USA;
  • confirm that a borrower is no less than 18 years old.

Applying for an instant cash advance

There are a couple of ways a potential borrower can use to apply for a cash advance:

  • a borrower can drive to the nearest loaning establishment and apply in person;
  • a borrower can dial a number and apply for cash advance via phone (mobile or landline);
  • a borrower can use the Internet to apply online.

By all means, a borrower should choose one that suits him or her. Nevertheless, in the terms of quick response and comfort, applying for a cash advance online is the best way to get it instantly.

Applying for a cash advance online

In order to send your application for instant cash advance, these are some basic steps one should follow:

  1. Step 1. Research the loaning establishment for good client feedback history;
  2. Step 2. Read the requirements and make sure you meet them all;
  3. Step 3. Choose “apply now” and complete a simple application;
  4. Step 4. Wait for an approval that will take just a few minutes;
  5. Step 5. Check the balance on your bank account you entered during the application;
  6. Step 6. Enjoy your spending.

Additional Information

As far as cash advance is said to be a rapid solution for money issues, it won’t allow a borrower to request a sum bigger than $1000. Instant loans require no credit check, but in rare cases some additional information about your personality might be requested:

  • lender has to be sure that your checking account has been valid for 2 months at least ;
  • lender has to be sure that you will be able to pay the borrowed sum back. That is why it is necessary to confirm your employment and prove you have no less than 6 months of working experience at the same place;
  • lender has to be sure that you receive salary on a monthly basis, so any income activity should solve the problem.

Cash advance with no fee charges

In order to make potential borrowers interested in further cooperation, lender may offer an advance with no extra fees for the first deal. In other words, when applying for a sum no higher than $200, a borrower will have to pay the interest only. In the terms of real numbers, one can save $15 dollars on $100 or up to $30 on $200.

Time regulations

A borrower is allowed to request a small-dollar loan for no more than 31 days. If the deadline is missed, additional fees and interest may be applied.

This problem can be solved by reapplying for a cash advance but usually it brings more harm to the borrower by forcing him or her to pay extremely high fees. In order not to let this happen, the best way is to plan the expenses properly and return the money before the due day passes.

Guaranteed payday loans offer more because this form of crediting eliminates the insecurity a borrower may have due to past negative experience or unfavorable prospects of bad credit reputation. In fact, payday loans as a rapid solution for any money issue one encounters usually promote high acceptance for a reason.

Safe loans are available

Guaranteed payday loans stand out from the variety of other loan offers thanks to their availability. The process of applying for one is more than just easy. Spending a couple of minutes in front of a computer can actually turn into a decent deal on beneficial terms.

Availability and affordability are promoted by:

  • tolerance to bad credit history (usually, no credit check principle works);
  • fast online ordering service (complete process takes not more than 24 hours);
  • flexible obligations (adjustable terms).

Guaranteed payday loans don’t care about bad credit history

Bad credit history is an unpleasant point that can happen with everyone. For some reason, the very same moment a person is checked, every bank tends to close the doors in front of bad credit score carriers. This is the moment when payday loans come into play.

They always solve your problems fast and do not care about your economic background.

How to receive a small-dollar loan

Applying for payday loans online is easy, probably, even easier than one can imagine. In order to complete the procedure, a borrower must prepare a set of available information.

Requirements:

  1. Legit USA documents that prove identity (usually, these are passports, driving license and Social Security cards);
  2. Proof of being a citizen of the USA no younger than 18 years old. Payday loans are guaranteed with no maximum age limits; so no matter what age a person is, even 101 years old, short-term borrowing is still a possible option.
  3. Enough time (5-15 minutes) for careful fill-out process and secure Internet service provider for no failures on the go.

Specialties

Guaranteed payday loans have a number of features no credit loan can boast of. It makes them very tempting, while making you a potential borrower.

Specialty 1. Low interest percentage.

A borrower isn’t forced or extorted to return a fortune for borrowing a couple of hundreds; usually each $100 will cost you about $10-$15.

Specialty 2. No late fee charges.

When a borrower is late and can’t return the money on time, he or she won’t be forced to pay fees for the extra-time required. Usually, a lender offers about a week of no-charging policy as long as a customer proves reliability and commitment.

Get the money fast.

It means that the requested money will appear on your account in a few hours (within 1 business day as a maximum period). Direct funding and online application speed up the process immensely.

Be aware

Guaranteed payday loans have relatively low interest. Still, it might be a good idea to return the borrowed sum the fastest possible way. The faster one returns the money, the easier it comes on the wallet.

In case it’s impossible, keeping the required sum longer than a deadline date is not a catastrophic situation. The fees won’t become

Use Payday Loans

Have you ever had an urgent requirement of funds to meet your daily obligations? If the answer to this question is a resounding “yes“, then a payday loan would be the next best alternative to meet your short-term needs.

This is one of the best alternatives to get immediate funding for such unexpected expenses like medical bills, repairs or travelling. These credits are easy to apply for and require extremely minimal documentation.

Short-term loans are becoming increasingly popular in the US with the industry revenue growing up to nearly $11 billion.

General

  1. Small dollar option ($1000 and less);
  2. Short-term option (max 1 month term);
  3. Bad credit and no credit score tolerance;
  4. Instant approval (within 1 hour);
  5. Direct funding (within 1 business day after approval).

Your Reasons

There are many reasons that make an individual require funds on short-term basis. As a result, you choose a quick loan as a source of small-dollar financing. Some of the most common reasons that an individual opts for quick payday loans are the mentioned below.

Cover Daily Expenditures

According to a recent study, nearly 69% of people who borrow payday loans do so to pay off daily recurring expenditures such as utility bills, rent, mortgages, food etc.

As a matter of fact, it helps you cover the deficit between available funds and funds required to pay off the necessities within 1-week-1-month terms.

Pay for Unexpected Emergencies

Another 16% of people, who borrow from direct funding lenders, do so because of the urgent cash requirement to meet unexpected contingencies (up to $1000).

These emergencies can appear in the form of medical bills, car repairs, urgent travel arrangements or in grief cases with the close ones.

Inability to Secure a Bank Loan Due to Bad Credit Reputation

Some other common reasons why people choose quick borrowing is the inability to secure a bank loan because of a poor credit history. Since payday loans go with no credit checks, the service becomes relatively easy to secure a loan and hence meets all short-term funding needs.

Benefits of Quick Payday Loans

Instant Approval

Generally, a small loan requires a very limited approval process and involves very few formalities. All that you are required to do while applying for an online quick loan is to fill out a form and sign an agreement.

If the request is approved (usually within 1 hour), the entire amount is deposited to your bank account within 24 hours. The speed of the approval makes it more preferable than conventional loans.

Direct Funding

Direct lenders of payday loans provide their services via direct funding using automatic transfer systems. It eliminates the need for third party intermediaries or additional services such as collateral verifications, involvement of any guarantors or co-signers. Thereby the cost of borrowing reduces to the minimum, while the speed of the transaction improves to the utmost level.

Quick Loans Online

Unlike conventional procedures, most payday loans can be applied for through the Internet. You simply have to provide the necessary information in the blanks of the form, and the loan amount gets credited to your account after approval. This principle greatly improves the accessibility.

Payday Loan with No Credit Check:

One more benefit of payday loan service is that it doesn’t perform any credit check before approvals. It makes quick loans an extremely effective option for the people with a bad credit history or for the people with difficulties in getting approvals from banks. Our loans, in some cases, are also used to pay off other debts or to stave off collection agencies.

Easy Repayment and Refinancing Terms:

Quick payday loans offer easy terms of repayment that can be customized to suit your personal needs. They also have a relatively easy-to-understand finance cost structure, which enables you to know exactly how much you are required to repay.

Moreover, in case you are unable to pay the dues on time, there’s an option of Extended Period Plan (EPP). It enables you to pay back your amount over an extended period without any additional charges.

Typical view of a windpower plant

Typical view of a HAWT based wind power plant

Wind power basics:

How do you calculate the Energy stored in the wind?:

Wind kinetic Energy is KEw = AirMass*WindSpeed^2/2

AirMass is defined by the AirVolume that flows through the wind turbine * AirDensity

AirVolume is defined by the TurbineArea*WindSpeed & AirDensity is roughly 1.3 kg/m3

TotalEnergy KEw= TurbineArea * WindSpeed^3 * AirDensity / 2

Wind Speed is completely dominating the available wind energy. How high is it then?

Average Wind Speed

Image show average annual wind speed in Stockholm, Sweden.

See: http://www.windfinder.com/

In Stockholm then we can assume the Average Wind speed to be 8 kts or 4 m/s

Average Wind Speed in Stockholm

Average Wind Speed in Stockholm

 

Which are the factors reducing the available average Wind Speed?

Altitude Dependent Wind Speed Reduction

The image show how the wind speed is changing with altitude and type of surrounding.

As an example the wind speed on a roof top is reduced by 30% compared to high level undisturbed wind.

Wind Speed VS Different Altitudes

Wind Speed VS Different Altitudes

Wind speed Reduction and Amplification Around Different Barriers

The physical placement of a Wind turbine is greatly affected by its surroundings.

Either the wind speed is reduced by trees or buildings or it can be amplified by different objects.

AirFlow Around Different Barriers

AirFlow Around Different Barriers

How much is lost when harvesting the energy in the Wind turbine?

Wind Turbine Peak Efficiency

Maximum theoretical Wind turbine efficiency is 59%

Efficiency for different solutions is displayed in the Image.

Efficiency of Various Wind Power Technologies

Efficiency of Various Wind Power Technologies

Stuart Wind turbine - Multiblade HAWT (Horizontal Axis Wind turbine)

The dominant solution today is the HAWT with 2 ,3 or 4 blades.

+ So far the highest peak efficiency of about 47 %

+ Mature established technology with high competition

– Requires a lot of free space, sensitive to turbulence & has lifetime issues

– Not for households due to its estetic nature and the propeller generated infra sound noise levels of 30-40 db

Cost/w Small scale: 600 W for 3000 $ = 5 $/W

Cost/W large scale 45 kW for 80000$ = 1.8 $/W or 0.04 $/kWh

Average efficiency: 1kW equals roughly 2000 kWh/year

Technology Potential: Wind farms will be dominated by the HAWT for a long time with a cost/kWh soon at competitive levels if lifetime can be extended but it will not be a hit for households.

 

2. Rural windmill

rural Windmill

rural Windmill

A rural windmill like in old western movies providing water.

Multiple concave wing forces a slow rotation ideally suited for water pumps and other slow rotation applications.

+ Very low cost and simple production

+ Operates at low wind speeds.

– Low efficiency < 20%

– Not ideal for electricity production due to its low TSR

Technology potential: This is a low cost solution and may be a hit for low cost niche applications.

 

3. Darrieus Wind Turbine

Darrieus Wind Turbine

Darrieus Wind Turbine

Lift-Type Vertical Axis Wind Turbine

Instead of collecting the wind in cups dragging the turbine around, lift forces generated by the wind hit aerofoils to create rotation.

+ High Tip Speed Ratio, meaning fast rotation compared to wind speed makes it suitable for electricity generators

+ Simple construction and low forces on bearings

+ As high theoretic efficiency as the HAWT Propeller of 40 -45 %

– – Needs a push to start & breaks in a storm

Technology Potential: Very high potential due to its simplicity and high efficiency. However this may be a future solution for a long time due to practical issues connected to the start and high speed issues.

4. Giromill or H-Bar Wind Turbine

Giromill Wind Turbine on a Roof

Giromill Wind Turbine on a Roof

The Darrieus Variant with 2 or more vertical straight blades

Lift force generated rotation commonly on a vertical shaft

+ Decent theoretical efficiency 30-35%

+ Quite simple & low cost to build + Works well in high turbulence

– High forces on the structure

– Needs a push to start

Technology potential: This is already a big hit due to high performance/cost ratio however there is variant called the CycloTurbine that can twist the blades so that it can start in low wind which could be even better.

5. Savonius Wind Turbine

Savonius 3 Blade Wind Turbine

A drag type Vertical Axis Wind Turbine that uses the air to push the rotation.

Since it uses Drag the TSR, Tip Speed Ratio, is low < 1 but it works at low wind speeds and gives smooth rotation.

+ Works at low speeds and gives a smooth rotation even in storms

+ Very simple, robust and low cost construction

– Low TSR make it not ideal for electricity production.

– Low Efficiency at roughly 15 %

Cost Example: 36W @ 10 m/s @ 0.3 m2 for 500 $

Technology Potential: This technology has all the rights except for Low efficiency. New generators can probably handle the low TSR. This solution will be found in many future products.

6. Mag-Wind Vertical Axis Wind Turbine

Mag-Wind Wind Turbine

Mag-Wind Wind Turbine

An interesting combination of technologies with the aim of beeing discrete, self started, low cost and robust.

– Efficiency as a savonius engine of 15-20%

+ Discrete, robust, Low Cost & Self Started

+ Perfect for a roof top at urban homes to provide necessary household electric consumption.

See:http://www.enviro-energies.com/

Cost: 5 kW -> 12,5 k kWh/year for 25 k$

Technology potential: Huge! It is not as efficient as a Stuart mill but it could work in our homes where its price/performance is to its advantage.

New Creative Designs with Potential

7. FloDesign Jet engine Wind turbine

FloDesign Jet Wind Turbine

FloDesign Jet Wind Turbine

Jet engine technology based Wind turbine design.

See Video: http://www.youtube.com/watch?v=RagPPrHUMTY

Technology Potential: I guess if it is true what they say, the efficiency can be very high but there must be a cost and complexity issue.

8. WindSpire Wind Turbine

Windspire Wind Turbine

Windspire Wind Turbine

The Windspire is really nothing more than a slicker form of the older gyromill technology. Lift forced created rotation with 3 blades.

+ It is slicker and nicer looking which gives it an advantage of the classic Straight blade Gyromill.

+ Decent performance, COP of 30-30%

– It could be fragile even though the selling company says that it is not.

Cost: 5000$ for a system that produces 2000 kWh annually.

Technology potential: Same as the gyromill although the selling company has made a nice work productifying it for your back yard.

See: http://www.mariahpower.com/windspire-overview.aspx

9. WindPod Wind Turbine

WindPod Wind Turbine

WindPod Wind Turbine

The Australian inventor Graeme Attey has made himself quite a name in green business with this invention. It is a Savonius-gyromill combination that uses both lift and drag. It is shaped like a big tube 1 m long and 45 cm in diameter.

+ Could be on everybody’s roof tops in 10 years.

+ Very Low price/performance

+ Decent Efficiency of 30-35 percent and it self started.

– Has an optimal angle of the wind

Technology Potential: Of Course the potential is very high since it is slick, low cost and high efficient. All the rights except for the wind angle efficiency.

See Video:http://www.youtube.com/watch?v=WZ5kX5Yw4eY

10. Helix Wind Turbine

Helix Wind turbine

Helix Wind turbine

A Creative, savonius based, vertical axis wind turbine with a frame at the top and the bottom for a more rigid construction and elegantly designed.

+ Probably high endurance and quite nice to look at.

+ Low noise

– Efficiency. Produces 3500 kWh per year. Price 14500$

Technology potential: HelixWind corporation has understood the need for a slick design when going into urban locations. The design may be more important than efficiency for the targetet customers. It is however way to expensive for that output. Return on investment is 30 years.

11. HAWT made by wood

Timber Tower Wooden HAWT Wind Turbine

Timber Tower Wooden HAWT Wind Turbine

Optimization of the core Wind technologies will see many creative solutions. Making the HAWT in Wood is one of them and it is really interesting. The steel solutions up until today take damage in salty offshore conditions, the price for a wooden constuction is much lower and the complete life cycle environmental impact is greatly improved with this construction. The Tower comes in different shapes and can raise 200 meters above ground.

+ environmental friendly

+ Fast mounting

+ Wheather endurance

+ Low Cost/Performance

– Have not found any real minuses even though they need to prove lifetime (20 years garanteed).

Technology potential: If their lamination works out so that the life time is as great as they say this will most likely be a big hit on the market and we can send gratulations to the german company Timber Tower for having a bright future.

Authors Thoughts:

If a technology will make it to the big masses it has to fulfill the requirement that the business case it provides to the customers need to be excellent. Very few will invest in a green technology if the return on investment is too far off or if the sacrifice to normal standards is too high. There is also always a threshold to adapt new concepts which makes the financial aspect even more important.

As an example In Sweden the Air to Air inverter heat pumps has become very popular to provide low cost heat. Why? Because in many households the return on investment is less than 2 years.

In Sweden also the pumps from geothermal heating has become popular although they are very expensive. Why? Because at the same time it gives you cheap and nice energy it increases the market value of your home.

I believe that harvesting Energy from the wind is VERY competitive and in 50 years this market will be huge. There will be room for both large scale plants to small building solutions. There is soo! many yet undiscovered business cases to be made in the wind power industry. Price/performance is everything and new innovations must focus on lower cost and improved average wind speed solutions to make nice green low cost kWh.

This post will be continuously updated with the summary of the most relevant and promising wind power technologies.

Solar Thermal Technologies

What dominating technology will play the largest part in the solution of providing clean energy in the future?

Well the answer is that it stands between a handful of technologies where large scale or utility scale solar thermal generated electricity might be the winner.

A more detailed update of the companies active in the utility scale solar power area is found here

There are many estimations made that say that solar power generated electricity will see a tight competition between photovoltaics and solar thermal where the arguments for photovoltaics usually are:

  • Faster getting down in cost due to faster volume ramp including China and improved production techniques
  • Concentrated Photovoltaics is moving fast to lower the amount of neccesary silicon and thereby cost.
  • All PV technologies are pushing performance, Silicon PV, Thin Film CIGS, CdTe, CIS and AmSi are quickly improving their performance.
  • More modular and the infrastructure supports using photovoltaics from the best sub contractor.
  • Easier to install and lower maintenance cost

The arguments for solar thermal is usually:

  • Higher quality of the produced electricity (Less abrupt spikes from clouds blocking the sun)
  • Some of the technologies can store thermal energy to be used when the sun is blocked. Lots of research here to lower cost of the storage solution.
  • Ability to capture a larger part of the solar light spectrum like infra red, enables higher efficiency.
  • The high temperatures that are used to produce steam for the Concentrated solar power turbines can be achieved with a secondary plant based on natural gas or other biofuels and can be used during night and in the winter as backup.

I guess we will see in 50 years but the large scale solar thermal market is expected to grow roughly by a factor of 40 between 2009 and 2014 and that is not bad.

Here are 5 different Solar Thermal Electricity generating technologies:

1. Solar Tower with updraft wind Turbine

Solar Thermal - Updraft Wind Turbine

Solar Thermal – Updraft Wind Turbine

Solar Tower functionality description

Solar Tower functionality description

Principle of operation:
Heated air is generated below the glass shield covering the ground. The heated Air travels, by convection, up through the large chimney where wind turbines generates the electricity.

Technology strenghts:
+ Low cost to cover the ground with glass.
+ The moving media (ie the upward air) is moving through a limited area where turbines can work in a very efficient way.

Technology threats:
– Requires a very tall chimney
– How do you maintain a turbine within this tower??

Technology Potential:
Probably very robust way of large scale solar thermal generated electricity where these types of towers are allowed.

2. CSP Solar Power Tower

BrightSource Solar Thermal Power Tower

BrightSource Solar Thermal Power Tower

Principle of operation:
This solution is all about maximizing the efficiency from thermal energy to electrical energy (Rankine cycle efficiency).

  • Two dimensional moving mirrors, or heliostats, focuses the sunlight roughly 500 times toward a receiver, containing a working fluid, recently molten salt, located close to the top of the turbine tower.
  • Water is pressurized by a pump from 0,02 Bar to 100 Bar to prepared for the boiler
  • The working fluid driven boiler or evaporator generates dry 550 C steam of the high pressure water to drive the steam turbine which generates the electricity.
  • The lower pressure and lower temperature steam is condensed back to water in a condenser.
  • Thermal energy is stored in a molten salt(a mix of sodium and potassium nitrate) container to be used when the sun is not shining. As a reference a 9 m high and 25 m in diameter molten salt container drives a 100 MW turbine for 4 hours.

Technology strengths:
+ The medium heated during the day can be stored in vessels to keep the turbines running at night to perhaps if the storage cost is reduced, produce electricity 24/7.
+ They claimed earlier to achieve the highest Efficiency.
+ High boiling temperature and small relative receiver area together with large scale turbines enables good price/performance for large scale plants.
+ Lots of research ongoing of lower cost/ high quality mirrors that will also scale with volume.
+ Requires less water than Parabolic trough

Technology threats:
– The mirror cost itself + 2d axis movement and syncronisation of mirrors need to get down in cost.
– There are some safety concerns with reflections from the tower and there are also some environmental concerns regarding bird life and highly concentrated light.
– Will the storage solutions ever get down in cost so that electricity can be produced 24/7?

Technology potential:
This is already becoming a large scale technology and it has had its breakthrough. Success gives volume and then the expensive 2 axis mirrors and the storage solution could be cheap enough.

3. Parabolic trough CSP

Parabolic trough solar thermal power plant

Parabolic trough solar thermal power plant

Andasol 1: Parabolic through power plant

Andasol 1: Parabolic trough power plant

Parabolic Trough Functionality Description

Parabolic Trough Functionality Description

Principle of operation:
A parabolic reflector is used to concentrate sunlight on an insulated tube (Dewar tube) or heat pipe, placed at the focal point, containing coolant which transfers heat from the collectors to the boilers in the power station. The world’s largest parabolic trough facilities, located in the Mojave Desert, consist of nine plants producing 354 megawatts of power at peak output.

Technology strengths:
+ Parabolic trough power plants are the only technology for utilizing solar energy in large power plants that has been commercially proven over a number of years
+ Simple & robust technology
+ Probably still the lowest price/performance of the large scale thermal solutions, especially when looking at maintenance cost and life time.
+ Can easily be combined with other sources electricity production, like natural gas, during cloudy days to produce electricity 24/7

Technology potential:
Likely to be one of the big electricity generating technologies for the future.

Companies using the parabolic trough solution is found here

4. Concentrating Linear Fresnell reflector (CLFR)

One dimensional moving flat deflector for solar thermal electricity

One dimensional moving flat deflector for solar thermal electricity

Principle of Operation:
The Compact Linear Fresnel Reflector (CLFR) solar collector and steam generation system, uses linear flat reflector mirrors to focus the sun’s heat onto elevated receivers, which consist of a system of tubes containing the heated working fluid. Some solutions use water directly as the working fluid to reduce complexity and a heat exchange step.
The working fluid boils pressurized water in the boiler or evaporator, generating high-pressure steam for producing electricity by the turbine.

CLFR Optical principle

CLFR Optical principle

Technology strenghts:

  • Claims to be one of few to use water as a working fluid and that it is animal safe :-) .
  • Mirrors are said to be cheaper than parabolic trough due to the flat design.
  • Easier to maintain and less efficiency reduced shading compared to Parabolic trough due to its flat construction.

Technology threats:

  • A more complex and potentially more expensive solution compared to parabolic trough
  • Does the same thing as parabolic trough and parabolic trough was there first and already have volumes.

Technology potential:
As large as the conventional parabolic trough technology.

Companies using the CLFR solution is found here

5. Two dimensional parabolic dish solar thermal collector or Stirling dish

2D parabolic dish solar thermal plant

2D parabolic dish solar thermal plant

Parabolic dish system

Parabolic dish system

Principle of operation:
Parabolic dish concentrators are similar to trough concentrators, but focus the sunlight on a single point. Dishes can produce much higher temperatures and the small focal heating area reduces the thermal radiation loss, and so, in principle, should produce electricity more efficiently. This technology have not yet had its big breakthrough due to its higher complexity but recent use of the Stirling engine have increased the efficiency and perhaps lowered the price/performance.
More info of the Stirling dish system technology can be found here

Technology strengths:

  • A modular solution providing very high temperatures in a small low thermal radiation area enables a high rankine cycle efficiency and solar irradiation collector efficiency.
  • Requires no water which is a big advantage in the desert
  • Combine the dish with a sterling engine in the focal point and you get the highest efficiency so far with a record of 32%

Technology threats:

  • Complexity and cost (At least initially)
  • Same limitations as photovoltaics with uneven production and no energy storage to produce electricity during night
  • Why did Tessera solar loose lately?

Companies using the Parabolic dish or Sterling solution is found here

NRG Suspends Offshore Development http://www.greenenergyreporter.com/renewables/wind/nrg-suspends-offshore-development/ http://www.greenenergyreporter.com/renewables/wind/nrg-suspends-offshore-development/#comments Wed, 14 Dec 2011 06:15:35 +0000 http://www.greenenergyreporter.com/renewables/wind/nrg-suspends-offshore-development NRG Energy, blaming  a lack of federal subsidies and regulatory uncertainty, has stopped development work supporting its offshore wind projects, including a 200-megawatt initiative in Delaware.

NRG Energy, blaming  a lack of federal subsidies and regulatory uncertainty, has stopped development work supporting its offshore wind projects, including a 200-megawatt initiative in Delaware.

The suspension, NRG said, would impact the Mid-Atlantic Wind Park, a 200-megawatt projects slated for construction off the coast of Delaware.

NRG, which acquired the Mid-Atlantic project as part of its 2009 buyout of New Jersey developer Bluewater Wind, said it’s been forced to scale down its offshore ambitions because it was unable to find a partner to help finance Mid-Atlantic and other projects. The company also blamed the overall regulatory uncertainty and a lack of subsidies. All of these factors made the project unfinanceable and financially untenable, the company said.

NRG said it had terminated the long-term PPA it had signed with Delmarva Power & Light Co., back in 2008.

Despite a deep offshore potential, the U.S. has so far been unable to build a single project. Cape Wind, the country’s pioneering developer of a 486-megawatt project in Massachusetts, has been trying to get an offtaker for half of its unsold output for years and can’t launch construction until it has secured this second PPA. In 2010 National Grid said it would buy half of Cape Wind’s output.

When NRG acquired Bluewater, in 2009,  the outlook for offshore wind was much more positive. The Obama administration had clearly stated that it wanted to populate the U.S. coasts with large wind farms. This political goodwill helped Bluewater receive preferential development rights for a project it was developing off the coast of New Jersey. The project was inline to get a Department of Energy Loan Guarantee.

A little more than two years later, with DOE loan guarantees no longer available and investment and production tax credits not extended, the outlook for U.S. offshore is bleak.

Its seems Bluewater founder, Peter Mandelstam, which two years ago engineered the sale to NRG, hasn’t given up on the Delaware project or on any of his other projects. Trade publication North American Windpower reports that he has been out in Europe, scouting for investors to take over Bluewater’s project pipeline.

First Solar, the U.S. developer of thinfilm photovoltaic panels, has reduced its earnings estimate for this year and next year and has announced plans to cut  100 jobs.

Under its revised guidance, First Solar expects 2011 net sales to range between $2.8 billion and $2.9 billion, down from an initial range  of $3.0 to $3.3 billion. Next year, First Solar forecasts net sales of  $3.7 to   $4.0 billion. According to Bloomberg the company had expected 2012  revenues of $4.06 billion.

The earnings’ cut reflects the challenging market conditions faced by Western solar panel makers, which are competing with a flood of cheap Chinese panels. Specific to  First Solar, overproduction has also  cut into the Arizona company’s revenues. To reverse the situation, last month, First Solar founder Michael Ahearn rejoined the company as interim CEO, replacing Robert Gillette, a former executive with Honeywell International’s aerospace division, who had joined the company three years earlier.

In a prepared statement First Solar’s Ahearn said the company was recalibrating its business “to focus on building and serving sustainable markets rather than pursuing subsidized markets.” He  also remains optimistic about his company’s long-term success. “Our diverse business model and robust project pipeline will help First Solar generate a significant amount of cash in 2012 while improving operational efficiencies,” Ahearn explained.

While these lower costs have helped push solar generation closer to grid parity, it’s also forced a number of capital-intensive solar companies to shutdown. Just this year EverGreen Solar, Solyndra and SpectraWatt all filed for bankruptcy protection, and  on Wednesday the tough market conditions pushed solar module company Solon to seek creditor protection, reports GreenTechMedia.
