Renewable Power News » Gadgets http://www.renewablepowernews.com News about Solar, Wind and alternative green power technologies Sun, 28 Oct 2012 17:30:29 +0000 en hourly 1 http://wordpress.org/?v=3.3.1 Say Good-bye to Flat Batteries http://www.renewablepowernews.com/archives/3202 http://www.renewablepowernews.com/archives/3202#comments Mon, 20 Aug 2012 18:58:38 +0000 Jimmy Eriksson http://www.renewablepowernews.com/?p=3202 A recent system has been developed to check the charge, age and reliability of the battery.

Imagine yourself, driving your car and suddenly the car’s battery goes flat. This would be terrible news, before the battery went flat you were a happy driver, after that you become a furious pedestrian. Probably, your plans will be delayed, and your mood will worsen. All this because of a flat battery! Imagine if this problem could be avoided; in fact, this type of disturbing situation can be circumvented. Professor Dr. Constantinos Sourkounis and Philip Dost are heading a group of scientists from the RUB’s working group for the Energy Systems Technology and Power Mechatronics; together with Isabellenhütte Heusler GmbH & Co.KG they managed to develop a primary warning system.

This new battery supervision system available for lead-acid collectors is designated to avoid drivers from a complete breakdown and a lot of trouble. The driver is briefed using an on-board computer system if a modification of battery or a new car battery is about to occur. When this battery management system is compared to others built in the past, they found out that this new system does not require successive reprogramming in the garage (what was very disturbing in previous systems). Professor Sourkounis said the new system will automatically recognize and measure the battery’s parameters, in the first trip. Different information is provided by the system; information such as: the age, charge and durability of the car’s battery. Recent cars require more and more amounts of energy, so this new and innovate system is specially required for this type of situation (excluding headlights and the combustion motor) dozens of minor electric motors and small sensors will need electrical power to function.

Professor Sourkounis said that big capacity accumulators mean increased service life and also increased age. Batteries destined to high-performance vehicles are more expensive. However, expensively does not necessarily mean they are completely resistant to extended periods of non-use or even too cold. Since a battery will not last forever it is recommended and convenient to receive constant updates about the battery’s current status. With this new battery management system, you will be able to predict if a new start is possible before the engine is turned off all this without the complicated need to adjust difficult parameters (e.g. battery’s diffusion capacity). Additionally a new innovative warning functionality will allow the driver to be warned if the battery needs to be recharged.

Isabellenhütte Heusler GmbH & Co.KG is the industrial partner of the Bochum researchers. This supplier of automobile components is the leader in the market for accuracy measuring resistors. These components are crucial part of battery management system because they will allow the status of the battery to be accurately measured.

Making PV from Any Semiconductor http://www.renewablepowernews.com/archives/3198 http://www.renewablepowernews.com/archives/3198#comments Sun, 19 Aug 2012 22:58:29 +0000 Jimmy Eriksson http://www.renewablepowernews.com/?p=3198 A new technology has been developed by researchers from the United States Department of Energy, the Berkeley Lab and the University of California (Berkeley). This technology will be capable of solving one of the most complicated problems concerning solar energy; that problem is high-cost production. This recent and innovative technology will enable the production of low-cost solar cells. In addition, these cells will be extremely effective when it comes to generating electrical energy. In the past metal oxides such as phosphides or sulfides were considered inappropriate for cells because they couldn’t properly fit chemical means.

The physicist Alex Zettl who headed this outstanding study alongside with his colleague Feng Wang says now is the right time to take bad material and give them a good and proper use; their technology gives them the possibility to overcome the difficulty of tailor much earth abundant when it comes to chemical tailoring. They can tailor those materials by simply applying an electric field.

Alex Zettl is the corresponding author of a paper published in the journal Nano Letters; the paper’s title is ‘Screening-Engineered Field-Effect Solar Cells’,’ and it is co-authored by Onur Ergen, Steven Byrnes, William Regan, Will Gannett, Feng Wang and Oscar Vazquez-Mena Alex Zettl also holds joint arrangements with the Division of Materials Science (Berkeley Lab), and with the Physics Department (UC Berkeley) there he leads the COINS, stands for Center of Integrated Nanomechanical Systems.

Using semiconductor materials, solar cells convert solar energy into electricity; this shows the PV (Photovoltaic) effect; which means that those cells absorb photons, and then they release electrons. Later, those electrons can be directed into an electric current. Obviously, PV is the latest resource for green, clean and renewable energy; however, nowadays technologies use limited and expensive semiconductors (e.g. copper indium gallium selenide; large crystals of silicone or cadmium Telluride). Substances like these can be difficult to fabric into devices, and they are costly.

Zettl said that international interest in solar energy slowed because the cost/efficiency ratio is very low; by using their technology they will decrease not only the costs related to production of such material. But also the complexity when it comes to the fabrication; this will result in an international increased use and interested in this type of environment-friendly energy. This recent technology is named SFPV (SFPV stands for Screening Engineered Field Effect Photovoltaic); the technology was given this name because it uses an electric field effect that is a well-known phenomenon; where the concentration of charge-carries present in a semiconductor is modified by applying an electric field. Using the Screening Engineered Field Effect Photovoltaic technology, a wisely planned partially screening top conductor lets the gate electric field infiltrates the electrode and more homogeneously control the semiconductor transporter type.

William Regan (lead author) said that their technology needs only gate and conductor deposition; without the need of using chemical doping, high temperatures, ion implantation or other harmful and expensive procedures. According to Regan, the key to their success is the slight screening of the gate field (that was accomplished by using geometric shaping of the top conductor). This allows carrier modulation of the semiconductor and electrical contact to be performed at the same time.

According to the SFPV system, the top electrode’s structure is modified; that will allow at least one of the conductor’s dimensions to be restricted. Berkeley researchers managed to modify the electrode contact into thin fingers (working with copper oxide); in a different configuration (working with silicon), they built the top contact ultra-fine through the surface. Possessing the necessary narrow fingers the gate field will generate a low electrical opposition inversion ‘coat’ in the middle of the fingers and a possible barrier underneath them. A homogeneously tinny top contact will enable gate fields to infiltrate and turn upside down or up to the underlying semiconductor.

Feng Wang (co-author) said that their demonstrations showed that electrically stable p-n junctions could be accomplished with almost any semiconductor and any conductor material using the application to a gate field; once the conductor is properly geometrically organized. Researchers were capable of demonstrating the Screening Engineered Field Effect Photovoltaic effect in a self gating structure;

Regan stated that self gating structure will eliminate the need of having an outside gate power font; this will result in simplification in the implementation of the Screening Engineered Field Effect Photovoltaic devices. Regan also adds to his statement the gate will have another two important roles


- The gate will serve as an anti-reflection coat;

- Secondly, as a necessary and common feature for high-productivity PVs.

Both the Department of Energy Office of Science and the National Science Foundation supported this research.

Five Breakthroughs In Solar Technology http://www.renewablepowernews.com/archives/3161 http://www.renewablepowernews.com/archives/3161#comments Sun, 22 Jul 2012 18:18:31 +0000 Jimmy Eriksson http://www.renewablepowernews.com/?p=3161 Constant progress in innovations of solar technology has surprised both solar experts and newcomers alike. Improvement is not only confined to the more traditional solar technology but also involves new handheld devices and applications. These innovations guarantee that solar will eventually replace fossil fuels as the clean-energy source of choice.

The Solar Kindle

At this year’s Consumer Electronics Show, the SolarKindle made its debut as Amazon’s latest innovation in the field of mobile devices and solar technology. The SolarKindle is an innovation of Amazon’s ever-popular Kindle. The e-reader has a solar cover able to absorb enough energy from an hour of sunlight to power the tablet for three days. Moreover, the SolarKindle’s cover can provide sufficient energy to the mobile device for three months under normal sunlight. Users no longer have to worry about finding electrical ports to charge their Kindle.

Artificial Leaf

One of the most innovative additions to solar technology is the Artificial Leaf created by MIT researcher David Nocera. Like its name describes, the Leaf simulates a real leaf whereby it goes through a photosynthesis-like mechanism. During this process, the Leaf absorbs solar energy and uses this to break down water molecules into hydrogen and oxygen. The gases produced can be stored in a fuel cell to make off-grid living possible. What’s more, the Leaf performs 10 times better than a natural leaf. Nocera develops products that could eventually provide electricity to the poor in Third-World countries through his company Sun Catalyix. His creations are expected to be of commercial use very soon.

The Lotus Position

Italian architect Giancarlo Zema, well-known for his forward-looking creations for semi-submerged architecture, has teamed up with architectural design house Luminexence to create the multi-purpose “Lotus.” The Lotus functions as both a charging kiosk for an electric vehicle and as an LED street lamp. A segmented design, a small segment of the Lotus can produce 500 watts of electricity while the greater segments are able to generate 2.8 kilowatts. Not just that, the greater segments can be used as shelters for vehicles. Zema and the architects dream that one day this will transform public spaces, especially parking spaces to environmentally sound areas.

Dow Powerhouse Shingle

One of the latest must-have in solar technology has got to be Dow’s new solar shingles. The building had embedded photovoltaic (BIPV), which allows solar to blend in with its environment. These shingles not only function as a rooftop but also as a solar installation. Besides, the shingles can be conveniently installed by regular roofing contractors. The shingles made its debut in the market in Colorado in the last quarter of 2011. It is expected to make its appearance in the other markets soon.

Belgium’s Solar Tunnel

For the first time in European history, a high-speed rail line is powered by clean energy. The Belgian railway infrastructure is powered by 16,000 solar panels along two miles of the man-made tunnel. The clean-energy powers the lighting, heating and signalling system of the route from Antwerp to Amsterdam. The collaboration between municipalities, installer Solar Power Systems and solar developer Enfinity are expected to generate above 3,000 MW of electricity annually. This is enough to power 950 homes.

World’s First Plug-and-Play Solar Panels Launched http://www.renewablepowernews.com/archives/3048 http://www.renewablepowernews.com/archives/3048#comments Sun, 01 Apr 2012 23:41:28 +0000 Jimmy Eriksson http://www.renewablepowernews.com/?p=3048 Westinghouse has launched the world’s first fully integrated plug-and-play solar panels. The company’s innovative trademarked instant connection system eliminates panel-to-panel wiring and racking. The company claims their system reduces installation costs by 50%.

Last week, the designer and manufacturer of solar power systems, Westinghouse Solar, announced the release of a new line of solar panels under the trade name Instant Connect. The system promises faster and easier rooftop installations than commonly available products.

Westinghouse Solar’s new product is one in a long list of innovations by the company that developed and integrated racking directly into the solar panels in 2007. They also introduced the industry’s first UL-approved AC solar panel in 2009. Instant Connect is the company’s first plug-and-play product. This solar panel eliminates time-consuming and sometimes difficult connection of panel-to-panel wiring for residential AC systems and commercial DC systems.

Westinghouse Solar has developed this product with innovative sets of UL-approved electrical connectors that are integrated directly into the sides of each solar panel. This allows installers on roofs to plug solar panels together easily; various patents have already been established for the. Westinghouse Solar’s Instant Connect includes frames of the solar panels and splices that connect the solar panels together. They stipulate precision alignments of different electrical connectors and eliminate manual wiring and cabling.

Installation of current standard solar panels

Currently, installation of solar panels requires assembly of many individual parts, which include long sections of aluminium or steel racking, electrical conduit to separate the high-voltage DC wires. The list of tasks involved is lengthy and costly.

Installation can be challenging particularly given assembly on roof environments as there is risk of fall. The core problem of rooftop installation is that manufacturers never considered easy system packages that reduce parts and make installation easy. Another obstacle is that installation components only fit individual manufacturers’ products leaving consumers not much choice in the selection process of parts and assembly solutions.

Westinghouse Solar’s alternative to standard systems

The solar designer explains to have had the idea of Instant Connect, ten years ago. The idea of Westinghouse Solar’s product was to develop an installation package, which reduced the number of individual components. The aim was to develop a system which included an integrated racking solution and ease the installation of solar panels on rooftops. Instant Connect does not require an underlying sub structure. The wiring is done through special connectors on the sides of the panels. Westinghouse patented this concept, and in 2007 began to introduce first products incorporating parts of the patent.

Currently, rooftop solar panels have become reasonably cheap and easy to install. Westinghouse claims that their new product allows electricians, HVAC contractors and skilled Do-It-Yourself (DIY) to install a system without difficulties.

Instant Connect can be added on to enlarge a smaller panel system at a later stage. Westinghouse Solar Power Systems, including Instant Connect are available through larger home improvement and DIY retailers.

Barry Cinnamon, CEO of Westinghouse Solar, says the pressure to reduce costs of fully-installed rooftop solar systems remains high. The Westinghouse Solar suggests that their innovative system can lower the immediate installation costs by an estimated $0.25/watt. In other words, this would render solar energy installation much more cost attractive

The system is now available for customer in North America.

About Westinghouse Solar:

The designer and manufacturer of solar power systems, Westinghouse Solar, has developed a system in 2007, which integrated racking, grounding and wiring instantly into the photovoltaic panels. The company branded their product system originally “Andalay” and won industry acclaim.

In 2009 Westinghouse Solar launched another product following the same concept as “Andalay.” This time it integrated AC solar panels which lead to a decrease in the volume of components required for solar panel installation by an estimated 80%. The product’s easy installation also lowered installation and labour costs by nearly 50%.

Westinghouse Solar won the 2009 Popular Mechanics Breakthrough Award for this product. It also became the industry’s most widely installed AC solar panel.

With this year’s launch of Instant Connect, Westinghouse Solar is providing AC and DC configurations, which are the only panels with integrated racking, grounding and wiring. The company prides itself on providing the best combination of performance, safety and sustained reliability.

Innovative Batteries With Potential of Low Cost, & More efficient Solar Energy http://www.renewablepowernews.com/archives/3030 http://www.renewablepowernews.com/archives/3030#comments Tue, 27 Mar 2012 23:27:03 +0000 Jimmy Eriksson http://www.renewablepowernews.com/?p=3030 A new type of battery with the potential of increasing the efficiency and cutting the costs of solar power was unveiled thanks to collaboration between the University of Southampton and lithium battery; technology company REAP systems. The latter is the sponsor of the research project which is Led by Yue Wu, a MSc Sustainable Energy Technologies student under the supervision of Dr Carlos Ponce de Leon, Professor Tom Markvart and Dr John Low (an employee at the Institution’s Research Institute for Industry, RIfI). The project focused on the use of lithium batteries for purposes of energy storage in photovoltaic systems.

MSc student Yue Wu indicates that although most photovoltaic systems employ lead-acid batteries for energy storage purposes, lithium batteries, especially the LiFePO4 types, are more efficient when used as energy storage devices.

In order to collect data, a custom-made battery management system provided by Reap systems was used. A lithium iron phosphate battery was connected to a photovoltaic system which was fixed to one of the buildings in the University.

Yue further adds, besides lithium batteries having an efficiency of 95% compared to that of the commonly used lead-acid batteries, which is 80%, the former has a relatively less weight and are long lasting. In general, the maximum charge/discharge cycles of this new battery is 1,600, indicating that replacement would be infrequent.

Although the LiFePO4 battery can increase the efficiency of solar power systems, further investigations need to be done before commercial rollout is done. The installation and maintenance costs of the technology need to be scrutinized. In light of this, Dr. Carlos Ponce de Leon and Dr. John Low contemplate conducting more investigations on the project with a new group of Master’s students.

The founder of REAPsystems, Dr Dennis Doerffel who is also a former researcher at the University of Southampton says that energy storage devices such as batteries in both renewable and non-renewable energy sources contribute greatly in the utilization of energy. He further reiterates that LiFePO4 beat the conventional lead-acid batteries in many aspects. This new battery beat its former counterparts in terms of efficiency, extended lifetime, lighter weight and less cost per unit. Dr Doerffel concludes by saying that this battery has the potential of commercial application in both photovoltaic systems and in a variety of other renewable-energy systems. Source: E-science News

Cook Food With A Solar Stovetop http://www.renewablepowernews.com/archives/2252 http://www.renewablepowernews.com/archives/2252#comments Mon, 14 Feb 2011 23:24:53 +0000 Jimmy Eriksson http://www.renewablepowernews.com/?p=2252 The new off the grid global cooking style – Hot Liner Solar Cooker Stove – by Yonggu Do & Eunha SEO from Yanko Design can replace the old fashioned solar ovens, successfully.

In 2010, at Seoul International Design Competition, co-hosted by Designboom, Hot Liner got the Golden Haechi Award because of its original concept, which is based on a unique way of building, designed for those people who have no access to reliable electricity.


The Hot line consists in a flexible solar panel, rigid, a solar cell holder, a battery, a heat coil and a magnetic strip at each end, which can connect one to the other.

It can take any shape, depending on the size of the cooking pots. For a small cooking pot, it is necessary only a liner in a ring shape and for larger ones, 2 liners fit together. The Hot Liner is becoming an off-grid, dual burner stovetop.

When Hot Liner must be recharged, it can be put flat on the ground or hung in a tree to capture the solar energy. This is really a revolutionary type of technology.

Plug-in electric hybrid Cars – Cost Efficient and Environmentally Friendly http://www.renewablepowernews.com/archives/2224 http://www.renewablepowernews.com/archives/2224#comments Sun, 06 Feb 2011 17:46:24 +0000 Jimmy Eriksson http://www.renewablepowernews.com/?p=2224 New modern plug-in electric hybrid vehicles are similar to conventional cars such as Toyota Prius and Lexus. The only difference is the size of the batteries used in these modern cars. In addition, these batteries are more expensive. They have an advanced system which even allows re-charging to be done at a parking. This would increase the volume of kilometres that can be covered solely with the electric engine. The vehicles have the advantage of typical hybrid as well as electric vehicles. These car models can also help in the introduction process of transport electrification.

There exists two different types of hybrid cars. There is the plug-in hybrid model where diesel and gasoline engines take over when the battery of the electric engine is finished. The second type of plug-in hybrid work together with the gasoline engine in the sense that the diesel or gasoline engine will charge the electric engine to improve the autonomity of the car.

Unfortunately, due to technical disadvantages the electric engine is currently only appropriate for short distance. However, the conventional engines can help by constantly recharging the electric engines while driving. This will boost the potential distance that the electric engine can cover; it can go up to 450 Km or even more. The best part with electric engines is that they produce no emissions.

The use of electric engines can make the transport sector really green. Let’s say that cars are recharged during the evening with electricity coming from pure sources such as wind energy. ‘More advanced electric vehicles do even generate energy from braking’. This is a source of energy, which is wasted by conventional gasoline or diesel vehicles. This makes electric engines perfect for short and urban distance where lots of braking is done.

http://www.renewablepowernews.com/archives/2216

A new model produced by General Motors is Volt. It has an electric engine which can provide 64 Kms of daily travelling simply by its advanced autonomy. In case the car is used to travel across long distances than the gasoline engine will simply help in charging the battery for the electric engine.

General Motors estimates that the cost of driving a Volt with the use of battery energy will only cost about two cents of a euro in comparison to 12 cents of a euro for a typical gasoline vehicle. The cost difference is gigantic. A typical driver who covers 60 kms a day or 22,000 km per annum will save 2,200 € every year. This could help to pay for the additional cost associated with the battery of the car. In other words, driving a Volt is six times cheaper than a conventional vehicle per km.

On average, the cars that are sold in Europe – 2006 – consume roughly 6.5 liters for every 100 kms covered. On the other hand, a plug-in hybrid vehicle can drive 50 kms with electricity, and the remaining 50 would be covered with around 2.5 liters.

A daily trip is usually less than 60km. Using hybrid vehicles could generate remarkable changes in terms of cost. For short distance recharging could be done at parking. This means that fossil fuel wouldn’t be needed when travelling in urban regions.

Electric or hybrid vehicles are definitely cost-efficient. The car is cost-efficient and doesn’t generate emissions while driving on the electric engine.

Electric Vehicles – Some Formulas For Charging Batteries http://www.renewablepowernews.com/archives/2216 http://www.renewablepowernews.com/archives/2216#comments Thu, 03 Feb 2011 22:59:35 +0000 Jimmy Eriksson http://www.renewablepowernews.com/?p=2216 There is really progress going on in the field of electric engines. Electric engines are already four times better than internal combustion engines. The technology to bring pure plug-in electric vehicles to the road does already exist. The only restrain is the presence of efficient battery solutions; batteries allowing recharging to be done at an affordable cost. The upcoming years, will see a drastic change in the composition of cars on the road. Most automobile companies are already developing special electric car models.

An advantage of electric engines is that they make use of the energy generated from braking. This heat is usually wasted. This means that these vehicles are perfect for urban distances where lots of braking is done.

In addition, there are fewer mechanical components – this reduces the operation cost of the vehicles. The cost of driving electric vehicles has for the first time in history decreased to a highly competitive cost. Electric vehicles are even more cost-effective than typical diesel and gasoline vehicles. This motivates the development of the electrification of the transportation sector.

Of course, transforming the road system will take time and requires creativity. Irrespective of the amount of effort required to realise the introduction of greener cars has a phenomenal profit potential.

Plans have already been proposed in Australia, Portugal, Israel, Ireland, Denmark, France and New Zealand. In other areas such as in Japan, Germany and in states of US like California and Hawaii, pilot programs have already been introduced. Spain is planning to progress with pilot programs in 2012. The U.S, Obama’s administration is steadily promoting plug in hybrid and electric cars to the market – news is expected soon -.

To charge electric vehicles, there are two feasible solutions – a single large electric plug-in engine or several smaller engines placed to each wheel. The use of one engine in the electric vehicles will make the cars more powerful and alike to contemporary cars. However, they have a downfall, related to its inefficient reaction to friction.

The electric vehicles could have engines in the tires. This would reduce the loss of energy (friction) in respect to the single engine solution. Unfortunately, several small engines would only be appropriate for small cars as larger vehicles need more power and thus a larger engine.

The problem of electric cars might come in the motivation to transform and redefine the way these cars are re-filled. Instead of recharging cars for hours, the batteries could simply be changed. It would practically take the same degree of time to change a battery to that of re-fuelling.

The focus is to provide low battery costs. One solution is to provide batteries at a monthly fee or even the car itself for a periodic fee. This would make the car industry alike to that of the phone market. Vehicles could be purchased cheaply in this way. Battery charging, maintenance, replacement infrastructure and support would be provided for a monthly fee.

On average in Europe approximately 12,000 Euros are spent to buy a car and 30,000 Litres of fuel are needed over a year. This brings the cost to roughly 30,000 to 35,000 Euros per year. Research suggests that fuel is three times as expensive as the car itself. On the other hand, an electric car battery would merely cost 7,000 Euros. The electricity cost of charging the battery would amount to 2,000 during the operation life of the battery. In other words, it is only 30 percent of the cost of fuel consumed by typical cars.

In addition, the cost of electricity from renewable sources of energy and battery tend to fall year on year. This mean that the cost of electric cars will experience a diminishing cost in all it senses – the vehicle, electricity and batteries –

For an electric car to drive 100 kms, it will need roughly 10 to 20 kilowatt hour. This is tantamount to 2 Euros. A gasoline or diesel car would make this distance at the cost of 8 Euros. This makes electric vehicles extremely competitive. The only drawback is the high fixed cost of the battery. In order, to deal with these problems formulas used in the cellular phone sector, is currently a competitive option. The battery could be leased similarly to subscription to various phone networks or internet packages. The battery companies will then only change battery at the re-charging stations.

The introduction of electric cars needs a new environment. The solutions lie in either battery replacement stations or charging spots on parking areas (near to cars). Unfortunately, these things aren’t available yet. The transport electrification plans need to be introduced effectively to make sure that the market for electric cars strives.

Strong collaboration between manufacturers and governments are fundamental. Countries like Australia, Iceland, Portugal, Ireland, Denmark, Israel, and in the U.S. San Francisco and Hawaii are taking critical steps. Besides, pilot projects are steadily progressing on countries like UK, France, China, Italy and Germany.

The dream to go Green: Aran Islanders try out Electric Cars http://www.renewablepowernews.com/archives/2165 http://www.renewablepowernews.com/archives/2165#comments Thu, 20 Jan 2011 21:59:53 +0000 Jimmy Eriksson http://www.renewablepowernews.com/?p=2165 The Aran Islands have been selected for trying out the electric car. It is located off the west coast of Ireland and is thought to be ideal for such tests.

Aran Islands were thought to be the perfect site for such testing as there is much wind. Also the relentless waves drum up the energy.

The project is over a period of three years. It consists of given the eight householders living on the islands a vivid orange electric car.

The objective of the project is to ultimately produce sufficient energy to generate heat, electricity as well as transport for the various islands.

Varied households will be selected to participate in the project on a yearly basis with the aim to make use of absolutely no carbon fuel in the years to come.

In accordance to Inis Oirr Island Cooperative’s manager, Paddy Crowe, the project’s bottom line is to make all the islands become self-sustainable.

He furthermore adds that they have done all that is in their hands to become green as far as possible. They have even insulated the houses as well as make use of solar panels.

Paddy Crowe advances that the islands were the perfect testing site for the electric cars. This is so because the amount of fuel that will be saved is measurable on the islands as all the fuel to be used will need to be brought to the islands.

He declares that they are completely controlling the situation. All the fuel to be used will be brought in the islands by ferry. Measuring the fuel use in a town is far more difficult compared to on an island.

Mr Crowe stated that the families that will be given the cars would make use of them on a regular basis.

This pilot project has take shape due to the partnership between the Department of Community, Rural and Gaeltacht Affairs and Sustainable Energy Ireland.

Out of the six Mega e-City cars will be sent to Inis Mor and one to Inis Oirr and Inis Meain.

The drivers of the vehicles will require paying a lease of 12 euro. The principal costs will consist of paying 400 euro. This will be for installing a charge point near every house.

The general operation cost per annum is anticipated to be approximately 90 euro.

Apple Might Soon Power Appliances with Solar Energy http://www.renewablepowernews.com/archives/2150 http://www.renewablepowernews.com/archives/2150#comments Sun, 16 Jan 2011 22:53:51 +0000 Jimmy Eriksson http://www.renewablepowernews.com/?p=2150 Recently, Apple earned their patent for the technology enabling electronic gadget to be powered with the use of solar energy.
