São Paulo’s Ecovila Residence Receives Brazil’s First Solar Track

The Ecovila, located on the coast of São Paulo, is the first residential structure in Brazil to install solar panels that follow the motion of the sun. The solar system, along with two wind turbines, will provide enough energy for lighting and water pumping to support the entire village consisting of 58 houses. The system installed has the capacity to capture 350,000 liters of rainwater, and the design of the village boasts cross ventilation, 15 square meters of green area per resident, and an organic garden.

Why Google Invests in Clean Energy

Last year, Google invested more than $915 million in clean energy projects — solar, wind and transmission.

That’s a lot of money, even for Google, which had $38 billion in revenues in 2011. The investments don’t appear to be core to the company’s mission of organizing information, and they have attracted criticism, as well as some careless reporting, implying that the Internet giant is exiting the alternative energy business.

India Leads World In Green Power Growth For 2011

India’s remarkable growth in solar power, which TreeHugger has been following for some time, has gained the nation another superlative: According to new analysis by Bloomberg New Energy Finance, India led the world in 2011 for green power growth.

Solar Powered Vehicle for a green ride in deserts

Designer Omer Sagiv’s futuristic Solar Powered Vehicle (SPV) is an ideal vehicle for long rides in deserts or other open lands. The SPV is a typical solar vehicle design. The aluminum structure mounts plenty of flexible thin film modules, which can generate much energy for long rides. In form, the SPV almost resembles Nuon solar car, developed by Delft University.

A hydrogen fueling station powered by the wind

By building a wind turbine to power a hydrogen production and fueling station, a little hamlet in Long Island is positioning itself as the bellwether for carbon-neutral transportation.

The town of Hempstead, New York on Long Island erected a 121 foot tall turbine last December on the township’s Department of Conservation and Waterways land to take advantage of powerful Atlantic winds and power the hydrogen and natural gas fueling station it built in 2009. The turbine can generate up to 180 megawatts of power per year, and presents an estimated hydrogen fuel and energy cost savings of $40,000 per year.

It’s easy to think about modules as singular units of power output, but the reality is that they are a collection of diverse components, each with influence over the end system’s total cost and performance. For DuPont, its focus is of course on the materials side, from metallization pastes used to form contacts on the solar cell, to backsheet materials that protect the panels themselves.

Stanford pioneering a wireless electric highway

Stanford researches may have solved the problem of range anxiety by wireless charging technology that could one day create an electric highway.

Wireless recharging already is used by some electric vehicle charging stations to fill up batteries without cords or plugging into an outlet. MIT helped pioneer this technology and spun it off into a wireless charging startup, WiTricity. However, Stanford researchers improved on this concept and devised a way to transmit 10 kilowatts of electric power across a 6.5-foot distance with minimal energy loss. By overcoming transmitting electricity across a significant distance, researchers will make it possible to pave a highway with wireless conduits that can provide addition power to EVs and let them operate indefinitely.

Green solar cell is made from plants

In a mashup of biology and electronics, researchers said they’ve made progress in making low-cost solar cell from plants.

A paper published in Scientific Reports today describes an improved method for making electricity-producing “biophotovoltaics” without the sophisticated laboratory equipment previously needed. Researchers said custom-designed chemicals could be mixed with green plants, even grass clippings, to create a photovoltaic material by harnessing photosynthesis.

Charge your phone using pedal power with the K-TOR Power Box

K-TOR has added a new portable charging device to its lineup. The new Power Box puts your legs to work toward converting kinetic energy to electricity. Use it enough and you might just get your weekly workout. It is quite simply a pedal-powered generator equipped with a dual-pronged outlet so that you can plug in an AC adapter and charge your device directly from your leg power. The box works for devices rated 20W and below, including low-power netbooks, tablets, smartphones, video devices and portable game systems.

Mexican student envisions energy generating satellite

As our conventional sources of energy are about to go extinct, scientists are developing unique and indifferent technologies to meet the global demand of energy. Carl Peart, a Mexican student, entered the ‘Create the Future Design Contest, 2011‘, with this unique design to produce clean energy. Named ‘Solar collection and Transfer Satellite’, it uses the system of Electro Mechanical Batteries to store energy, which is collected by the solar panels installed on the satellite. EMBs are simple and have amazing potential to store energy.
