HALE-D: Solar Powered Unmanned Aircraft Helps U.S. Soldiers Communicate

The U.S. Army and Lockheed Martin have developed the first-of-its kind unmanned solar-powered aerial vehicle. Dubbed the High Altitude Long Endurance-Demonstrator (HALE-D), the solar-powered sky cruiser has been successfully launched at 5:47 a.m. out of the Airdock in Akron, Ohio.

New MIT Approach Towards Concentrated Solar Yields Cheaper Power

Large mirror arrays that concentrate light on a tank have been made before, but now a team at the MIT has designed a system that simplifies what has been done before and also makes it cheap for concentrated solar power to enter our homes, rivaling the price of coal.

MIT Researchers Invent Solar Cells That Transform Heat Into Electricity

If you thought photovoltaics can only get energy from the Sun, then you were wrong. An MIT team of researchers have invented a device that produces electricity from heat. The process uses the photovoltaic effect as the middleman and is three times more efficient than the most efficient lithium ion batteries on market today.

Gemasolar Finishes Building Molten Salt – Backed Solar Power Plant in Spain

The construction of world’s first solar power plant capable of producing clean energy all day and night has finally been finished. According to Gemasolar, the company behind the project, the solar power plant is able to generate electricity during the day and also the night because it has 15 hours of energy storage to back it up.

Record: AltaDevices Brags 28.2 Percent Efficient Gallium Arsenide Solar Cell

A new solar cell efficiency record has been achieved by a startup CA-based company called Alta Devices. Previously unknown, the Santa Clara firm brags an efficiency of 28.2 percent for their gallium-arsenide solar cell, a number 2 percent higher than last year’s previous record, and could eventually bring down the costs of solar power to make it compete with coal and gas.

New Colloidal Quantum Dots Solar Cells Gather Visible and Infrared Light

A solar cell developed at the Unversity of Toronto, Canada, is able to harvest both visible and infrared light and can theoretically achieve efficiencies of up to 42 percent. Their tandem solar cell is based on colloidal quantum dots (CQD), and the team has been led by Professor Ted Sargent, a Professor of Electrical and Computer Engineering.

Project Amp to Become United States' Largest Rooftop Solar Project

Since 2009, Prologis, a leading global provider of industrial real estate, has been installing solar photovoltaic cells on the roofs of their own properties. Now they come up with a project, named Project Amp, that aims to install solar panels on the rooftops of 750 buildings across the US to produce 733MW of clean power.

Voltaic Spark: 8-Watt Solar Powered Carrying Case for iPads and Other Gadgets

I’ve been writing about Nokia testing a solar powered version of one of their cellphones just the other day, and thought it’s a pretty stupid idea to apply solar cells on phones since they’re kept mostly inside pockets, and they aren’t transparent. Today I found out that a company called Voltaic is releasing a solar powered carrying case for tablets – the Spark.
