    • Nuclear Photonics: Gamma Rays Search for Concealed Nuclear Threats (ScienceDaily)- April 27, 2011
    • Gamma rays are the most energetic type of light wave and can penetrate through lead and other thick containers. A powerful new source of gamma rays will allow officials to search for hidden reactor fuel/nuclear bomb material. These gamma rays, called MEGa-rays (for mono-energetic gamma rays), are made by using a beam of fast-moving electrons to convert laser photons (light at a lesser energy) into the gamma ray part of the spectrum...

    • BrightSource Energy Files $250 Million IPO (TheEnergyCollective)- April 26, 2011
    • BrightSource Energy, Inc. a utility-scale solar developer, has filed a US$250 million initial public offering (IPO). The California-based solar thermal developer has several intriguing qualities; however, these are saddled along with a few areas of concern. BrightSource sports a significant list of powerful investors and partners including: Google, Inc., Chevron, Alstom, NRG Solar, Vantage Point Capital Partners, Morgan Stanley and Bechtel. All totaled, the company has raised US $530 million..... More...
    • Solar power goes viral: Modified virus improves solar-cell efficiency by one-third (PhysOrg)- April 25, 2011
    • Researchers at MIT have found a way to make significant improvements to the power-conversion efficiency of solar cells by enlisting the services of tiny viruses to perform detailed assembly work at the microscopic level. In a solar cell, sunlight hits a light-harvesting material, causing it to release electrons that can be harnessed to produce an electric current. The new MIT research... More...
    • Laser Sparks Revolution in Internal Combustion Engines (ScienceDaily)- April 21, 2011
    • For more than 150 years, spark plugs have powered internal combustion engines. Automakers are now one step closer to being able to replace this long-standing technology with laser igniters, which will enable cleaner, more efficient, and more economical vehicles. In the past, lasers strong enough to ignite an engine's air-fuel mixtures were too large to fit under an automobile's hood. At this year's Conference on Lasers and Electro Optics... More...
    • Discovery could lead to 'optical battery' (United Press International)- April 19, 2011
    • U.S. researchers say an unexpected magnetic effect of light could lead to solar power without traditional semiconductor-based solar cells. The finding could lead to a way to make an "optical battery," University of Michigan researcher Stephen Rand said. The findings fly in the face of long-held tenets in physics about the properties of light, a university release said Tuesday... More...
    • On the way to hydrogen storage? (PhysOrg)- April 19, 2011
    • The car of the future could be propelled by a fuel cell powered with hydrogen. But what will the fuel tank look like? Hydrogen gas is not only explosive but also very space-consuming. Storage in the form of very dense solid metal hydrides is a particularly safe alternative that accommodates the gas in a manageable volume. As the storage tank should also not be too heavy and expensive, solid-state chemists worldwide focus on... More...
    • Scientists finely control methane combustion to get different products (PhysOrg)- April 14, 2011
    • Scientists have discovered a method to control the gas-phase selective catalytic combustion of methane, so finely that if done at room temperature the reaction produces ethylene, while at lower temperatures it yields formaldehyde. The process involves using gold dimer cations as catalysts — that is, positively charged diatomic gold clusters. Being able to catalyze these reactions, at or below room temperature, may lead to significant cost savings in... More...
    • Cold asteroids may have a soft heart (PhysOrg)- April 8, 2011
    • A new analysis of one of the most well-known meteorites on Earth provides strong evidence that the prevailing view of many asteroids is wrong. Rather than randomly mixed blobs of rock and dust stuck together, it appears that the asteroid that was the source of the Allende meteorite was large enough to have had a molten core, even though its surface remained cold and solid...

    • Nanoparticles Improve Solar Collection Efficiency (ScienceDaily)- April 5, 2011
    • Using minute graphite particles 1000 times smaller than the width of a human hair, mechanical engineers at Arizona State University hope to boost the efficiency -- and profitability -- of solar power plants. Photovoltaic (PV) solar panels are popping up more and more on rooftops, but they're not necessarily the best solar power solution... More...
    • Pinnacle Engines Introduces Its Ultra-Efficient Combustion Engine (The Street)- March 31, 2011
    • Pinnacle Engines today unveiled plans to commercialize a breakthrough ultra-efficient engine by 2013. The new engine design enables significant reductions in fuel consumption and greenhouse gas emissions without increasing vehicle cost. Pinnacle also announced it has raised $13.5 million in venture funding from NEA, Bessemer Venture Partners and Infield Capital. While electrification of the worldwide vehicle fleet presents a promising long-term solution... More...
