Cheap Hydrogen Obtained By Using Ethanol and Sunlight

Not only one time had ethanol been tested as a reliable source of hydrogen. Now, a multi-national team of scientists from Spain, Scotland and New Zealand have devised a method to use ethanol and sunlight to extract hydrogen for use in fuel cells to generate electricity.

HERIC Topology: How a Brilliant Idea Brought 99% Efficiency For Solar Panel Inverters

Brilliant ideas usually don’t need years of hard labor, or at least so it happens most of the time. For example, by implementing a switching trick to a DC to AC current converter used in solar panels, Heribert Schmidt, an electrical engineer (with a doctorate), from the Fraunhofer Institute for Solar Energy Systems has managed to halve inverter losses, bringing the efficiency to 98 percent.

MIT Engineered Virus Could Make Solar Cells More Efficient

Viruses are mostly seen as the bad side of nature, the fallen creation or just that unwanted flu during those sunny days when you were supposed to go play outside. For Angela Belcher viruses are working tools, since she and her MIT colleagues have just found a way to guide some of them so they make solar cells more efficient, by as much as a third.

Meteosat Used to Detect Faulty Solar Panel Power Stations

Italy is known for its plans to develop photovoltaic power as one of their main sources of energy. Having such a wide experience in solar power harvesting, several issues arise regarding the solar panels’ maintenance. Every PV plant has a sensor verifying the quantity of light arriving at its location at any given moment during the day.
