U.S. scientists have developed what they say is the first integrated nanosystem capable of replicating the process of photosynthesis, a sort of “artificial forest” that could one day lead to the production of hydrogen that could be used to power fuel cells.
Composed of nanowire structures — including silicon (more…)

You can see lots of attention is focused towards alternative and renewable energy systems. This is due to the soaring energy costs and the need to decrease the climate change effects over earth. Though these solutions may seem complicated for the homeowners in their daily chores, however, the fact is that they are now becoming more accessible to common man. (more…)

A semiconductor is a material with electrical conductivity intermediate in magnitude between that of a conductor and an insulator. Semiconductor materials are the foundation of modern electronics, including radio, computers, telephones, and many other devices. Such devices include transistors and digital and analog integrated circuits. Transition metal oxides also (more…)

Earlier this year, the California Air Resources Board (CARB) completely revamped its passenger vehicle emissions control regulations. The new Advanced Clean Cars program, which covers model years 2017–2025, combines several regulatory schemes into the new program: the Low Emission Vehicle (LEV) program, which governs tailpipe (more…)

While we are seeing many exciting new developments every day in green technologies, one of the interesting features of the current cleantech boom is its reliance on mature technologies such as solar PV and wind, which went through prior periods of innovation in the 1970s and ’80s.
Thus, many of the green technologies in use today are (more…)
