Panasonic develops highly efficient artificial photosynthesis system with gallium nitride semiconductor for conversion of CO2 to formic acid

Green Car Congress

The reaction rate is completely proportional to the light power due to the low energy loss with the simple structure; in other words, the system can respond to focused light. Panasonic’s artificial photosynthesis system has a simple structure with highly efficient CO 2 conversion, which can utilize direct sunlight or focused light.

BIO Conference Highlights Emerging Range of Pathways to Drop-in Renewable Hydrocarbon Fuels

Green Car Congress

The following list of companies presenting their pathways to hydrocarbon fuels at the BIO conference is not exhaustive; indeed, other companies at the same conference could take their platforms, which they are currently targeting at the lower-volume, higher-value chemical molecule market, to produce higher-volume, lower value transportation fuels.

Gallium Nitride and Silicon Carbide Fight for Green Tech Domination

Cars That Think

Starting around 2001, the compound semiconductor gallium nitride fomented a revolution in lighting that has been, by some measures, the fastest technology shift in human history. Globally, lighting accounts for about 20 percent of electricity use and 6 percent of carbon dioxide emissions, according to the United Nations Environment Program.

Heidi On The Hot Seat

Creative Greenius

As if the climate plan goal wasn’t hard enough, Aten holds a position infused with local politics - so much so that after reading a first draft of the one-hour interview we had conducted on January 15, 2009, she asked me not to publish our conversation as recorded and transcribed. Street Lights and Traffic Signals. Vehicle Fleet.
