FEV testing finds Transient Plasma ignition system increases fuel efficiency and decreases emissions

Green Car Congress

Data was collected with the stock ignition system with a representative ignition strategy, followed by comparison to a drop-in replacement with the TPS nanosecond pulsed power ignition system (coil and plug). The Toyota 2.5L engine was tested at FEV North America and results indicate improvements over the stock ignition system.

Heat Pumps—The Well-Tempered Future of A/Cs

Cars That Think

Heath has great job security: half of Phoenix residents are at risk of an emergency room visit or worse if their electricity fails during a future heat wave, according to a recent study. But to get the air conditioner’s compressor working in the first place, a faraway power plant had to produce a surge of electricity.

Harvard team finds large-scale US wind power would cause warming that would take roughly a century to offset

Green Car Congress

All large-scale energy systems have environmental impacts, and the ability to compare the impacts of renewable energy sources is an important step in planning a future without coal or gas power. Wind turbines generate electricity but also alter the atmospheric flow, explained first author Lee Miller. degrees Celsius.

Synbio company Intrexon and Dominion partner to commercialize bioconversion of natural gas to isobutanol in Marcellus and Utica Basins

Green Car Congress

Intrexon’s proprietary methanotroph bioconversion platform uses optimized microbial cell lines to convert natural gas into higher carbon compounds such as isobutanol and farnesene under ambient temperatures and pressures. Methanotrophic bacteria oxidize methane as their sole carbon source to support cellular metabolism and growth.
