Looking to get in a hybrid for cheap? Used Toyota Prius 1.5 HSD 2004-2009 Review

Green Car Congress

On the way there, I made a pit stop at a gas station to buy a bottle of champagne as a gift, hoping to start out a conversation with a stranger on the right foot. One of our 2006 Prius’ pack needed servicing and it only cost a few hundred dollars to fix 7 modules and change the bus bars connecting the modules by a hybrid shop.

Startup Siluria Technologies developing novel bio-templated catalysts for economic direct conversion of methane to ethylene; potential for transportation fuels

Green Car Congress

The oxidative coupling of methane converts methane into ethane and ethylene (C 2 hydrocarbons). In a presentation at the Spring 2006 AIChE national meeting, researchers from Mesoscopic Devices noted that today’s catalysts exhibit either high selectivity (>70%) coupled with low conversion ( 75%) with low selectivity.

A Skeptic’s Take on Beaming Power to Earth from Space

Cars That Think

Each megasat could then convert gigawatts of power into a microwave beam aimed precisely at a big field of receiving antennas on Earth. These rectennas would then convert the signal to usable DC electricity. In that respect, beamed power from space is like nuclear fusion, except at least 25 years behind.
