Apr 15th 2008 11:24AM An air scoop on the hood of a hybrid? To be nice, I like the wheels. The rest of it needs some work.

Mythbusters' mistakes in AC vs windows down episode {Autoblog Green}
Aug 29th 2007 12:47PM Bill (comment number 5) is exactly right. Vehicle coefficient of drag, CD, will influence the speed at which the efficiency crossover occurs. I have always used 45 to 50 mph as a rule of thumb for the crossover speed in my day to day driving to decide whether to have windows down or AC on. Of course in Dallas sometimes windows down just makes it hotter no matter what the speed.
Panasonic EV Energy expanding NiMH capacity by 50% {Autoblog Green}
Jul 16th 2007 7:52AM The new carbon fiber lead batteries from Firefly Energy have as much energy density, same recharge speed and temperature range as the NiMH at half the cost (or less). Look for a two tier system to emerge, cheaper electric cars using the Firefly technology and high end cars using one of the Lithium technologies. NiMH should fade out of the picture unless some significant breakthroughs develop.
Southwest US could get 250MW solar power plant {Autoblog Green}
Feb 27th 2007 7:49AM A group of MIT students re-produced the Mythbusters episode and were successful in starting the ship on fire using the same materials, just better approach.
Following up on three men and a tiny engine: MIT's efficient ethanol injection ICE {Autoblog Green}
Nov 3rd 2006 9:45AM I read about this a few months ago and even bookmarked the page from their website. These guys know of what they speak. The beauty of the idea is that no new technology is required. With some re-design of existing engines and using existing tooling the 20% - 30% efficiency improvement is achieved. Ford should jump on this and fast. Ford has the worst average corporate mpg figures of any major auto line in America. This would put them ahead by a mile if used throughout their line.

A poor argument for coal liquefaction {Autoblog Green}
Sep 7th 2006 11:02AM This coal to gas (not oil) process is perhaps better and does sequester about half the CO2. http://www.greatpointenergy.com/about.html
SuperGrid will deliver hydrogen, more electricity trough-out North America {Autoblog Green}
Jul 12th 2006 11:54AM I agree with Howard above. A much better approach is scattered small green technologies (small wind farms, photovoltaic when economical, etc.) rather than concentrated production locations. Scattered small production reduces the load at any one point and also gives multiple backup production rather than one central source or one backup supply. And the commplexities of transmitting liquid hydrogen in massive quantities are daunting and will take decades. Dozens of small wind farms could be built in a single year.
