Taking another look at methanol as an alternative transportation fuel for the US

Green Car Congress

A recent white paper by Leslie Bromberg of MIT’s Plasma Science and Fusion Center and Wai K. In comparison, they noted, the technology for bio-chemical ethanol production from cellulosic biomass is not sufficiently developed yet. The toxicity (mortality) is comparable to or better than gasoline. It is a safe fuel.

Ford E85 Direct Injection Boosting Study: A Less Expensive Alternative to Diesel

Green Car Congress

Proposed by John Heywood and colleagues at MIT in 2005, the basic premise of E85 boosting is that ethanol (or other lower alcohols) suppresses knock due to the large evaporative cooling effect it has on the air-fuel mixture when injected directly into the cylinder, supplemented by ethanol’s inherent high octane number. Earlier post.)

GM Says Chevrolet Volt Won't 'Pay the Rent' | Autopia from Wired.com

Tony Karrer Delicious EVdriven

The four-door sedan will deliver 40 miles on a charge; a small gasoline engine will recharge the battery as it approaches depletion, extending its range by as much as 200 miles. That way you have a fair basis of comparison, you know, apples to apples and all that jazz. The car is expected to cost around $40,000. Thats short-sighted.
