Engineers prove 40 mpg can be made affordable

After being pummeled so long for ignoring fuel economy in favor of performance, some automakers deserve kudos for developing cars that coax more than 40 mpg on the highway from gasoline engines--not gasoline-electric hybrids but regular, internal-combustion gasoline engines.

General Motors, Ford, Hyundai, and Smart already are selling 40-mpg gasoline cars in the United States, and later this year Honda, Kia and Mazda plan to join the parade.

The timing couldn't be better. With gasoline prices rising, the result of political uncertainty in the Middle East, some Americans are eager to buy higher-mileage vehicles but cannot afford the higher … Read more

Methanol fuel cells the latest in portable power

A German company has introduced a "wearable" fuel cell that uses direct methanol fuel cell technology, doing away with the weighty mechanical components usually associated with generation of electrical power.

Based on an award-winning unipolar stack technology design, the Jenny 600S delivers 25 watts of power for up to 20 hours at a time, according to the company Smart Fuel Cell (SFC).

SFC fuel cells took top honors in the U.S. Department of Defense's Wearable Power Competition last October against stiff competition from a host of big-name competitors. But it's not the only game: companies … Read more

Cleantech Blog did an article on the problems with micro fuel cells last year, but we have never written much on the larger size methanol fuel cells that Smart Fuel Cell is developing. SFC is one of the longest running direct methanol fuel cell companies in Europe, but never has made much press in the US, despite the fact that the US is one of their largest … Read more
