Hydrogen is lightweight and efficient as a fuel. When it burns, you get water as the exhaust, and the fuel cell technology that burns the gas is well developed. The major hang-up has been how to produce hydrogen without needing lots of fossil-derived energy.
Apparently, the way to cheap hydrogen is through aluminum. Purdue researchers earlier this year announced they'd found a way to use aluminum to get hydrogen from water. Today a Chinese ceramicist who did graduate work in Portugal says there's an even simpler way to derive hydrogen. This process uses powdered aluminum at room temperature, … Read more
