Magnesium Power: White-Hot Energy

From The Economist:

New power sources could be made using magnesium.

STORING energy is one of the biggest obstacles to the widespread adoption of alternative sources of power. Batteries can be bulky and slow to charge. Hydrogen, which can be made electrolytically from water and used to power fuel cells, is difficult to handle. But there may be an alternative: magnesium. As school chemistry lessons show, metallic magnesium is highly reactive and stores a lot of energy. Even a small amount of magnesium ribbon burns in a flame with a satisfying white heat. Researchers are now devising ways to extract energy from magnesium in a more controlled fashion.
