As spaceborne energy-harvesting schemes go, this one seems faintly possible — an array of curved mirrors directing sunlight toward solar cells, their energy production microwaved down to Earth. It’s so realistic, actually, that NASA is providing funding for a proof-of-concept study.

The One Laptop Per Child initiative has had its share of development hiccups. The project hasn't gotten the notebooks down to goal of $100 per machine, and a few recent bugs have delayed the recently proposed Give One Get One plan, in which customers in developed countries buy one of the laptops for themselves, and another for someone in need.
But down at the grassroots level, the project seems to be taking hold. In India, for example, the group is developing a cow-powered system in an area short on sunlight, wind and other good renewable energy sources. Cattle would pull on a series of belts and pulleys, activating a dynamo that re-charges spent laptops. Which is exactly how I use my cows.—Gregory Mone

President Bush assured Americans in January's State of the Union address that with his $1.7 billion five-year hydrogen initiative, "America can lead the world in developing clean, hydrogen-powered automobiles." In April, however, while U.S. automakers tinkered with prototypes, Iceland opened the world's first retail hydrogen-fuel pumps in a converted Shell station in Reykjavik.
