Guy who works on Boston's Big Dig project is appalled at the wasted materials. So he collects stuff that looks good, hauls it away himself, and uses it all to build this house.

Turn your bicycle into a moped with revopower

The good folks at RevoPower claim they’re re-inventing the wheel. And, let me tell you, I’m wanting to believe them. Here’s the deal. You take your current bicycle (be it a mountain bike, a cruiser or a commuter bike), you remove the front wheel, and replace it with RevoPower’s. A little wiring here and there, nothing too hard, and you’re set. Then, you go out biking, as usual. But, say you’re growing tired, or you hit a slope and you’re just lazy… well, press a button, and the integrated commercial grade, 23cc two-stroke engine will kick in. You get 1.1 HP or 0.8 KW power output with a maximum rpm 7500 to help you along the way. On a flat surface, the engine will even take you up to speeds of 20mph, with a merciful 200mpg.
Nothing too amazing here, except click through and look at the picture. It's really slick how integrated it is with the wheel. Seems like it would be really easy to switch front wheels back and forth between this, and your traditional bike wheel.

"Theoretically, Stirling dish farms with a total area of 100 miles square could replace all the fossil fuels now burned to generate electricity in the entire U.S. What happens in the California desert over the next few years could determine whether thermal solar power can help end the dominance of fossil fuels."

I haven't read it yet, so I'm not sure if it confirms or denies my skeptical take on most alternate energy sources, but Popular Mechanics has a new article that chrunches the numbers. Seems like the right place to start.

Students from the Danish college of technology (DTU) have develeped a new and innovative fuelsystem which eleminates the loss of hydrogen in a fuel cell.

By eleminating the loss of hydrogen in the fuel cells, the Danish students have made hydrogen power "cost efficient" and have layed a major piece in the hydrogen engine puzzle.

The new fuel system was developed while working on the new hydrogen car "DTU Dynamo". Last year the car set a new world record by driving 15 miles on 0,35 ounces of hydrogen. This equals to the 450 miles per gallon of gas.
This new invention has already been patented, and a new development is said to be underway.
