Why would a man construct a dining-room table that can cruise down a racetrack at 130 miles an hour and shoot flames into the air? Sheer competitiveness. A record for the world’s fastest furniture existed—92 mph on a sofa—and Perry Watkins wanted to beat it.
In what sounds like the most over-engineered toilet tech ever, Stanford engineers are using rocket science to clean up sewage.
It's actually simpler than it sounds -- the scientists are developing a system that exploits sewage-loving bacteria to produce nitrous oxide, which can be used up by a rocket thruster. The nitrous-powered rocket's only byproduct is hot, pure air.
Despite all the talk about carbon capture, carbon footprints and carbon trading, carbon dioxide only causes nine to 26 percent of the greenhouse effect. That means that the majority of warming results from gases with a much lower media profile than the paparazzi-trailed starlet of global warming, CO2. In honor of last weeks' report in the Journal of Geophysical Research, which identified a brand new greenhouse gas, PopSci.com counts down the gases that bring us bikini weather in Antarctica and beachfront property in Montana.
