SwiftFuel Alternative To Alternative Fuels 725

TheDawgLives writes "PBS has an article by Bob Cringely about the best route to end our dependence on oil and reduce our greenhouse gas emissions. Instead of replacing all our expensive cars with even more expensive hybrids or electric cars, his suggestion is to use a cheap drop-in replacement for gasoline called Swift Fuel. It is derived from Ethanol, but doesn't require any modification to older cars to prevent corrosion. It can be mixed with gasoline in any amount and can even be distributed using the same network as gasoline, including being pumped in the same pipes and shipped in the same trucks. It is truly a drop-in replacement for gas, and it is real. It is being tested by the FAA for certification in propeller aircraft. It also happens to be about $2 a gallon cheaper than gasoline."

Pentagon Wants Kill Switch For Planes 548

mytrip writes "The Pentagon's non-lethal weapons division is looking for technologies that could 'disable' aircraft, before they can take off from a runway — or block the planes from flying over a given city or stretch of land. The Directorate's program managers don't mention how engineers might pull off such a kill switch. But, however it's done, they'd like to have a similar system for boats, as well. They're looking for a device that can, from 100 meters away, 'safely stop or significantly impede the movement' of vessels up to 40 feet long, with 'minimal collateral damage.'"

Real Users find the one combination of bizarre input values that shuts down the system for days.
