A racing team led by 66-year-old Ed Shadle is gunning for the world land speed record of 763 miles per hour--their goal is to break the 800 mark. Shadle has spent a decade and $150,000 getting ready, and transforming an old jet into his potentially record-smashing ride, the North American Eagle. The car boasts 42,000 horsepower, and will supposedly do 0 to 800 in just 20 seconds. And it's entirely green, running on solar . . . no, just kidding.
