Space Elevators
Just pure, geeky awesomeness.
In a major test of the concept, robotic machines powered by laser beams will try to climb a cable suspended from a helicopter hovering more than a half-mile (one kilometer) high.
I’m guessing jetpacks won’t be ready to go any time soon, but if I could ride on a laser-powered space elevator before I go, I’d be feeling pretty good about things.
