From Popular Science comes this article about the development of a real-life jetpack, a technological fantasy for many of us.
Juan Lozano, a self-taught Mexican rocket scientist may someday become one of a handful of people in history to make an untethered flight with a rocket belt.
Believe it or not, he uses 90% hydrogen peroxide which expands to 5,000 times its size and converts to steam that will reach 1,300˚F, and thus provide the thrust to hoist him 30 feet into the air.
I'm glad to see someone working on this. I've wanted a jetpack all my life and, honestly, I thought we'd be farther along by now.
