Rocket Fuel Powered Arm
Your current bionic arm just not cutting it? Tired of just rocking a pirate hook? Well a team at Vanderbilt University has developed a prosthetic arm that's powered by, that's right folks, rocket fuel! The team came up with the idea while trying to develop a system that functions with the same strength of a human arm.
Conventional prosthetic arms do not have the strength of their flesh-and-blood counterparts, the reason being the batteries. In order to lift comparable weights, a prosthetic arm would need a massive battery, too large for the prosthesis itself. So (project leader) Michael Goldfarb started thinking about other ways to power the artificial limbs, and came up with the idea of using the monopropellant rocket motor system that the space shuttle uses to maneuver in space.
It's pretty clear that this team lives by the same credo that I do. When trying to solve a problem, always consider some sort of projectile or explosive material in the final design. I mean, really, who needs a ding-dong anyways when you can have it torn or blown off by your bionic arm.
