I am a big fan of the Back to the Future movie series, having seen the first one in a theater on opening night. One of my favorite scenes in when Doc comes back to get Marty at the end of the first movie and goes rummaging for trash to put into his "Mr Fusion" appliance. This trash into energy thing always seemed to me like a cool idea.
The US Army commissioned this project at Purdue University. The result is this device which takes trash of all sorts and reduces it, in the process, producing 90% more energy than it consumes. The resulting energy is used to power a generator. That sounds a bit like old Doc Brown's Mr Fusion to me. 2015 here we come! Now, who is working on the Hover Board?
