It's nice to see people who normally make weapons design something less violent instead. Here we've got two examples:

1) Some five-star General's apparently been watching Back to the Future 3--like Doc, the US military has made a machine that turns garbage into fuel. The "Tactical Biorefinery" is...

...designed to ingest unfiltered garbage, from, say, a barracks or a mess hall. The garbage is ground up and organic food waste is separated out and fermented into ethanol while other waste, including plastics and cardboard, is heated and gasified into low-grade propane or methane in a parallel system. The resulting fuels are burned in a modified diesel engine to produce green electricity for our boys in green, err khaki.

2) "Don't tase me, bro." That University of Florida student would've loved the Net-2000 Shooting Rod, which ensconces you and your big heckling mouth in a spidery net, rather than sending 50,000 volts coursing through your body. Unfortunately we'll probably never see one of these deployed in denser cities like Manhattan, Seoul or Tokyo, unless you need to capture everyone in the subway car at once.
