So you think you're DIYer than thou just because you make smoothies with a bike-powered blender and keep an apiary on your roof? Meet Mark Suppes. The dude built a homemade nuclear reactor in a Brooklyn warehouse. The only way you're going to top this is to grow your beard down to your waist and rig up a flux capacitor to your fixie.

By day, Suppes toils as a lowly web designer for Gucci. But at night he's Fusion Man, working to create the "holy grail" of energy production in a lab tucked away on a tree-lined street... across from residential apartments. But don't panic, as one fusion egghead tells BBC, "There is no chance of any kind of accident with fusion." And it's perfectly legal, too! "As long as they [private citizens] obtain that material [the components of the reactor] legally, they could do whatever they want," says Anne Stark at California's Lawrence Livermore National Laboratory.

In fact, Suppes is the 38th independent amateur physicist in the world to achieve nuclear fusion from a homemade reactor, according to Even a 15-year-old from Michigan has done it! Who knows, the next Manhattan Project could be going on right next door to your apartment. Again, no reason to be alarmed, but we're going to think twice before banging on the wall next time the neighbors are blasting Insane Clown Posse. [BBC]
