The devices, long thought to be exclusive to multimillion dollar research labs, are being built by a community of nonspecialists.

This week, the BBC published an interesting article on a community of amateur scientists building their own nuclear fusion reactors. is an online community of nuclear fusion enthusiasts, many of whom have actually created reactors at their own expense. Building fusion reactors is legal, as a fusion reaction doesn’t require dangerous nuclear materials like uranium or plutonium. The community has DIY guides and discussion forums for these amateur science junkies who juggle their passion for building reactors with their day jobs. The challenge they, and for that matter, scientists and research labs across the world, face currently is that nuclear fusion reactors still use more energy to run than they produce.
