The well-publicized failures of cold fusion may have tainted the field’s reputation, but physicists have been successfully joining nuclei with hot fusion since 1932. Today, research in hot fusion could lead to a clean energy source free from the drawbacks that dog fission power plants. Fusion power plants cannot melt down; they won’t produce long-lived, highly radioactive waste; and fusion fuel cannot be easily weaponized.
Former astronaut, Apollo moonwalker, geologist and former Senator Harrison Schmitt has a modest plan to solve the world’s energy problems. All we need is $15 billion over 15 years and some fusion reactors that have yet to be invented. And we’ll need a moon base.
In what the BBC is calling "a claim that is likely to be met with some scepticism," North Korea has announced that it has made huge strides toward developing thermonuclear power, going so far as to claim that the nation's scientists have built a "unique thermo-nuclear reaction device."
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
