What was once a dirty word in nuclear physics is garnering renewed attention from the world's most powerful military.
Today, the U.S. House of Representatives committee on armed services is set to be presented with a bill outlining the potential of cold fusion — a technology that used to be the poster child for scientific hoaxes.
What is cold fusion?
Cold fusion is based on the premise that you can, at Earth-like temperatures, force the nuclei of two hydrogen atoms to fuse to make an atom of a larger size and, more importantly, create a bucketful of energy in the process. Nuclear fusion happens all the time in the sun, but that's millions of degrees hotter than anything we would see on Earth.
