“Usually, with deuterium, to cause a fusion reaction it is necessary to supply energy of 107 K, or 1 keV per atom. With light hydrogen it is necessary to supply 1.5 × 107 K, for a reaction rate of 10 -31”
Well, DUH.
Heh.... I hear you :-)
Articles like this one are obviously meant for a scientifically educated audience, but there's often enough plain English in there for us laymen to grasp the most important points.
This one's encouraging.
