The nuclear fusion of two protons in stars releases 1.442 MeV, or about 2.3 × 10-13 J. In order to fuse, the two protons must get within 10-15 m of each other (about the radius of a proton). What is the change in electric potential when moving one proton from infinitely far away to within 10-15 m of another proton? How much energy is necessary to push the protons this close together? Your answer should show you why it is difficult to develop a self-sustaining fusion reactor.
