- That is one of the secret things electrical engineers are taught :-)

- Nuclei have to be very close together to fuse, but if for example two hydrogen
- ions (p) approach each other, the positive electric charges will push them
- apart. If you "push" them hard enough, they will get close enough for the
- strong force to take over and they will fuse. (Some details left out for
- clarity). The natural repulsion of nuclei is the coulombic barrier.
