No chance of meltdown, but lots of radioactive waste. A lot of which is light elements unlike fission radioactive waste, more easily incorporated into living tissue. Plus, bonus, may lead to a way to make cheap nuclear weapons without uranium or plutonium!

To put the heat problem into a little perspective. Lightning which is a common and widespread natural occurrence as you know, is five times hotter than the sun.

OK, I would not stand inside a fusion reactor, any more than I would want to stand in front of a bolt of lightning, but I think that the first may be easier to avoid.

The Chinese are building an artificial sun reactor, spending a trillion dollars.

We are all ignorant in the vast unrealized knowledge. Scientists split the atom in the middle of Chicago. I still do not understand how they did that without obliteration America's major heartland megalopolis.
