Fusion Reactor from UCLA

The problem with fusion is that it takes so much energy to contain the radioactivity that it is not practical as a power source in spite of the powerful reaction. :-(

I was referring to tokomak reactors.  They have to contain the ionic particles with a magnetic field to prevent the thing from getting out of control.  It may not be radiation in the nuclear sense but it does have ions in its intermediate stages with helium being the final product.
