Fusion - May be sooner than thought

Fusion has been the great hope for energy that was just around the corner. An article about a VC investing in Fusion saying it may come sooner than thought. Fusion Power in the Next Five Years!? Fusion does not have all the radioactive issues that Fission does.

The problem is Fusion has always been 5 years away, for a long time. Fission (regular nuclear power) is getting more attention since you don't have green house issues. The challenge is where do you store all the Nuclear waste that will stay radioactive for a couple of thousand years. Yucca Mountain nuclear waste repository in Nevada has been in limbo for a while.

MHD

The method of generative electricity is still heat, that generates steam to turn turbines for generating electricity.
Magnetohydrodynamics seems like such a better process, but I have not heard anything about it for years. I worked for a firm in college that was doing experiments with Magnetohydrodynamics , till the Department of Energy stopped funding. Basically Magnetohydrodynamics is a plasma that electricity can be pulled from directly. For all a Magnetohydrodynamic generater is doing is disrupting a magnetic field through a plasma that results in Electricity. There was some experimentation with burning coal at high temperatures for the plasma, but that seems to have stopped in the US. Nice history I just found of MHD
