Bussard’s Polywell, Part 1 (of 2): the greatest invention of all time?

Being deeply interested in the future of Energy, and knowing the interesting fact that what 99% of the public hears is pure baloney, I’m always on the lookout for the latest and greatest new energy technology and this one is worth mentioning. A little background for you non-physics-types first …
E=mc^2 means that if you could convert matter directly to energy then you could get an unbelievable amount of energy from it. One ton (think of a dump truck full of dirt) could power 3 Million homes for a year. Or it can provide the propulsion for space tourists to cheaply fly around the solar system and beyond, and at much higher speeds than is currently possible. The Polywell EIF (Inertial-Electrodynamic Fusion) device, invented by Robert Bussard who was a former Assistant Director to the U.S. Atomic Energy Commission (AEC), can do just that. It seems to have overcome all the major obstacles facing fusion.
The Polywell Fusion Reactor
That said, don’t confuse a fusion (fuse atoms together) reactor with a fission (tears atoms apart) reactor. Dangerous and dirty fission is what all contemporary nuclear reactors use. If it helps you, think “fusion = fuse together, or build up”, “fission = tear apart, destroy”. Fusion is usually good because it produces safe byproducts, fission is bad because it usually produces dangerous byproducts and requires radioactive fuel.
The proposed fusion-based energy generator uses Boron of which we have enough reserves to last us 200,000 years (at our current energy usage). What’s more is that the only byproduct is unreactive (safe) helium which harmlessly vents naturally to space, where it is the 2nd most abundant element in the universe. Sounds better than Solar CSP of which I’m such a huge fan. Time will tell. I’m convinced Einstein would love it Why not us?
