I sure wish had some of that Princeton/PPPL funding over the last 50
years. $100 millions/year
over 50 years???? NSTX, ITER, GO Baby!!!!!
USA, Navy etc. are still pumping money into fusion. Must be getting
close in the objectives.
Boltzmann equation is fun... Tell me again why he commited suicide????
(He wasn't getting any
ATTABOYS/Respect for his work). DuPont inventor of nylon also took his
own life, I heard???
Nylon was an unplanned discovery???
USA government is making tritium now??? to renew/refresh tritium in
its hydrogen weapons.
So why not make extra tritium for use in fusion reactors... Early fusion
reactors will be big --- smaller
models/units may occur later on.
Perhaps we can deploy an early warning system to warn of
electromagnetic cascades and/or
hadron cascades bearing down on US Space crews. Gammas/XRays would arrive
at the speed of light. Electrons/hadrons would arrive somewhat later.
Extra time could be used
to turn on spacecraft protective magnetic field???? Don't know what the
time structure of the
arriving gammas/XRays/electrons/hadrons is... If much of the total dose
equivalent is from first
gammas/XRays, then the warning system wouldn't work. Oh well.
New fusion schemes like migma, mirror machines, laser inertial
fusion etc are still getting
Be good. Regards, Joseph R. (Joe) Preisig, PhD

I was a rad tech at Princeton's TFTR during the D-T test shots: they were
getting some really interesting results while I was there. Things like the
record temperature, enhanced reverse shear mode magnetic fields, six-Tesla
shots, and some interesting self-insulating of the plasma fields. We even
had a purification system to recover unburned tritium from the exhaust
gases. And this was in the 90's, using mostly 1970's technology. No
superconducting magnets, etc. I often wonder how much further we'd have gone with all
the new advances on the machine. But the funding wasn't there for the
There's little industrial funding going to fusion projects, because
industry is tied to the current fission technologies, which I personally feel are
less safe than fusion. We had "disruptions" (loss of magnetic containment)
on the system. It was no big deal, and there was no decay heat problem. I
worked in the TMI2 cleanup and in commercial nuclear power, so I am aware
of nuclear safety.
Yes, it's difficult to control essentially a miniature star in a jar...
but I have confidence in the folks at Princeton, UW-Madison, LANL, ITER and
other projects. The Manhattan Project took theory to practical in a short
period of time. I think we're up to it.
Lack of vision? It could cost us. Developing new technology to become
energy independent is a worthwhile project. If we want the economy to improve,
research will provide us the tools to do it. If fusion is to become viable,
we need to adequately fund tokamak, inertial confinement, and other fusion
test projects. Not just laugh at it. Consider it an investment in the
My humble opinion and not necessarily that of the management!
