Well, fusor.net got hacked. It was
working last night. Found the message "HACKED BY ION !!! Mad_Skater was
here !". Hope the site was backed up or mirrored somewhere. If not,
it will be a tremendous loss.
I found that the WayBack machine does have a
2002 copy. The magic of having computers with too much time and disk
space. Looking back though, there’s a lot of messages, interesting
information and pictures of amateur fusors and other such stuff missing.
I really hope they had backups.
vacation, and the holidays are approaching fast. Huntington is targeting
January 31st for the chamber… I read a
Farnsworth patent. I need to plot the cross section for D-D reactions,
as well as some of the others. Farnsworth was nice enough to supply
figure 10 from the patent above.
second Bussard patent again. I understand his point now about using
the grid as the ion guns. He’s using the electrons oscillating between the
grids to ionize the fusion fuel, just like all the glow discharge fusors that
have been built. I’m reading it again to gel my ideas on it.
So I had this
really wacky thought. There’s this really off the wall thing called the
Biefeld-Brown effect. As you can see by doing a google search, there’s
a lot of weird science associated with this stuff. What is cool is that at
least it’s been reproduced. Regardless of whether the effect works in a
vacuum (I’d demand a lot of reproductions, as this would be a very cool effect),
it does seem to be a very nice accelerator for air (nitrogen) and other gases.
NASA has a
patent out on what essentially amounts to an ion thruster using the effect.
So I wonder if the Biefeld-Brown effect can be used to advantage in the fusor?
I’ve always wanted to do field analysis of some of the figures from the patents
T Townsend Brown. Just using the simple version like that on the
left should be sufficient. I wonder
if just simply extending the cathode grid to a shell, much like the butterfly
cage, might actually form a very efficient spherically focused ion accelerator.
Bussard is firm on the point that you must not have any magnetic fields in the
grids, as this would add transverse motion to the beams. Thus, there would
actually have to be four layers here, two to a grid. The layers have the
current flowing in opposite direction, so the magnetic fields cancel.
Which is kind of odd at first glance, because in the same breath as he’s
saying this, he’s also saying that the system using the magnetic polyhedral cage
with ion and electron injection works as well for the
inertial collisional compression effect. The reason this still works
is because the ions are being created outside of the cage field, and are
accelerated through the faces or vertices of the magnetic cage. In the
vertex case, each one is a magnetic quadrupole and is thus a very nice beam
guide. In the case of the faces the beams are perpendicular to the field
lines, so the ions will orbit the field lines, spiraling down. I’m going
to have to model this with something like EGun or some other field ray tracing
program. It’d be very interesting to model. I’m pretty sure there
shouldn’t be much transverse motion induced, but what the heck do I know
