Possible breakthrough in energy source research!

I assume you need to put a small amount of energy in to get them together though, don't you? Just much smaller than 28 MeV?

Yeah. The hill is surrounded by a bump which you have to get over. At long rangs, the coulomb repulsion between two deuterium nuclei is much larger than the attractive nuclear forces. So they don't want to hang out. But if you give them enough of a push they might be able to get close enough to each other to get past that. At close distances they will be sucked into each other (when the attractive nuclear forces get much stronger proportional to the coulomb force). That's why fusion only happens at high temperatures (actually, it happens really really slowly at low temperatures too, but unless you've got a billion years to wait around, that would suck)

How does magnetism affect electricity?

We must retitle this thread as:

Physics 101 by KrazyHorse and CIE.
or
How to transform a noobs into a physicist in one thread by KH and Cie.

They are basically the same thing... they are related through Maxwell's equations.

agreed, interestin stuff so far

so it is possible to use magnets to blast it in a particular direction?

Not being a physicist, I think that's basically how an ion engine works: Using a magnetic field to control a volume of charged plasma and eject a stream of it out the back end. Didn't they do that in recent years with a space probe?

Good stuff

Re: ion drive. IIRC, a new space probe with ion drives will be launched soon. This year, I think.

Except we haven't been able to find magnetic monoples.

What is plasma?

Plasma: (wikipedia)
Plasma is an ionized gas, and is usually considered to be a distinct phase of matter. "Ionized" in this case means that at least one electron has been dissociated from a significant fraction of the molecules. The free electric charges make the plasma electrically conductive so that it couples strongly to electromagnetic fields. This fourth state of matter was first identified by Sir William Crookes in 1879 and dubbed "plasma" by Irving Langmuir in 1928, because it reminded him of a blood plasma [3]
What a beautiful picture! :y:

Doesn't mean that electricity and magnetism aren't the same thing (just different manifestations of the same phenomenon).

Monopoles are only necessary to make the field equations governing them exactly symmetric. Even if the equations governing the fields were not at all similar they would still be part of a unified phenomenon.

Plasmas are basically soups of ionized gases and free electrons floating around. Since the ionization energy of most materials hovers somewhere north of 5 eV (corresponding to a temperature of ~50 000 K = 90 000 F) you can see why plasmas are not an everyday occurrence...

That's why plasma TV eats so much energy.

This troll is hilarious!

KH, I guess they don't know what is going on, they already said that, but if something that can release temperature yet unseen and several orders of magnitude higher than last record, that something is a discovery itself.
And I really think the scientists at the site are more competent than you, and they most probably have not overseen the shield energy you mention and many other possible sources of whom you probably can't even imagine.
