Hi!
I wonder why it is so hard to make a fusion reaction last for more than a few seconds.
I have read a few elementary courses in Plasma Physics but do not remember so much.
What I do rememeber is that they said that whenever a fusion reaction starts within a Tokamak the plasma tends to approach the wall and when it does it of course cools off and that is when the fusion stops.
But do I remember correctly?
I mean, there are other ways to start a fusion reaction.
I am thinking of laser-beams. But the same time-problem seem to excist there.
I am very excited about the ITER-project which I think is about to start.
Reading some information about ITER says that they actually think the output energy will exceed the input energy to such an extent that they, if it wasn't a pure experimental site, could hook it up onto the elctrical grid.
Sounds amazing!
Hope they are right because there is quite much hydrogen here on the planet. Even if the type of hydrogen (Deuterium?) is very rare but yet available in our seas.
Further more, the only "exhaust" is harmless Helium.
