What are disadvantages of nuclear fusion?

[Aghanim]

Funny, I searched that entire paper for "department", "funding", and "defence", and nadda. I must conclude you are making that up and citing an irrelevant document to lend superficial support to your statement. In fact their own website states clearly that they are a "charitable research and development organization". DoD contracts don't fall under "charity" by any stretch of the imagination.

"Everyone thinks" isn't an argument for anything.

In fact, Focus Fusion openly admits their project may fail. That's why they can't give shares in their company to just anyone.

And a scientific review concluded exactly the opposite of what you are saying.

I was wrong with the DPF, yes not everyone, but some people. Don't get me wrong, I support DPF. But with so many 'free' energy source scam, like cold fusion or overunity machine, people are getting more skeptical. Unfortunately, this makes them doesn't want to pay for DPF, which has proven science. For polywell however:

This work was performed under Contract N68936-09-

0125 awarded by the United States Department of De-

fense.

Page 8. Its Defense, not defence

And as far as I know contract = funding, although I might be wrong

Searching for that contract number returns this:

It seems that the Navy pay $17,554,409 to EMC2 for that research

This makes me wonder. US have the highest military budget. Most, of not all, of their fusion projects are related to military somehow, like NIF and Z machine are nuclear bomb simulators. But why do they spend most of their fusion money on tokamak? Or they isn't?

dpf seems like a scam because of all the green folk supporting it. i know that most of the articles ive read on it seem to prattle on about the environment this and global warming that, rather than discussing the technology in any detail. this is obviously neccisary to aid in the crowd funding, but it also has the side effect of making it look like a scam since there are some elements in the green movement that are totally nuts. however what ive seen from the tech side looks interesting. especially the part about exploiting the natural characteristics of plasmas, rather than fight them with magnetic fields.

Then one should cite sources that actually support the statement instead of just asserting it.

well this was in

, which i assume anyone who gives a damn about fusion has seen (and i post that link a lot on this board), its well worth the watch. its rather amusing, he talks about how the dod loves to defund energy projects, then he talks about how the navy wants fusion reactors on all its ships. i especially love all the tokamak bashing.

no source on the weaponry, but its not like those kinds of systems are scifi anymore, and having a reactor on board makes those weapon systems possible to integrate on smaller vessels without fission reactors. since the polywell is a small reactor, retrofitting them into almost anything the navy has should be possible.

Then as I said, cite clearly. I admit I was wrong; I didn't know they were still being funded by the DoD. In fact I'm amazed because Bussard's talk (which I had already watched) went into detail about how the DoE wouldn't fund them and the project would get killed quickly if the Navy funded them so much that it appeared in Congress, and how they had stopped being funded by the Navy entirely.

but it also has the side effect of making it look like a scam since there are some elements in the green movement that are totally nuts.

Like these people?

Bussard's been dead for a fair number of years, the company's out of his control. Dr. Nebel was in charge when they got Naval funding. Also, Greenpeace are full-blown-sandwich-board-doomsday-prophet nuts. They once tried to convince me global warming was a thing. Not bad, you think? It was completely redundant, this was in England at a hippy music festival. Everyone already knows.
