I'd forgotten about Helion. They also claim low neutron production and direct electricity conversion.
ohwilleke's post made a very good economic argument. No reactor-weakening neutrons and direct electricity production are what make economic sense to me.
Helion claims $0.04/kWHr...
Yes, but it can also mean other's aren't attempting it as it's more difficult. I mentioned in my initial post that boron fusion is less efficient.
I think everyone realizes controlled fusion is difficult and in the future, but my question remains. Is anyone aware of another project that...
Yes, no fusion has achieved net energy gain. However, Tri Alpha seems quite unique by the type of fuel they use and their generating technique. To my knowledge, all others intend to generate neutrons and use a steam boiler.
Is that correct?
Fusion reactor development has long interested me. From what little I know, Tri Alpha is unique as they plan to fuse boron and won't use their reactor as a glorified steam boiler.
By fusing boron I believe they avoid producing neutrons. The downside is that requires a higher temperature than...
I do not mean to be rude and I'm sincerely not trying to be snarky. But I just don't know how I can be more clear. You're making this too complicated.
I initually used the nut example as I thought it clear. I still do. I then explained it's a tooth that engages a bicycle chain as I feared I...
Now we're talking. An interrupted screw is worth looking into.
To answer the question, no, the nut has no resistance while rotating. I use the term nut for illustration. The actual application is a tooth which rotates 90 degrees on and off. At 0 degrees rotation (off) it's not engaged while...
Indeed, what I described is basically a bayonet fitting. It just seems to me a threaded union without locking would be better. Again, I have no idea how to accomplish that. I was hoping there may be some obscure thread type unknown to me.
I'm confused. What's unique about the threads of a wingnut? Are you suggesting I use the "wings" against a stop?
I'm using a pin on the axle and a slot in the nut now.
Is it possible to use a thread to stop the rotation of a nut without locking the nut? For instance, I want a nut to rotate 90 degrees only. That's the easy part. But I want to be able to reverse the rotation without having to apply force to break the nut.
In other words, I want to nut to...
