there is no such thing as critical mass when it comes to fusion, the admission of many authors of posts on this thread to know nothing about fusion
should be a big sign of how futile the suggestions are.
You must first understand what you are doing before you figure out how you are going to do it.
Fusion is an additive process, you simply need to be able to overcome the coulomb repulsion between two nucli/protons, such that the strong force
takes over and you create a new nucleus with the two things you squeezed together.
it is simple sounding, but the reality is that even thanks to the reduction in temperature thanks to QM tunnelling effects, we need to create a plasma
of high energy particles and contain those particles in a very small space. It will produce energy in the form of MeV gammas, which we need to absorb
in order to get any energy out.
The only so called critical mass is just the amount of fusion you can sustain in a controlled manner, allowing you to pass the break even point.
The toroidal design allows for simple magnetic confinement, and energy collection. Many of the laser+drop methods are one shot... drop pellet in, boom
- gone in a split second. In a toroidal confined plasma you can sustain the generator for avery long time.
Also, you know what would happen if you lost confinement?
Nothing... because the confinement is what is causing the fusion process, loose confinement and fusion instantly stops. Most you would do is burn out
a bit of your inside surface. It would be very very safe in comparison to a fission reactor.
The whole ring of smoke idea? well what you are saying in reality is that we need to make an atom smasher, smack two bunches of particles into each
other and have them fuse... we already built those, the amount of particles you can get to collide together is quite small... even in the LHC, the
amount of collisions per bunch is typically a handfull at most for each event they look at in the detector. and the bunch sizes? well they are made up
of something like 10^12 or so protons per bunch.... (something of that order, i need to look it up) so what you would actually do is make your reactor
extremely radioactive due to nuclear spallation and get out not all that much power.... oh and by the way... accelerating and confining large large
large bunches of particles is a big problem... oh yes, see above.
