Thanks for taking the time to think about it - very helpful comments. Will check FenBen out and stick some references in as I find them again.

Do you have a better resource or recommendations? I'd be happy to remove this from the internet. I feel that most other articles on the topic would be severely self-censored because of the small amount of research and the risk you mention, or just not interested in low-cost alternative treatments without a "medical" stamp on it. Research and reporting on low-cost treatment methods is probably underfunded.

Webgl + js. same approach as https://ciechanow.ski/

I worked on this and host it on my site as well where it's not parceled up into bits and pieces. Have to thank Bartosz Ciechanowski. Learned a lot from his code and approach.

not when it's more expensive than diesel. Must find the balance.

nah you can just create little holes in the sphere to illuminate the planets. negligible power loss. Earth and all the planets live on the sun's crumbs, no the (crumbs of the cumbs)^12

I like the railgun analogy. I think you can stock up on other fusion cost arguments through my article, Engineering and Economic Challenges of Fusion: https://lvenneri.com/blog/ConFusion

My own partisan comments on the pebble bed class of reactors (https://lvenneri.com/blog/pebble-bed-nukegumball) for those interested in a deeper yet still qualitative comparison of pebble beds and prismatic cores - the main types high temperature reactor. Long story short : pebbles offer significant disadvantages compared to prismatic geometries, summarized by this donald duck clip: https://youtu.be/shvwSBGDmE0.

They will have two types of reactors. First, large centralized reactors for DD fusion to make He3. These will be more expensive and challenging because of the neutron bombardment. The other for D-He3 fusion which will be for smaller sites and produces less neutron damage.

They will make the He-3 using D-D fusion reactors (which is not aneutronic) and waiting for collected tritium to decay into He-3 (12 years). In each shot, they have to remove the he3 and T to prevent them from reacting.

In the D-he3 reactors, they cannot fully prevent the side reactions of DD and DT. But they can minimize them by controlling the mixture of he3 and D in each shot and constantly extracting the T byproduct of D-he3. Basically, they will have high ratio of he3 to D ions so that all the D ions are likely to be used in D-he3 reactions. Removing and collecting the T in each shot removes the opportunity for D-T. It will probably work to an extent, but there will still be side reactions. The overall neutronicity will likely be in the 2-5 range in the D-He3 reactors.
