IRL, a FPT fires pellets of lithium and deuterium (not deuterium oxide) out behind a large concave dish. It then fires powerful carbon dioxide laser to fuse the pellets, in effect a small thermonuke. I am attempting to recreate this, and everything works fine, except one thing: You cannot PCLN THDR and have it fall! If anyone has suggestions on fixing or finding an alternative to the problem, can you please comment.
