So i wondered what's the hardest reaction in tpt. I think its prot prot fusion
prot+prot+velocity->hygn oxyg etc
or oxyg fusion
oxyg + oxyg + 9720+C + presure ->metl,neut,elec, etc.
either the diesel hydrogen reaction or getting antimatter from prot collisions
probably the smoke to co2 reaction with PTMN at -273.14C
It's AMTR creation via proton fusion. It's often only done with the powerful behemoths that are azure bombs.
Cold fusion is also a contender, not because it's difficult to create but because it's difficult to sustain.
I made a simple cold fusion reactor which has an efficiency of 36 sprk/hygn. uhh, whats ya point??? its kinda easy to sustain if you only put it in slowly, if you need more heat, get more seperate chambers rather than one big one.
Huh. When I build cold fusion reactors, I usually have to build subframe systems that dynamically cool them.
hang on a moment. is oxyg fusion the only way to get metl???
