Methane or acetylene seem like good choices as carbon is inert but very messy in terms of vacuum as carbon holds onto everything. Black powder all over the place isn’t very appealing either.
carbon will conduct electricity…. just take a pencil and draw lines from any 2 points on your distributor cap and run your engine. it just won’t be the same. I am still excited to see decaborane or alternative boron fuel introduced.. science is fun.
since boron is used in glassware could it be formed into strands much like glass fiber? I have a boron fiber fishing rod so i believe the same concept could be implemented.
could a small hole be drilled in the center of the anode and wedge some boron filaments in it for a test with just hydrogen gas.
