To anybody that wants to try making a computer board using a carbon megaisomer for the CPU (If turing complete, it can be arrayed in such a way thst it can self-program) to make room temp superconductors out of hewting carbon to 4000 to 10000°K in an arc furnace to create isomer/allotrope with consisting of a billion or so carbon atoms and there you go! To make cool w/ liquid nitrogen using substrate, just shrink into computer board hand it to somebody you know in factory shop making computer processes.they'll give you the finished processor cpu chip, paying in cash. You can fit thousands or millions of qubits on these and can pick up a car sized object of this with one hand because it's also extremely lightweight (not to mentoon durable) as elemental carbon. You can fly a spaceship of this by manipulating EM fields, and it'll go off detected pulse using hand gestures for turn signals. They already use carbon nanotubes (CNTs) for computer processors.

Use polybutylene trash bins for storing liquid nitrogen in custom setup (or use supercapacitor charged laser w/flashlight converted into laser oscillator). Use space resistant plastic glass for substrates.
