Strictly speaking it doesn't decrease the heat dissipation, it
simply shifts most of it in time and location to the polymer
subunit synthesis stage. The only thing that decreases the
heat dissipation is coming up with very efficient reaction
steps. I'm not positive about this, but I think that may make
the reaction probability go down, so the synthesis rate would
be slower. So you can produce it "fast" if you can stand the
heat or produce it "slow" if you are short on energy.
