It's still wrong anyway.  You can't fuse 4 H (=4 protons) into a He (=2 protons
+ 2 neutrons); you need two deuteriums (an isotope of hydrogen with a proton
and a neutron) or an ordinary hydrogen and a Tritium (=proton + 2 neutrons).
You could also have some exotic reactions with 3 atoms, or perhaps involving
lithium.

I always assumed Trav refining plants were heavy hydrogen isotope extractors,
although why having too much ordinary hydrogen in the fuel should cause
misjumps is a mystery.

Unfortunately I don't have a molar weight for deuterium handy.
