hypergolic

a. applied to rocket fuel which ignites spontaneously on contact with an
oxidizing agent.

From Atomica: From German Hypergol, a hypergolic fluid propellant : from hyper-, extreme (from Greek huper-; see hyper–) + Greek ergon, work
Pretty cool--getting double the use out of the "er" part. Hypergol sounds like it might be a brand name--do you know, wsieber? Wonder why they didn't call it Hypergon?

And what would they have done if it were hypo- -ergon?

hyper-, extreme ... + ergon, work

Have we just now coined a new noun, hypergon (= workaholic)?

And there was me thinking you were referring to a golliwog on speed ...
