I'm thinking you could probably make a hybrid car based around a steam
engine. The question being why would you bother?


No, it wouldn't be practical. It would take ages to warm up and waste
loads of power.

Drifiting even further from my orginal topic: The above reminded me that
some years ago work was done on small flash-tube boilers which apparently
heated up within a few seconds and were very efficient. In general,
external combustion does have some advantages. However I can't recall who
did the work, now.

Maybe the heat from output valves could be used to generate steam to
generate electricity to help power the amplifier. Might improve the
efficiency and the lifespan of the amp. :-)

That said, the closest I've got to the this was water-cooling of 100 GHz
klystrons.


With or without goldfish?
