Subject: [microhydro] have shaft-torque; need heatflow, not electricity.
I don't want electricity. I want heatpower.
A microhydro shaft is delivering kinetic energy; and heat is kinetic
energy. I'll be darned if I'm going to suffer conversion
inefficiencies with an electrical intermediary.
Most facile way to turn shaftpower into heat?
Dear Alanh,
As a student of technology, I know of a devise that was used to start fire
by compressing air in a tube. I forget the name it (I think they are called
fire hammers?). But with that same principle, you could construct a cylinder
that would compress the air , create heat and when the cylinder came back up it
would push I new air and push out the hot air.
Of course since this has never been done the way we are talking about, I
recommend just getting an AC generator, and running it into a heater. The
frequency would not matter since all the energy is just being turned to heat.
This is a simpler, off the shelf, way to go. The heater would have all those
safety features also.
