Anyone know if it even possible to hook a small scale hydro generator into an boiler pump? just thinking if it would generate enough electricity to power itself, with battery backup. Might also look into solar.
 
kind of sounds like a perpetual motion machine....

From what it sounds like, you are wondering if the flow by convection out of the boiler could create enough electricity to run a pump?

I guess Im not sure how thats possible, or why you would need it. If you had a system that could flow enough water without a pump (a gravity system, that used to be used all the time), you wouldnt need to generate the electricity at all.

Can you give a little more info as to what you are thinking?
 
Using convection to generate power, then using that power to run a pump, would produce less flow than the convection flow. The pump would be an impediment.

Power generation is not 100% efficient, then running a pump is not 100% efficient.
 
If you're talking about hydro off of the boiler then what they said.

I did read somewhere that I thought was respectable about using off the shelf circulators for water turbines in a "pressure recovery" setup, that was talking about multiple horsepower three phase pumps though.
 
After thinking about it and talking with a few people that do solar, it wouldnt be a very efficient setup, as mentioned flow restrictions and possibly burning up a pump. Ohhh well maybe a solar panel.
 
Law of Energy Conservation- energy cannot be created, or lost, only change forms. Electricity is converted to mechanical force, which would then be converted back to electricity. But some of the energy is converted to friction of the fluid flowing, and the pump shaft friction.
A solar panels just convert forms of energy, It just happens to be that the sun provides "free" energy for you to convert to electricity, or concentrate and use for heating.
