My green house for fish

  • We are currently upgrading MFK. thanks! -neo
That minigen rocks!!! I'd have bought one now but they sold out!!!!
 
There we go, the last link londondragon posted has pumping windmills!
 
If you wanted to go down the pumping route, it should be possible to do away with the alternator and just weld the axel shaft to the drive shaft of your drill pump, but then youd need to mount it directly over one of your ponds...

Hows the heater you made working?
