Re: [TCML] Off grid, medium size, 12V battery powered TC

["Jonathan Peakall" <jpeakall@xxxxxxxxxxxx>]

Dave,

Hey now! That sounds like an idea. Folks used to use washing machine  motors 
for such things, and I have plenty of junk and I know where to get more. :)

I have a lawnmower motor hooked up to an alternator that I use for charging 
batteries, be easy enough to hook some other motor/generator/alternator. I 
have a 25 amp, 130V at 2500 rpm motor that might work, although I have been 
planning on building a wind turbine with it.

Hmmm, food for thought, thanks for the idea!

Jonathan
