student with a short question about fair project.. please.


I was directed to this site by Doctor J. Snyder from CalTech.  He said you might help.

I don't know much electronics yet, but i can assure you, as soon as I can, I'm going to pick a college that offers a degree in alternative energy systems.


You're busy, so I'll be quick. . . 

I'm designing, on paper for now, a science project that  consists of a controlled compost pile covered by a blanket of thermo-electric generators, all connected in series and trickle charging a bank of batteries.

A well-tended compost pile can generate heat up to 150 degrees.  My own, has maintained a steady average internal temperature of 90 degrees for 3 months, while the air temperature was under 32 degrees (F)

See, we live in an area with very little wind or sun, but lots of cold.  And all my neighbors have compost piles.  I KNOW compost.  

I've read lots about the great efficiency of thermo-electrics in space, but I'm thinking of a more down-to-earth function, especially for third world people.  

Also, do you know where I can find a supplier for these thermo-electric wafers, or is it possible to build a rough copy of one myself ?  My dad is a good mechanic, and I’m learning electronics, but we don’t have a lot of money, and definitely no money to waste.
I would like you to tell me if you think I’m wasting my time.  I’ll keep researching the subject of course, perhaps using a Stirling engine instead.  But I would very much appreciate your personal opinions.


Thank you, sirs and madams. I will let you know how it turns out.
