So you like that?How about this one then?
http://www.rotarystirlingengines.com/rotacola.htm, but wait it gets better...take a look at number
6, disregard the first part ...(balloons are
probably cheaper anyway)
Well anyway I think if you were to scale this
popcan thing up a little...like the size of a
10 speed bike rim and enough popcans about 36?
I think it would be capable of driving a small
generator...like big enough to charge cordless
drill packs??
seems like it would be a fun
project for someone?
