why not use a low temp stirling which will 85% run most of the time.
How cold is the winter floor again compared to the air?

why not get 20 of these in a row to power a 1kw generator which would be funny. (more likely 200-250w..)

its just a other way of geting em energy
If you guys want to build something fun then,
you guys can build a Ultra low power led , Powered by a dynamo, which is powered by a low temp stirling engine which is moveing it.
eh?
arrogance of ignorance aint bliss im afraid.
well the lantern sits on the ground doesnt it , and what is the temp difference of the cold floor to the air , these things can run of your HAND!
and it doesnt matter which way its moveing , just like if your hand was moveing it (maybe put something to get the stirling engine to power it,to Jerk it to get it started), why not a stirling powered radio :-D.
why hasnt anybody been un stupid enough to see in a str8 line?.
the idea here , is its a Cool powered engine when its just standing around or powered by the heat of yr hand.
A Little difference of 2 c will make it run ..(with prehaps enough grunt to power a 1w - 1.5w dynamo).
just needs to be kick started ;-).
or prehaps make a dynamo/stirling version for one of those head Light thingys eh?
you could make a fan out of it.
o_0 come on guys stop being so selfish, and think for others .
or money is your God?
(Why not give stuff that aint worth nothing,so it won't go to waste for example?)
a sitrling powered fan/Light/solar whatever, (about 30% of the bodys heat goes to the head, and the body has an avg of er if i can remember about 34 c avg..)
