Simple Heat Engine
« on: May 16, 2005, 07:48:33 PM »
I work alone in my office and sometimes it gets pretty quiet. I passed by a Magic Shop a few weeks ago and bought a Dippy Bird, a.k.a. Drinking Bird, to keep me company (yeah, I'm wierd). I was prompted to search the net to see of anyone was trying to harness these things. Lo and behold, some university in California has already developed 6 foot dippy birds (yeah, they're wierd too) and there is a field full of these things dipping into a stream. I't quite a sight to see.

With all that mass swinging back and forth it seems that a shaft/ratchet assembly could be used to turn a flywheel, which in turn might turn a PM generator. I checked with the hardware stores and it looks like one could use a couple of propane tanks and some one inch pipe to make a workable dippy bird. The local chemical supply has methlene chloride for about $12.00/gal.

It could work, no?

Yes, I suppose I could, but from what I've seen of the Minto wheel it would be a bit more complex in construction and the fluid transfer appears to be slower. Please excuse me if I don't see the full picture, but
I believe I could make the heat exchange more efficient on the dippy bird through evaporative cooling on the head and heat the base at the same time by painting it black (better yet forrest green, which is more solar efficient).

Have you built an efficient Minto wheel? I'd love to see your results, as I'm always looking for a better way.

Can you elaborate on the forest green color instead of black, interesting.

Are you talking about something along the lines of this?  (links updated - 9-3-07)

These use propane gas and water on a teeter totter arrangement.... radiator type containers are alternatly heated by small tank of solar heated water pumped by a small pump connected close to the pivot point.. see this link for some different versions
