Stirling Engines

Here's something Jack's been having fun researching...the Stirling engine concept has been around for a long time.

This is a book he purchased recently entitled How I Built a 5 HP Stirling Engine.  He's been enjoying poring over it, so it's worth a mention (we don't get any $$...just including the link if anyone's interested, it's a little pricey).



 Here's a link to a youtube vid showing an animation of the Stirling engine configuration. If I understand it correctly, it operates from the expansion and contraction of gases (heated and cooled) to create a vacuum that operates a piston (maybe I didn't get that right, but I'm new to this) :)

Here are a couple more just for fun...Jack's intent on exploring different options for energy.

oh now we must meet someday! i love sterling engines. i have spent countless hours reading about them. the heat source can be anything you want including, wood fire, solar and even nuclear(their most prevalent use). i think that those little wood stove fans are very cool and beautiful. they sell them at lehmans.com. i love books like that. i'll have to put that on my wish list. maybe a birthday present from tabitha...

Karl, yes for sure we'll have to get together and try not to blow up the garage. That fan's pretty neat...thanks for the link :)
