You might learn something with this Stirling engine model

on December 2, 2012 12:00 pm

If you ever wanted to turn the heat from your cup of tea or coffee into piston power, I have just the gadget for you. It’s a Low Temperature Differential¬†Stirling engine model. Invented by Robert Stirling back in 1816, this engine produces power from temperature differences. You can place it on top of something warm or cold like a cup of tea, cup of ice, the hood of your car, computer, etc and it will spin. If you’re in to Steampunk type gizmos, this would be a fun addition to a collection, that will actually work. You can find complete models and kits on Amazon¬†at different prices ranges, or if you’d rather go completely DIY, check out this how-to article from MAKE magazine.

    This is cool! When I was a kid I wanted to build one of these and made drawings and plans to make it really big with a gigantic Fresnel len that could also be used to shoot down invading aircraft and power an underground city where people would live and commute inside vacuum tubes… I was eight then :)

    All engines act by exploiting a temperature difference. A Stirling engine is just an example of one particularly efficient design.

    Really want to see some one making power from one of these.
    Charge your mobile from your morning coffee.
