This engine runs on coffee
Aug 12, 2007 News
We all know at least one of those geeks that seem to exist on cold pizza and caffein – but how many of you have seen a machine that truly runs on coffee? No, I’m not kidding. What you see up there is not a toy covering a cup of coffee to keep it warm; in fact the coffee under it (the heat from the coffee to be more precise) has been kept to get the engine up and running.
If you set this fully functional Stirling engine on a cup with cooking hot coffee (date or water do it naturally also), give the flywheel to the left small thrust, the genügsame apparatus begins quietly to stampfen – up to one hour long. Made from sturdy cardboard, it comes with laser-cut aluminum plates, friction-poor plastic axle bearings and wire bending hurry from spring steel.
Sigh, if only everything worked like that. All we would have to do was whip up some great coffee all day, and you can forget all electricity bills.
You sure love the thought of that, don’t you? But while that may be far fetched, you can have one of these for a price of about $44 (not too steep a bargain).
