It doesn't matter which plate is warmer, as long as the other is cooler. Can be run on a variety of heat sources including boiling water, hand heat, digital TV boxes, ADSL modems, desk lamps, hot tea or coffee, warm sunlight. Place the engine on a bowl of ice and warm the top plate, then the engine will run in reverse.

Happy, But one minor hiccup.
Style: PKHZZ92-PBK
The media could not be loaded. I have been wanting to order one of these for a very long time and finally pulled the trigger yesterday. I have it set up and running on my desk using a coffee cup warmer as a heat source. It has been running now for about 4 hours and is as intriguing as I hoped it would be. But not without a small problem in getting started. I am an engineer by trade and am fascinated by just about anything mechanical in nature and design. I unboxed the engine this morning and set it up and got it running but noted that it ran slower than expected and had a noticeable ticking noise and a roughness in the motion of the piston. I disassembled the piston and removed the glass tube/cylinder to find the o-ring that holds it in place had been damaged during the assembly process causing the cylinder to be misaligned. I removed the skived off piece, cleaned the cylinder and reassembled it taking extra care in aligning the cylinder. After replacing the engine on the hot plate and giving it a spin it worked like a champ and has been running continuously ever since. It speeds up and slows down as the hotplate cycles on and off so it is not just a monotonous noise but more like a background fluctuating rhythm. Even with this slight hiccup I am extremely happy with my purchase. UPDATE; This engine has been running on my desk for 8 hour a day since the day I got it without a single hiccup. I have gotten tons of comments and questions on it. I would highly recommend it if you are thinking about buying one. I am very very pleased.

Well built and packaged in a reusable container - which is where I keep it when not demonstrating. The clear piston cases demonstrate the Sterling invention. Fun

Started spinning when my GPU hit 74 degrees celsius
Style: HZZ92-BK
The media could not be loaded. Not it's intended use case I'm sure but it's kind of an interesting visual addition to my PC. After about 30-40 mins of playing a game the graphics card will get warm enough for the engine to start working (around 74-75 degrees celsius). The pistons do make a constant tapping noise when it's moving so I don't know how long I'll actually keep it in there since a quiet PC is preferable but it's cool for now.
