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. ... show more

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

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. ... show more
