The Kontax Low Temperature Differential Stirling Engine shows with one spin of the flywheel a clean and simple way of converting thermal energy into motion.
This engine will operate from many heat sources, including hot water, computer monitor, TV and the human hand. As long as there is a small difference in temperature between the upper and lower plates this engine will run.
Every engine has been tested to run from the heat of a hand.
This engine has been meticulously engineered. As any Stirling Engine enthusiast knows, friction is a major problem with small low temperature differential engines, therefore all potential sources of friction in this engine have been eliminated. Another common problem with LTD Stirlings is heat transfer directly between the plates. Again, all possible routes for heat to transfer directly between the plates have been eliminated.
Based on the pioneering work done by Dr Senft at the University of Wisconsin, this model has been designed, manufactured and hand built in England.
A large number of schools and universities have bought our engines for educational use, the transparent chamber wall and cylinder make it easy to explain the Stirling cycle to students. Many of our engines have been kept running for years on top of coffee machines, computers, fax machines, etc. in shops, kitchens and offices all over the world. Many customers take great delight in running our engines on a bowl of ice or snow, where the engine happily runs, but backwards.
