There's nothing quite like some science trickery to spicen up your desk at work, to show just how much cooler you are than your coworkers! 

Mini Sterling Engine - Heat powered engine runs off heat from your coffee cup

This low temperature stirling engine, will run right off the heat from your coffee cup, and will not only make for the coolest desk ornament, but will also most likely wow your boss into giving you a raise!

Mini Sterling Engine - Heat powered engine runs off heat from your coffee cup

To use it, just place the mini engine on top of your coffee cup and give it a little push to get started. Since the heat from your coffee will heat the bottom of the engine, it'll continue to run as long as your coffee is hot! And since the engine is trapping the heat from your coffee within your mug, it'll surely run for quite a while.

Mini Sterling Engine - Heat powered engine runs off heat from your coffee cup

The heat powered sterling engine doesn't actually need coffee, as it'll work with any hot liquid like water, tea, etc (or even a flame). The bigger the temperature difference is between the bottom plate and the top plate of the engine, the faster it'll run. If quite different, you can achieve rotational speeds of up to 200 RPM.

The mini sterling engine is made from steel and glass materials, needs a temperature different between the top and bottom plates of 68 degrees F to start the engine, and measures 8 inches tall x 5.4 inches in diameter.

Scientific Principles:

This is traditionally known as an external combustion engine in contrast to an internal combustion engine where the heat input is by combustion of a fuel within the body of the working fluid. Unlike the steam engine's use of water in both its liquid and gaseous phases as the working fluid,the Stirling engine encloses a fixed quantity of permanently gaseous fluid such as air or helium. As in all heat engines, the general cycle consists of compressing cool gas, heating the gas, expanding the hot gas, and finally cooling the gas before repeating the cycle.

Features:

  • Specification - Speed up to 180-200 RPM Start temperaure difference:20 Celsius Color:Silver Bottom Gold Flywheel Weight:322 Grams
  • Learning tool - This engine put on your table to physical/mechanical learning.
  • Put on the cup - Put the stirling motor toy in top of hot water to make the temperature difference. You also can put it in top of ICE to get the temperature difference.
