Bring the 2nd law of thermodynamics to life using this device that can act as a refrigerator or a heat engine. Immerse the two aluminum legs in baths of different temperatures, and produce electrical energy that turns the turbine! Unplug the banana jacks and measure the voltage output with a multimeter. A teacher guide is included, making it a perfect option for classroom lessons.

Features:

• Thermoelectric generator demonstrates the 2nd law of thermodynamics
• Comes with a helpful teacher guide for use
• Excellent option for classroom lessons or as part of a science project

Note: Photo shows 2 water baths for demonstration purposes only. Water baths not included.

   Maureen Sullivan from Dallas, Tx.
This item worked very well in my Physics II class. The fan turned within a few minutes of submerging the metal in boiling water and water with ice.


  Very good generator.
da Silva from Rio de Janeiro
It's a great prototype generator and fully works. My students loved.


  good demo of power for space travel
Mike from Sandia Park, NM
Used in 5th grade classroom for transformation of energy demo. Students were very interested. It is also a good demo of how outer planet probes can produce power from radioisotope heat sources. This unit needs a fairly large temperature difference to start the small motor but it runs at lower temperature differences
