2. Contents
• About temperature difference power genera;on
• Experiment
• New experiment
• Summary

3. What’s temperature
difference power genera2on
• One of power genera;on methods by clean energy
• Use the seebeck effect

4. What’s the seebeck effect
• Make electricity from the difference in temperature
HOT COLD
+ =

5. Process of the seebeck effect
• Something hot put on a side of the seebeck element, and something
cold put on the other side.
cold
hot
The seebeck element

6. Prepare to experiment
• The seebeck element
• Copper sheet
↑The seebeck element
← A copper sheet

7. How to experiment
• Copper sheet aOach the seebeck element
• The seebeck element connect with a miniature light bulb
The seebeck element
↓ copper sheet

8. How to experiment(2)
• Something hot put on a copper sheet, and something cold put on the
other sheet
HOT
COLD

9. Result
• Don’t turn on
• Just make a liOle electricity
×

10. Considera2on
• Conduc;on of heat is not efficient
• A miniature light bulb need more electricity
HEAT HEAT

11. New experiment
• Use heat pipes instead of copper sheets
• Use a LED instead of a miniature light bulb

12. What’s the heat pipe
• The heat pipe convey heat immediately
HEAT

13. Result
LED turn on!

14. Summary
• It’s important that how heat was conveyed
• This take long ;me
to become a prac;cal applica;on
