## Questions & Answers

**Q: Can I connect these in either series or parallel to get more 'end result' power?**
A: A voltage controller is required for multiple times.
Typically 2 tiles 1 controller voltage varies by temperature differential this requires minimum and maximum safety 
Thermal circuit breakers at effective for over voltage.
Diodes can be used for voltage control  these act as a bypass for your buck converter.

**Q: Can I operate the cold side with 12vdc, apply a heat source, and harvest any power generated? Is it possible?**
A: You can apply a heat source to one end, and a cold source to the other and generate about 1.5v of electricity per generator.

**Q: Will one of these run a larger electric motor?**
A: It's only going to realistically generate just over a volt of electricity with about 150 degree temp difference between the 2 sides

**Q: Are these tec or teg tiles?**
A: #21745 is a teg thermal different
Generator. TEG is thermal electric 
Generator number determines the temperature range this is for low temperatures below 200)° f.
Perfect for air cooling
