Technical Design
- Best Resoirce as a Design Guide - tight packing fraction of modules appears to be a key requirement for higher power applications - [11] - as also seen in Firevolt.
- DOE design report - 500w on a 200 degree differential from car exhaust - [12]
Conclusions
- If accessible modules put out 3W (5% of 60W) and cost $2, then we have a 70 cent per watt cost at maximum efficiency. This translates to a practical 100W system at $70 in peltier cells, plus balance of system for heating and cooling. If a stove is used, and the cold water side is based on a simple radiator (which adds minimally to space heating) - the cost is feasible.
