One of the biggest misconceptions with thermoelectric systems is that every component near the heat source has to somehow survive the same temperature as the flame. That isn’t how the Ember works. The water moving through the system carries heat away continuously, which keeps the cold side and the tubing at a much lower temperature than the actual heat source.
That’s also why heat source flexibility is such a big part of the design. You’re not locked into one specific fuel or burner. The Ember only cares that you can create and maintain a useful temperature difference across the cells. That can come from Sterno, candles, a small stove, hot metal, solar heated surfaces, or plenty of other sources depending on what you have available.
You still need normal cable management and you obviously don’t want wires sitting directly in a flame. But the system itself is designed around managing that heat while turning part of the temperature difference into usable electrical power.
That simplicity is really the whole point of PiggyPower. Heat is everywhere. The goal is giving you another way to actually use it.
