Wow. Been a long time since I heard that name. But from what I remember, a powerpile is nothing more than several thermocouples wired in series inside a single housing. When heated, this allows it to create more power than just 1 thermocouple. It could then be used to open a gas valve. My first home's furnace was a gravity with a powerpile.
