Hi All,
Been getting cold, so I've been inside pouring through hundreds of patents on heating. I came across this patent (#4503305 Electromagnetic induction air heater) which Figure five caught my eye. Generate heat through steam and a run a generator to recharge the battery. Could remove the mechanical generator and replace with a block of peltier modules on the steam side.
Any thoughts on this patent?
