You're right....in more ways than one. For one thing, the cylinder would have to have the fins removed, silicone grease applied to the heat sink, then the modules, and then fins added to the outside to get much of anything. Also, with the modules I have been playing with, the temp differential should be in the 250-300 degree F range to get close to optimum output. Using exhaust, the modules could be made as kind of a premuffler which would cool the gases, aiding in the muffler effect.
My findings so far say that it would work, but it would be a very expensive way to generate power. My module was about $70.00. I would need 4 of them in a series parallel arrangement to deliver 6 amps at 15.2 volts. And that is the optimul result.....toss in a little reality and it would be marginal as the old Lucas system on my old Beezer. I don't miss those banzai runs through the gears and at about 70+....+........+ the zener goes out along with the lights.
