did you contact them ? Is hard to build a good quality Sterling.
prob gonna be a couple thousand. most home built ones are in the 3-7% range.
Brillouin is building a LENR device to make hot water. He has figured out the action that all the scientists were using for hydrogen catalyzation on nickle and platinum, and sped up the process to milleseconds, creating a "free" energy source.
Lower down post , you can find a link to build your own.
second link goes to PESN, where you read how it works.
I tinkered around building a couple Stirling engines. There's no danger of becoming a mainstream prime mover anytime soon. I might use it in an emergency for a simple to build engine while you were building something more permanent---but you could just as soon do that with a Tesla turbine which is the simplest method of converting heat to mechanical energy I am aware of. The problem lies in the piston rings. It's hard to find a material or a system like a diaphragm that will hold compression without causing excessive friction in the cylinder. The one they used in the Mars rover was something like half million bucks just for the engine.
Plus, just like a boiler a Stirling requires a heating up period to reaching operating temperatures, during which time you're wasting fuel without getting any work. Where an ICE delivers power immediately.
What's gotten into you? Could it be this tiny ad?
