Britgaskets Nexus6.1 stirling backwoods motor. A sneak peek at the cooling stack cuts underway for the prototype. 200+ hours R&D and nice Youtube member input lucky it's not rocket science but reading the 300+ page NASA data on stirlings took a lot of Kraft dinner and coffee to digest! I just want to get to the destruction phase which is my favorite part of product development, I plan on dropping a packed functioning motor from 20+ feet and also use a fresnel to see if I can melt the hot cap! LOL! the kid in me I guess I don't do delicate. Things that break easy are useless for dependability. If your willing to sacrifice the luxuries considered "normal" you can achieve almost anything. You just need to accept when your wrong and be willing to be non-judgemental of those around you. You don't need a make believe religion to be a good human. It's soon going to be shoulder room on this rock and it's time to make it a better place.
