Thankyou Cate, from someone who had "Meanwhile, Back in the Real World..." T shirts printed, to give away. Lucky me, I met enough worthies to run out of shirts. Years ago I helped build and test a homopolar electrical generator (n-machine) and am familiar with the noxious vapour of hype, b.s. and egotism which such enterprises generate. I am also familiar with the rising tide of public interest in alternative energy sources, and I lke to tinker. I have built a couple of working models, so I have a mental handle on the principle. My challenge is to make electric light from the chimney of my stove. I can already do that with an LED on a motor/generator spinning off one of my models on the stove top, albeit with an ice cube 'cheat'. I don't see much on these forums to excite me, but I enjoyed your post. Thankyou.
