Why do you obsess on something that will never affect your life, that
you can personally do nothing about, and that is plainly bad science?

Why don't you do something real, something that matters, something
with tangible results? Something that involves soldering irons?

Now we're talking !

I have devised a product for home energy heating efficiency. I may not believe in the
religion of AGW but efficiency I like, esp when it comes to reduced bills.

Trouble is, I need an electronically controlled proportional valve (probably stepper
motor controlled via uC) that can regulate the water flow rates usually found in
European (and other) central heating systems. Plus it has to be cheap in volume
manufacture. I've considered approaching traditional radiator valve makers but I bet
they'd see what I was up to and do their own thing, although they'd miss half the
goodies I have in mind.

Ideas ?
