I did my first very pathetic test just now: wedged one of the generators under the hot bit of my laptop and (separately!) between my just-boiled electric kettle and my cooling cup of tea.
I did manage to get my multimeter to twitch with what I take to be a few mW of generated power! I'll try and take some pictures of the stuff today, and I may need some advice from y'all grown-ups out there as to the most sensible way to approach testing and prototyping this idea of mine! I'm fairly sure that I have enough bits to be getting on with (especially after I get back to my local DIY store): now I have to Just Do It!
What (Watt?) fun though: waste heat to actual electricity!
And I used the hot water from my kettle, partially powered by my solar PV, to make another cup of brain-rousing tea. No Joule was wasted during this test.
(I am not disclosing if any subatomic particles were discommoded.)
