<<Suppose, just suppose that you had a generator that self powered and
lit a couple of 200 W light bulbs at the same time.
What would you do tomorrow?>>
I'm not sure what I would do if I had one but as it's you, I would kidnap
you ASAP and ask for nothing to let you go but a piece of paper saying "IOU
1/10th of a percent of any assets I may have in 2020" : )
Seriously, I've read the other suggestions. They mostly seem to go with full
disclosure. This would get the device out into the big wide world but the
inventor wouldn't get much reward from his work UNLESS the theory and art
behind it is unobvious so that, although people could easily replicate the
existing device and generate 500 watts, they would be unable to immediately
scale up and build their own 10kw generators without needing access to the
intellectual property of the inventor...
