... my first thought was that it would have been as good as it was going to get as soon as you came to after surgery. Here's hoping that I'm wrong...
BTW, I'm still trying to come up with the best way to get electricity from the stream running through my lot in the mountains but fast moving water after big rains tend to make a mess of things. I remember some sort of gig that would trial behind the boat but that was nothing more than a trickle charge as far as I can recall.
A bad ass tree house with solar panels and some wind generators perhaps but with the cost of buying and maintaining the stuff, I mine as well hook up to the grid. Maybe thermal? Idunno...
My best to you an Pam...
