Hi Mountain Don, thanks for your input into the discussion and I totally agree with you! This is not something I am going to rush out and by in place of solar (already being upgraded to bigger system). Proof is something that will have quite an impact for me as well, or I would volunteer to be a test case if they want to give it to me
As I said, my main line of thought is looking at alternative energy technologies that are not weather dependent in any way.
I am still looking at picohydro at the moment since my property along the river is actually quite flat, so there is limited head available, but it is still an option I would like to investigate further.
Hi Len, I certainly am not limiting to one energy source as I already have solar and am in the process of putting up a wind turbine to complement that as well. The thing I want to avoid is the dependency on the weather conditions and so I have been looking at alternatives.
I would be curious to see what hydro systems you would recommend as 40K seems to require a lot of head from what I have seen?! I might be able to get 1-2m worked out, but I doubt I would get much more, if that.
Also, your last message is the type I was interested in for my idea and how teg would work. I think it will all come down to "show me how it works" before I put any money on the table.

I would worry about solid fuel self-feeding. It's possible to predict the way uniform particles behave, up to a point, but it might be risky to change to another sort of solid fuel.
On another thread, Ernie mentioned that 6" is about as narrow as you can make the ducting on a practical rocket system. I think he said something like this: the boundary layer around the outside ends up dragging too heavily on the updraft, as you go narrower than that, and the whole effect you are going for with "rocket" ceases to work properly.

Oh, I get it now.
I still think you'd want a relatively strong updraft to drive the flames into a heat exchanger, for the hot side of the Seebeck device. That might be accomplished with a tube that's narrow, but tall, and with a heat exchanger that allows flames to continue upward un-impeded.
yeah, that is a decent idea, Muzhik.
The problem is tracking the satellite to follow the sun. And then also cooling the cold side of the TEG. Before you know it, you have a fairly complex (and expensive) system.
well tracking with a old 7-12 foot c band dish that people re purpose to solar trackers anyway can be done 'easy' and cheap. there are cheap sensors that come on if they are shaded. so you put a small divider inline with the axis with one ssensor oon either side connected once the shade hits the sensor the jack will move the dish. i would power this with a small solar panel so no light no move as for resetting the dish pointing east at the end of every day havent thought of that Smiley you can adjust the height of the arc with the bolt on the old mount
