Anyway.. on with the show. So in my first two ello posts hints to how I'm planning on harvesting heat and electricity from the sun.
The intent is to integrate this in a fully self sustainable working/living space at minimal cost (30k). 10k is reserved for land, in most countries this will get you a few acres within an hours' commute from a town of significance.
10k goes to materials. Solar panels, wiring, roofing, walls, load bearing construction.
The remaining 10k can either be used as a budget for a work-environment at home or as a commute budget. In Europe this buys you a two seater electric car (eg. Renault Twizy) which can be charged with the solar panels.
Anyway, more will follow. Today the tedious calculus to see if the BoM fits the above budget in any way shape or form that makes it sellable as a possibly realistic concept ;-)
