Self Suffeicency

I have built an all concrete round house using insulated concrete forms and steel. This highly insulated house seems to be the easiest building to heat and ventilate as well as illuminate. When a building excells in these issues, then supply energy needs is minimized which costs less and becomes more practical. Here's many photos of the hosue and and the 1.5 kw PV system, along with the hot water storage tank, parabolic concentrator and 24volt low energy refrigerator which any one can assemble. Feel free to email me or post a question on the forum. thanks, Ray Cayer
