Rarinn's Ideas

I noticed that photovoltaics are really cheap now. 19.8 kW of peak power would cost around 20 000 PLN (1 USD is equal to 3.65 PLN when I am writing this). Array of 44 of those, with peak power of 475 W each, which actually will be closer to 450 W, because of marketing and degradation progressing with time, will produce aforementioned amount of total peak electrical power. I accounted only for the initial fast degradation, it will slowly get even worse. Appropriate hybrid inverter costs 11 000 PLN.

Folder “new_house” contains drawings of the thin-walled reinforced concrete structure designed to to house a family of humans. Interior structure is surrounded by a thin shell. In between those a thick layer of thermal insulation (mineral or glass wool most likely) would be present. Some insulation is placed in-between interior concrete structure and the ground. Most of the surfaces of this structures are hyperboloids of one sheet . To maximize usage of interior space, shelves and desks specially designed to be placed next to the curved walls should be installed. Proposed windows are rather small, extremely thick and hard to open (actually to be removed), so light tubes could be used to make rooms brighter. Because windows are always closed, decent HVAC system is required.
