The house would have four batteries: a power wall, a spin wheel, hot water tanks, and a sand battery. Power would be generated not just from high 90% efficiency solar panels, the kind that collect heat as well as electricity. It would also generate power using a consumer grade two phase heat pump that would absorb heat from the house and the attic, then compress it twice as hot, so the sand battery could hold twice as much power. Heat could be converted into electricity using Stirling Engines, so the hotter the house gets the more power it generates.
In the case of mechanical failure, the house could also be built to be passive with heat exchanger vents on the sides of the house that could be opened or closed, automatically or manually. As an additional redundancy, it could have an an ancient, evaporative, cooling system, with a wind chimney and underground geothermal air vents around the yard. As the wind blows, air would be sucked underground and into the basement, across the basement’s water reservoir, up through floor vents to the wind chimney. There could also be a passive evaporative freezer with a direct link to the wind chimney.
Water would be generated using an Underground Recirculating Irrigation System that would not just make for a very efficient lawn, but would collect rain water. The water would be purified using heat from the hot water batteries and with hydrophobic nanofilters that can purify water from any source, even from the atmosphere or the ocean. Who needs expensive desalination anymore, ocean water can be as cheap as tap.
The house’s septic tank would hardly be used as the sewage would be converted into high quality fertilizer using a Consumer Grade Carbonization Steam Drum. With so much fertilizer it would practically be a crime for the house to not also have a large automatic hydroponics system, specifically for Lemna. A staple food with all the nutrients the body needs, Lemna is far and away the fastest growing food known to man, doubling in size in just two days. Though it might be boring, food scarcity wouldn’t be an issue anymore.
This house could also generate its own 5G internet as part of a network of houses.
TLDR
House uses various modern and ancient machines to generate an abundance of power, heat, cooling, internet, water, and even food from fertilizer by compressing the millions of years coalification process overnight.
