A couple of days ago I visited a bitcoin friend that has a Willipini house. (Not sure I have the correct spelling)
But damn! It was so cool!
Built with huge cement blocks stacked on top of each other.
Much of the structure built in the earth to capture michigan’s steady 55-56 degree Fahrenheit year round. If I understand correctly, There were some kind of insulating panels (or maybe more cement??) buried, at an angle, to direct earth heat into the building. He had several 6 or 8” tubing running out into the earth 150’ and back, on a steady 2% upward grade to let the warm air rise throughout the system. The South facing wall - all windows. Vents at both ends of the structure high up.
He was creating a small pool to use and at the same time this pool would capture heat from the sun during the day and release heat at night. Water lines, drains, overflow basin; And even more science and systems that I can’t remember. It was Just an incredibly fascinating project and structure. Truly Inspiring.
