Water in an Earthship ◦Water is caught from the roof and channeled via silt catches into cisterns, gravity fed into DC pump and filter panels ◦Pump and filter panel push water into pressure tanks and household water pressure is the result. ◦The Toilet is separated from drainage system of all other household plumbing fixtures. ◦Water is used as bathing or washing dishes. ◦This water is then drained into linear biologically developed interior greywater treatment and containment systems.
Geothermal heat pumps, or ground source heat pumps (GSHP) have been around for more than half a century. The technology exploits the constant temperatures we find right below the Earth’s surface, either for heating or cooling purposes, and has significantly higher efficiency than electrical heating, furnaces or even air source he
