Breakfast with Ben and Chi-chan. We talked a lot about Earthships and the possibilities of building them in Japan.
A brief guide to Earthships:
(1) Earthships use passive-solar heating.
(2) Earthships use thermal mass, in the form of very thick walls which hold heat.
(3) Thermal mass is significantly different from insulation.
(4) Earthships do not require any connection to infrastructure.
(5) Earthships are the future and the past.
