The Potter's live off grid near Bancroft Ontario in a Earthship, you can visit them and pay for a tour, nice people I spent a weekend there helping build walls, dig a trench for foundation/wall, and parge/stucco a wall. Plus receiving tons of invaluable info on Earthships. I left them with a parabolic Solar Cooker to help spread the word as they had everything but a Solar Cooker in there Off Grid Life Style because you can't expect to live as you do on the grid off of it.
