The year is 2020. I'm having a party to celebrate making it completely off the grid. Two large windmills are towering overhead from behind the house and a waterfall next to the house is powering a hydro electric generator. The waterfall was artificially created by diverting water from the river up on the hill and running it through pipes next to the house. From there, another pipe takes the water back to the river farther down stream. As a sort of a proof of concept, we decide to turn on every electrical appliance to see if the houses electrical infrastructure can handle the power draw...success! We cheer and dance and laugh and sing and so on and so on...it is a good day.
