Earthships and Solar Towers
Friday, April 20th, 2007
Earthships have many interesting environmental ideas incorporated into them: use of recycled tires and cans for construction, passive solar heating, rainwater harvesting and treatment, low draw DC appliances. The basic idea is to construct with massive walls to moderate temperature. You aligning the windows for maximum effect in your location.
I wonder about using tires. Tires are primarily petroleum. I would not want to be in a well sealed container made from tires heated by the sun. But they probably aren’t being heated so drastically embeded in earth, and I hope earthships have decent ventilation. Tires can be recycled in other ways.
Solar towers use the chimney effect to drive turbines. This solar power device I’m sure appeals to the folks who enjoy owning centralized power plants. But it is certainly a more welcome neighbor than a coal or nuclear plant. I wonder what to do with all that plastic after its ten year lifespan.
