Here is an interesting link to an interesting concept called Solartopia. According to them, Solartopia is a a democratic, green-powered 21st Century civilization that is based on total renunciation of all fossil and nuclear fuels, all-out conversion to renewable energy, (primarily wind, solar and bio-fuels), complete commitment to maximum efficiency, and zero tolerance for production of anything that cannot be re-used or recycled. Big words with even bigger meanings, an almost impossible goal. Do you think it will ever happen?
