Consumerism

“From 1900 until 1989, U.S. population tripled while the use of raw materials multiplied 17 times. With less than 5 percent of world population, the U.S. uses one-third of the world’s oil, 23 percent of the coal, 27 percent of the aluminum, and 19 percent of the copper. Our per capita use of energy, metals, minerals, forest products, fish, grains, meat and even fresh water dwarfs that of people living in the developing world. “

Solar Balloon Technology

I love to see innovation. Check out this new solar balloon, which has the potential to create 400 times the energy of a normal solar cell.
