Yes, while the world may move on oil, it doesn't have to be limited to fossil fuels. Check Wikipedia, or do your own research on Algae Oil or Algae (Bio)Fuel and you'll see what we should be putting our efforts into developing. Here's a bit from Wikipedia: "The United States Department of Energy <http://en.wikipedia.org/wiki/United_States_Department_of_Energy>estimates that if algae fuel replaced all the petroleum fuel in the United States, it would require 15,000 square miles (39,000 km2) which is only 0.42% of the U.S. map.<http://en.wikipedia.org/wiki/Algae_fuel#cite_note-Hartman-10>This is less than 1⁄7 the area of corn <http://en.wikipedia.org/wiki/Maize> harvested in the United States in 2000.<http://en.wikipedia.org/wiki/Algae_fuel#cite_note-11>However, these claims remain unrealized, commercially. According to the head of the Algal Biomass Organization algae fuel can reach price parity with oil in 2018 if granted production tax credits.[1<http://en.wikipedia.org/wiki/Algae_fuel#cite_note-parity-12>" - Rick Gravrok, Monterey Cohousing Community, Minnesota On Sat, Jul 16, 2011 at 5:49 PM, Norman Gauss <normangauss [at] charter.net>wrote: > > There is a tendency to forget that the world moves on oil.
