Biofuel can just be picked up as you go for a walk. Yes, and there's plenty of it. It's plain old kelp, particularly the Laminaria digitata type which grows along the coast of Wales. The plant's carbohydrate level peaks in July. A high level of carbohydrate is needed to produce more ethanol. There is so much kelp in the world lying around beaches. It would be rational to use this resource because little of it is used for human consumption. The plant is very dense in its growth. Much more biomass per square meter is produced than with sugar cane or other ethanol crops. Using prime agricultural land to grow crops to produced ethanol directly affects the supply and price of food. The oceans have almost limitless resources waiting to be utilized. http://www.adventure--australia.blogspot.com/ http://www.tysaustralia.blogspot.com/ http://www.feeds.feedburner.com/AdventureAustralia http://www.technorati.com/blogs/ http://adventure--australia.blogspot.com . . . . . ...
