By the way, did anyone see this study done by several institutions, funded partly by NASA, including Woods Hole, Princeton and others, published in SCIENCE Mag saying corn-based biofuel may nearly double greenhouse gases as compared with gasoline when farming practices and land use are taken into account? http://news.yahoo.com/s/ap/20080207/ap_on_re_us/ethanol_global_warming "The widespread use of ethanol from corn could result in nearly twice the greenhouse gas emissions as the gasoline it would replace because of expected land-use changes, researchers concluded Thursday. The study challenges the rush to biofuels as a response to global warming. The researchers said that past studies showing the benefits of ethanol in combating climate change have not taken into account almost certain changes in land use worldwide if ethanol from corn — and in the future from other feedstocks such as switchgrass — become a prized commodity. "Using good cropland to expand biofuels will probably exacerbate global warming," concludes the study published in Science magazine." That's pretty scary since that program is expanding so rapidly in this country. Neat calculator.
