RE: [RC] Diesel at $3 a gallon - LaFollett, MeganThat's why I mentioned algae as a source of biofuel earlier. While using corn/soybeans/etc to produce biofuel is a nice way to subsidize farmers already growing those crops, there is no way to meet the nation's fuel needs through traditional crops. Even with soy, there is only (on the generous side) about a 3.5:1 return on energy investment. Certain algae crops give a 5-10:1 return even without genetic engineering. AND, perhaps of greatest importance, algae can be grown quickly and on land that is USELESS for farming. ~Megan -----Original Message----- From: Barbara McCrary [mailto:bigcreekranch@xxxxxxxxxx] Sent: Thursday, April 06, 2006 3:36 PM To: LaFollett, Megan; ridecamp Subject: Re: [RC] Diesel at $3 a gallon There is one issue about biodiesel that bothers me. I'm not convinced there is enough land to grow enough corn to make enough biodiesel to satisfy the needs of everyone here in the USA. Furthermore, in order to grow that corn, farmers must use tractors, which run on fuel. And the fields must be fertilized, using chemical fertilizers that are made from...oil. Now we could use the slurry from dairy barns, or the manure from hog-feeding operations, but then again, large trucks will be needed to haul that manure to the growing corn fields. That takes time and man-power in excess of what it takes now to haul sacks of chemical fertilizer and distribute them onto the fields. It would also take fuel to transport the larger number of trucks that it would take to haul the manure, as opposed to the number it would take to haul chemical fertilizers in sacks. Does anyone think biodiesel will really solve our energy problems? Think about it. With the nation's current population, we couldn't even go back to driving horses for transportation, should anyone be willing to do this. Where, and how, would the nation grow enough hay to feed all those horses? And can you see anyone but us endurance riders nowadays putting up with the smell, flies and horse poop on the streets? No way. This issue makes a really interesting game of trying to think how to make alternative energy sources work.
