I see algal production working well on...Good point. I see algal production working well on a local level grown in a "village pond" you might say. So indeed, as a crop that can be grown without using high quality crop-land, with saline water and its other advantages, it may serve to contribute as a food source.<br /><br />I gave a lecture at Kingston University in London a couple of weeks ago entitled " providing Fuel, Food and Pharmaceuticals - Once There is no More Oil" where I dos tress that algae in particular can serve as non-oil-based carbon feedstock for food and chemicals, rather than just an oil-fuel substitute.<br /><br />I might summarise that in a posting here to show my views on the subject.<br /><br />Regards,<br /><br />Chris.Professor Chris Rhodeshttps://www.blogger.com/profile/12060542089215379056noreply@blogger.comtag:blogger.com,1999:blog-19508699.post-38643139519241496232009-11-21T20:43:09.660+00:002009-11-21T20:43:09.660+00:00This doesn't make any sense to me.
If you ca...This doesn't make any sense to me. <br /><br />If you can produce large quantities of protein and fat, omega-3 fats in particular, you shouldn't be trying to convert the fat into biodiesel and the left over biomass into ethanol/DME/diesels.<br /><br />What you should be doing is producing a fish-feed that can replace fish-meal and soy for fish-farming. It requires much less processing than making biodiesel and it puts an armada of fishing vessels out of work(including the fuel they consume). Fully half the worlds fish is farmed rather than caught, with cheap protein and high quality fat from algae this industry could grow even more rapidly.<br /><br />Next you should be thinking about how algae can be used directly, safely and deliciously for human consumption. Wheat was once disgusting; then we figured out that you can make bread, pasta, pizza, buns, cookies, textured gluten meat-substitutes and all sorts of other goodies that make wheat delicious.<br /><br />I think it's very likely that oil is already well into decline at the point where you're ready to move on to biofuels from algae. Oil will have already been partially substituted for by electrified rail, electric or CNG vehicles and nuclear powered ships. You're probably going to want to make use of algae oil as a feedstock for pesticides, plastics, medicine, explosives, elastomers, glue etc. rather than a fuel.Soylenthttps://www.blogger.com/profile/08125903130939473555noreply@blogger.com
