The environmental and social costs of producing biofuels on land can be avoided by farming seaweed, says Ricardo Radulovich.
Hopefully this will replace all land grown fuels. I wonder how we put this and other plans into action. We must do something real soon. Well I said the same thing in 1975, or a least I knew then that our oil time was soon to be over,at least the easy part.

Good point, but I still don't think biofuel is the ultimate answer. Even more problematic, farming seaweed requires an incredible amount of energy (powering boats, dropping nets, drying, transport, etc). It requires .8 gallons of petroleum to create 1 gallon of ethanol (which takes a car about as far as .8 gallons of petroleum), so I'm gonna guess that it takes even more petroleum to make a gallon of seaweed biofuel. In the end, it's likely to be false economy.
I agree with David. We need to thoroughly examine this alternative and shouldn't be hasty as we were earlier. I think the key is the use of wastewater from industries and domestic outlets. Proper management of wastewater can turn it into a very useful resource.
Present high price of cooking oil in Asia (Thailand, Pakistan and other) is caused by the growing use of biofuels. Therefore, the need of alternate source of energy and alternate biofuels is there. I think it is good idea to use vast oceans and industrial wastes for beneficial use. But all kinds of EIA's should be carried out before large scale implementations.
Why go to sea when we could have a suburban/rural energy rich Lawn Grass as a solution.
Modify the common yard grass...
The weekly lawn trimmings would go to a local processing facility (think sewage processing), and the processed fuel stays within city limits thus no long distance transportation.
Heck might even make being the neighborhood kid with the lawn mower popular again.
How about growing food instead of grass, cutting need for 'food miles'!? Seems a lot less risky and difficult than 'modifying' the grass strains.
