Ooh, renewable fuel from seaweed! I know that marine ecology is a lot trickier than ferming, though – paerly because of the large amount of mismanagement in underwater resources. If it is successful, however, cleaning up the ocean and getting a new source of renewable fuel would make a great combination for mankind given our current energy and transportation needs!

    +Jon Uzel it's true that we still need to solve the problem of needing to burn fuel – I suspect that what is hindering us in this respect is more of politics (and politics on what should be researched!) than science and creativity. At the same time, I have the feeling that the status of our marine ecosystems is considerably worse than on-land ecosystems, and raising seaweed and plankton counts would go a long way to making the oceans healthier than they are today. Mind you, we still have enough other problems out there… like the drifting plastic that +Karsten Wegmeyer mentioned, pollutants that have been dumped into the sea, badly managed commercial trawlers destroying ocean floor ecosystems…

    The question lies then on how it's harvested. If it end up like most things, it'll be through the cheapest means possible, which could at least early on lead to small poorly maintained boats polluting the water (or being lost to it) and then eventually large commercial ships, simply doing it on a larger scale.

    They can come up with alternatives for harvesting, based on how quickly the crop replenishes, but there are flaws still in this. Yes, it's renewable, but it's still burning a fuel and we need to be reducing that need period, no matter what the fuel is. Then there's this from the article..

    "One of the biggest criticisms leveled at biofuels that are derived from crops such as wheat, corn and sugar cane, is that they result in valuable land being taken away from food production."

    Do they not know seaweed is edible too?
