Right, and that's fantastic, but that's not sequestering carbon. That's growing food.

  Displacement is useful, albeit mischaracterized.

  yes it is. but the point isn't to sequester carbon for no reason, it's to reduce overall atmospheric CO2. and if you can replace more carbon-intensive food production with seaweed farming, that's a win. also, regardless of how quickly it grows and is harvested any sort of farming does sequester carbon for as long as those crops are still crops, and seaweed can (afaik) grow year-round, permanently replenishing itself. if the total biomass in your seaweed farm stays relatively stable at 10T, that's ~10T of carbon removed from the atmosphere for as long as that farm exists. the fact that some of it is getting harvested is irrelevant as long as more keeps growing.

    At least with Bull kelp, it doesn't go year round.

But we do? It's just really expensive, price per kj wise. Especially roasted seaweed, which is delicious.

  It's great for weight loss - low calorie and filling

    I'll have to disagree on the filling, I think I could eat kilograms of it ;)

      It's expensive because we don't grow enough of it. Otherwise it grows like mad, without heavy machinery, pesticides and fertilizers ... so there is no reason why it should not cost much less than it currently does.
