> All in all, super-powered seaweeds could sequester around 173 million metric tons (190 million tons) of carbon each year, about as much as the annual emissions of the state of New York.
It's not that much in comparison to the emissions of the entire industrialized world.
Every bit helps of course, but it's not a magical solution to our problems.
Extensive farming would likely have the natural rate of sequestration.

There's some really cool stuff happening in this field. IIRC some farming designs have been open sourced, too.
All you really need is a few hundred metres of rope and some seed spools.
