I don’t see how this is “carbon negative”. True, it is removing carbon from the oceans, but the carbon will ultimately be released to the atmosphere in the same way as any land based agricultural crop.
have the same question, which I don’t think the video answers, but I can imagine, for instance, if seaweed were used as an addition to agricultural fields, as many cultures have done, it could sequester carbon in soils. There may be other routes.
One of the ideas for seaweed is to use it in animal feed. Studies have shown that it reduces cow burps of methane quite a bit and helps with lowering methane in cow farts also. It can also be used as a soil amendment as Peter suggests. Any of that is at least more a part of the “natural” carbon cycle.
I suspect the “carbon negative” BS is just a marketing ploy to get you to sell your Solar Roadway stock and invest in seaweed farming, but, if you did, you would be far more likely to make some $$$ and do the environment some good.
There is some value to even temporary storage* of carbon, acting as a delay buffer in the system. Even if it’s carbon neutral, there may be local environmental benefit from reducing carbonic acid (ocean acidification).

Actually seaweed salad is very nutritious and tasty. Have you ever had it?

love seaweed salad. my body craves it.
