Australia to produce seaweed cattle feed that reduces methane emissions by 80%

Seems like if we can manufacture the active chemical (bromoform) without seaweed, it'll be much more scalable.

Then there's also an even crazier idea: create a massive sea in the middle of Australia and use that for seaweed farming.

Bromoform & co. is rather volatile and toxic. The nice feature about seaweed in this case is it has bromoperoxidase pathways, so the halomethanes are produced in low concentrations and bound in (I presume) cell membranes until digested, releasing it right where it's needed, in the fermenting stomach.

You'd have to engineer a digestible slow release halomethane source. Or just...grow it.

How hard can it be to scale seaweed farming?

Really hard, trust me. Coastal areas and sea platform tend to have a high level of occupation.

And at the same time we retire a lot of CO2 from atmosphere.
