Yeah this is seems like it's reduced the complexity down to one dimension (removing the CO2) and has blown past any of that, didn't even think about the algae initially, just energy expenditures getting this up and running, but yeah, that's pretty much saying you'll solve climate change by chopping down trees and planting golf course grass

They’re not even removing that much CO2 either

> Captura’s Port of Los Angeles pilot can remove about 100 tonnes of CO2 per year from seawater. The company’s new plant under construction in Hawaii will capture 10 times that amount—a measurement the company can definitively quantify.

So 1,000 tonnes of CO2 / year?

So back of the sticky note math, 1,000 ton/yr, at $7.37/ton carbon credit resell value per Google "AI" header thing, that's $7,370/year profit. Hopefully that covers the boat, employee salaries, and fuel. Good job team.

My god, exactly. But I think you mean $7,370/year revenue.

Meh, words. /s

To help quantify this further, a typical passenger car emits ~5 tonnes of CO2 per year. So we’re talking about offsetting 20-200 cars per year.

Only if you ignore the who knows how many tons of CO2 was put into the atmosphere to create the thing. In reality that thing probably need to run several years to break even.

Oh no, the algae, nobody thought of them!

We like them for breathing purposes. They produce about 70% of the oxygen.

And an important food source for the fish we like to eat.
