I think it's amusing they still talk about capturing waste CO2! Literally every venture involving plants can make the same claim, from vegetables to ornamental flowers. They're not even pretending to have energy technology any more (probably a smart move as the lies were so ridiculous) and that was the only way they had a sort of plausible to stupid people way of saying they could meaningfully capture waste CO2. No one wants to make food or medicine from toxic industrial waste, so they're just talking about the algae being a plant that uses the air, like any other plant.
