Hi Robert, I'm sorry I've only just read the description [1], because I immediately jumped to the conclusion that its significance was as a *champion for the use of algae for serious CDR*, with potential to draw down more CO2 than being emitted while 'only' using one or two percent of the planet's ocean area. The pump itself is almost a distraction!
However Robert appears to want to take the CO2 from concentrated sources, such as coal-fired power stations, and use the algae to turn the CO2 into something else. Thus it is the carbon capture part of CCS and of commercial interest to FF companies. But it does not have a net effect of reducing the CO2 in the atmosphere, as required both for reducing global warming and staying reasonably below the 2 degree C so-called safe limit, touted by IPCC, and for reducing ocean acidification. I found this altercation between Michael Hayes and Robert in the comment section [2] particular illuminating: RT: Yes, I would love to see coal burning become ecologically sustainable through High Efficiency Low Emission technology linked to ocean based algae biofuel production to recycle all its produced carbon. We do have to massively raise the bar, as Michael puts it, to exclude all denialism and develop technology to make energy production ecologically sustainable. MH: “As to the end strategy of bringing the FF industry to the wonderfully idealistic paradigm shift of "turning their commercial interests, resources and skills to advantage for new sustainable technology.": There simply is no plausible indication within this proposal that Mr. Tulip's patented marine bag/tidal pump technologies, nor the stated end strategy can, nor will ever, cause, compel or lead the FF industry into a new 'kinder' profit motive.” I am all for algae to drawdown CO2, but they must take the CO2 out of the atmosphere (or out of solution in water) directly rather than from a concentrated source. And, if they also produce an edible end-product (e.g. fish) or can be converted to a soil improver (e.g. biochar), so much the better for feeding the world!
