Create an array of Ng\'s carbon dioxide to oxygen converters
Campaign: Can we create a new Amazon?
Plant trees everywhere but while we wait for trees to grow, we could reduce CO2 by producing the device created by Cheuk-Yiu Ng, published in the Oct. 2 issue of the journal Science. Ng and his colleagues built a one-of-a-kind instrument to split up carbon dioxide, using ultraviolet light in a vacuum. The device consists of two lasers — one to split the CO2, and one to detect the fragments produced.
The next step would then be storage, reuse in industry or synthesis into renewable fuel. CO2 capture from air seems to be still quite costly, several $100 per ton, as a Swiss start-up is currently up to the challenge with pilot plants (Climeworks).
