Researching air-carbon capture for use post-2050 remains a very good means of establishing the intellectual capital and basic technologies for when it makes sense...
Solar geoengineering is a bandaid on the symptoms, not a cure for the causes. It's like putting out the fires caused by an arsonist...
A handful of scientists want to dim the sun to cool the planet. A recent debate shows the idea is perilous, impractical — and immensely appealing.
Carbon Engineering will produce transportation fuels that cost 18-25 times more and have 22-35 the CO2e emissions as just using electricity in an EV
Carbon Engineering is planning to build high-cost and comparatively high-emission transportation fuels by combining their expensive CO2 with hydrogen which they will get via...
Air carbon capture, especially as Carbon Engineering is doing it, is a fig leaf for the fossil fuel industry.
Carbon Engineering's solution is only useful in tapped-out oil wells and as greenwashing for fossil fuel companies.
Carbon Engineering's solution would require 2-kilometer long, 20 meter high walls of noisy fans to capture 4 orders of magnitude less carbon than would...
Carbon Engineering's solution is a natural gas hog that produces a half ton of new CO2 for each ton captured from the air.
To scale to an inadequate million tons of CO2 a year, the company would need 2,000 two-meter fans blowing air into contactors in an...
