uh, read the article?

Post #405,286 by Andrew Grygus 10/11/15 9:15:31 PM Reply	The article is wonderfully uninformative. It's now possible to take CO2 out of the atmosphere, and use it as a feed stock, with hydrogen, to produce net zero emission fuels. I've seen much more credible explanations for New Age energy frauds from back in the early '70s. Details please.

The carbon dioxide from gas combustion is also captured along with the CO2 extracted from the atmosphere, so that no new CO2 is emitted to the atmosphere by our technology. In the longer term, we expect that carbon-free power will drive air capture. CE is building collaborations to conduct full-scale studies on using solar thermal or nuclear energy as the source of energy for its air capture system. It could still be useful even if it costs money or net power to grab a significant amount of CO2 out of the air. But the question remains whether it will be better than traditional techniques if they also have similar "free" inputs. Cheers, Scott.
Post #405,289 by Andrew Grygus 10/11/15 9:47:24 PM Reply	Yes, with unlimited "almost free" electricity . . . . . they can break the bond to produce carbon and oxygen. They also need to break the hydrogen away from something. Then they can re-combine into some sort of "designer fuel". I'd like to see an energy flow and balance diagram here. There are a lot of other things you can do with unlimited "almost free" electricity - if you can get it. I well remember all the "electricity will be too cheap to meter" claims for nuclear power. I've talked to people who suckered for "Medallion Homes" based on those claims. To me, this article reads like a foundation pitch to start sucking in investors who don't know how to do math.

Post #405,290 by Andrew Grygus 10/11/15 10:09:12 PM Reply	Credible science, but major problems. Calculate the square footage of solar collection needed to equal the output of an oil well. All these folks had better pray that the Fusion Reactor being developed by Lockheed Martin's Skunk Works actually works. "Electricity too cheap to meter" is what all this stuff needs.

We're replacing carbon sequestered in biomass with CO₂ and plants that are small and don't use that much of it. Photosynthesis needs to be used or replicated. Make room for those cords of wood! :) Alex "There is a cult of ignorance in the United States, and there has always been.

Post #405,297 by Andrew Grygus 10/12/15 10:59:12 AM Reply	Photosynthesis can't keep up. We're burning the photosynthesis of millions of years in a few decades. It is believed that the last global warming was ended by a huge bloom of aquatic ferns all over North American waters. Today, these same ferns are considered pests and are constantly cleared from recreational waterways in the U.S. and Canada.
