Ok, I'm not a scientist. AT ALL.
So what happens if you take too much CO2 out of the air? Like, all of it? Isn't there supposed to be a little bit?
Then all plants would die. But there is little chance of this process, even scaled up, would do more than lessen the man-made CO2 that goes into the atmosphere. We just passed the 400 ppm threshold. To get it BACK to 400 ppm would be a major undertaking. I see little hope of that happening. FWIW CO2 was 2000ppm during the Jurassic and Triassic periods, the age of the dinosaurs. So it's not as if the world will end of it keeps going up. And mankind won't suddenly disappear. It's just that life won't be the same as it was and the seacoast cities might develop a wee flooding problem as seas rise. It's all happened before--without our intervention.
Would planting mass crops of trees help absorb enough to get back to the 400 ppm? It would take 15-20 years for them to grow but I am talking about planting trees on a massive global scale?

The process is cheap, efficient, and scalable, meaning it could soon be used to remove large amounts of CO2 from the atmosphere.
Scientists at the Oak Ridge National Laboratory in Tennessee have discovered a chemical reaction to turn CO2 into ethanol, potentially creating a new technology to help avert climate change. Their findings were published in the journal ChemistrySelect.
The researchers were attempting to find a series of chemical reactions that could turn CO2 into a useful fuel, when they realized the first step in their process managed to do it all by itself. The reaction turns CO2 into ethanol, which could in turn be used to power generators and vehicles.
What say you ATS? This looks like good news on 2 fronts, one being reducing c02 for you global warming silly's. And on the other hand a fuel/energy source. Of course with any technology, there is potential for bad, or in some cases, it is ignored and swept under the rug. I do believe that we already posses the tech somewhere to fix the planet's, and societies ills.
Anything to replace or at least supplement oil is also another good thing.

So we will be polluting just to unpollute.
The disruptive energy storage technology developed by Dr. Mets in his lab has been validated by Electrochaea and is now being shown to scale in a commercially meaningful way,” said Cristianne Frazier, senior project manager of technology commercialization and licensing at the Polsky Center.
The process starts with surplus electricity that is coming from a wind farm or solar array, but isn’t needed immediately. That [excess] power is used to convert water into hydrogen and oxygen. The hydrogen is combined with waste carbon dioxide from any of a variety of sources, such as a biogas or an industrial process, in a proprietary bioreactor in which the microorganisms efficiently catalyze conversion of the mixture into methane and water.
I would bet a dollar, that the best place to get CO2 would be an electrical plant, especially if it is burning natural gas, and using their waste product.
