Sustainability is here to stay or we may not be.

I am in charge of all things environmental at Maine University. I am responsible for the environmental budget, allocating funds for sustainability projects, reducing the University's environmental impact, for external reporting and for heading up the Sustainable Development Team. I work closely with members of the University Executive Team and colleagues from the Colleges and Professional Services to ensure that sustainability is central to the University's core strategy. I joined Maine University following a varied career as an environmental manager in manufacturing, consultancy and on major infrastructure projects as well as a corporate role for a principal contractor.

Machine Captures CO2 From Air And Turns It To Fuel

From their website: At Carbon Engineering, we’re commercializing two clean energy technologies that can rapidly accelerate our shift to a net-zero world: our Direct Air Capture technology can deliver large-scale negative emissions by removing carbon dioxide directly from the atmosphere; and our AIR TO FUELS™ technology can significantly reduce the carbon footprint of transportation by creating clean synthetic fuels – made from air, water and renewable power.

Have you heard of this technology?

Then why not install these right at the production of CO2, i.e. In power plant chimneys???

A complete and massive waste of subsidy. Thermodynamics cannot be cheated. You have to invest way more energy to turn CO2 back into a fuel than that fuel would generate again later on. If you use carbon sourced electricity for this, it truly is an excellent way just to use up valuable energy.

You seem be really uneducated because if you put in energy into a molecular bond and you will then use it for energy in this case burning hydrocarbon chains it will release the same amount of energy as you putted into it. Energy does not just disappear like that.

I know a much more advanced system. It's called TREE

Plant trees and flowers, they do it for free :D and even look better....

this would be brilliant if we had a carbon tax and companies had to off-set their carbon somewhere else

The"smoke stacks" shown at 1:50 are steam vents. The first ones show clearly steam being vented to atmosphere. Watch how quickly it dissipates into the sky. The second footage is at sunset with a yellow cast refracted twilight on it and the camera is using a color filter to enhance the evil look. You may do this with any steam kettle.
There are polluting compounds in the steam but already very low amounts relative to the amount of just H2O. Industry in North America has had carbon scrubbers on the stacks for decades. That is why the visible smog of the 60s and 70s has disappeared over major cities. China has the visible smog today because they weren't using the stack scrubbers until recently.

So that is why Calgary isn't proposing putting them at point sources. Something, long proven, is already there. However putting them in extremely remote deserts where water is at a premium and CO2 levels are already lower than cities and humidity bubble valleys like say Chattanooga TN seems a silly proposal. If efficient, they should be placed where CO2 levels are initially higher, BEFORE CO2 is dispersed to low CO2 areas.

This is probably not the pitch of the actual research engineers, but the marketing people that produced the video. What know they of science and engineering?

I am about to publish a paper that will solve the CO2 crisis forever. It is highly technical and needs people that are experienced for years. It starts with planting trees but then comes the really difficult part. And that is don't cut them down without planting new ones.

No we are not experiencing unprecedented climate change because climate has always been changing.

Then you're going to turn the rest of the land into that Barren Wasteland you showed , but hey at least you'll have spent billions of dollars doing it nice job.

Carbon capture has existed for ages. Its called"Vegetation"
