There are inventions that started decades ago. During the "W" administration he stated in speeches that technology would solve the problem of greenhouse gas emissions. I don't know if Bush thought it was a good thing to say in a speech or not, but, people took him seriously and went to work. WHEN IS THE TECHNOLOGY DEVELOPED GOING TO BE MANDATED BY THE FEDERAL GOVERNMENT.
Right now there are CO2 emissions that could be controlled by devices like that at MIT, but, state and federal government will not implement the technology, instead, these polluters of greenhouse gases are provided a status of "unattainable."
These polluters continue their operations with impunity because it may cost money to change their emission stacks. The government won't insist on implementing technology that works because it may cause the loss of business and jobs. That is not a reason to delay any implementation of climate crisis technology.
The climate crisis is costing the USA billions year after year after year. Where are the funds in the form of grants provided to those that can assemble this technology in businesses? The federal government must fund the implementation of technology and in that regulation. Without regulation, there will be no reason to change very dangerous emission methods currently in use. The USA MUST change it's way of looking at the climate crisis and it's resolve. Moscow Mitch's status quo may ensure his wealth and that of his family, but, it does nothing to generations of Americans with diminished quality of life on a deteriorating planet.

"MIT Developed a Controllable Membrane to Pull Carbon Dioxide Out of Exhaust Streams"
By David L. Chandler
Electrically switchable system (click here) could continuously separate gases without the need for moving parts or wasted space.
A new system developed by chemical engineers at MIT could provide a way of continuously removing carbon dioxide from a stream of waste gases, or even from the air. The key component is an electrochemically assisted membrane whose permeability to gas can be switched on and off at will, using no moving parts and relatively little energy.
The membranes themselves, made of anodized aluminum oxide, have a honeycomb-like structure made up of hexagonal openings that allow gas molecules to flow in and out when in the open state. However, gas passage can be blocked when a thin layer of metal is electrically deposited to cover the pores of the membrane. The work is described in a paper by Professor T. Alan Hatton, postdoc Yayuan Liu, and four others that was published in the journal Science Advances on October 16, 2020.
This new “gas gating” mechanism could be applied to the continuous removal of carbon dioxide from a range of industrial exhaust streams and from ambient air, the team says. They have built a proof-of-concept device to show this process in action.
The device uses a redox-active carbon-absorbing material, sandwiched between two switchable gas gating membranes. The sorbent and the gating membranes are in close contact with each other and are immersed in an organic electrolyte to provide a medium for zinc ions to shuttle back and forth. These two gating membranes can be opened or closed electrically by switching the polarity of a voltage between them, causing ions of zinc to shuttle from one side to the other. The ions simultaneously block one side, by forming a metallic film over it, while opening the other, by dissolving its film away....
