This is the type of technology that we should be looking into. All the other green initiatives reduce or try to get to carbon neutral. But they do not take CO2 out of the atmosphere. We should keep pushing forward with other green initiatives. But we also need to realize people will support these green deals until their lives are altered. This type of technology acknowledges we wont put the genie back in the bottle. And instead will mitigate the damage by taking CO2 out of the atmosphere and store it.
Ultimately yes. We must find ways of extracting the CO2 we have already put out. Its just that the technology needs to be way more developed and refined.
Any solution that requires massive amounts of energy is not really a solution at all for now. The energy that would power these things would come from CO2 emitting processes. Nuclear would be nice, but, there is too much pushback on it right now sadly.
