MIT engineers make converting CO2 into useful products more practical

It's always going to take more energy to convert CO2 to anything useful than it is to burn energy and release it as pollution. That means to requester all the extra CO2 in the atmosphere will require more energy than it took to put it there in the first place. Good luck humanity.

Humans passively polluted the atmosphere. Perhaps they can passively clean it up as well. Electric cars that spend 10% of their energy on sequestration or something like that. Exchange your CarbonBricks for a discount on useless consumer trinkets.

Ultimately, it doesn't matter whether it's distributed or not, the real meat is that the energy used to sequester carbon needs to not come from carbon fuels. Once that can be scaled up, we can clean up at least some portion of this disaster.
