Well, if this is real and it isn't just released into the atmosphere, seems to be a good deal. Anyway, and a bit offtopic, is carbon or $gas capture from atmosphere there yet? Why is it not widely used, because of costs, tech, scaling problems? It seems to me that it solves the problem of controlling all the pipeline. If you can just capture gasses out of the atmosphere, suddenly you found a workaround for leaks, other countries not complying, ICEs, etc.
