This is not going to be a long post, because everything is explained in the video I link to. But essentially we can transform our existing vehicles and infrastructure with the use of synthetic fuel where the carbon is pulled out of the air and reused as fuel thus making it a net zero fuel. The trick will be extracting carbon out of the air at a higher rate then we reuse and release it so that we can start correcting the damage we have done to the planet. Either way, watch the video for a better understanding why synthetic fuels are the future.
