This is amazing stuff. Researchers in Italy have suceeded in experiments to convert the troublesome greenhouse gas carbon dioxide back into hydrocarbons that could be reused as fuel.
Even better, they do this using the sun - not some huge complicated chemical process. They have only done limited experiments so far, and a commercial solution is probably a decade away, but it does show that there is some hope here.
Amazing what humans can do when we put our minds to something. Who knows - maybe the threat of extinction will turn us all around?
