I read that a french engineer has made cars that run on compressed air, they can run on just one tank for 2000+km which is unbelievable and also they reach speeds of 110km/h and they will be on sale in europ nxt yr for $15.000euro, he used to work as a designer of F1 engines so im pretty sure he knows what he is doing and by the looks of it he ll make alot of money because of our current situation, global warming, drastic weather chages and bad events this is one of the good steps that can be made to stop it all getting worse but time will be wont it.
