synthetic gas or any energy dense combustible synthetic fuel would be great. check out the abiotic oil theory. i don't know enough to state it's totally true, but if so oil is a bi-product of the earth itself and is constantly regenerating, so theoretically we could already have a fuel source for the future combined with continuously refining products to be more efficient. mini reactors either in the car itself or medium sized ones placed every 10-20 miles. i think everything has it's place. i think EVs/E-bikes/E-Scooters in a city or in a defined area can make a ton of sense. everyone in large cities doesn't need to own a car (not that you shouldn't be allowed to) and utilizing a fleet of EVs (like i think Tesla is being set up for) does make sense. we have options and we have smart ppl that can create and implement a plan.... but that's not the agenda.
