Hopefully governments don't do any more harm than they already have, but it's a certainty that they will. Gasoline and gas components could be polymerized into diesel components and the spare hydrogen used to upgrade some goop to diesel. It's all just a matter of where the most bang for buck can be had. The carbon chains can be yanked around in any direction if the money is waiting at the end of the line. In NZ, methane was turned into methanol, then into gasoline. Then the gasoline part was turned off when methanol was too valuable. Methanol might have been turned off too [at least one plant]. The problem with internal combustion engines on vehicles is that they are small and therefore inefficient compared with power stations which have about 30% or 50% better efficiency [and more if the waste heat can be used to warm swimming pools or something]. The reason to have engines on vehicles is because not enough electricity can be supplied - the cost of refueling stops is high so people prefer to spend more money on having an engine as well as electric motors and batteries than stop frequently to fill 'er up again. Hybrid vehicles are wasteful. Eventually it'll be all-electric with some battery and some on the hoof electricity supply [like trams hooking up to cables or electric rails or something]. I have an electric car design in prototype stage now in my shed. There are only 5 moving parts = 4 wheels/motors and the vehicle itself [there is also a windscreen wiper, two doors, sliding seats, hatch-back, glove box, but those aren't really "moving parts". It can go in any direction by simply moving a joy stick, or by remote control using a "remote", or by simply putting in the destination GPS, and orientation [over the internet or by other means] It will be for city use only, at 60 kph speeds, but maybe a bit of city motorway use at 80 kph would be okay too. Right now, it's 60 kph only. I haven't installed the motors or electronics, wheels, seats, body etc, but it's got racing stripes on [well, the paint is in the can ready to apply]. Mqurice
