The best future for high octane fuel for our combustion engines would have to be CNG compressed natural gas. Australia steals it off East Timor and sells it to China and Japan at 1 or 2c per litre. The only problem is storage as it needs more volume and tank size would be too heavy. Unfortunately we are at the beck and call of oil still in the 21st century.
