If Trevor Jackson, who owns Austin Electric and the rights to use the Austin Motor Company logo, is successful in his fuel cell venture, then that could certainly steal a march over the limitations of lithium ion batteries.
He, apparently has invented a non toxic electrolyte that is triggered by scrap aluminium. He claims a car could be converted for around £3,500 with a running cost around 7p/mile, turning any car into a hybrid. A Tesla S is claimed to have a battery range of 370 miles, whereas a fuel cell of equal weight would give a range of 2,700 miles, no need for charging points, fuel stations could become fuel cell retailers as he claims a very quick cell change time. Currently he's supposed to be making fuel cells for tuk tuks in the Far East and also for bicycles. If this comes off, the range of vehicles would be far more acceptable to what's on offer at the moment.
