Since a few days several websites report about an alleged revolutionary electric vehicle fuel cell that enables 1500 miles range:

Last Friday, the battery's inventor, British engineer and former Royal Navy officer Trevor Jackson, signed a multi-million-pound deal to start manufacturing the device on a large scale in the UK.
Austin Electric, an engineering firm based in Essex, which now owns the rights to use the old Austin Motor Company logo, will begin putting thousands of them into electric vehicles next year. According to Austin's chief executive, Danny Corcoran, the new technology is a 'game-changer'.
In 2001 he began to investigate the potential of a technology first developed in the 1960s. [...] At that time the method was useless for commercial batteries because the electrolyte was extremely poisonous, and caustic.
After years of experimentation at his workshop in the Cornish village of Callington, Jackson's eureka moment came when he developed a new formula for the electrolyte that was neither poisonous nor caustic.
[...] Another problem with the 1960s version was that it worked only with totally pure aluminium, which is very expensive.
But Jackson's electrolyte works with much lower-purity metal – including recycled drinks cans. The formula, which is top secret, is the key to his device.
The Mail article mentions electrolyte toxicity and causticity and aluminium purity as the main obstacles for the technology to come to markets, that Jackson claims to have solved.
Given CO2-neutral energy exists in sufficient quantities: Is an infrastructure that recycles used Al-air batteries by Al smelting and powers electric cars with them realistic? Are the obstacles that Jackson claims to have solved the main ones or are there other, as yet unsolved problems?
Note that this claim is about fuel cells that can be recycled industrially and carbon-neutrally. The article does not claim that Al-air batteries can be recharged by individuals!
