Electric Car Battery that charges off-grid
A ground-breaking car battery that requires no mains recharging may revolutionise ecofriendly transport.. The Metalectrique battery powers a car for a claimed 10 times further than existing models, Devon-based engineer Trevor Jackson and colleague George Adams say that bench tests indicate their battery is capable of distances of between 1,400 and 4,000 miles without stopping off to re-power.
When the batteries are spent, they are removed and replaced, with the idea that drivers will eventually be able to swap them at depots or services stations at a cost of around £27, working out at around 13p per mile travelled. Known as long-range metal air batteries, energy is transferred through the corrosion of aluminium by a chemical solution. While the driver simply buys a replacement, the spent cells themselves can be re-filled by suppliers, ready to go again.
