Call me a cynic, but I don't believe it. The problem with any fuel cell (primary cell) solution is instantaneous energy delivery. Chemical reactions of that nature are inherently slow. We experimented with a hydrogen-air cell 4y ago to power a chair - it could produce a few 100 watts but at relatively low current - fine for constant speed on the flat but useless for turning, etc. Plus the hydrogen cylinder was massive.

I smell BS too... :fart Like the rest of alternative battery tech, it'll come to nowt!

Lets examine just a couple of his 'claims'...

Also found in devices such as computers and mobile phones, lithium-ion batteries are rechargeable. Almost every electric vehicle on the road uses them. But they have big drawbacks. As well as lithium, they contain rare, poisonous substances such as cobalt. They can explode or catch fire, as seen with the spate of incidents that forced Samsung to recall tens of thousands of Galaxy Note 7 phones in 2016.

LiFePO4 -- Theres zero cobalt, and no way it can catch fire.

With repeated charging, car-sized models eventually become spent. Recycling them to recover the cobalt and lithium is extremely expensive – about five times as much as the cost of disposing them and starting from scratch.

Rubbish. The lifespan of the battery in a tesla has already been shown to exceed 300,000 miles... And still going. Thats more than most cars ever do. Most in europe, are under 1/3rd of that whenb scrapped. And the valuable batteries then get sold on for solar or other uses.

Aluminium, on the other hand, is the planet's most abundant metal. Many of the factories that refine it from ore or recycled junk are powered by green, renewable energy, such as hydro-electric dams.

True but so far the specs of this battery are all in his head and it needs re$earch... $$$$$ just like all the others that vanish without trace.

And once an aluminium-air fuel cell is spent, it can be recycled very cheaply. According to Jackson, the cost of recycling means the running costs of an aluminium-air powered car would work out at 7p per mile. The cost of a small hatchback's petrol comes to around 12p per mile. More important, lithium-ion batteries are heavy.

Tthats half the price of petrol cars, as this is NOT rechargable. WAY more expensive than recharging a lithium car!!!

Accredited tests have shown that, weight for weight, Jackson's fuel cell produces nine times as much energy as lithium-ion: nine times as many kilowatt hours of electricity per kilogram. The luxury electric car maker Tesla says its model S has a range of 370 miles from one charge. Jackson says that if you drove the same car with an aluminium-air cell that weighed the same as the lithium-ion battery, the range would be 2,700 miles. Aluminium-air cells also take up less space.

And then you throw it away? 9x the cost of fully recharging a tesla is much less than 80 uk pounds.

Jackson claims that if the Tesla were fitted with an aluminium-air fuel cell that was the same size as its current battery, it could run non-stop for 1,500 miles – almost enough to get from Land's End to John O'Groats and back again. An average British family – whose car will travel 7,900 miles annually – would need to change their fuel cell only a handful of times each year.

So the 9x is now 4.3 times further? So the claim has now halved. IF the claim is correct, (very unlikely) then after you rechqarge a tesla 5x you throw away the entire lithium battery. Which is the size of the complete floorpan of the tesla car. And replace with a new one. You would need a ramp, a crane, a fork lift truck, and a mortgage.

Aluminium-air fuel cell (Aluminium-air battery) has been around for 10+ years and they just pull it out every year or 2 to hype it up because the grant $ start to drop

Quite.

Investors = gullible idiots in so many cases.
