Dyson has scrapped its electric car project

Dyson had planned to invest more than £2bn in developing a "radical and different" electric vehicle, a project it launched in 2016. It said the car would not be aimed at the mass market. Half of the funds would go towards building the car, half towards developing electric batteries.

In October 2018 Dyson revealed plans to build the car at a new plant in Singapore. It was expected to be completed next year, with the first vehicles due to roll off the production line in 2021.

[...] Dyson has concluded it simply can't afford to play with the big boys - although its efforts to make a quantum leap in battery technology will continue. [...] Sir James said Dyson would continue to work on the battery technology, which was used in the car. "Our battery will benefit Dyson in a profound way and take us in exciting new directions."

    That in turn is turbo charging the ancillary technologies of battery design and recharging infrastructure & standards.

    Both which remain way behind what is needed. Sorry, I don't buy that a chemical battery (or indeed any battery equivalent, like a flywheel where chemical bonds are a limit of the energy the battery can contain) can ever be competitive with the energy content of a tank of hydrocarbons, even with exotic, high energy reactions (involving stuff like fluorine and the more exciting metals). Nuclear and such is a different story. But chemical batteries have to compete with a chemical storage system that a) doesn't need to store the oxidizer part (only a few batteries use air as the oxidizer), and b) doesn't need to store the waste reaction products either (no battery can do that).

    The only thing that keeps electric viable is the considerable inefficiency of the internal combustion engine which is limited in efficiency due to the maximum heat load that various critical parts of the engine can withstand. Maybe some sort of staged combustion (allows for much hotter combustion, increasing efficiency) gas turbine/electric combo (since electric really is a nice way to transfer power to the wheels and already exists) could do it, but that's not going to show up on a commercial vehicle in the next ten years.

    Latest gasoline ICEs are over 40% thermal efficiency and pushing on 50%. Takes a combination of turbocharging and clever controls but this is coming to production in the near future.
