A couple of months back, a government document accidentally revealed that Dyson has started work on its own electric vehicle. The company’s great with vacuum cleaners, hairdryers and all manner of home electronics, but an actual vehicle? Dyson may actually have what it takes, according to the experts, thanks largely to Sakti3, a battery company Dyson gobbled up last year.
Sakti3 has a patent for a rechargeable, all solid-state battery that could prove safer and longer-lasting than those currently used by electric car companies. Though we don’t yet know exactly what sort sort of energy density the company has achieved, Sakti3 (surprise, surprise) claims that no other solid state batteries with ceramic electrolytes come close, and experts reckon it’s already hit the 300Wh/kg mark.
To put that into context, MIT’s Donald Sadoway recently said that energy densities of 350Wh/kg would give electric vehicles 350 miles of range, and spell the end for petrol.
“Dyson have some excellent product engineering and some excellent marketing skills, so could they follow the same path as Tesla? Well, yes, probably they could,” said Professor David Greenwood, who leads the energy storage work at the University of Warwick’s manufacturing group, in an interview with the Guardian.
However, he added that it would take several years to scale up to cost-effective, high-volume production, and building a quality vehicle is an entirely different project. Still, it's a very promising outlook for the suction specialists. [Guardian]
