“Dyson has had hundreds of engineers working round the clock to design the ventilators from scratch.” It blows my mind. Everybody now, instead of cooperating, tries to design a perfect ventilator.
Dyson's core business and knowledge involves small devices which move and filter air, often on battery power (yes, I'm simplifying!). So designing something that reuses their existing technology with minimal retooling of the factory might well be easier and quicker than adapting their factory to an existing design.
