Dyson is spending $1.34 billion to develop a “radical” electric car: the company already has 400 engineers dedicated to its car project, which has been working in secret for the past two-and-a-half years. While most companies are using lithium-ion batteries in their current models, Dyson said its car would use solid-state batteries that are smaller, more efficient, easier to charge, and potentially easier to recycle. Will they turn out looking like their vacuums? Dyson said his electric car would be “radically different” than those being designed by other car makers, including Tesla. “There’s no point doing something that looks like everyone else’s,” he said. “It is not a sports car and not a very cheap car.” He said he hopes the vehicle will be just the first of a line of electric vehicles from Dyson and predicted that within a few years electric cars would be the largest source of revenue for the company, eclipsing its existing products.
