Venkat Viswanathan thinks there’s a “straight shot” from today to the technologies needed to build that future, despite all the jokes about flying cars being fantasy. The professor at Carnegie Mellon University is obsessed with building the batteries that will power these zero-emission aircraft…

Viswanathan has worked with next-generation battery companies such as QuantumScape Corp., 24M Technologies Inc., and Aionics Inc., and concluded that aviation is “the most important problem that batteries can address,” he told the Zero podcast…

The problem is that it’s hard to beat jet fuel when it comes to the right combination of weight and power needed to lift a plane (with passengers and cargo) off the ground. To make a battery that is powerful but light enough to accomplish the same feat is bound to be extremely expensive.

That’s why Viswanathan believes the first application will have to be in the luxury market.
