So an electric car might hold 100 kWh. To charge that in 1 minute you would need 6000 kW of power, or 6 MW. Typical “rapid” chargers today do 350 kW and these are the kind that are difficult to find. A nuclear plant makes around 1,000 MW so if you had 166 cars charging at once you would overload one.

Never mind phones, what about cars?

Yeah but I doubt that’s actually the case based on the physics involved. We need fast charging cars way more than fast charging phones.

Why do you feel that the researchers are wrong about their physics research?

The researchers who wrote the paper only mentioned possibly applying the tech to very small things like wearables and Iot applications where a large capacitor might be relevant. It’s the journalist summarizing it that makes the wild claims about phones and cars, which don’t tend to use capacitors for a bunch of reasons, not least of which is that they tend to be physically twenty times larger than a given battery of the same capacity.
If people are able to deal with batteries anywhere near that large, then I’d imagine most of them would choose twenty times the battery life/ range over being able to charge fast enough overload a wall outlet/ small power plant.
