We may still need them for trucks and locomotives.

. . . and for high performance sports cars, racing, etc.

Though paradigm shifts come out of nowhere, we seem to be a long way from abandoning ICEs.

CvK just gave some more insight into his work on pneumatically actuated camless engines in a recent issue of evo:


CvK: Rather than producing electricity through brake regeneration, our technology allows us to turn the engine into an air pump under braking. This air pressurizes a 40-litre carbonfibre air tank at up to 20bar. We then release this air for extra performance by either adding boost to the engine or by powering the car in the city without using any fuel [,by using the engine as an air pump in reverse]. This size of tank is enough to power the car for up to two kilometres.

I really like Airbrid because air is free and doesn't wear out, making it a much better solution than using heavy batteries.

He does away with the need for an air pump as well as a larger battery and alternator, which addresses the claim that he was exaggerating potential efficiency gains because he wasn't factoring in the need for all this equipment.
(Advanced prototypes will be run on a fleet of buses.)
