Ok, that's pretty cool. Why hasn't this idea been come up with before - I mean, where are the car companies' research funds going?! If it works well enough, it could be pretty sweet, and might even make alternative fuels easier to deploy - hydrogen, for example.

This doesn't make any sense... how do they direct the force of the ignited gas to only one direction? Wouldn't the explosion provide an equal torque clockwise and counterclockwise thus keeping the turning stationary?
No, the curves in the channels create vectored emissions. Think of how a wind-turbine works, or a water turbine. Similar idea.

I'm not a mechanical engineer, but I suppose it's possible that a drive shaft could also be attached to this engine to eventually transfer the energy to the wheels of a car. What's not clear is whether this shockwave engine will produce enough torque to start a heavy car moving from 0 mph, but hopefully the reduced weight of the vehicle would make that possible.
It's about powering hybrid vehicles - the idea being you use it as a generator (he says 25kW, apparently suitable for a utility or goods vehicle though I'm not sure of that) to burn your fuel more efficiently than a traditional engine does, for the purposes of generating electricity that would then be used to drive the electric motors that actually make the vehicle go. Not as a direct driver of the wheels itself. I think an aspect of this system is that it generates little torque - problematic if you're trying to shift a heavy vehicle, but fine for spinning magnets in coils!
