One of the cool things about this engine is that it can run on hydrogen with minimal modifications. Not sure if the article mentions this, I don't have time to

  Have you looked at hydrogen prices? when the first hydrogen cars came out it was about $17/kg, and I think last time I looked it was around $33. I think that's a LOT more expensive than gasoline per mile.

    Meh, market forces can go either way. By the time green hydrogen actually becomes available it might have changed again. The problem is more finding a less lossy way to create it out of water with electricity. Also I don't advocate hydrogen as a 'solution'. To me the solution is less cars and nmuch better public transport. I could see it work for buses though.

  Why would you burn hydrogen in a car? It's more efficient to burn it in a power plant and run the car on electricity.

    I'm sure there's some niche uses where it makes sense. Fast refueling for example because batteries are so slow. And much heavier than a Wankel engine plus hydrogen tank. Like in a public transport bus that needs to be on the go all day. In fact I'm pretty sure that's what the hydrogen buses in my city do, they're way too noisy to be fuel cell electric. Besides, if you can run on electric you can bypass the whole hydrogen step altogether.
