In post #45 we got back to efficiency and emissions briefly. I wanted to make sure that fhe full scope of emission control was considered as you develop this new automotive power technology.

The NOx catalysts developed so far, require a precise amount of oxygen and very hot exhaust. So, the reconfiguring of the O2 sensor and the warm (not hot) exhaust pipe makes me wonder if anyone has measured NOx on these super-efficient cars.

It's my understanding that NOx was the primary reason the horizon was brown most of the time in the 1970's and '80's.
