Most of the time the IC engine will be running at a lower, more
economical setting. Which is probably wide-open throttle, peak torque
until the battery is full - then stopped for a bit. Repeat until
journey's end.

The most economic setting for any IC engine is usually in the range
65%-75% of maximum power.

This Yo-Mobile engine not like any other engine you have known, it is a
"rotary vane engine". It is also tuned to turn a genny.

Despite the claims, it is not a new concept, merely a new version of an
old idea. A major problem in the past has always been vibration, due to
the variable rotational speed of the vanes.
