Where did you find that? 110lbs for the turbines? You also forgot the 4 electric motors.

Motortrends link says 110lbs x 4 electric motors + 400lbs batteries = 840lbs before turbines and diesel fuel that will weigh around 100lbs with a full tank. Could easily weigh 1,200lbs before figuring in the transmission. The turbines are watercooled, so there will be a radiator.
Shoot, at least it is still getting 30mpg.

I expect the turbines are air cooled, just like every other turbine I know off.
Why do you and the other chap include fuel - you wouldn't worry about it with a 'convenjtional' engine.

Red, service intervals for turbines are very long, j7st make sure they have a good supply of clean oil - regarding a catastrophic failure, remember the mass is still very low and so containment is easy. Consider a turbo-charger failure, even a large model at over 100k rpm does little damage.

Thing I would be concerned about would be the potential noise levels...
