What a strange fellow you are. One minute you're recommending feet of
insulation to save pennies in energy, and next your saying how wonderful a
woefully inefficient IC engine design is.

Rotary engines are used in planes, helicopters and
other applications.

They will have applications where size and weight is important, but fuel
efficiency isn't. Although with any aircraft, the weight of the fuel
needed for any given distance would count against it.

the Russians have a twin rotary engine helicopter.

The *Russians*? Well, they're certainly at the forefront of technology in
things aeronautical. Is it made by Lada?

Because an industry that scorns advancement does not use it, the car
industry, does not mean it is not viable.

You really are a fool. Billions have been spent trying to make a rotary
engine efficient. And they've failed.
