Actually, designing a plane with two huge 100,000 hp turbines, is rather stupid, because the plane has to be able to takeoff if one turbine fails, so if you use three 50,000 hp turbines and one fails it takes off the same as if one of two 100,000 hp turbines fail. Turbines are inefficient when operating at low speed (unlike piston engines), so using two turbines at low capacity after take off is less efficient than stopping one of three turbines and using the other two at 85% capacity.
With all due respect, you have no idea what you are talking about. Why do you think airlines prefer, and major manufacturers create, huge twin jets like the Boeing 777 and Airbus A-300?
They are much more efficient and economical to operate than 3 or 4 engine jets. The DC-10, MD-11, L-1011 are all pretty much dead, taken out of service.
