Gear Ratios / Mechanics

Hi, I was just wondering if one had a system of 2 different gear ratios to one output shaft.

For example: Two identical motors A and B rev at 1000 rpm and have a torque of 10Nm. These motors are geared

Can the frictional electricity produced during landing of a plane be used for constructive purposes?

As we know that in aeroplane during landing the charged produced in it due to the friction with ground are earthed through its wheels; can this charge be stored with the help of a capacitor and used
