A question in regards to how generators work...

Hi everyone. My question is this:

Lets say you have a shaft. This shaft rotates at a relatively constant speed and does so with a large amount of torque. Let’s say I were to connect this to a generator that harnesses this rotation and converts it to electricity which is then stored in a battery. Could I then attach 10 more generators to this same shaft and create 10 times the electric output? Sorry if this is a silly question, but I have an idea and it heavily relies on using multiple generators to actually be worth anything. Please let me know if you need any supporting details to make an informed answer.

Thanks
