That would be most impressive, but I think you made a 3 orders of magnitude slip up. Hydro-Quebec only claims a capacity of 37.2GW.

yeh, 40TW would be close to four times the global capacity ...

Youtuber Marty-T in New Zealand has a few videos on his channel about using a rewired old washing machine motor for water generated power.

Not only that but they do not have water wheels at all, they have dams and turbines.
