Hydro is limited, there are just x rivers flowing with y water at z height.
You will NEVER be able to supply the whole world with hydro
So it's obvious that the only thing left was exactly the solar thing YOU mentioned first..... 3 times
just Y water is not a problem...
heres your problem.. screw it ill draw it for you
(imagining a its a year later... and had a year drought you'll se an empty reservoir, right)
heres my solution
its called re-use.. recycle. after all if you can pee out of your urethra to turn a paper windmill. does the water vanish.
if you direct it right and your standing above a container. the container is now a new bladder.
now pour that over a paper windmill... now i should have sparked your imagination positively
repeat repeat repeat
water turbines are not a one use and its gone forever..... Y water is not a problem
as for z height to have space/capacity for a second bladder/reservoir. well it doesnt need to be a container of a years supply of rain/pee..
so
so now as of day 3.. the same water that fills the main reservoir gets reused 3 times.
production: so thats 3x electrical production
capacity: reservoir + 2x 0.003~ of a reservoir to hold and reuse the same water twice to get the 3x production
Oh my god, you've just invented the Perpetuum mobile!!!
We can build 100 dams and from a single river, we will have infinite energy....
Of course, if we exclude the fact that the Colorado River, for example, has only a 270m drop from the Hoover Dam till the Ocean and the dam itself stand 160 m on top of the water level before the drop. .
And the pee example.....
Have you calculated if you can produce enough energy with your urine to lift a bottle of water so you can drink it?
On the energy required to lift your body up so you can actually pee?
Common Franky, what's next? Flat earth?
