Could hydroponic farms reasonably feed 100 billion people?

I really think that we can feed way more than our current population using more advanced farming IF WE FIND A WAY TO PRODUCE CHEAP RENEWABLE ENERGY.

The solution would be hydroponic vertical farms. If energy is cheap enough lots of new possibilities emerge.

You could create a 100 floor high skyscraper next to the coast.

-freshwater would be made out of saltwater by evaporation

-artificial lights would simulate sunlight on each floor

-minerals would be extracted from seawater or from the earth's crust

-everything is operated by robots in the farm

-electricity is provided by a solar farm or a fusion reactor

Suddenly arable land and water are not an issue anymore. You have 100x more farmable land. With this technology, feeding 10x the current earth's population seems doable.

Would this work on a larger scale to feed 100 billion humans?
