I’m not imagining any problems. The difficulties I’ve outlined are genuine issues that have to be addressed. I think you’d be surprised to learn how much difference there is between a thing existing and it actually operating efficiently.
Vertical farming usually uses LED lighting, not direct sunlight.
That’s one method of bringing"sunlight" to plants. Another would be to grow them outside.
And I think the idea is that once the water is present on a given level it gets recirculated and reprocessed there, so it wouldn’t need much additional pumping.
Even if all you do is pump all the water from the floor of each level to the ceiling of the respective level, you’ve done the exact same amount of work as pumping all the water for the top floor back to the roof in the first place. Only you’ve done it with a hundred pumps and a hundred times the points of failure and repair rate as a single pump for the entire building.
You’d be so much farther ahead to just install a reservoir on the roof that gets filled by a single pump and let gravity feed the lower floors. Much the way we already do for flat farming.
And then you’ve got to make up for the inefficiencies lost in planting and harvesting. Vertical farming brings nothing to the table except a smaller footprint in a world where that’s not a real advantage.
A far better use of empty office buildings would be to convert much of the space into full-time living space.
The problem is a constant fight against gravity. You’ve still got to pump the water effectively to the top of the building every day. And there’s still the issue of getting sunlight to the plants.
The question really becomes whether it’s more economical to just use traditional irrigation techniques upstream and ship the produce in vs converting a skyscraper into a very inefficient farm space.
Maybe it’s because I am a native english speaker but your reply is offensive and embarrassing to native English speakers around the world. You can do better, America. You just have to try.
Maybe it’s because I am a native english speaker but I read this as a pledge to murder all homeless people by cutting them in half 🤔
It doesn’t work because, as pointed out by another commenter, wealth does not “trickle down”. It only accumulates. This has been demonstrated to be a basic function of wealth and the minute you begin to think about it, it becomes obvious that having more resources makes it easier to gather more resources.
They weren’t.

Maybe we shouldn’t be outing anyone. One’s personal sexuality isn’t anybody else’s business. Even if one is a bigot.
You would turn down free bread sticks and $7M? At least eat some bread sticks.
