A while back I tried to imagine what a plan for the city of Zion would be like if we were imagining a great city instead of Joseph Smith’s town of 10,000.
I only got as far temples topping the skyline and little rivulets of water running down the skyscraper sides to water the balcony gardens. But I wasn’t thinking hard enough. I never even thought of vertical farming and rooftop windscrews. They should have been obvious. The only remaining question is whether each ward/residential-tower will have its own couple of floors of farm, or whether several stakes will club together for a joint vertical welfare farm. Either way, at a billion bucks or so a pop for each farm, we’ll have to bring back local member contributions to the building budget. When you see the doorman at Woodruff Towers holding a cake-sale sign, you know the WT Ward hydroponic pump is on the blink again.
Vertical farming probably isn’t practical, and as with Joseph Smith’s original plat, the idea isn’t to come up with a rigid plan for a city that can be followed to the letter if ever put into practice. The idea is to come up with an ideal. That being the case, vertical farming as described in the linked article doesn’t fit. Its too complex and technical and roboticized and in Zion there can be specialists everywhere but everyone still needs to be able to get their hands dirty, or wet if you’re using hydroponics.
