Initial upfront costs are heavy but you would be saving all of the transport and logistics costs for the lifetime of the facility. Aeroponics are also a lot less resource intense than growing in the dirt.
Has anyone broken down the difference in energy between artificially creating growing conditions in the middle of cities compared to just transporting the food from where it grows easily? Trains and ships which transport most food are incredibly energy efficient per ton transported
Trains can transport one ton of goods 470 miles on one gallon of fuel and ships can transport one ton of goods 600 miles on one gallon of fuel. If a urban farm can produce one ton of food it needs to consume less than a few gallons of fuel's worth of energy in lighting and other city-specific infrastructure in order to come out ahead of growing food where it grows best
Not in energy requirements when the sun is free and electricity and lightbulbs are not.
Transporting food halfway across the world ain't free either.
Absolutely. Doesn't change my point. Just brings up a different one.
Especially for some crops, like leafy greens. Having a semi-sterile environment can also mean pesticide-free crops. (Or at least, that's my understanding).
Way less water use and transport costs for a superior (fresher, pesticide-free) product.
It only makes sense for some crops, though. Ain't nobody growing watermelons or carrots in urban vertical farms.
