2-Acre Vertical Farm Run By AI And Robots Out-Produces 720-Acre Flat Farm

...

 In recent years, farmers on flat farms have been using new tools for making farming better or easier. They’re using drones and robots to improve crop maintenance, while artificial intelligence is also on the rise, with over 1,600 startups and total investments reaching tens of billions of dollars. Plenty is one of those startups. However, flat farms still use a lot of water and land, while a Plenty vertical farm can produce the same quantity of fruits and vegetables as a 720-acre flat farm, but on only 2 acres!

Vertical farming exists because we want to grow the world’s capacity for fresh fruits and vegetables, and we know it’s necessary.

Plenty’s climate-controlled indoor farm has rows of plants growing vertically, hung from the ceiling. There are sun-mimicking LED lights shining on them, robots that move them around, and artificial intelligence (AI) managing all the variables of water, temperature, and light, and continually learning and optimizing how to grow bigger, faster, better crops. These futuristic features ensure every plant grows perfectly year-round. The conditions are so good that the farm produces 400 times more food per acre than an outdoor flat farm.

Storey said:

400X greater yield per acre of ground is not just an incremental improvement, and using almost two orders of magnitude less water is also critical in a time of increasing environmental stress and climate uncertainty. All of these are truly game-changers, but they’re not the only goals.

There is more.

The story does not provide a cost comparison with flatland farming.  The cost will certainly be different.  It will take different farm equipment and different energy sources.   The verticle farming can be done closer to markets saving on some transportation costs.
