The paradox of vertical farming

Artificial lighting saves land because plants can be grown above each other, but if the electricity for the lighting comes from solar panels, then the savings are canceled out by the land required to install the solar panels.

@neauoire In a city center with solar panels on roof tops and then centralized plant farms you may gain some efficiency.

The alternative being someone going up to every roof top to care for / harvest the plants?


@rune the alternative might be something like a garden on every roof yeah.

@neauoire I think it would be easier to get people to install solar panels than getting them to care for a garden (if one can even be setup on their roof).

I also think you can do it more efficiently if you centralize it a bit.

But I absolutely recognize that it complicates things and has some downsides.

@neauoire @rune or what about a solar collector/concentrator on a tall building that distributes into a farm within that same building underneath? 🤔
