I'm generally looking for more industrial uses, or ones that can generate some revenue while not being crazy overhead. Farm related uses would best, and I have done a deep dive into fertilizer production which could be viable. And where I live, crushed aggregate is often used as a base for new greenhouse or shade house installs.

Basically, I already have a potential agrovoltaics solution that I can do with the shade, which infact requires significant shade, but where it's cheap enough to build this kind of system, there ain't a huge amount of grid infrastructure, so it would be better to use the power in place. I was thinking rock crushers/ aggregate production because it's something that depending on if the project is grid connected or not and depending on what the power company is willing to pay, could create aggregate or sell the power directly.

I really don't want to support crypto but unfortunately, as a plug and pay solution, it's a pretty easy and direct one.

Other ideas we've tossed around are refrigeration and food preservation, but the problem with those is that they need the power when they need the power, and so it's not exactly a way to sink excess supply.

It's tough because the overhead demands of any additional power sink almost always require 24 hours operation. Basically, the cost of a system to do "something" with your extra power is almost always such that you should probably just be running it 24/7.

Still open to more ideas but it will need to be able to pay for itself for me to get people on board.
