I have a related problem. I’ve got a 1.3kW solar array at our cabin. When we’re not there, it generates way more power than the HVAC needs to keep the building at a healthy humidity - say 4-8kWh a day. There’s no grid to sell it back to, but I do have an LTE internet connection.
What to do with all that curtailed power? Crypto obviously, but it’s so dumb I’d rather dump the power into my ground rods.
If you had 8kWh of free power a day and an LTE modem, what would you do?
Maybe donate some processing time to a project like BOINC https://boinc.berkeley.edu/
Run one of those inefficient water-from-air gadgets. It’s power you were gonna waste anyway, might as well build up your stock of the wet stuff, or even send it to a small trough for the wildlife.
Maybe add a small greenhouse or hydroponic system? Might be fun to have a semi automated remote food system.
I know you ruled it out, but by mining crypto with your surplus clean energy you deprive other (potentially dirtier) miners of that same profit. It’s a pretty green choice to make.
Similar concept, although I think this one only uses a single panel and battery? https://solar.lowtechmagazine.com/
The Solar Protocol website cites Low Tech Magazine as inspiration. :) I find both facinating.
How does this handle old cached DNS entries pointing to servers that are lower on power? Or do we assume that TTLs are small enough and the amount of power left on lower-energy-available servers is enough to sustain until the TTL expires?
From where I am it looks like a 180-second TTL:

I have been planning a solar powered website project since finding the solar powered magazine a couple of years ago. This is taking it to the next level.
