Speaking of that…Texas has a plan that I’m currently on where the juice is free 9PM to 6AM. I seriously thought to find an auction where a datacenter style “whole rack of batteries” is being liquidated and pick one of those up.
Charge the batteries at night, run servers on grid at night and on batteries in daytime.
A fully loaded liquidated UPS (look up Galaxy 3500 for example) goes for about $10k, while you might get lucky at a gov’t auction to find one around $3k ~ $5k fully loaded with batteries, so ROI is rather steep…
…but first, I just want to put together my very first rig that is not my laptop. My 8 core CPU macbook pro churns 56 Kh/s. While impressive by my own standards, ain’t gonna cut it in a real world mining effort.
