TBF you'd probably get even more benefit from de-bloating that PC then. Free up some processing power for the tasks you actually want, instead of doing Microsofts bidding in the background all the time.
But we've all got different plans/priorities/timelines. Best of luck to you m8!
I never understood why this wasn't more common already. Most calculators I've run into are solar powered; but I've almost never seen tv remotes, timers, thermometers/humidity meters, or other similar devices with solar cells powering them.
Why not? Seems like an obvious solution...
