Re: [Guide] How to run a Bitcoin Core full node for under 50 bucks!

Anyone ever tempted to run a node off a solar panel? I assume a single board computer would likely be the most realistic way of going about it.

Not..... yet! I plan to get something relatively large but still single panel that would easily power a node even on cloudy days.
The more ambitious part would be also developing a hashboard that is then dynamically powered on / off depending on sun availability. Mainly to show the counterintuitive concept of harvesting otherwise 'lost' energy (since the solar panel will produce much more than what a little pi needs on sunny days) and therefore run not only carbon-neutral, but you could argue carbon-negative mining. Wink

I would disagree it's carbon-negative. You need to consider carbon footprint during production[1] and whether it's recyclable after the panel reached end of life/broken[2].

Well, my point is that without the hashboard, the same solar cell that runs your node, actually produces more power than needed most of the time (to be able to get through the shortest days of the year). So adding a hashboard uses this otherwise wasted energy; there is no need to manufacture and recycle more solar cells, the only extra hardware is the hashboard.
