I love capturing as much energy as possible. I am all solar so if I don't use it, it gets wasted. So every little bit matters to me. What is a bitaxe?

Also if we start thinking in terms of sats spent on energy, with the energy use of a laptop or nuc pc, one can build a node with a rpi4 or odroid that consumes like 2-6 watts and add a bitaxe for the extra eenergy to earn more sats. It may not make sense for a first world person, but in africa and other poor regions where energy is scarce it may.

That makes sense. I am off-grid so low power usage is a big deal.

is my old laptop good enough to run a lightweight node?

It's my bias, I just like arm SBC, the advantages are that they consume much less energy, are very small especially those with ssd m2 support like odroids.
