I think you’re answering the wrong part of the question. We now know we have very little power, but can that be enough? Can we power some type of storage and adding new data with that. Maybe even a very simple display?

No backlights, no apps, no internet, no touchscreen, no formatting....basically it was a keyboard with a small amount of digital storage (RAM or flash, forget) and a tiny monochrome LCD to read what you were editing.

i seem to recall (some maybe cpl decades ago?) some hippy types attaching treadmills & bikes etc. to do just that by using that kinetic energy to turn a generator, producing electricity that's converted to AC power with an inverter to power devices or store in batteries.

same general principle hybrid cars use to capture the kinetic energy of the spinning car wheels when your foot's off the gas, & when it's braking. we waste so much of all this free energy by not capturing it! a lot of energy problems would be solved by exploiting the process.

totally as it should be! and shoulda been all along, frankly. heated with wood for almost 20 years, but we had to cut it ourselves. loved it! invigorating to be so productive.

That's plastic bubble keyboards though. at peak esports, esports guys were caught in a masculinity cycle over how clicky their mechanical keyboards were. what do I multiply this by, to account for the heaviest buckling-spring switches compared to the membrane boards from the study?

You've got two things to balance-one is that the solar production displaces other forms of energy, usually from heat engines. The other side is that solar panels have a lower albido than the surfaces they are covering, so less of the sunlight is reflected back to space. I think the latter dominates.

Your analysis failed to account for my mom, who in her prime could type 120 wpm on an entirely mechanical typewriter which required a substantial amount of kinetic energy for every keystroke. Just to depress the key, let alone give it an impact, required about a Newton-inch of work, maybe a lb-cm.
