Hi, neolog! I lead the solar/low-power OS group. The picture in the article is from a Samsung NC215S from 2011, though few, if any laptops have been made to run solar. I am researching ways to use microcontrollers to run a limited form of linux as well as drive a basic e-ink display like a solar calculator, rather than long recharging times as in the Samsung, which used an Atom cpu. In this video I was able to power a microcontroller on just indoor light: https://www.youtube.com/watch?v=0ztj_MDNRcI
I've tried to put together a laptop with a solar panel, but of course it is not yet practical: https://www.raspberrypi.org/forums/viewtopic.php?p=1784621#p...
