I think I saw an apple A16 takes about 8 watts, which would be about a square foot of solar panel. So assuming we keep making progress it doesn’t seem insane to me that a laptop where the back of the lcd is a solar panel would be enough?

Angle though isn't ideal, unless the PV panel pops off the lid so you can position it better (and still be able to open the screen far enough back to read - though that's often not great in bright sun). I remember the OLPC could be run by hoisting a bucket of sand or water up on a rope and pulley on a tree branch and letting it drive a small generator as that came back down - and that was almost 20yr ago).

the mild inconvenience of needing to be in direct sun for N hours always overshadows this

you need a massive efficiency improvement to overcome this

we're still in the calculators and tv remotes level of on-device solar
