The first step is to offer them to university students , they probably have WIFI and electricity.

And yes, rural electrification is a huge challenge, but it's much easier to deploy a solar panel per school , to power some tens/hundreds of low power tablets.

They run on battery, no?

My bad. Downvote me to oblivion.

In a video about this tablet, the researcher behind it (or so I believe) said the goal is to have power-consumption be low enough to ultimately allow it to be solar-charged.
