I think that cheap laptops, or even cheap desktops, run by batteries charged by solar/crank energy, with access to the Internet are an extremely desireable tool for the education of humans everywhere.
Using satellites, it should be possible to provide Web access to most of the planet, especially to the areas where a majority of the people live. For example, access to Wi-Fi in Reno, Las Vegas, along the Humboldt and around Lake Tahoe would cover a majority of the people in Nevada. In Alaska, Fairbanks, Seward Peninsula, Juneau and Sitka would do this. The same is true of places such as Mongolia, Botswana and Rajastan.
