Use the internet to create a school in a box and have it printed in high volume by the nearest newspaper or paperback publisher.
H.G. Wells proposed the idea of a school in a box in the 1920's to be published by a central publishing authority. The internet makes it possible to collect large numbers of pictures and textual material, lesson plans, instructions etc. at very low cost which could be transmitted by satellite to a the nearest printing press. However, internet cloud contents can be lost and internet access is not always assured. Print lasts at least for several decades. Possibly work with UNESCO using UNL? Downloadable modules? DVDs??
