Since most schools in Bhutan do not have access to the Internet, or the access is painfully slow, viewing online lectures is usually impossible. Today, however, with unbelievably-cheap computing power, and thanks to projects such as KA-Lite (Khan Academy Offline), it is possible to avail the power of Khan Academy to any school in Bhutan.

One of Khan's thousands of videos,served offlineWe recently built a $99 Khan Academy wireless (and wired) server using a Raspberry Pi. The prototype server can serve more than 50 GB of Khan Academy content, and anyone with a PC, laptop, tablet or smartphone can connect to the server and watch the videos. In a school environment, such a server can also be used by teachers to track the progress of students

Kind of an amazing moment in the history of technology, actually.
