There are many different solutions and features included for solar powered lights these days. Some of them include a radio but most include the usual cell phone charger and the LED lights. One of the most promising feature though I believe would be the development of a combined solar lantern and a wifi hotspot. The idea was to have a connection to the Internet by 3G. To this idea I would like to add the possibility of offline content. What if you can fit the whole school curriculum in the form of a digital content server onto these lanterns or solar kits. Streaming videos would be done by wifi directly from the device. No Internet required. With this you get the IT benefits right away before there is a Internet connection available in your price range. Another idea would be to have a wifi TV server. Where the device picks up the TV signal and streams the channels over the wifi to your phone or tablet.
On a further note. I believe one can make something of an emergency communications station with the solar wifi lantern. Inspired by the goTenna. It should be possible to add a low frequency long range antenna to the lantern and connect it to the phone through wifi. Communication is done with text messages on a built in web server. With this you should be able to connect two or more lanterns from friends and family and also get information from the government.
