Solar lamps have been around for 25 years but recently a company adapted them to deal with a new modern problem. Today where the vast majority of countries (including developing countries) have excellent cellular coverage Sunlite’s solar lamp modified their solar lamps to not only provide light but also charge mobile phones. The new Sunlite lamps contain batteries which now last for around 6 years so they can continue to function as useful tools even after the emergency passes. These lamps where used extremely effectively in the recent conflict in Iraq where 90% of the displaced refugee population had mobile phones but were unable to charge them. Sunlite’s product allowed Iraqi's to have the much needed light but also provided them the ability to charge their phones and call for help even in very remote regions. I find the hacking, moding or upgrading of readily available current technology very interesting.
