In London recently the old mistreated red telephone boxes have been cleaned up and revamped into solar boxes that you can use to charge your phone, they have solar panels on the top so they are environmentally friendly and free to use. In return people will watch adverts while their phone charges.
It is a short term fix if your battery is running really low or if you are waiting for someone and you want give your phone a little boost of power. This was created by Some newly graduated students from the London school of economics.Also the boxes are cleaned often so that they don't get all vandalised.
I think that this a really great unique idea and will go down really well and be a great help to people, it's a nice creative way to stop the old telephone boxes being a waste of space. The adverts are also a really good way to pay for the maintenance of the solar boxes.
