One of the best ideas into the Global Ideas Bank for a long time today, one of those ideas that makes you wish you'd thought of it:
This suggestion, from Gary Emenitove in the US, hopes to turn a negative and irritating process (standing in a security line, being searched etc) into something positive. He points out that:
"In airports, we are asked to empty our pockets of all metal objects before going through airport security. This often results in a handful of pocket change.... At each security line there could be a collection device where people could put their spare change while emptying pockets. The collection would be regularly emptied and given to local charities."
Like all the best social inventions, this is inventive but extremely simple, and could be put into place with little cost: which airport will put it into place first?
