I love inventions that are cases of simple, elegant, lateral thinking. Charged with finding a way to connect the millions of people worldwide in remote areas to the internet, Google have launched (literally) Project Loon. The idea is so simple and charming - launch a flotilla (if that's the right word?) of balloons into the stratosphere and have them carry transmitters to create a network of coverage. A sort of sub-orbital, wind blown, satellite network. Magic! I have to say that the video is also one of the most creative I've seen recently. Enjoy!
