I love this – http://huff.to/eLbiZN – This makes me feel positive about the future when such a lot of other things don’t. It shows the essential ability of humans to think through clever solutions for problems if they put their minds to it. Perhaps if we all spent more time thinking about such solutions rather chasing fame, fortune or meaningless rubbish??? I wonder if Spain’s economy would be in such a hole if it had focussed on clean energy rather than building ever more apartment buildings on a speculative basis that were not needed and couldn’t be afforded???
