I don't really agree with the 'green' hype, and banking on battery improvements etc. However, I think designs like this will become useful along with other forms of drone technology. This helicopter actually looks fairly cheap to manufacture and maintain, and a 10 minute flight can easily be, for example, a hop across a river or over dense traffic as part of a daily commute, and it can stand and charge at each end.
