Simple, right?. The system was successfully tested last year by Dutch company Ockels and the two short films on its web site give a nice visual demonstration.
7. Whalepower
Inspired by the flippers of humpback whales, this technology will essentially serrate the sharp edge of wind turbines in order to lessen the already-small survival chances of skydivers who hit them.
