This is a great video from those clever people at Ted.com, the speaker is David Sadoway who has been looking into what type of battery can be used to store renewable energy so that we can still make use of it even when the suns not out and the winds not blowing.
The video is a great insight into the potential future of renewable energy and is a great argument boost towards the realisation of renewable energy as a sustainable source of power for the future.
Possibly the most inspiring part of the talk is David’s willingness to think about these problems from a different perspective his philosophy is “We need to think about the problem differently. We need to think big. We need to think cheap.”
