I found this really interesting, thanks. It reminded me of a project I saw recently about purchasing tiny batteries to charge your mobile phone: http://www.huhmagazine.co.uk/8202/tiny-recyclable-batteries-for-your-smartphone Seems that a more suitable solution to that problem would be as you have outlined above, rather than creating something new, probably with exactly the same issue of unused energy.
Love this, had never seen it before. The chap in the video makes an interesting point about it being so difficult to communicate such a simple concept to the powers-that-be. There could be a simple communication resolution here that could have impact.
Yeah this looks amazing to me too! I love that the design is so lightweight—it's almost portable. It could be good for temporary or nomadic style living. Wondering about the longevity of the design. It doesn't look very sturdy, maybe it's difficult to use for long-term applications. But still a really interesting concept. I had never seen this before.
