In the fictional Back To The Future movie series Doc Brown invents a time travel machine powered by a fusion generator that uses garbage as fuel. Last October Netherlands-based giant Philips showed us the Microbial Home, an integrated cyclical ecosystem where each household function's output is another's input - all powered by waste. The future may actually be garbage powered after all.
Yes, it was just a concept, but a compelling one, based on science and elegantly executed. A steampunkish kitchen island that converts vegetable trimmings to methane gas that powers the lights, a terracotta and wood larder concept/ dining table that challenges our use of refrigeration and food storage, an awe-inspiring glass urban beehive shaped like a inverted drop of honey, and more (and for our other Back To The Future favorite, a lamp that uses the same maglev technology as this Hoverboard).
