So, if one could construct the guts of a cell phone so that it would naturally disappear or dissolve in ground water in an environmentally benign way, that would be a fantastic thing.\"\u003cbr/\u003eRogers believes slowing down development to incorporate recycling is the wrong way to solve the problem, he argues the best way would be to create a response which makes the problems vanish by simply dissolving away.\u003cbr/\u003eHe says: \"It's essentially a challenge in materials. What kind of materials can you use that are water soluble, bio-compatible, environmentally benign, but still allow you to build a circuit that has a useful function?\"\u003cbr/\u003eOf course there is a gigantic leap from creating a small vanishing chip, to equally soluble mother boards capable of driving the sophisticated electronics which make our world.\u003cbr/\u003eBut Rogers argues that this is the direction to go saying: \"You don't need your cell phone to last for 25 or 50 years. Nobody wants to keep it that long anyway. The electronics will last that long, but it doesn't serve a purpose, and it's actually counterproductive because it forces you to recycle or deal with all the waste.
