Added a new interview link for Vinay Gupta

Vinay Gupta Tools To Not Die With: An Interview with Vinay Gupta, creator of the Hexayurt from BoingBoing. An important excerpt to take away:

Let me break that down: you take the sustainable harvest of the earth, and you take the share of that we’re allocating to humans, and then you divide by nine billion. So much carbon, so much steel, so much bamboo. It’s not quite that simple: some places are cold, other places rain a lot, but the basic framework is that we have to share the inputs the world generates nine billion ways. Right now we’re sharing them so badly that a billion of us are regularly hungry to the point where they get hunger diseases. Really that’s not OK. I know we all have our struggles, but this is not OK. So we have to fix this: design a good lifestyle which uses that amount of resources, and then adopt it.
