Obviously technologies that are sustainable are a logical first step to creating a just society, one that doesn't trample life in all its forms, whether it's other humans or other life forms on the earth, one that acknowledges that we're all sharing the space and that there needs to be room for every living thing somewhere.

Not only is New York City the nation's melting pot, it is also the casserole, the chafing dish and the charcoal grill.

I try to build the things so that they're fairly indestructible. I've learned from my mistakes and some of those units, even if human life disappears from the planet, will still be recognizable a thousand years from now abandoned somewhere in the woods.

I like the analogy that the way that we live in Western Society, the energy that we consume in the form of fossil fuels, is the energy equivalent in pre-fossil fuel terms of having 500 slaves.

Technology tends to fuel the imagination. People with a technological bent can get excited by sometimes the most hazardous technologies, if they think they can harness them safely.

Technology has to be accessible otherwise it enslaves us, and I'm not really in favour of that.
