So when you see a regulation against lead, because lead is a bad in a regulators mind, what does that mean? You are not telling us what is good, you are just tell us what you don't want, not what you do want.

The problem carbon is that everyone thinks we have an energy problem, we don't. We have plenty of energy. We have a carbon problem. Carbon is a material, so we have a material problem, not an energy problem.

To eliminate the concept of waste means to design things-products, packaging, and systems-from the very beginning on the understanding that waste does not exist.

We are proposing buildings that, like trees, are net energy exporters, produce more energy than they consume, accrue and store solar energy, and purify their own waste, water and release it slowly in a purer form.

Don't get me wrong: I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes. And it's wireless!

In planetary terms, we're all downstream.

Here's where redesign begins in earnest, where we stop trying to be less bad and we start figuring out how to be good.
