Machines generate waste heat when they do work for us. And this year, seven billion of us will use twenty‐five trillion kilowatt hours of electricity. An awful lot of that will end up as waste heat. So, we treat waste heat as a problem. We see it as a challenge to design how we can manage it. We don’t think of it as a resource. If we thought of it as a resource, that would be results we are just throwing away.
When I learned to farm mushrooms, I discovered to grow mushrooms you use agricultural waste that is available to all the poor families in any any place we can say this is a struggling country. As long as they practice some form of agriculture, they will have this kind of waste material.

In the future, we have to change the way we look at consumption. That’s why I’m such a big proponent of the sharing economy. Because it’s not an issue of if it’s going to happen, it’s when it’s going to happen.

[A]ll these hidden infrastructural and material costs go into the stuff that we just use very very quickly. We just kind of consume them, we don’t think about them, we just want to go on with our lives. When you start actually sort of picking away, looking at it all, you realize how shocking it is.
