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.
[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.
