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.
So that’s what we’re trying to do, I think, we devotees who write about the designed and pen‐outlined world. We’re just wrapper‐uppers at Crate and Barrel. We’re packagers, temporary packagers. And our chosen packing medium—sentences, paragraphs—sometimes obscures as much as much as it helps us see.
