Device wraps around hot surfaces, turns wasted heat to electricity

There are many industrial processes that produce large amounts of waste heat. Capturing some of that can make sense. But I guess unless you're retrofitting existing installations you get better efficiency with different solutions than wrapping stuff around a pipe.

But isn't that "waste" heat already used to heat the office building and other buildings nearby. So there is a use case already.

Of course during the year there are times, when heating is not needed. Then it would make sense to use the heat otherwise.

I think most industrial waste heat is indeed wasted. You don't tend to build for example chemical factories close to where you would have offices or homes.
