What I want to know is, how much energy was used to create these floors, install them, and how much energy will be required to service them (the electronics) if they break down over the useful life of the installation, including how much energy was spent on resource extraction and processing.

Then I want to see that number compared as a ratio to the amount of energy these floors can generate over their expected useful life span, say 15 years in high pedestrian traffic areas.

I am highly skeptical that the ratio would even approach 1:1, I expect a net energy loss. But I could be convinced otherwise with some good data.

“The researchers say that this method can produce a lot of watts relative to the surface area of the generator, with the proof-of-concept device generating around 10 watts per square meter in early experiments. They claim that theoretical estimates indicate up to 10 kW might be possible.”

Ummm, anywhere between fuck all and an unrealistic amount.

I’ve got to think this is why they aren’t more popular. It’s very unlikely they are efficient enough when the entire process is accounted for to produce more energy than was put in to create the overall system. I’ve heard about these occasionally for years, and if it was anything more than a gimmick I would have expected them to proliferate by now.
