The objections DanielBMarkham are raising are literally high-school physics issues. I'm not expecting a QM explanation of what's going on, at this stage the researchers may not even be totally clear, but we know the efficiency is going to be bounded by thermodynamics, and in particular "generating electricity from waste heat!" rates dangerously high on the Science Bullshit-O-Meter. It can be done, but the bounds on efficiency are pretty dismal.

I'm not asking for a physics PhD level of coverage, but if you're going to cover this sort of thing giving us at least a high-school level of coverage would be nice. Just segment it off so those who are somehow interested in this but lack even that low bar of knowledge don't get too confused.

... or... not. I honestly can't say with a straight face this would increase your reader count, or any other interesting metric like that.
