Neat. Little bit frustrating that there was no input measurement. I strongly suspect you'd need very good insulation to make it viable.
Edit: Watched the freezer video. Performance is predictably bad, but not as awful as one would expect. Might actually be a viable daily driver with thick enough insulation or vacuum panels.
