> Otherwise it's behold, we found a high-resistance path for our battery to run a light bulb. It's like a nano Rube Goldberg! Paper is here btw: https://arxiv.org/abs/2002.09947

Only in the load resistor. Electron flux in the graphene membrane appears to be solely due to geometry. This curvature does not necessarily need to be buckled via heat energy. It could be mechanical or electrical, if I understand things correctly... More detail in this video clip with UArk's Paul Thibado: https://www.youtube.com/watch?v=wrleMqm3HiU I think what this research opens up is the possibility of "optimal" harvesting. There is some resonant frequency, some circuit configuration yet to be discovered that is perhaps self-sustaining. They've chosen "stochastic thermodynamical" circuits…

I'm not sure that I understand either. From the abstract (which phys.org failed to link to): > The system reaches thermal equilibrium and the rates of heat, work, and entropy production tend quickly to zero. However, there is power generated by graphene which is equal to the power dissipated by the load resistor. Looks like the article is also on ArXiV: https://arxiv.org/abs/2002.09947 https://scholar.google.com/scholar?oi=bibs&hl=en&cluster=103... Is it really a closed system at equilibrium?
