The future of fuel-to-energy efficiency is bright! Thermoelectrics could help capture more energy from waste heat and things like solid oxide fuel cells or companies like Lightcell energy might squeeze more energy out of fuels.

Thanks for sharing! So I imagine we could add these devices to a Combined Cycle system and squeeze more electricity of out them? Any idea how much we could improve overall efficiency?

Yes thermoelectrics could be added directly to the plant to try to squeeze more energy out of the waste heat. Currently they have been struggling with high costs relative to the energy they can produce, but I haven't kept up with the field recently.

For the solid oxide fuel cells and Lightcells these are presented as replacements to traditional power plants. Though often as smaller units that could power planes, or drones. I'm not sure what the efficiency is expected to be at power-plant scale.
