Numerical investigation of the convection heat transfer driven by airflows in underground tunnels - ScienceDirect
Using subway tunnels as the heat source in a ground source heat pump setup for district heating maybe. I suppose that's one solution to the London Underground overheating problem...

Foodtech | Induction Food Systems | United States
Similar to microwave based on-demand water heaters, this uses a heating element suspended in a pipe, heated by an external induction coil. Useful for flash pasteurization and heat processing of liquids and liquefied foods. Apparently less energy consuming compared to steam pasteurization.

So they are directly running electricity through the water, via a dynamically controlled array of graphite electrodes to manage the resistance in the circuit, to ohmicly heat the water on demand. They have guard ground electrodes to keep the thing from electrocuting you downstream.

Fluoride Salt-Cooled High Temperature Reactor (FHR) Project | CANES
Don't like the pebble fuel, but this is probably a more achievable NACC configuration, as it isolates secondary loop better in case of primary loop leaks, compared to other proposed NACC systems, which use helium gas reactor, with a helium turbine within containment driving an external air compressor also in containment sucking in and then expelling external air through containment which isn't good (which I suppose that might be solvable with a shaft through the containment wall with frangible clutches).

ACT-RPR-NPS-1107-NTER-paper-final - ACT-RPR-PRO-1107-LS-NTER.pdf
NTER, a nuclear thermal electric rocket design. Uses LH2 propellant to cool a helium brayton cycle turbine fed by a NTR that heats hydrogen and helium, then tries to supercharge the supersonic nozzle exhaust with an induction loop (which seems to require cesium seeding in the exhaust??). Also has optional oxygen feed, to emulate LANTRN. Seems like you could do better with the NTR feeding a VASIMR though...

A semi-portable consumer version of those pizza delivery warmer bags. Note it seems to use AC power, so no cigarette lighter DC. It might be able to actually cook, like a slow cooker, but I doubt it gets sufficiently hot enough for most foods to cook from a raw state.

daikinaltherma-brochure.pdf (application/pdf Object)
Getting closer to the ideal home energy management system, this using air sourced heat pumps boosted with solar thermal panels, driving a hot water heater as well as in floor heat transfer loops or traditional radiators, or heat exchangers for forced air HVAC. Now boost this with an HRV, integrated solar PV thermal panels providing heat and electricity, as well as an external fuel cell supplying heat and electricity, a cold thermal storage tank (nighttime ice generation) as a pair to the hot water tank, and a home electrical storage battery, and then you have something awesome.

The Prometheus Gas Turbine Project Introduces A New Electric Gas Turbine
Is this for real? Something fishy about this (okay, yes, diesels have a better SFC than gas turbines), since this doesn't seem to be a special case of a generic turbocharged diesel. There have been direct compound piston diesel gas turbine hybrids before (turbo-compound) in aviation, and a terrestrial version could easily include electric reheat of the diesel exhaust before turbine entry to emulate this concept. I suppose decoupling the diesel from the compressor/turbine (turbocharger) stack via electricity gets over the mass flow limits of the diesel. In some ways this is similar to the newer electric assist turbochargers, which can function in both motor and generator modes (generator mode limits turbo RPM to eliminate the need for a wastegate).
