Anyone tried a radiant panel for engine pre-heat?
Been thinking of a radiant panel on the garage floor to warm my EV battery pack, and it seems the same approach could help an engine. Radiant panel(s) should provide more uniform heat distribution while also taking away the need to manually plug in, and allow heating of the transmission. (Yes, plugless connections are heresy for an EV advocate, but why plug in if you can do better without!) Your parking spot would need to be narrow enough to prevent tires from hitting the panel, but the panel could also be activated by either blocking a light beam, or completing the circuit with a pressure plate.
Of course, there are smart-phone enabled remote switches that could also handle the morning warmup schedule now. Lastly, it keeps things simpler onboard the vehicle, WRT extra wiring, weight, and potential for leaks.
