Since EVs drain more battery heating the cabin in winter but still need to keep the windows defrosted, how about defrost wires on the windshield, just like the rear window? Even the side windows?
Would that not be more electrically efficient?
Has it been done before?
Discuss!
Source: I keep seeing "tips" on maximising range by using the seat heaters instead of cabin HVAC. That works for about two minutes until the windows are fogged up. Not an option

@DenOfEarth as it happens I went to see a few EVs recently - Ford seem to have some kind of patent on "invisible" (near invisible) heating elements embedded directly into the front windscreen (possibly back too, would make sense)
So I guess, yes, it has been done, but Ford own the idea
@DenOfEarth it was just the EV Puma (Gen-E, is it?) ... although it was the showroom model so I guess it may have been an extra (which would probably make it above budget for us!)
I think it might be what they call "Quickclear"

Wow so it's been around for a while. The page says high current draw which I'm not surprised seeing as it's resistive wires, but using the rear defroster doesn't usually reduce the range calculation on my car unless duh it's simply hidden from the calculation? Someone needs to do some science on this... And it won't be me!
It also says the wires interfere with GPS and radio antennas so maybe that's one reason it hasn't been deployed more recently: mobile phones in the car.
