In moto racing, they use tire warmer to keep tires hot when the tire is not running.
In particular weather conditions (e.g. heavy snow), aircraft require de-icing operation after staying parked for few tenth of minutes.
Do any device to protect the wings and other parts of the aircraft requiring to be free from ice before take off from icing and possibly keeping those parts above icing temperature exist? It could save some deicing time (and de-icing fluid) by reducing the amount of ice accumulated while the aircraft is on the ground.
EDIT: When asking the question, I was thinking of airliners between two legs in winter in Canada (with jetbridge connected, only few tenth of minutes before next scheduled leg, international airport ground support available,... and snow and icing conditions). I don't think the question should be restricited to this case, but it should take it into account.
