Heated/Cooling door handles/moldings

Door handles can be hot or cold to the touch so heating or cooling them prior to entry would be nice. The door molding can also freeze shut at times due to moisture and by preheating them would eliminate this issue making access easier and protect the molding from tearing or wearing out prematurely. The use of photovoltaic cells placed in body panels on the roof could act as the energy source to not drain battery.
