    Well technically if you shouted loud enough and long enough you could emit enough energy to melt down the wall if it was made of a meltable material like steel. Someone could probably do the maths.

      I did some quick dirty math and it seems screening at something produces 0.001 watts and to bring 1 kg of steel to melt you have to scream for over 23 years. But I’m certain that the loss of heat via radiation is probably more than 0.001 watts.
