Yes. I was thinking of the old steam locomotives and the immense amounts of thick black smoke they produced from all the coal they burned to produce the steam. Is there a more environmentally-friendly way to produce steam that's economically viable as well? And what about safety? Could auto collisions release life-and-limb endangering amounts of steam?
