Metaphor time! What if you had a fire? You just want to use the piece of wood to make some heat, but you also get things like light, smoke, and ashes. So it's not really efficent. But with a sufficent knowledge of physics, we could reuse and recycle the stuff in the smoke, ashes, and light to make a new fire that produces even more heat! AND because the human body gives off as much heat as it gains from the fire over time, you can add that to, meaning you wind up with the same ingredients as you started with. So basically, you have a fire that goes on forever AND get to stay warm at the same time! Baiscally, my fire metaphor on a really small scale is theoretically possible. |
careful about the heat talks. environmentalists might use this as facts for global warming.
