sorry to bump this thread.. but i just need to say in response to all this. nothing is impossible. when i say that, i'm not talking about humans. humans may never achieve perpetual motion. but that does not mean it is not possible. just take a moment to think of our small planet. there are quite a few anomalies right under our noses. now broaden your view to our small solar system. compare that with the galaxy. and the galaxy with the universe. and the universe quite possibly among OTHER universes (though not yet proven). there is so much out there that we could never dream of. so many materials that we don't know exist. materials that may have very special properties. how do you explain every exception to the laws of thermodynamics?... now tell me that anything is impossible. laws are made to be broken. the 3 laws of thermodynamics were made based on observation and conclusions drawn from those observations. how can we state that anything is impossible simply b/c these laws state that its not possible. we haven't even scratched the surface on true science. i'm not saying that perpetual motion is possible. i'm merely making it clear that you can't just say something is impossible based on the laws of thermodynamics(which again are simply OUR conclusions on OUR observations[which have been very limited]).
**these laws were made so that we could progress and advance in understanding of the way our physical universe acts; not so that we exclude ANYTHING and EVERYTHING that doesn't fit into our definition of the universe. they should be expanded or even changed as we learn more about everything.
The laws of thermodynamics have stood up to about
one hundred and fifty years of experiments. I think this page [http://www.projectrho.com/rocket/thermodynamics.php] is relevant, along with this one [http://www.projectrho.com/rocket/respectscience.php], and this picture:
People have been trying to skirt the laws of thermodynamics for decades. Nobody's even come close to anything legitimate.
