Renewable Energy and the Laws of Physics

Normally, I ignore emails like this one from “Yura,” but, for some reason, I got sucked in here.

Yura: I have a proposition for you: a generator that produces electricity only using the Earth’s gravity. My device has been experimentally tested. I need your help in organizing, designing the copyright, and marketing.

Craig: The U.S. Patent Office doesn’t grant protection for concepts that violate the laws of physics; you’ll have to look elsewhere.

Yura: I know about this.  But if you look in the future it will be the greatest deal. I need just some technical support and protection for my invention, because it works.

Craig: Can you send me something that suggests that what you’re saying is true?

Yura:  Let’s go this way. Send to me please concretely what you need to know about this and I will send to you answers. Understand me right; I will show you this invention only after a real proposition.

Craig: You need to realize that your claim makes no sense.  You could be saying that your machine spins straw into gold, or turns cats into dogs, and it would have the same level of credibility.  Millions of people have been trying for thousands of years to find an exception to the first and second laws of thermodynamics, to no avail.  That’s why they’re called “laws,” rather than “suggestions.”  If you turn out to be God’s chosen person whom He put on Earth to show us a new direction, I will apologize for giving you a hard time, but at this point I’m afraid I’ll need to see some proof.  Sorry.

If I hear back from Yura, I’ll post it as a comment.
