Hydrokinetics Gone Awry

When I came across the meme at left, I was instantly reminded of a guy who called me from Baltimore, MD about 15 years ago, anxious for me to hunt up investors in an invention he had created.  I was having a hard time understanding the concept he was describing, and so he told me, “Think of it as a river in a box.”

“Ah! Now I get it. You have a box full of standing water. You add energy to it to get it moving, and then our extract energy from the moving water.  And you think that you can extract more energy than you put into it.”

“Yes!” he said excitedly.

I calmly told him that this violates the laws of physics, specifically the first and second laws of thermodynamics, but he wasn’t “having it.” I wished him a pleasant good night and asked him to let me know when he had built a working prototype.

I’m still hoping to hear from him again.
