In the year 2009, the year 2GreenEnergy was launched, the world of renewable energy had high hopes for the technology shown at left.  At the time, solar thermal had a huge advantage of competitive approached to clean power, in particular, the fact that the energy generated by the array was heat, and the storage of heat energy in huge vats of molten salt was extremely inexpensive, compared to the storage of electrical energy in batteries.

While the storage issue remains the case today, the cost of energy from solar PV and wind has sunk to the point that solar thermal is no longer competitive.

Renewable Energy Concepts Can’t Violate the Laws of Physics

In the early days of 2GreenEnergy, my people and I were vigorously engaged in finding solid ideas in cleantech that needed funding in order to move forward.

I vividly remember a conversation with a guy in Maryland who was trying to explain the (ostensible) breakthrough that he and his team had made in hydrokinetics. When I was having trouble visualizing what we was talking about, he asked me to “think of it as a river in a box.”

“Oh!” I exclaimed. “You mean you take a box full of standing water, add energy to it get it moving, then extract that energy, leaving you with more energy that you added to it.”

“Exactly.”

I politely explained that the laws of physics, specifically the first and second laws of thermodynamics, make this impossible.

He wasn’t through, however, and insisted that, in his office, his people had constructed a “working model.”

Here’s where my tone descended into something less than 100% polite. I told him that he may think he has a working model, but he’s wrong; if he believes this, he’s ignorant; if he doesn’t, but is conducting this conversation anyway, he’s a fraud.

“But don’t you want to come see it?” he implored.

“No. Not only would not fly across the country to see whatever it is you claim to have built, I wouldn’t walk across the street to a “working model” of something that is theoretically impossible.”

I tell this story because the claim made at the upper left is essentially identical.  You’re pumping water up out of a stream, and then claiming to extract more energy when the water flows back into the stream.

Of course, social media today is rife with complete crap like this.  We’ve devolved to a point where defrauding money out of idiots is rapidly replacing baseball as our national pastime.

Until recently, I would have moose, maple syrup, and frozen tundra.

Now I would say: decency, honesty, and class.
