Skeptical Re: Clean Energy Concept

From someone who found me online just now:

We propose our “Vapor Drive” Generator with these features: Patented Novel design of 25-50KW Generator- FEATURES: No Fossil fuel, No Emissions, Quiet -Operating expense $20/Month, Size of a 20Cu Ft Refrigerator designed for 20Yr life. Seek investment of $3-4 Million. Following mutual NDAs please request Executive Summary which further describes our Invention and request.

I respond:

Please send me some non-confidential info on it.

Come to think of it, why do you need investment capital?  Doing the math just now, I realize that you have a license to print money.  If you have one of these and it generates the low end of the range, 25 KW, $20/month means about 1/10th of a penny/KWh, which is about 1/100% of what Americans are paying right now.

If I had something like that, I wouldn’t dilute my profits selling equity.  I’d get a PPA (power purchase agreement) from a utility or a large power consumer, and sell them clean energy at a profit margin of well over 99%.  I’d use the incredible profit to build a second one, then double it to four, then eight, and so forth.  I’d be a billionaire long before my kids got out of school in June.

My wife has been wanting me to take the four of us and go on one of those high-end Viking River Cruises on the Danube, the Elbe, the Main, the Rhine or whatnot. I wouldn’t just buy tickets; I’d buy the cruise line.  They’d be pretty impressed.

I shouldn’t be sarcastic like that, but I’m deeply skeptical.
