"FREE ENERGY"? Like free lunches, there ain't no such thing as FREE ENERGY.

What Tesla demonstrated was the ability to radiate energy that could be utilized to produce work. There was a cost to generating and radiating this "free" energy. There are two significant problems with this technology.

First, while transmission is significantly cheaper, no copper wires, anyone could use the radiated energy without paying for it. Of course, as long as the guy who generated and radiated the energy didn't run out of money it was "free" to users. One answer is to tax everyone and let the government do the generating and radiating.

Second, electromagnetic radiations may or may not be unhealthy. This topic is best discussed by nutty conspiracy true believers. Personally. I enjoy basking in the radiation of my WIFI, mobile phone and Bluetooth stuff. Just as long as the aluminum foil is tightly affixed to my head I fear not radiation from CIA, NSA or DIA sources.

FREE ENERGY is nonsense. Other than the warmth of the sun and gravity, energy is not free. Once you begin to alter any energy you begin to incur costs. Just because you let others pay for it and it is at no cost to you does not make it free.

Obama proposed "free" community college education. Free to the student but paid for by taxpayers. In fact, in his "free" education he would tax use, for education, of education savings accounts funded by after tax income of the savers.

Generosity is something done with your money not the money you take (tax) from other people.

As to "CORPORATE GREED," well I am sorry if I am dismissive of this term. Someone once identified "Seven Deadly Sins" and "Greed" is one of them. Note "Envy" is another. GREED is invoked as a ideological pejorative to stigmatize hard work, intelligence, luck and success which result in the accumulation of wealth. Those that whine about GREEDY whoavers, usually will also portray themselves as victims of some sort of organized conspiracy. Not wanting to digress into ideological bullshit, let me say one man's efforts and successes are another man's envy which is carelessly labeled GREED.

I am sorry to learn the terms "IPO" and "PUBLICLY HELD" are considered identical, colloquially or otherwise. Private companies transition from being "private," or closely held, to being "public," with shares offered to anyone who wants buy and those shares are then traded freely in markets. This transition is (I am using US terminology and law) highly regulated, extremely expensive and dominated by lawyers and accountants. This transition is a one off EVENT, actually a process, never to be repeated.

My students in Beijing would often play what they colloquially referred to as "NBA." But, you will have to trust me on this, shooting hoops and playing pickup games on school basketball courts is not the "NBA."

Dazzer, I understand the difference between PV and solar-thermal power generation. I also agree that PV is exceeding harmful to the environment. US manufacturers of PV panels have gone out of business, in spite billions of tax payer dollars partially because of the all in production costs including pollution abatement. Chinese manufacturers are not similarly burdened.

In fact, many products with high pollution factors or are just plain hazardous are now imported to the US from China. Compliance with US pollution and safety regulations is so costly, it is much cheaper to export the jobs. The pollution and hazards are also exported. The Chinese just snap up the business.
