Anisa, I thought I'd chime in on this. I've got a Ph.D. in electrical engineering with emphasis on power systems. My life is devoted to the study of generation, transmission, and distribution of electricity and everything related to it. Plenty of forum members can personally vouch for this since I speak at TMC Connect and have numerous publications with hundreds of citations. I am going to disprove this technology using power system economics, since it's far easier for people to grasp.
First there are laws in this country. Laws that say if you have a generator, and can produce electricity, the utility has to buy from you. There are also deregulated markets where anyone can build a generator, and sell electricity into the market. If this technology actually worked, someone would build the generator and start making infinite, free electricity. They'd be able to sell it, and get rich. They'd build more generators with the money, and make more money in the process. They could make so much that they'd displace every other generation source in the world. The question is, are they?
You'll try to argue that some cartel conspiracy is fighting the tech, because they've sunk their money into outdated technology, but this is also flawed, because the patent has expired. If I own tons of oil fields, and I can make a fortune on newly discovered free energy, which is cheaper than my oil, I'll just cut my losses and make a bigger fortune on the free energy. The oil is still very useful for synthetics and chemicals.
If no one is making a fortune off of a freely available technology that promises to allow you to make a fortune in electricity if it works, then it doesn't work and you're arguing that the capitalists aren't really that greedy.
