I am always skeptical about these machines. The fact that the flywheel wobbles concerns me about this machine.
If they are profit driven (which is sounds like they are) we may never see this. It would be an "investment" for the oil / coal / solar / wind / hydro-electric companies to buy the invention and burn it.
If they want to change the world they have to start making these things and selling them for a "reasonable" price or publish plans and give their "rights" to profit away. There are way too many people that have too much money to lose.
Think for a second how many people are involved to give you energy in your home.
Coal - Miner, guy who builds the machinery, accountants / office staff, train engineers, train car builders, (all of the people that bring petroleum to market - they fuel the trains), power plant workers / engineers, regulators, pilots that inspect lines, guys who lay lines, meter man, cable manufactures, politicians lose an energy lobby, everywhere these people shop - and I am leaving out A LOT OF PEOPLE.
And I can displace all of these people for:
5000 Australian dollars = 4314 U.S. dollars
That is a few years of power bills. Sign me up!
