Perhaps his cloaking device failed?
Everyone.

Instead of Monday, may be as late as next Friday...

Sounds about right ;)

High school thermodynamics should tell you that this is impossible. A perpetual motion machine of the second order, if you got this running without energy input... but they seem to be claiming that you actually get energy out of it. That's a perpetual motion machine of the first class.
I like the following words of Sir Arthur Stanley Eddington (in The Nature of the Physical World. Macmillan, New York, 1948, p. 74. ) that have bearing on the proposals of perpetual motion machines of the second order:[quote]The law that entropy always increases -- the second law of thermodynamics -- holds I think, the supreme position among the laws of Nature. If someone points out to you that your pet theory of the universe is in disagreement with Maxwell's equations - then so much worse for Maxwell equations. If it is found to be contradicted by observation - well these experimentalists do bungle things sometimes. But if your theory is found to be against the second law of Thermodynamics, I can give you no hope; there is nothing for it but to collapse in deepest humiliation.[/quote]
(You'll have to excuse me for focusing so much on thermodynamics, but I'm teaching a class and we just finished the topic, I gave that quote to my students, so I had it available)
Too much stuff there to go through it all, and too much advertisements and enticements to "buy the book, buy the DVD" to take it as anything other than a money making scheme.
Sure, you can make money out of solar energy and hydrogen... just write a gobledygook-pseudoscientific book about it and fool people into buying it! :D
Seriously, some of the solar energy ideas there look sound, but the hydrogen energy bunk throws my baloney detector off the scale and makes me doubt the veracity of the rest.
I could actually check if the reaction proposed there for Aluminium, salt water and air membrane is even feasible, but I don't give enough credence to the claims there to care to do it.
And then there's the little bit of information that gets lost in many discussions about hydrogen as a clean "fuel." There are no hydrogen mines nor wells. To use hydrogen as a fuel you have to produce it and to produce it you have to spend energy, and there's no way you can get more energy out than you put in. Hydrogen is more of an analogue to electricity than to a fuel.
Even if the claims in that page that you can get hydrogen from simply reacting metals and water with some base or acid present were completely factual (which I doubt) once you looked at the whole picture it's very unlikely you'll get more energy than what had to be spent in mining and refining those metals.

hmmm...so the bag of charcoal I have at home isn't just a fuel to cook some tasty bar-b-que, its an investment!

[QUOTE][b]Hydrogen is more of an analogue to electricity than to a fuel.[/B][/QUOTE]I think hydrogen is closer to fuel because it stores that energy.
(electricity is more like way for immediate transfer of energy)

I am willing to overlook silly shape and missing street-worthyness.
That is some seriously *mean* efficiency. :eek:
