Actually, we CAN tell you that it won't work. As has been said by several previous posters, you can't get more out of a closed system than you put in.It is not impossible. You guys make is sound like we can't come up with technology to make it work. I understand physics and the laws of Thermodynamics but you can't tell me that it won't work. Regardless of the laws of physics. According the laws of physics, a bumblebee should not be able to fly but they do.
With rotation of the axel [sic], you could generate enough power to recharge the system and to provide power to internal systems. However, you cannot use a standard alternator that is currently in use by automobiles. This is an idea that is being discussed at great length by engineering students in the University I attend.
I once considered the exciting concept of an electric motor driving a generator, which created the electric power to run the motor. Excess energy could be taken from the generator to run other devices! After thinking deeply about it for several minutes, I intuitively realized it wouldn't work. Not bad for someone who was six years old at the time.
Forty-some years later, with a degree in physics and having almost 30 years experience in electronic design does tend to give one a certain understanding of how things work, what WILL work, what WON'T work, and WHY.
You may discuss these things in University, but surely you must discuss their severe failings immediately after.
Not only does your statement, "It is not impossible. . . I understand physics and the laws of Thermodynamics but you can't tell me that it won't work" show an inappropriate level of understanding, but your attitude invites attacks.
