"In this house we obey the laws of thermodynamics!"
There have been many sightings of a so-called over-unity phenomenon. These may vary greatly, according to the contemporary world of physics.
But one thing all scientists, and even Homer Simpson agrees upon is the law of Thermodynamics.
This one states that the amount of energy/matter that exists within a system cannot be greater or lesser than what we put in earlier.
But somehow it seems there were some 'experiments' that fell through the cracks.
Like the supposed car running on water. Well, I've never heard of such a ridicolous thing. Or have I?
In fact I had heard of such a thing. Here's how it breaks down: water (H2O) doesn't burn, unless it gets broken down into its parts first.
This is simple science. There are already running, fabricated cars running on burnable hydrogen(gas). This approach hasn't really taken off, because as you know, you have to first use energy to get hydrogen. Whatever chemical, biological or nuclear reaction you use, you first have to put a lot of energy in, to get usable hydrogen(gas).
There is also another burnable gas you can get from water, Oxyhydrogen. Now, this is the good stuff. This is a metastable gas, meaning because it is by definition electrically charged, and it will fall apart, and form water again, if the charges are gone. If you leave it near a magnetic object like some metal placings: gone! If you burn it: gone! Or better, turned back into water.
