Is it a lump of coal or a man made weight? Perhaps a rock,that has solar energy in it......

Hopefully we will find out at high noon on May the 7th,when we smash the ceiling.

Enough energy to deflect the harmful proton rays of the Sun from the Earth's surface,or is that something else.
As I said above, it doesn't create the potential energy. If there's a weight on the floor, how does that weight get potential energy?

By changing it's frame of reference?
By doing work.

E=-G mM
. R
Should read mM over R
Or to put it another way:
In classical mechanics, two or more masses always have a gravitational potential. Conservation of energy requires that this gravitational field energy is always negative.[2] The gravitational potential energy is the potential energy an object has because it is within a gravitational field.

what the chap has invented is a delightfully eloborate, and no doubt extremely efficient, toy. where does the energy come from? magnetism, and a lot of carefully balanced components that dont consume much energy.
what it wont do, as with so many claims at perpetual motion, is either scale or do any useful work. as soon as you apply some sort of mechanism to capture the energy of the moving ball, energy will be extracted, the ball will slow and the toy will stop.
re gravity and energy potential, its a one way potential, once used you have to input energy to reset the engery potential.

oh, wiki. soz, i dont know how to do a link.
searching the first law of thermodynamics may help!

Well it's all relative, what if the weight doesn't move but the frame of reference is the centre of the planet and not the floor?
The floor is just where the weight is, it still won't move or do anything.

wiki states, energy cannot be created or destroyed
and;perpetual motion machines are impossible
"The first law of thermodynamics is a version of the law of conservation of energy, adapted for thermodynamic systems. The law of conservation of energy states that the total energy of an isolated system is constant; energy can be transformed from one form to another, but cannot be created or destroyed. The first law is often formulated by stating that the change in the internal energy of a closed system is equal to the amount of heat supplied to the system, minus the amount of work done by the system on its surroundings. Equivalently, perpetual motion machines of the first kind are impossible."
That ball creates sound and heat, and it's claimed that it's perpetual motion. Looks like the rule has been broken to me.

The enviroment of the universe enables gravity and the universe came from energy, just like the spin of the earth enables a magnitism process.
If you are saying this is a hoax then it may or not be, but at this point we are discussing gravity.

Yeah, but does the PE change depending on the frame of reference?
