That giant wheel thing needs to be running indoors and out of the wind and sun, before it can be actually tested.
That off-balanced wheel design has been around since the wheel was invented,
but it's 'perpetual motion' can't keep it going for very long.
If it could, every body would have a small working model on their desk..
In the video, the old man was pulling on the wheel (by hand) as it moved by him..
The Rube Goldberg Ball-on-a-Rail thing looked cool. I think the hidden heavy pendulum
inside the center column might be where a hidden battery is stashed.
If not, it might be somehow using the earth's rotational energy. Check out the Foucault Pendulum.
