Unleashing the Potential of Gravitational Generator: A Theoretical Approach

AI Thread Summary
The discussion explores a theoretical concept for a gravitational generator involving drilling a hole through the Earth, wrapping it in a superconducting coil, and using a magnet to generate energy. It is suggested that the magnet will slow down as it moves through the coil, supported by examples of magnets dropped in copper tubes. However, the idea is critiqued for being a one-time energy source, as the magnet's oscillation will diminish over time, leading to a net energy loss. The energy required to create the hole and the infrastructure outweighs the energy harvested from the falling magnet. Overall, while the concept is intriguing, it presents significant practical challenges and inefficiencies.

Ok this one is purely theoretical and I'm going to just make some assumptions.
1. No Debris will block the way.
2. Its A vacuum
3.The structure won't collapse.

Ok, first we drill a hole through one side the Earth and out the other. We then wrap the new whole in a superconducting coil of wire. At both ends of the wire attach a battery to collect the energy. Then drop the magnet.

Would the magnet be slowed?
I came up with this today and only researched a little on how magnetic generators generally work.
Squares are magnets. The brown lines are the wires previously mentioned.

Yes, the magnet will be slowed. There are videos of people dropping magnets down copper tubes on youtube that should show this.

Thanks for the reply I had this idea milling around in my mind all day. :D
 
This is only a one shot device, remember. The magnet will oscillate along the polar axis but the displacement will gradually die down as energy is used up. It is a very expensive way to harvest the PE of a falling object. Remember, you had to dig out all that material to make the hole in the first place. That would involve much more energy than you will get out.

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
