Your idea is similar to this spinning disc toy. I recently made this toy for my grand-daughter using a plastic yogurt lid and a length of string.



You gently pull on the string and the disc spins until it stops spinning. After the disc stops spinning, you gently pull on the string and the disc starts to spin in the reverse direction. It seemingly will go on forever. Obviously, it does not. There is loss of energy owing to friction (air friction on the disc, the major load, and lost of energy in the twisting of the string). This energy lost must be replaced by pulling on the string in order for it to spin indefinitely.

In your proposal, energy will be lost in the heat generated by the lamp (the major load) and the resistance in the connecting wires.
In other words, you cannot get more energy out of the system over and above the initial energy. To do so is called over-unity which violates the 1st Law of Thermodynamics.

 

The concept of variable capacitors can be applied to regenerative braking in electric cars.

When you need to stop the moving car, a variable capacitor is applied across the electric motor (now serving as an electricity generator). The generator charges the capacitor. By increasing the capacitance, the capacitor can "suck" up more charge while staying at a low voltage.

The charge on the capacitor can be "pushed" out to get the car moving again or to charge the batteries by reducing the capacitance. This is not over-unity because energy is consumed while reducing the capacitance, besides the obvious fact that energy is also consumed by moving the car.

This concept is impractical because creating a variable capacitor of significant capacity is beyond the scope of today's technology.

 

I always liked Robert A Heinlein's definition:
1. You can't win.
2. You can't break even.
3. You can't quit.

Just a point: that’s actually called ”Ginsberg‘s Law”, and it is attributed to Allen Ginsberg but it is also attributed to several others, in various forms—but none of the people who take partial credit are Heinlein.

In full, Ginsberg’s version is:

0. There is a game.
1. You can't win.
2. You can't break even.
3. You can't even get out of the game.

 

Hi,

What I like to point out from time to time is that we do not know everything yet, all we have is our current sum of experience that we try to use to predict the future. I wonder if 200 years ago anyone would have believed that a quantum computer would be possible.
We don't know what we can do until we get there

I would like to point out that we know a lot, to a very high degree of precision when it comes to basic things like CoE and CoM. Nothing we learn is going the change thermodynamics as we now understand it, with the measurements we currently have or can conceive from any present valid/provable scientific theory. Any new theory we discover MUST ALSO be in agreement with current experiment, to at least the precision we currently have. So no, we will never have self-levitating (free energy for nowhere) oranges ,apples or rockets.

Action without energy is called Magic and Magic is in the realm of the supernatural outside of science.

You can add a colored paper with a marker to the disc, You will get Newton's disc..

 

Long time ago my father made me one of those using a disk of wood, which had a little more rotational inertia so it worked pretty good.

 

If magic can be proven to exist it then becomes the realm of science. Science is nothing but observable facts and predictions derived from those facts come,physics has a pretty good track record so far. As much as I love fantasy we live in reality and it has rules which we are trying to derive with some success. I'm kind of curious if the Casimir effect (AKA quantum foam) can ever be used for anything useful other than knowing it exists.

It's real but it's more a limitation than anything useful today but people are working on uses.

Overcoming the Casimir Force, a Fundamental Limitation in Quantum Tech

“[Imagine] two parallel boats out at sea and they’re close together. There are ocean waves in the space between the boats and there are waves outside. When these boats get too close, they become attracted to each other, and they will collide [because there are] more waves outside than there are between them,” he said.

In other words, the waves between the boats are incapable of equaling the force exerted on the boats by the waves pushing from the outside. This outside force becomes stronger as the boats near each other, with the waves in the middle having less and less space to exert a counterforce. In the end, the outer waves force the boats to crash.

 

Hello again,

I can imagine that the whole earth was used as a dielectric for a huge, huge, huge capacitor with plates 8 thousand miles square on two sides. Imagine how much energy it would take to move even part of the earth out from between the two plates, then imagine how much energy it would take to move a significant part of the earth out from between the two plates, then put it back.

It's interesting that energy is such a fundamental entity that has to be dealt with in various ways. There does not seem to be a way to trick energy into coming into being without it disappearing right away. It seems we can only move energy from one form to another.
To show that nobody has even theorized any way around this yet is the 'invention' of the Dyson Sphere. I don't think this would be even a hypothetical concept if there was any way around the 'creation' of energy thing. Energy may be the only thing that is actually real.

Apparently, we can only 'gather' and store energy similar to how we gather and store food

 

We all live in an extremely limited reality, with just 5 rather mediocre "Senses".

Most of the people of this Earth act just like "Crabs-in-a-Bucket".

This is the exact mechanism that promotes Censorship, and impedes beneficial improvement for all people.

When the time is appropriate, someone will stumble on to
"the next big advance" in our understanding of our "supposed" "reality".

Think about it for a minute ............
Promoting any kind of Censorship makes YOU one of those Crabs at the bottom of the Bucket.
