Physics, Astronomy & Cosmology / Charged or discharged

« on: 02/09/2016 09:43:50 »

Dear all,

I have an amusing experiment with my smart phone charger. That is, after charging it fully, I connect its input and output toghether, and get surprise result.
Could you see in my youtube clip and give your explanation here

Thanks

Physics, Astronomy & Cosmology / Can solar energy be converted to mechanical energy in this way?

« on: 29/07/2016 09:40:02 »

I have an experiment to transfer solar energy to mechanical energy.
First of all is a cone inspired by an axis.
On the cone are two tiny cups of water.
The whole system is put close to the glass in the room to get sunlight and avoid affection of wind
Then, there will be interaction between sunlight and water molecules, which makes the cone rotate
It is better to implement this idea in tropical countries, where there is plenty of sunlight and temperature is so high, which can heat the water cups
See my clip for more detail

Science Experiments / Can a bulb be used as convex lens?

« on: 15/06/2016 13:12:07 »

Dear all
I have used a bulb which is filled in with water, it works like a convex lens to concentrate solar energy.
The performance of the water bulb gets highest level when I incline the bulb like in the clip. Solar light beam focus on a bigger dot, in compared with the dot when let the bulb standing vertically.

Physics, Astronomy & Cosmology / Re: Energy conservation violation

Hi all,

Unfortunately no. The limit of my experiment is that I made conclusion based on observation. This experiment is done by me, an amateur experimentalist, at home; not in a well equipped laboratory.

However, I simply make a assertion that I just use a small force to move the cylinders to go a short arc, while they rotate many rounds after that.

If I can improve my model to rotate longer, for example 10 minutes, you can see the different

Thanks for your feedback

As RD suggested, you have to take into account the electromagnetic energy. Did you do that?

Sorry no :-)

I just take into account the mechanic energy.

However, I think this model can be used as a rotor of generator. We only need to use small manual force at the beginning, and the system will generate electric current, without fuel. Provided that This model must be improved to rotate longer

Am I right?

Physics, Astronomy & Cosmology / Energy conservation violation

First of all, I would like to say that this model is NOT a perpetual motion. It will stop eventually. What I want to say here is that the output useful work seems to be greater than input energy

My system consists of 2 elements. Each element is a cylinder put on an axle. There are two permanent magnets stuck on each cylinder, with their north poles are faced outside. In the youtube clip that I will show you below, you can see the magnets of the first element are painted in blue, while those of the second one are crossed with X.

I turn the cylinders slightly so that the north poles of the magnets are faced each other. Then, the thrust between magnets make the cylinders rotate.

A single cylinder on an axle itself is not the system. It is an element of the system, which consists of 2 at all. Therefore, the thrust between magnets is not external force which affect system. It is comprehended as internal force between 2 elements of the system. The thrust from the first cylinder makes the second rotate, and the thrust from the second, in its turn, make the first rotate. Each component act as the cause to make the other rotate, and it acquires the affect from the other to rotate.

While the input work of the system originates from a small force making cylinders moving short arc, and make magnets facing each other, the output dynamic energy is much higher. You can see in the clip that both cylinders rotate many circles, which create output useful work much greater than the work to make the magnets facing each other.

Here is the link of my clip

Your comments are welcomed to determine that if energy conservation is violated in this case or not

Physics, Astronomy & Cosmology / Re: Non-stop engine

« on: 19/12/2012 04:13:17 »

Hi CliffordK,

I have put the whole model in an isolated room, with door and windows closed. And I also make the second as your suggestion. It got the same result.

My concern is that the amplitude of the tail swinging is so small that it's hard for me to convince people. And until now I don't know how to increase

Physics, Astronomy & Cosmology / Is this a perpetual motion machine?

« on: 18/12/2012 03:34:29 »

Dears,

I am investigating a way to make an engine that can run continuously. Currently, my result is so positive.

1. Tools and facilities:
- The main component of this model is a wooden toy with dragonfly shape. Its head is a rectangle which is curved upward, with long tail
- A sharp pillar
- A medium sizes magnet (In attached screenshot it is the round and black piece)
- A tiny magnet

2. Model
- Stick the tiny magnet under the tail of dragonfly shaped specimen. The gravity of magnet makes this specimen settles down toward the tail.
- Then, touch the sharp peak of the rectangle head of the specimen very slightly into the top of the pillar. It makes the balance status of this dragonfly toy is very unstable. It is very easy to drop down as seen in attached screenshot
- Put the medium sized magnet at the base of the pillar so that its upward pole is the same as the downward pole of the tiny one (i.e. south to south, or north to north), and they are face to face as shown in attached screenshot
- Keep the whole system in an insolated room, with all doors and windows are closed to prevent air wing influence.

3. Operation:
- The attraction force between 2 magnets makes the tail of the specimen is pulled down slightly, before it is up again. Then a new period starts with the up and down movement of the specimen tail, again and again etc.
- The position of the medium sized magnet is adjustable so that it can give best result to the movement of the specimen. If the distance between magnets is so far, the force intensity is so weak to result in movement. Otherwise, the strong attraction force from the medium sized will also prevent the specimen from moving.

I let my model there overnight to make sure that there is no stopping. And luckily it does not stop until now.

I post my article here so that any interesting individual can follow and replicate my experiments.

All of my expectation that you can contact me and replicate my experiment
