Saw it advertised on tv. Never needs batteries. Seems very suspicious to me. More free energy.
You just don't get it do you?!?!?!?!
THIS IS NOT FREE ENERGY!
Just because the light doesn't use the chemical energy stored in batteries, it does not necessarily mean that the energy comes from nowhere. You are
expending energy from your hand and arm by shaking a magnet through a coil. This causes the magnet to pass through a coil of wires. This creates a
changing magnetic flux. A changinc magnetic flux through a coil of wires causes the electrons to flow in that coil, causing a current. This current
then powers the light.
IT'S NOT FREE ENERGY!
The light will stay as long as the magnet is passing through the coil to make a flux. The magnet keeps passing through the coil as long as you shake
the flashlight. Your arm will get tired BECAUSE IT IS CONSUMING ENERGY. You arm will need more energy. It will need fuel.
It will use glucose. It gets the energy from glucose by breaking it down unto two molecules of pyruvate, mixing it with oxaloacetate to make citrate.
This is then passed around and broken down bit by bit and reformed into a new molecule of oxaloacetate, which is then mixed with a new molecule of
pyruvate that came from a new glucose molecule. The bits that got broken off are used to form a molecule called NADH. The electrons from this are
passed through an electron transport chain in your mitochondria to help phosphorylyze adenosine triphosphate, the freakin' molecule that is VERY HIGH
IN ENERGY, AND IS BROKEN DOWN TO RELEASE ENERGY IN YOUR BODY WHEN IT NEEDS IT.
So, in the end, you can honestly and scientifically say that your precious perpetual flashlight is actually powered by TABLE SUGAR.

E = MC squared doesnt answer the question of what energy is made of. It doesnt explain where atoms come from. It doesnt explain what matter is. It
doesnt explain anything but a "formula" of how it appears to work and how it appears to behave.
Perpetual might not be the best word. Even if you create a machine that can operate forever, what if it breaks? What if friction starts to wear it
down and it falls apart? What I mean when I say perpetual motion is something in theory could work forever not considering if it stayed put together.
I was saying about the computers and radios because you said that people since the 13th century have been trying and failed to create a perpetual
machine. And you make a statement that it must not be possible because of that reason. I was just saying I didnt agree with you because someone in the
10th century would look at moderan day technology and might think it impossible. Just pointing out your faulty logic.
Friction will not only wear out your machine, but friction actually generates heat, which means that energy is escaping from your machine, which means
that will NOT last forever, or even a very long time for that matter.
Here is what physicists will admit: There are certain things that we cannot explain WHY they work, but we absolutely can explain HOW they work.
You can't have perpetual motion because parts of your machine must touch each other, and therefore must have friction. Electricity is very fickle -
it is not magical and does not travel only in the direction of your wire. The electricity actually tries to radiate perpendicularly to the direction
of your wire. You LOSE energy in wires. It cannot be stopped.
And if some jerk in Europe or wherever invented a machine that puts out more energy than it requires, then why doesn't he rule the world? Why
doesn't he end world hunger? If his machine actually creates a positive output of energy, then he would have an infinite fuel source. With an
infinite fuel source, it could be converted to a fuel source that plants and lifestock could use. With an infinite source, there would be infinite
animals. The mass of all the living things on the earth would increase because there is an infinite fuel source to power them all.
Gimme a freakin' break.
