Is it possible to have perpertual energy, like having a solor powered light that runs on light?

Question

Just get the light going with another light source then shine it at the panel then hey perment light? perpetual energy?

Answer 1

Energy can not be created or destroyed (only changed into another form) so energy could be described as 'perpetual'.

However, you are probably talking about perpetual motion, which is a non-starter.

Answer 2

There will come a time when the equipment breaks down or there is insufficient solar energy in the cells to power it overnight. It is assumed that during spells of low light, the stored energy gradually gets less each day and at a point, you will have no light.
As a response to the above, the magnets need an electrical circuit running on some power source to provide direction. As in the Jap Trains, a lot of electricity is used to change the polarity of the magnets to cause foreward acceleration.

Answer 3

What's powering the light that's shining on the solar cell? Using a solar cell on each light and pointing them at each other wouldn't work because there will be a net energy loss while lighting the bulb (heat and resistance in the wires) and getting all the light to actually land on the other solar cell.

The first two laws of thermodynamics:
1. You can't win.
2. You can't break even.

These are not man-made laws. These are laws of nature and have NO EXCEPTIONS. You can't repeal the laws of nature. You can only obey and apply them.

Answer 4

Yes, but how do you get the other light? And if the conversion efficiency is not 100% (it is not possible theoretically), you spend more energy to produce less energy.

With sunlight also, the energy is coming from a nuclear fusion reaction and is converted into electricity through the solar panel. A small fraction of the total energy only and the rest?

Answer 5

Sadly, it doesn't work quite like that. The problem is that Solar panels are very inefficient at turning light into power and to make things worse, light bulbs are very inefficient at turning power into light! If you could create technologys that operated at 100% efficiency you would be closer to what you suggest. However, just to add another angle... Even if you could get something to run at 100% efficiency, the light would still shine onto and reflect off other surfaces and not just your solar panel. Therefore your panel would not be absorbing 100% of the light produced. So. infact you would need your system to run at well over 100% to conpensate! And that's impossible to do!

Answer 6

Nope, this would not happen. The efficiency of energy conversion is not 100% (you cant make it 100%). Heat energy will be lost as the electrical energy passes through the nichrome wire of the bulb. Furthermore, not all light energy emitted will be collected, as some of the light energy may penetrate through the system (which makes the edges of the torchlight glow when you switch it on).

Answer 7

I have often thought of finding a way to produce perpetual energy, I wondered if a generator could be made by using magnets to turn it, my theory is that opposing poles which push away from each other could be mounted in such a way that they will keep turning and this movement would then turn the generator, the Japanese use a similar method to run their trains, to me it sounds feasible but what do I know, there is probably a reason that this has not been used yet.

Answer 8

purely like a sturdy liberal, I dutifully went out and offered lots of the compact-flourescent bulbs while they became accessible--and likewise few extra by means of the years, just to furnish the technologies each and every achievable probability to instruct itself. yet I ought to confess that this could be a sort of aspects the place the wonderful-wingers are surely impressive, and the libs have been shown to be unscrupulous con-adult males (and girls). The bulbs purely do no longer furnish the candlepower that they declare to. and that i do no longer choose fancy measuring kit to detect the fraud, because of the fact this is not a diffused factor. this is obtrusive. Even the brightest ones are no longer sturdy sufficient to confirm with. additionally, the "easy temperature" isn't as this is rated. the sunshine is lots chillier and greener than this is touted as being. additionally, the existence-span of the bulbs isn't what this is meant to be. no longer a single between the bulbs that I surely have used has further everywhere close to the hours that have been promised. And consequently, the performance and coffee value expenses are no longer everywhere close to what they are cracked as much as be. And besides the incontrovertible fact that the wonderful-wing mutters and complains approximately it, no person has yet taken legal action against the legislators and engineers who've fraudulently marketied those issues and who're plotting to make incandescent bulbs unlawful or prohibitively expensve. And legal action ought to be taken against those crooks.

Answer 9

I was thinking of the same problem earlier on.

I thought about centrifugal forces at work. Orbiting masses rely on gravitational forces to keep things in orbit, yet the energy is technically constant and self sustaining. My theory is that perpetual energry can be generated through centrifugal forces.

Answer 10

perpertual energy is not possible. so no sorry. and if it was the worlds goverments would hide the answer from us and use it for mass profit or war and you know it, its a bit like the cure for a common cold , they would never release it due to the masses of cash the medical industry make.
