Self generating lights

I dont know anything about this subject but why don't we have lights that absorb energy off there own light source. So like a light with a solar panel type device attached to it making it be able to stay on forever for free

i think solar panels absorb only real uv rays and solar energy and shit :/

yea, they dont absorb enough for a continuous flow to be possible, or arent efficient enough yet with the light they absorb. and for them to be one 24/7, there would have to be some batteries with stockpiled energy or some crazy efficient lunar panels for nighttime

According to the law of conservation of mass you would have to recapture all of the light to make it self
sufficient so it wouldn't povide us with any light ;) but maybe a small solar panel at the base? But I'm sure that the technology to repurpose the light energy back into the bulb wouldn't be cost effective

psssssh well the technology we have these days will figure away to do that to all you other commenters

theoretically, if you were to get a hallogen light (like what you would use to grow your weed) with a solar panel on it, and you rigged mirrors in all the right places, you could project the light back onto itself. if the weed in your closet beleives its real sunlight, whos to say the solar panel wouldnt?

Like a perpetual light machine? Well, 2 things:
1. Real world conditions. Solar Panels are inefficient. The average efficiency of a solar panel is about 12%. That means only about 12% of the light that hits a panel will be converted to electricity. Lights are not 100% efficient. A significant amount of the electricity that goes into a light is wasted as heat or other forms of energy, depending on the type of light. Thus a solar panel would convert ~12% of the light emitted from the light bulb, which is only a fraction of the electricity that went it. This system would quickly run out of energy without an outside source.
2. Conservation of energy. Let's assume you have a 100% efficient light and solar panel assembly. The only way you can keep the light lit is by capturing 100% of the light that came from it. Thus, you get no light to use.

Good luck, and good smoking

think were all missing the obvious conservation of energy idea
the whole idea behind it is that there is always the same amount of energy in the universe and it can only move not deteriorate or propagate in any way so in theory his idea would work but when a lightbulb is turned on some of the energy goes to light production but alot of it also goes to things like heat and even momentous energy because of the kinetic energy difference between the two wires on most halogen bulbs
so the bulb might be producing 50% light 50% heat energy and absorbing both to turn it back into light energy requires energy itself to be sacrificed because a 100% efficiency does not exist

im to high to be rambling so just try and make sense of it

I believe Nikola Tesla was able to do this as well as crazier things. look him up

Tesla was the greatest engineer ever. The world would be a much different place if people just listened to him.

I think that you would lose a ton of energy. Meaning it would be more expensive to run the lights than you would get out of whats absorbed. It would just be wasting even more energy. Unless we can get it where you can absorb more energy than it puts out, which would be hard.

Read an article in the new york times science section a few years back. Scientists had discovered a micro-organism that produced a small amount of electrical current when it reacted to sugars. They were trying to find ways of keeping them alive in small storage the size of pills so that they could be travel sized. The scenario that was given in the article said something like "if you got lost hiking and your cell phone battery died you could hook your little critters up to your cell phone and use them for a short amount of time. All you'd have to do is drop some sugar in the container and they'd naturally start producing charge."

I figure if they could combine these little critters with some bio-luminescent micro organisms you just might get your wish.
