how can I reflect light over long distances without losing so much of its power? Air particle niggers keeps stealing my photons before they can reach the target, so much of the power is lost >:*(

I guess you can construct a vacuum tube from A to B to get all the light across without loss, but how can I do this over long distances like 2 kilometers?

fiber optic cables?

isn't that only for transferring data?
I want to transfer energy :(

what does this even mean? do you want to reflect a light beam sent to you? or are you just dumb and can't use proper words like send, transmit?

>Air particle niggers keeps stealing my photons before they can reach the target, so much of the power is lost >:*(
go back to /pol/ also it's not just particles that cause a loss of power but that light spreads out as a square of the distance.

>I guess you can construct a vacuum tube from A to B to get all the light across without loss, but how can I do this over long distances like 2 kilometers?
one must assume that one is talking about a long tube with no air in it, but one would also assume one was talking about old timey vacuum tubes. one needs to be more clear.

oh if only there was some way one could explain in more detail about what one wants instead of talking in 4chanian.

>>2049396
they use a collimating lens concave focusing mirror or a fresnel lens to get a more narrow beam. moron.

either way the beam will still spread out as a square of the distance penis breath.

OP please tell us exactly what you are trying to do. Are you trying to reflect the sun onto something for energy conversion? or are you trying to take energy you are producing another way, convert it to light, and send it somewhere remote and convert it back? If the first you just have to focus it best you can and deal with scattering. If the second, there are better ways, like microwaves (but beware cooking anything that gets in the path).

For lighting or what? There are (or were) commercial solutions to gather sunlight and pipe it inside a building via fiber optics for lighting purposes

>> No.2049742

use solar panels, wires, and LED light bulbs to illuminate with sunlight the fantasy bunker that you'll never build nor have the capability to ever build.

there is only one bunkersan and you aren't him.
