Mike Fedderson asked me a question about how to light a tunnel with natural sunlight at the Wonders of the Day thread. To prevent things from getting too crowded there I have made a new thread for this topic specifically.

He mentioned the coke bottle sunlight method which is cheap and easy to do as demonstrated in the video below:

So, the main idea is how to get sunlight in buildings and tunnels. Some possible ways of this doing this could include:
-solar light tube (basically a cylindrical shiny piece of metal with glass ontop)

-Fiber optics could be used in similar manner. Essentially, from my understanding, a fiber optic cable is is just a long tube that has light come in one end, and it bounces around inside until it exits the other end, kinda like a solar light tube. According to an article by Building Green, this method of fiber optics for lighting deep down is more expensive than the tubular skylight method which may be a hinderance.

here is a look at how fiber optics work:

What do you all think are good ways to light a building naturally, or as Mike was wondering, a tunnel?
