It's a nice idea, but I'd like to see what happens with them on a cloudy day.
I suppose they turn the electric lights on then.
That is actually a very nice way of saving energy. I wonder if this kind of technology could be used in buildings that have more than just a thin sheet of metal for a roof. Natural light in a room with no windows is just cool!
mmmmm.....steak *drools*
But seriously, in a place where it never rains, no problems with leakage with those things I guess. And considering it's always 90000000 degrees, the sun is out every day. What happens when you get up to take a shit in the middle of the night though? O.o
nice
The Russians used a pencil.
This reminds me of the millions of dollars NASA spent trying to perfect a pressurized pen that would write in zero gravity on space missions.

I would also like to add I actually used a couple of those pens in the Navy. They hardly work for shit. Maybe you have to be in zero g for them to work. Bring on the pencil.
engineering something with more complexity for no reason is bad engineering. cutting a hole in the roof with and installing a hatch/laying a board over it would provide much more light and better protection from weather.
It's a transparent interface on the ceiling that doubles as a transparent interface on the roof.
Revolutionary.
You can actually see the sky. And it provides light when there's light to be had from the sky.

False. Both the americans and the soviets initially used pencils, but it is dangerous if a piece of graphite broke and floated around inadvertently. It could affect instruments, get into your eyes, etc. Also, a free oxygen environment makes the wood of the pencil and probably also the graphite more prone to burn or combust.
Good analogy on seeking simple solutions to a problem, but completely made up and incorrect.
