Piping sunlight

I was searching around and came across this idea for grow rooms.

dude... are you kidding me, how come I just realize this is a possibility.. im too lazy to read the link.. but imthinking.... angle tubez sticking out of your house with crazy angled mirors while the devises turn with the sun

I thought you were talking about using mirrors n shit like the pharohs used to light up their pyramids internals.

That stuff wouldn't work for shit. It would cost like a thousand bucks a for 100 watts.
