This video popped in my suggested list today https://www.youtube.com/watch?v=RiYOw5NsoKY relevant parts are beginning and 2:51.
While I don't get the point of transmitting light from the sun to the house via optical fibers rather than just using the windows because the sun is out or turning it into heat, then electricity and using that, it still got me curious.
Are there materials that are flexible enough to be used as cables but will be able to transmit enough light equivalent of say one 60W lightbulb without overheating and melting?
Again, I don't see much point in this, but would be a cool thing to have in the house even to just impress the guests. Like a "light bulb" emitting light just because its a sunny weather.
