It's not an urban sci-fi fantasy: Someone is actually building a leafy underground park below Delancey Street on Manhattan's Lower East Side. The Lowline is a plan to turn an abandoned trolley terminal there into a public green space, using special technology that pipes in sunlight beneath the street's surface. The real deal probably won't be ready until 2020, but this week the creators opened the Lowline Lab, a proof of concept and an experiment for seeing the ideas and tech in action. We got an early look inside.
New York's High Line has been an excellent addition to the city's greenspaces, and has really added an extra dimension to urban living. The Lowline could do the same underground. Is transforming derelict industrial structures a better alternative to urban renewal than straightforward redevelopment?

Use funnel-shaped mirrors to gather sunlight into fiber optic, then run that fiber optic into your home, office or indoor garden.

We put a light tube [wikipedia.org] at the top of a stairway in a house we renovated. It made a HUGE difference in light. Even at night it would collect the moon's light and bathe the landing in a beautiful blue glow. I'm a big fan of light tubes now.

You can get even more light at night by fitting your light tube with a fiber-optic path to the ceiling, then using a long delay line to ensure the sun's photons arrive in the house sometime after sunset. With a long enough fiber, you should be able to get a couple hours of extra light.
Now, to calculate the length of fiber needed...speed of light in glass...transmittance...
Well, you'll want to do your own calculations, of course.
