A friend of mine posted this wonderful video on FaceBook. It is a short introductory film about the Island One space settlement concept. This conceptual space colony is also referred to as a Bernal Sphere, after the space visionary James Desmond Bernal, who first proposed it back in 1929 in his book "The World, the Flesh and the Devil".

Nice video.

I'd sure like to see this idea introduced into
television. Cop shows in space. Family sitcoms
in space. Spies in space. Rough tough asteroid
miners. Something. Just get the idea out there.

The Discovery Enterprise: Is an Urban Tunguska Close at Hand?

In the wake of the meteorite explosion in the stratosphere over Russia's
Ural Mountains which detonated with the power of several atomic bombs and
injured about 1,100 people yesterday Friday February 15th, 2013, we ask the
question: Is Urban Tunguska Close at Hand? A possible disaster scenario
where a sizable asteroid or meteorite explodes over or impacts a major urban
center can no longer be treated as mere science fiction whimsy. It happened
yesterday and over 1,000 people were actually injured.

We were just lucky this time around. Next time our luck may just run out.
If yesterday's meteorite were a bit larger the whole city of Chelyabinsk
would have been devastated with a death toll measured in the hundreds of
thousands - A modern day urban Tunguska event but, with a massive death
toll. Asteroids, comets and other space debris do indeed pose a very real
and credible threat to the Earth's inhabitants. Today on Discovery
Enterprise we present two video features: the film documentary Siberian
Apocalypse, concerning the Tunguska event and a short animated film clip
showing the trail and trajectory of the meteorite.
