 Floating Buildings
</h3>

 Posted: October 10, 2013



 RUTGER DE GRAAF (Civil Engineer):
 
 And here you can see the three connected domes. Two of them are transparent.



 NARRATOR:
 
 This geodesic pavilion floats in the port of Rotterdam.



 RUTGER DE GRAAF:
 
 I think a floating city might be the safest place to be if there’s a hurricane or flood. That’s the place where I would go.



 NARRATOR:
 
 Rutger de Graaf runs the firm that designed the pavilion, which hosts conferences, performances, and parties.



 RUTGER DE GRAAF:
 
 So it shows that it’s actually possible to make large buildings that float on water, and as such it’s the first step towards creating collections of floating buildings and infrastructure, which in the end will lead to creating floating cities.



 NARRATOR:
 
 He calls it a blue revolution. Eventually, he envisions self-sustaining cities in the middle of the ocean.



 RUTGER DE GRAAF:
 
 I think we’ll definitely live on the oceans before we are going to live on the moon or Mars.



 NARRATOR:
 
 It seems far-fetched and it won’t be all clear sailing. At Delft, a developer built these two floating homes way out of balance. One is listing badly. The other is level thanks only to 6500 pounds of water stored on one side of the basement. They are looking for a more permanent solution.


 Keeping their feet dry has always been a Dutch priority, but the key lesson they have learned over the years—simply fending off the water as if it were a mortal enemy is like tilting at windmills.

Colossal explosions shake a remote corner of the Siberian tundra, leaving behind massive craters. In Alaska, a huge lake erupts with bubbles of inflammable gas. Scientists are discovering that these mystifying phenomena add up to a ticking time bomb, as long-frozen permafrost melts and releases vast amounts of methane, a potent greenhouse gas. What are the implications of these dramatic developments in the Arctic? Scientists and local communities alike are struggling to grasp the scale of the methane threat and what it means for our climate future. (Premiered February 2, 2022)

In the Arctic, enormous releases of methane, a potent greenhouse gas, threaten the climate.

Scientists have cured a handful of people of HIV by piggybacking on treatments they received for blood cancer. But does that bring a widespread cure any closer?
