Future cities will float on water

It may seem like science fiction, but as rising sea levels threaten low-lying nations around the world, floating cities may become more common. This is the american scientist’s argument to rise money to build such SF cities, writes The Guardian. 

 

The Seasteading Institute proposes a series of floating villages – and claims to be in active negotiations with potential host nations.

At first the villages would aggregate in protected waters. You could extend an existing city like London into the water quite far before ever being seriously challenged by infrastructure issues. Later, they would cut ties with land altogether.

Redefined Door Design - Evolution Door by Klemens Torggler

The door has stayed the same for a really long time.
The standard door becomes  pretty boring: some material (typically wood) on a hinge that opens and closes a gap of the same shape, either between two rooms, or a between a room and the outside world.

 Austrian artist Klemens Torggler decided that the door needed a facelift so he designed this four-panel prototype that flips out of the way to open, and flips back to close.

Torggler calls this system a “flip panel door” (Drehplattentür). The Austrian has a few variations on this door, one with the origami-esque triangles that fold out to help the door move, and another system with rods that rotate two square panels.

Currently the door is meant as a prototype, an extension of his artistic practice where Vienna-based Torggler has been creating similar kinetic doors for many years, several of which are available through Artelier Contemporary.
