HULL CONSTRUCTION

Temperatures vary between +120 degrees Celcius and -160 degrees Celcius. The cosmic rays and solar particles are lethal.

A 50 centimetres thick hull shields the interior from this onslaught. It consists of two outer layers of moon rock and a 35 centimetres layer of water, held between glass panes. By placing to panels horizontally, gravity presses the panels together, which assures airtightness. The encapsulated layer of water absorbs energetic particles and helps to keep the temperature constant. The outer layer of moon rock provides additional protection. Windows are formed simply by cutting holes in the rock layer and replacing rock with glass panels.The towers have a U shaped hull. The inner facade of both the towers is transparant, in order to create tension between the towers. Visitors can look from one tower all the way up to the other tower.
