this looks interesting ....

“the flexible, dual layer structure has the ability to close out the cold of winter and wet weather.   it also opens up to allow cool air in and hot air out in summer.

the designer, ms abeer seikaly has thought of every basic need and as a result, the tent collects water as well as provides electric power through solar energy hitting the tent fabric.   this energy is then stored in a battery for use at night, providing renewable electricity.   rainwater is collected in the top of the tent and filters down the sides so the tent does not become flooded.  the tent also has the ability to become a showering facility, with water being stored in pockets on the side and drawn upwards via a special system.”.
