| The Green houses recycle their water by condensation of plant's misted air |
It makes no sense to occupy the desert without dealing with the problem of water? There is water in the desert, but not sufficient for sustainable occupation. The idea here is to draw a small amount of initial water (using a drill, then closed) to use for watering a farm garden, and collect for recycling in a closed cycle. For this, a simple system operating by convection and condensation, retrieve the moisture in the air, moisture created by the natural evapo-transpiration of plants. This wet air is condensed, water is again recovered to water the garden.

| The stations are autonomous and scattered through the Grand Desert |
In Dune (Frank Herbert, 1960) Fremen is a group that survives in dune desert by using waterproof clothes which recycle their water produced by their bodies (urine, sweat, exhaled air). Our installation has the same process.

| Plantations are growing and watered through the closed cycle of the green house |
To operate independently , we use a system of ” refrigerator space ,” it is an ancient, used for a long time to refrigerate water in hot countries. Insulate a pot of water of its surrounding, the water will exchange their warm with the most cold thing in the universe: the empty dark outer space at -270 ° C by thermal exchanges.

Why cool to recycle water? Plants breathe and perspire, it creates moist air. If you leave this moist air escaping into the atmosphere, you have lost the water. If you recover and recycle, you can reuse it to water and grow new plants. As in the desert Fremen of Dune, you initiated the recycling of water and you can live a long time in the desert.
How does the system work? Plants (fruit trees, gardening) grow in a remote shell on the outside. Watered by an initial amount of water from a borehole (subsequently closed), these plants grow, breathe, sweat and create moist air in your envelope.
This air is recovered by natural convection in a tower that houses, among other things, the fridge space. It through the cold created cools the air, which condenses the water contained therein. This water is recovered and returned to the sprinkler system, drip, which winds into the ground. The cold air generated is used to cool the tower (which also houses the local housing and storage). It also cools the hot air from the outside, a system supported by Canadian well.
The envelope is composed of a large excavation in the ground, that allows for thermal control of the incidental soil. The excavated soil is used to hold a peripheral ring sui supports a waterproof membrane, which lets light in sufficient quantity to grow plants. Overheating is prevented by the thermal regulation of the land and fresh cooled air from the outside. Simply spread on the sand membrane reduces solar gain. It is also possible to combine it with sunscreens supporting photovoltaic panels for electricity power station. The agricultural products are also dried (dried fruit, dried vegetables) to recycle water and allow a reduction of their weight, so better retention and lower cost for transportation.
Bathroom, kitchen, everything is recycled and goes back into the sprinkler system. Organic waste and dead plants are transformed into compost to feed the soil fertilizer. Dead trees are dried to remove water before being used as fuel natural.
The station is about 3 hectares, sized to accommodate 8 to 12 families, which can then feed, and export part of the production. The implementation is done by units, aggregated or isolated as a camp in the desert, in order to create a set of autonomous stations, trading them the necessaries, exporting even in the rest of the country the surplus production.
This project builds, besides Fremen of Dune, the Arecibo telescope (Puerto Rico) and its magical space underneath the film The Powers of Ten (1977 by Charles and Ray Eames), which connects the infinitely large to the infinitely small.
