Space Apps Challenge 2017

Desalination is our solution for the environment. As we will exploit the available recourse of water like oceans, seas, salty lakes and underground water to integrate new developments and smart technologies in various domains including (energy, transportation, agriculture and environment).

By using a station made of several devices made of (1-heat pipes) it has two layers. The inner one is consists of copper & Nickle. It is colored in black. The outer one is made of glass to work as blazing glass to stop leakage of heat.by this way it can absorb 94% of sun radiation.

We will use 20 pipes in each device. The dimension of each one is: - 183.5 cm length and a diameter is 5.8cm. It will contain amount of water equal to 73.3 liter.

As we will put the pipes on the ground we will pay attention to the angle between them and the ground which will be 30 degrees.

Those pipes will be connected to a container from the above where the salt water will remain. This container will have a length of 130 cm, width of 25 cm and height of 90 cm. we will put about 250 liter inside it. By using a towing machine which will pull the salt water until it fill the pipe. After that there will be different in pressure between the source of the water and the container so the water will remain to flow of the container as it move from a high pressure to low pressure.

Inside the container there will be a heat spongy. It is consists of two layers (carbon foam, graphite flakes)

• Carbon foam: - is isolate graphite from water and allows the passage of water to evaporate by graphite flakes.
• Graphite flakes: - it can evaporate water by using solar energy. It has many pores to allow the passage of water vapors.

Heat spongy can absorb 85% of solar energy.

As the water evaporates we will exploit the steam produced. We made two inclined planes above the container to allow the steam to condense on its surface and transfer the water across its sides to reach water tanks to get benefit from it in many fields.

Those two tanks have the same size. Each one of them is 150 cm length, 20 cm width and 100 cm height. It can expand about 300 liter.

After that the water in two tanks will be transferred by a pipe to a big tank under the ground.

During transferring the water between two tanks we will put a generator to generate electricity from the flowing water that is going to the big tank which is 2 m length, 2 m width and 2 m height. It can expand about 8000 liter of water to use it in agriculture for example.
