We have great amounts of:

1. Sea water

2. Sand

3. Sunshine

So we will concentrate on how to transform these into things beneficial to the mankind.

We will turn sea water to domestic water useable for a) irrigation and b) to be consumed by farm animals.
We will find methods to purify the sea water to c) potable drinking water for human consumption.

We will find methods to fight the sand storms and methods of making the sand fixed and non flying.

We will cover methods to transfer sun energy to electricity to power and to be used in the above processes.
