Scientists will solve the water problems of the desert and metropolitan areas. Rain-makers will have perfected a simple method, now in the elementary stages of experimentation, for making clouds release their moisture so that the right amount of rain is produced to keep reservoirs at the correct level at all times of the year.
Another method of water production will be the purification of salt water taken from oceans. When a simple, cheap method has been worked out for converting seawater into pure water suitable for use in the household and the manufacturing plant, other scientist-engineers will contribute practical mechanical equipment for piping the water from seashore to desert areas.
Other improvements of the future will touch our lives more closely. It is possible, for example, to imagine that cities of the future will have underground networks of conveyor belts which would supplement subways and make it possible for people to hop on a rapid conveyor system, sit in a little booth, and shuttle a couple of blocks in safety.
Of even more immediate interest than transportation is the clothing of the future. The clothes you will wear at the end of this century may not be of silk, cotton, wool, or even nylon. Clothing will be made of new synthetics and so will the upholstery materials you order by television-phone. To get these synthetic materials, scientists will have devised some electrically controlled apparatus which will allow men to dig twenty miles below the surface of the ground. At that level inside the earth, they may discover many types of rock, now unknown, which will give us these new synthetic materials. Cloth made from these materials will be fire-proof because they come from rock.
