A few basic problems create great suffering and tragedy. According to the World Bank, water is one of the great concerns of the United Nations. Almost half of the world's population does not have access to a basic sanitation system, and almost 1.5 billion people do not have access to clean, drinking water.
Of all the water consumed in the world, 67% is used for agriculture and 19% for industry. Domestic use counts for less than 9%.
Molecular manufacturing could replace a large percentage of industrial production. Much of the agriculture could be transferred to greenhouses. Domestic water can be treated and recycled.
By taking these steps, you could reduce your water consumption by at least 50% and probably up to 90%.
Water-related illnesses kill thousands, perhaps tens of thousands, of children every day. All of this could be prevented with basic technology, technology that can be manufactured very cheaply if factories are cheap and portable.
Molecular nanotechnology can offer similar opportunities in many other areas.
Today a lot of water is wasted because it is almost, but not one hundred percent, pure. Simple and reliable electromechanical treatment technologies can recover contaminated water for use in the agricultural sector or even for domestic use. These technologies require only initial fabrication in addition to a modest source of energy. Physical filters with nano-scale pores can remove 100% of bacteria, viruses and even prions. An electrical separation technology that attracts inoesa supercapacitor sheets can remove salts and heavy metals.
The ability to recycle water from any source for any use could save enormous amounts of water and allow the use of previously unusable water resources. This could also eliminate the "downstream" type of pollution; In other words, a totally efficient water filter is capable of assuming the regeneration of "dirty" water from agricultural and industrial activities. As long as waste is controlled, water can be filtered, entered, and even purified and used profitably.
As with everything built through molecular nanotechnology, the initial costs of manufacturing a water treatment system would be very low. The cost of energy would be low. Well structured filter materials and small actuators would allow even the smallest filter elements to be controlled and cleaned. Fully automated self-contained filter units could be integrated into scalable systems over a large field.
