I am obsessed with water! Most people who do not have any usually are, we do not have any supply, no well, we depend on rain water or purchasing deliveries. In southern Catalonia about a Kilometre from the great river Ebro it seldom rains. Around the end of March into April, then late September and early October a few rain clouds reach us. To do this they have to travel right across Spain, we used to get summer storms but of late we get a large amount of thunder and lightning but very little rain.
We have a cisterna in which rain collects but it is never enough, two or three deliveries are required each year plus our visits to local public springs. We do not have agricultural water in this area so my mind often wanders towards finding a reliable source of water. The easiest option would probably be to have a well drilled, but the cost is some what prohibitive. Running into the tens of thousands, by the time you add together generator, pump and pipe work at least twenty thousand plus you are never totally secure. The local water supplier might turn up claiming that your water has come from his ground water supply and you end up getting charged for it.
Every so often I look around for alternatives. Surely technology should be able to come and rescue me, there is a possibility AIR WATER GENERATORS. These machines extract water from the atmosphere, the conventional models use a refrigeration compression system rather like a de-humidifier, the only down side is the amount of energy required to operate these systems, putting almost as much diesel and petrol in as you get water out. But large industrial units are in use around the world. Some Indian villages depend on these machines for their clean water supply, newer technology involves the use of desiccant, which collect water and then extracts it, lower power use but still fairly expensive, $12000 for a small system, but they are getting there.
I am surprised that charities who operate in the drought areas of Africa do not have industrial sized machines on the back of lorries, which they could take to specific countries. This would prevent vast numbers of refugees wandering around building up giant camps, they could solve the problem at its source, and if food was required it could be supplied in manageable quantities. However that does not make headlines. If you can say this is the largest refugee camp in the world, wow what an impact. But, if like me you have seen that headline for most of your adult life it some how loses any great value. How many millions of adverts have you seen, the dying child, malnourished, I do not see its starving parents. Ethiopia, you must surely remember one of the first great famines out of Africa, but that country is now the largest recipient of food aid in the world per head of population. That is not solving a problem it is just making a bigger problem which will explode much later in the future, that is a dependency, not a vibrant country striving for its improvement.
If the hackers of the world wished to really do something of value to Africa and the World here is a problem to solve. Break in to all the bank accounts of all the dictators, corrupt politicians and military officers and transfer the money to the RED CROSS, they would be able to feed Africa for the next hundred years. But nobody really wants to solve that problem it would put all the charities out of business.
The American Government understands the importance of fresh water, during Katrina they had giant industrial water generators making water in New Orleans. Now they are in the process of having battle field water generators produced, I believe, by Boeing. But water is an economic weapon the same as any other commodity without it you die, however all around us in the air we breath there is water, for which there is a market.
