Water wars…By 2025, global water demand will exceed global water supply by 56 percent. That’s a lot of dry mouth, and if you think people are overly willing to shoot each other in the head for oil, imagine what we’ll do for water.
Too much water and none for drinking:It’s not like there isn’t any water available; the planet’s lousy with it. There’s just the pesky issue of all that salt in the planet’s oceans (which make up 97 percent of the water available on Earth. Two of the other three percent is locked up as ice). Drinking seawater increases the levels of extracellular sodium around cells. To maintain equilibrium, water rushes out of cells to dilute the sodium, leaving cells — and ultimately, the drinker — dehydrated. So drinking seawater’s out.
How to make water fit for drinking: We can remove the salt from seawater, leaving only nice freshwater, which does a body good. Right now, the most widespread method of desalination — reverse osmosis, which captures salt via membranes — is expensive and consumes tons of power. There are new, clever methods hitting the scene. One is the Solar Cube, a portable water desalination plant that uses photovoltaic cells to power salt removal and capable of pumping out 3,500 gallons of freshwater per day. Even more neat-o, the Solar Cube also generates enough electricity to run other stuff, like a laptop.
Solarcubes in Pakistan: Solarcubes provided drinking water and electrical power to several villages in Pakistan after the major earthquake in 2005. Currently, the Solar Cube is being used in isolated villages in Venezuela, and Pakistan.
How a Solarcube works: The Solar Cube works by placing a pump, which is attached to the machine, into a polluted water or salt water source. The water is pumped through a series of filters to remove large matter. At the final stage, the water is filtered through a reverse osmosis membrane, which is so fine that it dispels all bacteria, viruses, salts and dangerous chemicals.
Power for the Solar Cube’s operation is generated by 24 volt batteries which are charged by both the integrated photovoltaic solar panels and a wind powered generator. Once assembled, the system is easy to operate, cleans its own filters, and has a service life of at least seven years, the companies say.
Hmmm….looks like this can be a solution to two of our future problems, water and electricity.
Humans have been using solar energy for thousands of years like drying their clothes with the help of sunlight. Using it for electricity and cleaning water is a good concept but the equipment used to capture solar energy is too big and it occupies a lot of space which can cause problems. Another thing is that solar energy is not that efficient as compared to fossil’s energy.
The most important is how to use solar energy better.People need cheaper and clean energy.Who stop it to develop fast. We know it can do more thing than we looked.I am working a solar energy factory in China. If you use it ,must through factory-trader-nativetrader-distributor and you.In factory we made it must spend 2.3?/w.But i don’t know how much somebody buy it in us and euro.In fact the most expencive of systerm is cells,in China maybe just 10 company control the markets.
