cost free Water for Africa

free fresh water

The seas are a limitless source of water.  And removing the salt is stupendously simple.  And very very inexpensive.  We use a highly school physics.

We drop a weighted snorkel into the seas.  To below the wave height!  We then attach solar powered vacuum pumps, one close to the sea will suck of the seawater by one metre.  By which state i has boil off!

We then have a chain of solar powered vacuum pumps, to carry the water vapour inshore.  To over the first set of hills, or where ever we want the water.

As he vent the vacuum, the water vapour forms a fine water mist.  Which is so cool!  And will condense into larger and larger water drops, and so it settles on the ground and plants.  Just like natural rain fall.

As the waters of boiled off, is has left the salt behind!  To sink into the seas hours concentrated brine.  We just get out pure water.  With no salts, who is cells all contaminants in.

It is a sort of science that Water Aid should be implementing.  We can use this idea all around the world - where we have access to sea or river water.  We suck into the purest water imaginable!

Just 1 W of vacuum will cause see water to boil.  At 1 a second.  We have access to is so much free fresh water.

No or high pressure or high temperature desalination required.  We have no need for expensive engineering plants, no regular filtration pad changing.  And it is so safe and non dangerous!

Let it flow This idea works all around the world!  It is especially important for dry and arid countries, like those in the Middle East. We really want a source of carbon zero electricity.  Luckily this is amazingly easy!  We use a high voltage electronics from a all fluorescent light, to fire up A steam plasma in a glass cylinder. My American friend firm that a 30x1.5cm steam plasma gave off a constant 1 MW of heat.  This all came into the comments of professor Z 2001, that the turbulent flow of steam did nuclear fusion!  What professor Argent turmed molecular nuclear fusion, 1 H₂O+P+TU→He²⁺+O⁺+3e⁻ so setting up a steam plasma is the simplest way to get a carbon zero heat on earth.  It is how the Corona is around radiant sun's they've rates heat light and X rays.  From a hydrogen plasma. My American friend was very proud of his work. 2 H₂O+PL→2(E²+L+X-ray) so a constant 1 MW of carbon zero heat.  Which to be honest P's rather too much!  So we utilises a 15

Water Aid has missed a tricky here.  Well water has arsenic in it! Drinking water standard The maximum level of arsenic the U.S. Environmental Protection Agency (EPA) allows in community water systems is 10 micrograms per liter (µg/L*). However, consuming water with arsenic at levels lower than the EPA standard over many years can still increase your risk of cancer. As a result, the EPA has set a goal of 0 µg/L of arsenic in drinking water. It is as hard to remove the arsenic, as it use to remove heavy metals and bacteria from river water.  Are it is as simple to remove contaminants, as it use to purify one walls are back in from miles away! In the African Village we really want a source of carbon zero free electricity.  We fire up a 30x1.5cm steam plasma, and get out a constant 1 MW of carbon zero free heat.  We can hire a half megawatts steam turbine for just 1250 UK pounds a month. The UN should have learned to the African Village that money!  They cause the turbine will pro

Wetting the Nahib desert

We are back to my old idea about vacuum desalination!  We drop snorkels into the Red Sea, connected to little solar powered vacuum pumps. We only need to raise the sea by one metre, and it boils into water vapour!  Probably only at 80 cm.  It isn't 1000 times easier to pump as water vapour than liquid water. So we transport it a kilometre inshore, an event the water vapour over the arid desert.  It forms a cooling mist!  Which are like condenses into rain droplets and falls on the ground. There cease in the soil will go crazy!  We may need to distribute a soil dust.  And the plant's will grow like mad.  Sucking in all our carbon dioxide physics is so bothered about! Biology is not remotely concerned.  As plasma photosynthesis on land and sea it uses a carbon dioxide levels to just two parts per million around the temperate earth.  Carbon dioxide levels are higher above the deserts and the arctic ice. In the arctic winter we have four PPM carbon dioxide in the arctic
