Free fresh water for Islands & Africa

fresf water is free

Islands lack the large open areas, required for the catchment of natural rain fall.  A any case hot Ireland's do not have a lot are rainfall!  They have incomes by engineers, by expensive higher pressure filtration, or old fashioned boiling!  Both or which have a energy expensive.  We use a little 20 kW solar panel

There is a far simpler idea!  We were all shown in high school physics.  We use a little 20 kW solar panel, or a core countries are little wind turbine.  Week in charge up the battery to carry us to the dark of night or during a windless period.

We drop a snorkel into a local river or even the sea.  And we exerts one W of pumping pressure, equivalent to one metre of vacuum.  By definition!  The water by definition boils.

Losing all salts or heavy metals and contaminants.  These flow out of the snorkel, as cold brown water.  We just pump out the purest water vapour!  Which we transport to the little holding tank or reservoir.

Week he then use as water to irrigate the crops.  Or even drink!  Though it will be totally tasteless.  The hot countries we need salt tablets.

We have Water Aid from medicine remote well drilling and fabia liquid water.  Which is actually a Roman idea!  It is expensive and requires significant pumping.

The vacuum desalination idea uses an environmental waste energy.  Like a little solar panel in hot sunny countries.

And he Africa are groups of farmers can set up a vacuum desalination unit, to freeze the water to irrigate the fields.  I was shown nurse at Bolton school 1978.

The idea of a low pressure evaporation water, came in with the development of the steam engine and late 18th century.

Here we use it to free use pure water vapour from brown river or sea water.  For use in the cleanest totally pure water there is.  For very nearly free!

Water Aid caring get their act together and free use pure water for the whole world in six months!  There are have eyes that will save.  Any global drought and famine at a stroke.

Higher pressure desalination is both energy expensive and dawn dangerous!  They very radio change of the filtration pounds.  The vacuum desalination we do not have a filtration bad.

The boiling of the water drops all contaminants!  An weather features totally pure water vapour.

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
