fresh water for the dessert

free fresh water

There is loads of water vapour in the air - which is to create two precipitate out the water.  Which is why caves often have a central pool full of water!

The rocks became a cold other night, and receives a water from the daytime air.  So we need to freeze cold in the heat!

We already know how to do this.  We run a car no refrigeration cycle, and we pressurise an vent a gas.  The low pressure gas is cool - so is a source of cold.

When we pressurise the gas it gets mad hot!  The ambient temperature plus 253 degrees C if we double the pressure of the pure gas: we neither gas with no water vapour in - nitrogen is very cheap and totally suitable.  The gasification people through the nitrogen away!

So we pressurise the gas and lose their heat to the high atmosphere.  Then when we vent the gas low down, we produce a regional so a massively cold air.

And the water vapour precipitate out!  Collecting in a pool.  It is pure water - no contaminants or salts.

And over time the cold air and hot gas makes, to freeze the regular air temperature we have today.

We have just borrowed some cold to precipitate out water.  Which we collect and bottle.  And in hot countries there is loads of sell our power to drive a little solar panel.

Give us access to the free electricity we need!  In Africa are we produce water, and the power to heat the village.  We convert the DC current into mains AC.  For convenience - week and then drive a commercially practiced electrical devices.

Only now we have access to almost free pure water.  No all well drilling of 5 feet water for hundreds of miles.  Nature provides the moisture rich air for free!  To where we need it.

For the little car no refrigeration trick, produces a little region of cold air.  There precipitates out our water!  Which is so very nearly free.  And he works fantastically in hot arid lands.

So water age should be providing little solar panels and a Carnot refrigeration pounds, which are massively cheaper than a drilling remote water boreholes and piping in the water.

So Water Aid has access to some the greatest minds on the planet.  Who must instantly grasp this idea!

We crimp for the end of the metal sheet, so all the water runs into the middle of the heat.  Then drips out into collecting part placed on the ground.

This idea came from my father's life saving army training, in Kenya in the 1950s.  So we we are out there metal sheet at night, having carefully covered during the day.  Arranging the cold other night, we will collect all the water we need for the next day!

Provided by nature for free!  We pay for a metal plate, and the stand!  And the metal work to form the collection system at the base.  This is not hard science!

Any village blacksmith can make the water service.  It is about as low tech as it gets!

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
