又水の蒸発は水素と酸素の結び付の特異さから蒸発しにくいとされている。気圧の低い富士山頂などでは沸点は低い。
又、塩を入れると沸点は上昇し１０３℃とされている。
本願は、コンクリート製の土管を直立に積み上げて、その中に鶏の給水給餌器というところの上部の密閉槽と下部の開放容器をホースで繋いで、下部の開放容器内の塩水が蒸発することで水位が下がり繋いだホースの切り口が空気中に現われた時点でこの切り口から空気が侵入し、その侵入した空気の容積と同じ容積の塩水が上部の密閉槽からこのホースの中を降りてくるというところの現象を多用した。
この下部開放容器は、コンクリート土管の中で棚を造るとその棚に３０ｃｍ位の間隔をあけて上方に積み上げることができる。
既製の土管も、密閉容器も、開放容器も機種は色々と既製のものがあるので本願の規模は大きくすることはできる。
使用する熱源は温風を吐出する乾燥器であり、例とはヘアードライヤー６５０ｗｈ、布団乾燥器、５００～５４０ｗｈ、それに減圧用ファン３０ｗｈである。
温熱風の上昇現象をいかんなく発輝させ、採取量をいかに多くするかは、今日即乾布なども多種あるので相当期待できるものとなると思われる。
又性能が優れた揚水ポンプも審判中なので、多少電力量がかかっても、問題は採取量がいかほどになるかなのであり、その用具も今日既製品があるので製作費用もそれほどかからない。

Evaporation of water is said to be difficult due to the peculiarity of bonding between hydrogen and oxygen. The boiling point is low at the summit of Mt. Fuji, where atmospheric pressure is low.
Adding salt raises the boiling point to 103°C.
In this application, concrete clay pipes are piled upright, and a closed tank at the top and an open container at the bottom of a chicken water feeder are connected with a hose, and the salt water in the open container at the bottom is evaporated. When the water level drops and the cut end of the connected hose appears in the air, air enters from this cut end, and the same volume of salt water as the infiltrated air comes down into this hose from the upper sealed tank. I used a lot of the phenomenon.
If a shelf is constructed in a concrete clay pipe, this container with an open bottom can be stacked upward on the shelf with an interval of about 30 cm.
There are various models of ready-made clay pipes, airtight containers, and open containers, so the scale of this application can be increased.
The heat source used is a dryer that blows hot air, examples being a hair dryer of 650wh, a futon dryer, 500-540wh, and a decompression fan of 30wh.
Since there are many types of quick-drying cloths available today, it is expected that the phenomenon of rising hot air will be fully radiated and the amount of collected will be greatly increased.
In addition, a water pump with excellent performance is also under review, so even if it takes a little amount of electricity, the problem is how much water will be collected.

(1) A rotating drum whose bottom is slightly immersed in salt water is housed in the lower container which is stacked in a shelf and is made by winding cloth around an uneven aluminum pipe for duct piping.
(2) A hair dryer (650 wh) or hot air from a futon dryer is applied to one side of this rotating drum, and the seawater-wet cloth dries, making that part lighter, and weighing the other wet part. This drum rotates due to the difference in
The seawater evaporated by this warm air irradiation is always kept constant by the air-water exchange through the hose connected to the upper closed tank. and remove it to the outside.
These lower containers are placed on top of each other at intervals of about 30 cm on a shelf.
(3) An open container is housed in the upper part of the shelf so as to enclose the several lower containers housed in these shelves, and is connected to the upper sealed container by a hose, and the edge of the open container is A piece of cloth is hung across the crotch and the salt water inside always descends.
The inside of the cloth that wraps the whole of the several hanging lower containers is filled with the rising warm air that irradiates each of these lower containers, and this warm air is the seawater that wets the hanging cloth. It passes through the cloth while blowing it off, and it is thought that the cloth should have a rough texture, but the texture needs to be adjusted.
(4) Next, the space between this hanging cloth and the concrete clay pipe must be decompressed.
The installation of the fan for this decompression is as shown in the drawing, but for decompression, the amount of hot air slightly larger than the total amount of warm air is adjusted so that the steam passing through the texture of the cloth is increased. (5) Outer frame Concrete clay pipes are thick and do not get warmed by warm air. It is also cooled by descending salt water in closed containers corresponding to each of the lower containers placed on the top.
As a result, condensation adheres to the outer frame concrete clay pipe, and the processing of the groove to receive the descending water and take it out of the frame is as shown in the drawing. There is also a method of heating with an electric heating tube for boiling water in a sealed container installed on the top of a concrete clay pipe.
It depends on the amount of water extracted and the level of water demand in the area, rather than the amount of power input. It is also impossible to supply 5kwh of electricity in that area.
The higher the altitude, the more useful water is.
In addition, each hose used needs to incorporate a stop valve (cock) for replenishing seawater to the upper closed tank or taking out the amount of sampled water.

Distillation in this upright cylinder was inspired by the noborigama (climbing kettle) used when hardening ceramics. In our post-corona economic management, it is better to focus on preserving the ground environment with a production system of organic matter rather than an inorganic production system of an industrial nation.
In order to do that, it is necessary to send water all over the ground, to sheltered areas, but the energy source for this is electricity.
That is, pumping power to a high water tank.
In addition, the way to the energy creation of hydraulic power itself can be considered as the use of water pressure equipment and the like.

Since our country is a land with large undulations and the water holding capacity is small, the utility of the present application is great if water can be raised to a high place.
Submission of a water pump with good performance is desired.
Whether it is a clay pipe, a closed container, or a rotating drum, there are many ready-made parts used in the apparatus of the present application today, so there is no need to make new ones from scratch.
Also, the electric appliances used are a hair dryer (65 wh), a futon dryer (500 wh), a decompression fan (30 wh), etc., and the total power consumption is 5 kwh.
In addition to these, 2 kwh is required as a water pump with good performance, and a total of 7 kwh is required. In order to deliver this to the water craving area, the supply of the above electric power is indispensable.
The daily output of fresh water is 20,000 ^m3 in the above case.
It is easy to expand the scale of the present application if we can find a way to supply the amount of power required for this production.
As noted in 0007, electricity is also hydroelectric power generation, and if there is water, there is also the creation of energy through the use of hydraulic equipment.
