This is a description of a sun water pump, for
the drive of which, a power element made of
nitinol with the shape memory, is used. Such an
element changes its shape when it is heated up,
and when it cools down. It is heated up by the
sun rays, and it cools down with water or after
being shadowed by a curtain. The power
element’s shape change is used for the pump’s
drive or any other device.
Millions of Russian citizens like to work in their
gardens. And that means that together with the
other gardening stuff the watering of the garden
plants needs to be done too. The water for that
may be pumped with an electric pump from the
garden well.
But unfortunately, the electric power is getting
more expensive. That’s why the question about
searching for the new ways of energy saving
stands very sharply, both for the big enterprises
and for an individual alike.

A pump for the water lifting from a well at the
sun’s energy expenses is mostly wanted. It
would be very good if such a pump, attached to
a well, in a dump, cloudy weather does not work
and keeps its motor’s resource, because the
garden watering is not needed in conditions like
that. It is not bad, when in a hot, sunny weather
the pump starts working by itself, collecting the
water for the evening watering. And it should
work independently, always when the sun
shines, without any man’s intrusion.
The hotter the sun’s heat, the more water is
needed for irrigation; and the pump must work
more energetically the whole time, in order to
supply more water.
Such a fascinating pump is attainable to make.
The main knot of a pump like that is the power
element, which is made of metallic alloy with
the shape memory.
The first time in history alloys like that were
produced about 60 years ago. However, at that
time they were made on the basis of gold; and
they did not find any practical use then, because
of their high prices. Later the shape memory
alloys were produced on more accessible metals’
basis. Some of those metals are known at the
present time. One of the most accessible is the
alloy of nickel and titanium mixed
approximately in equal proportions. An alloy
like that is called nitinol.
These alloys’ specialty is in their ability to
jumpily transform their shape during a heating
up to the determined temperature. During the
cooling, an element made of nitinol alloy gets
back to its original shape. This happens, because
of the alloy’s atomic structure restoration. The
forces, appearing for the duration of this, are
