Suggested to observe:
A thermal low-temperature engine. .
In 1986 an application was given for invention. Nowadays there are working schemes of experienced model.
It is supposed that the engine can be made in the necessary size for the settled aim.
The working diapason of temperatures depends on working liquid in the border, if we take water, the working diapason will be from 40 till 96 degrees Celsius. The working interval of the temperatures depends on requirement selection of capacity, and it can be taken in the limit of pointed diapason, for example: 50 degrees approximate coefficient of efficiency C.E is 1,8-2 percent but not higher than to the CarnoТs cycle.

Technical characteristics:

1. working body of liquid: water, kerosene, oils, different gels.
2. intervals of temperature(it depends on working body): water from 40 till 96 degrees. The minimal decline can be 20-30 degree.
3. the optimal decline of temperature 40 degrees.
4. coefficient of efficiency from 1,5-3,6 percent.
5. the sizes are depend on the necessary mechanical capacity to consumer.

Supposing fields of use:

1. water pump for pumping in systems of sunny heating, water supply.
2. water pump from well of different deep.
3. how engine directly.
4. a thermal transformer providing temperature stability of outing liquid of different liquids temperature, the transformers also produces mechanical capacity.

The source of thermal energy for engines work can be:

1.secondary or first not water of headingТs system, systems of engineТs water cooling; turbines, water from different arrangements.
2.sunny energy.
3.burring heat of any carbohydrogenous fuel.
4.smelt of radioactive salts. ††
