The next fair of ideas, technologies and projects organized by the Ministry of Economy, the Ministry of Foreign Economic Relations and Trade and the Coordinating Committee for Science and Technology Development was held in Tashkent on 19-21 May 2015. . The Cabinet of Ministers of the Republic of Uzbekistan.
PROON's PMGEF Small Grants Program in Uzbekistan took an active part and over the course of three busy days highlighted a number of interesting and promising technologies and methodologies that have good potential for implementation within PMGEF projects.
Among the innovations of young scientists presented at the fair is the development of a spiral rotor wind turbine by Bobur Nigmatov, a student of the Tashkent State Technical University named after Abu Rayhon Beruni (Faculty of Energy).
Wind turbine prototype
The spiral rotor project is a further upgrade of the wing wind turbines. The new design uses the force of air flow pressure, as a result of which the initial wind speed decreases to 1.5-2 m / s, and the wind efficiency increases due to the complete coverage of the throwing area - (area). the wind current that the generator blades cover during rotation). Due to the use of molding technology in production, the cost of the product is reduced, and quality and efficiency remain unchanged.
It is also planned to install a disk generator that will allow direct connection to the rotor shaft. In general, a wind power plant based on spiral rotors is more efficient when operating with a shorter self-discharge time. The developer is currently preparing a project application for the PMGEF preparation project.

Subsequent development, if successfully tested, can be applied in the field of combating soil degradation and erosion. We are talking about the technology of stabilization of moving saline sands, said one of the developers of the method at the fair, a graduate student of the Faculty of Oil and Gas of the Tashkent State Technical University named after A. Beruni (ecology) Sevarahon Khodjaeva. This method was proposed by co-authors on behalf of associate professor Sh. Kuldasheva and student S. Rustamova.
The essence of the technology is to combine saline sands using complex additives of reagents and industrial wastes, which help to form a strong water-resistant structure (a shell capable of holding the root system of plants) in small layers. sand along with phytomelioration. The technology combines chemicals with sawdust containing cellulose, which has coagulation (thickening or thickening) properties. involves the formation of

This development has been tested in the laboratory, but to confirm the sustainability of the technology and its advantages, it must be tested in real, field conditions of saline soils, for example, in the Aral Sea sands (dried soil bottom). Aral Sea), as well as in Khorezm and other areas where the soils are prone to salinization. The developers estimate that the use of this technology will allow efficient use of salinization and eroded areas, as well as a sharp reduction in sanding and salinization of neighboring fertile lands due to wind erosion.
If the technology has the necessary preparation and calculations, it is possible to get help from the PM GEF Small Grants Program to test it under the project.

The fair presented a number of interesting ideas and developments from the country's technological universities:
• Urgench State University presented to the guests and participants of the innovation fair the technology of automation of moisture control during irrigation in agricultural fields in order to prevent overuse of irrigation water. This technology has not yet been tested on the experimental site. Once tested by the developers, the technology can be offered for design review at PMGEF.
• A group of scientists from the Namangan Institute of Engineering and Technology came up with the idea of creating a solar lens heater to heat individual homes. Cost and benefit calculations need to be done to present this idea for project development at PMGEF.
