To choose optimal place for wind turbine, you need to know two basic parameters:1. Vavarage – the average wind throughout the year. The total amount of kilowatt hours of electricity you will get depends on this parameter. 2. Vmax – the maximum po

In this article the necessity of measuring wind at its different heights is discussed. The economical optimization of tower height is impossible without such measurement. In places where land is relatively flat, for example, in deserts or swamps, sma

The electrical resistivity of thin layer (film, coating) about 5 microns’ thick has been measured by the classical four-point probes method. The layer includes titanium-copper alloy grains up to 5 microns in size. Unexpectedly we encountered a phys
