|Exhibit highlight||1. Trial products of bearings are exhibited.The friction torque of the bearings are improved smaller.
The purpose is to improve the starting performance of a VAWT.
There are two kinds of trial products, DG type and AC type.
The difference of the performance of the present ones and improved ones can be checked with an easy experimental device.
This bearings can be used widely besides a wind turbine.
This bearings can demonstrate the energy-saving effect in the wide range.
2. Exhibit the trial production model of the VAWT of a new form.
The measures against gust which are another weak point of a VAWT are taken.
The measure against a gust can carry out delay-less operation.
A VAWT changes with the two above-mentioned measure technology.
In installation on the ocean, it can suggest that a VAWT is more overwhelmingly than a HAWT economical.
