The ground wind power generator of EZEN is using the “Wind Tunnel” effect of its own which is known as Bernoulli principle in Physics to sense and increase the inhaled wind. General wind power generators produce energies from the wind with free directions, but the wind power generator of EZEN rotates by itself in the direction of wind blowing in after sensing the wind and increase the wind to produce more power(kWh). As the wind passes the wind power generator, it is met with board and the speed is increase by being cohered, so more power is produced step by step. By increasing the natural wind speed, more power can be generated on a small footprint. Proportionally, the wind power generator of EZEN has the higher power output with smallest foot print in the field. With such characteristics, EZEN’s wind power generator is the only one designed to produce energies for population concentrated area or places with space limit.
