June 15 th 2015: Breaking news :our microturbines have successfuly pass the 200 kmh test. The new rating for one single turbine is : 190 W for 55 ms wind speed.
We can make wind farm that not only withstand Typhoon / Hurricane /Cyclone /tornado forces but generate power during these storms and a lot of it. |
|
|
 |
|
|
Our turbines have a starting speed of 1 ms and targetting low wind speed is within our possibilities.
There is many many places where wind speed is in average between 3 ms and 6 ms.
We can easily tap that energy but the cost is still too high.with 150 000 turbines at 5ms we only generate 150 kW.whether itis Motorwind or conventionnal technology.
Of course all systems have a higher capacity for higher winds but in so many places it happens not very often. To improve the cost there is not many choices we must increase the swipping area whithout increasing the turbine area. |

We have tested a wind concentrator and the results are as expected.We can at least double the wind speed.
It means that we increase our output by 8 times and therefore reducing cost by approx 8 times.
For Wind farm we use a rectangle shape to avoid the cantilever traditionnal design and flaw.
which give us space to accomodate PV panels :
