Very nice thinking to overcome low speed wind, as increasing blades number will increase solidity by ratio, accordingly power too. I have some questions: 1) How to get the power curve of two counter rotating turbine? 2) How to calculate the energy output or AEP accurately(MWh/y) of a group of this type of turbines . 3) Did you use WAsP program by RISO of Denmark for a wind farm ? or you used a simple xls sheet? 4) How far your applied new turbine capacity (kW) commercially in Thailand by now? farmers like it? 5) how about adding wind lens too, it will increase wind speed (may double!?). waiting for your explanations. thanks from Egypt. best regards.
Use stronger magnets in the stator and combine the two counter rotating propellers into one to overcome the increased torque. Show me that this will not be equivalent to what is proposed. Also, the propeller behind will be in turbulent airflow from the propeller in front. Not efficient.
I thought about it as well, verry smart thinking sir and there is a more effective way to do so. The solution is not in 2 counter turning blades in this way, but there is a smart Tesla way.
The biggest problem you're gonna have is you need to rotate the statter at the same speed as the rotor otherwise you're gonna have variant voltages. And with wind that Can be very difficult because wind isn't stable
i doubt you invented counter rotating wind turbine, Your not the first. Inventions presupposes being first. What you did was make a design of your own involving the same invention of others,
Nah. It's not something great. It's already an old concept. Many dis this before you. It so happened in your country nobody did it before. Do something original period.

Awesome!
Add coils inside and outside the rotating magnets to produce more energy output.

Wayne Yeah man 5 years ago built a generator that the stator spun opposite the rotor. It's called the "Differential gear generator"
This is so cool
Good idea!

tested and working
สุดยอด
Old technology..I have derived mathematical formulas for calculating power content of CRWT
Show me where we use it...
Could you explained about your mathematical formula
Not so good because of differential wind flow because of rotation
No if charge batteries
