WE ALREADY HAVE COUNTLESS WIND TURBINE DESIGNS. WHY DO WE NEED ANOTHER ONE?
The answer is simple:
EFFICIENCY
Why is efficiency so important?
Any device capable of moving under the influence of air flow can convert wind energy into other forms of energy, such as electrical energy. So, we can build whatever we want, even something like that:
This device can generate electricity if an electrical generator is attached to the rotor. However, to produce a comparable amount of power, a low-efficiency turbine would need to be…
EXTREMELY LARGE !!!
Why?
In theory, we could capture 612.5 watts from 1 square meter of the area that wind passes through under standard conditions. However, according to Betz’s Law, we can only capture 59.3% of the wind’s energy at best. This means that from a 1 square meter area, we can realistically acquire just 363.2 watts with an ideal wind turbine. If someone claims they can create a 1 square meter turbine with a rated power output greater than that, it’s a scam!
The rest of the explanation is straightforward: If we have a wind turbine that is half as efficient as a reference turbine, we need to build a rotor with twice the area of the reference turbine’s rotor to generate the same amount of electricity. This usually means, at least, double the materials, triple the labor and logistics costs, a significantly larger support structure and foundation, higher maintenance costs, and a greater visual impact—all for the same amount of generated electricity. Therefore, the real performance of any wind turbine is measured by the amount of energy it produces over its lifetime versus the overall cost of the turbine:
