The word "maglev" (for "magnetic levitation") is familiar from the area of transportation, where maglev trains provide faster and smoother movement for less energy cost than conventional trains. The same principle works to enhance wind turbine technology, too.
Efficiency is an important consideration in energy technology. Energy always comes from some raw source — chemical reactions, sunlight, kinetic energy, nuclear reactions — and is usually converted into some other form of energy before being used.
Despite the fact that governments and businesses in more than 80 countries are embracing wind power, and more and more wind power is providing bringing new, clean and affordable energy every day, some people have concerns about wind power.
