Wind measurements by LiDAR—how does it work?

Average wind speed increases as the elevation rises meter by meter and reduces the braking effect of hills, vegetation and other ground-based barriers. For this reason, state-of-the-art wind power systems now have hub heights of between 120 meters and 160 meters. The rotary blades that are 70 meters to 100 meters long jut more than 200 meters into the sky at their highest point. This creates a problem for planners: Wind measurement towers are generally 100 meters high.

Why quantum revolution 2.0?

In the first 25 years of the 20th century, it became increasingly clear that elemental particles at times behave like waves and at times like particles. Louis Viktor de Broglie combined Planck’s quantum theory, Bohr’s investigations of atoms and Einstein’s understanding of photons as light particles to form the wave-particle duality theory.
