Kites used to generate electricity

The video discusses wind speed probabilities at different altitudes and their impact on energy harvesting. At higher altitudes, wind speeds and the probability of exceeding certain speeds increase. Doubling wind speed results in an eightfold increase in energy harvested. An experiment using a 20-meter stunt kite connected to a train demonstrates how kinetic energy can be converted into electricity. The kite follows specific flight paths, and the energy produced is significant enough to power thousands of homes, with potential annual production reaching 120 gigawatts.

How much energy is harvested when the wind speed is doubled?

What is the annual electricity production capacity of 24 sets of kites?
