High Altitude Wind Power

At any moment, the winds in high-altitude wind  roughly holds 100 times more energy than the entire  electricity consumed in the world. High altitude wind power: High altitude wind power is one of the useful energy that is captured in the sky by using tether and cable technology. The atlas of  High altitude wind power marked is prepared for various regions of the earth. The spinning rotors of the kite turbines will convert the kinetic energy of the wind in to electricity and return it back down, through the wire 30,000 feet to a distribution grid on the ground.

I like to share this Definition of Electric Current with you all through my article.


High altitude wind power


Different methods are used to capture the kinetic energy of wind in the sky by using kites, apostates, gliders which are fitted with  turbines, Sailplanes with turbines etc. At higher altitudes Winds are stable, continuous,  and have higher velocity. Before installing wind turbines, wind source evaluation is done. The energy available in the wind is proportional to the cube of its speed, which means that doubling the wind speed increases the available energy by a factor of eight and tripling the velocity gives 3*3*3=27 times the available power.


Advantages of high altitude wind power


At higher  altitudes wind is continuous and strong
Flying electric generators can achieve up to 80 percent of availability by placing them at suitable location
High altitude wind generators can be adjusted in height and position to maximize energy return, which is not possible in case of  fixed tower-mounted wind generators.

Is this topic Physics Work Equation hard for you? Watch out for my coming posts.

Some of the challenges to harness high altitude wind power are


Increase in the altitude leads to  increase in  the length of the tether, temperature of the air increases and the susceptible to atmospheric lightning.
High altitude wind power, increases the cost and exposure to turbulence
Very accurate systems are needed to maintain the position of the turbines in the sky
Difficult to inspect the systems
Chances of collision with  flying jets and planes and birds
