Hi Gordon, “no cosine cubed losses” is an argument among other arguments. Current wind turbines are more efficient than kites for electricity generation, it is all.
And also I sing several songs, including one from a lifter kite/balloon:
Indeed I think an inflatable Sharp rotor combines the qualities of a super lifter such as a high lift coefficient (see here), an ability to operate like an aerostat, and to scale a lot.
Yes. For many reasons, the Sharp rotor should be more investigated as a super lifter kite/balloon.
Sharp rotors could also work in AWES farm in bumper car mode - #4 by PierreB without significant risks of damages, protecting their respective wind turbines below.
Yes. As a result, a high elevation angle is a main feature for a high Power to space use ratio.
