The main content you blocked, in its original form as well as its corrected form, is the following I put again:
[“It odd if you also think AWE progress has been slower than reasonable."
If there is some decisive progress.
“You may have missed lots of past discussion about tether length to kite area and sweep, including at conferences and in papers.”
Indeed I just got acquainted with Dave’s previous message on 2010 on Yahooist Teil der Yahoo Markenfamilie .
I often evoked this concern. I presented “Land and space used” in AWEC2013 (see the attachment).
An example on: https://www.researchgate.net/publication/260586228_Airborne_Wind_Energy_Based_on_Dual_Airfoils :
Page 7, figure 6 concerning the dual-airfoil 10 MW system. Two tether lengths are considered: 8 km then 15 km, involving in land use being respectively about 200 km² and 700 km² !!! Resulting a density of respectively 0.05 MW/km² and 0.014 MW/km².
When the power/land and space use ratio will be considered as I advice it, some progress could occur. Multi-kite airborne wind energy systems (MAWES) - #22 by PierreB and Power to space use ratio .]
Your messages of which one from your forum https://groups.yahoo.com/neo/groups/AirborneWindEnergy/conversations/messages/25789 : “Doug and Pierre are invited to form new topics for specific response to non-AWEC concerns.” say the opposite.
