Amazing presentation Markus. I usually don't write a comment, but this was truly a straight-forward, well-communicated and understandable presentation.
icing is an interesting question. i was whether kites (fabric) or fixed wing deal with it better. the fabric, as it changes shape (perhaps we force more flexiing than default given icing conditions) , might break off the ice. i'm sure there is lots of existing research on wind turbines and also planes that might apply to fixed wing scenario.
Thank you Markus! That's really awesome presentation and loved the idea! would like to explore more through articles and if any practical implementation ?
i wonder if it would be useful on the tether, every so often, to have a wind speed / direction sensor -- i imagine they could be made incredibly small and light. This will give you a lot of dynamic information. Well, for lower altitudes anyway. of course other approaches exist such as LIDAR or just doing a big swoop down and back up to get data. but if we had a sensor every 100M on the tether, and the device is sort of circling, you will get a pretty good 3d picture of the wind conditions for your cone. Another idea, harder, get super fancy and try to "watch" (with cameras) the curvature of the tether, bottom to top, in all axis and that would imply certain winds at certain levels -- watching for variations in the arch of the tether compared to say some modeled tether shape given no wind or constant winds. This seems like a nontrivial math problem but not impossible, unless the tether shahpe variations from wind aren't significant (ironically the better your tether (thinner) the less this idea works). i suppose even then you could have tattletails on the tether ever N meters and "watch" them (with a computer)? sensors likely more practical and works in the dark.
if you have helium Balloon you don't need to use wind power you can get all the energy you need from the lift itself. just like a swim bladder you use leverage to control ascend and descend. when balloon is far up in the atmosphere a small mass fall pulling a rope from the balloon turning a compressor that compress helium from the balloon until the balloon get so heavy it begin to descend. the upward movement and downward movement can use turbines to generate electricity. a station on the ground could generate a upward lightning strike to a antenna with downward polarity on the balloon and the descending or ascending motion the turbines charges a big battery let say high voltage battery and power flow in then transferred trough lightning strikes into that charges a giant capacitor or battery on the ground than then is connected to a grid tie system. on the descent the balloon need to have enough falling speed so that the rope of the mass hanging under it when hit ground the helium balloon can then reach ground level and be temporarily tethered so that the inflation of the balloon can turn a small turbine that then rewind the rope and the balloon can once again ascend. since the pressure of helium only act to lift the rope at ground level the energy required is less since the mass that use leverage is resting on the ground. this way simply by ascending and descending the balloon as i described you can extract as much energy from gravity as you want completely free cost zero. the balloon itself and technology onboard would be the only cost. turbines or complex propellers can be made foldable with counter weights so no energy is needed to change from ascend to descend stage or can also be static patent pending. the balloon need to reach stratospheric altitude to extract huge amount of potential free energy from gravity.
I predict this is a dead end technology. With price per kw dropping for stationary wind gen, & solar, striving to compete at the envelope edge is an uphill task.
Well done! Nice presentation. Is there any way I can get in contact with Markus? I am a German student and I am looking for someone, who might be able to help me with my school project about AWE.
i think that companies would love to use the surfaces of these devices as ad plataforms, imagine, going down a highway and hundres of those whit cocacola, uber, facebook and so on wright on the larger ones kk
Markus you mind explaining what “your research” is that you are talking about? Cause it sounds like you just took other peoples research and made a presentation out of it

Very informative. Thanks :)
AWEsome presentation!

Great summary of the current state of Airborne Wind Energy and cool looking flight path optimisations! :)
Thank you for clean wind energy technologies for developing instead of fossils fuels that’s the process of carbohydrates on the atmospheric .
Thank you Markus! That's really awesome presentation and loved the idea! would like to explore more through articles and if any practical implementation ?
I'll believe it once they charge/power an electric party yacht with high-altitude kites ;)
Hii, can I get the presentation??

i found some of the info at *Airborne Wind Energy Systems: A review of the technologies*2015

i'd try here www.linkedin.com/in/markus-sommerfeld/
can i get the ppt that your r presenting
Can helium ballon sustain the weather conditions like rain as well as temperature
The Gyro wind turbine has smashed Betz limit for more detail please watch youtube video regards Graham Flowers
How can i get that videos??
Thanks !
How big would a 7Kw generator Cybertruck charger be.
Sadly, Makani is no more :(

welcome investment in Laos
Betz limit has been smashed and debunked regards Graham Flowers

No , he is the owner of this idea
go search for his name on google scholar
