Combining renewable energy sources is always a good idea to increase the overall capacity factor. Checkout a recent paper of our team about a Hybrid Power Plant including also airborne wind energy doi.org/10.3390/en16104036

Yes it does. One can see this in various videos that are circulating.

agreed!

@@Laddermill this is a lost technology I believe this is probably how the pyramids was built with wind and water power… I first heard it from my thoughts… one day I’ll write a book about it honestly I never heard it or read from anyone and I wonder why! Some How I figured it out! Just now replying to this message 3:49 GMT honestly I think it’s humans in their egoistic nature too much about trying to show off and trying to compete with each other and be better than others look at me look at us etc… people forget about simple things that matters…

We used BELT elements that are available in the used MADYMO software. I have added the reference to the complete thesis, which is available in open access, to the description of the video. You will find many more interesting details in this report.

The video is without sound. But there are many videos on this channel with sound.

You can place a pre-order here: thekitepower.com/preorder/. Kitepower is a spin-off (2016) from the university research group. Their Falcon 100 kW system (60 m2 kite) is currently being tested in the Netherlands.

@@Laddermill - how much are estimated cost ?

@@grip-engineeringthumlergmb7178 The 100 kW unit costs €180k. Note that these costs are for (very) small series production, basically prototyping, not including any benefits of producing a larger series. I should also add that the 100 kW unit is not what the video depicts. The video is about the 20 kW R&D platform of TU Delft that we operated between 2010 and 2015, using a 25 m2 kite and a 20 kW generator, producing 7 kW electrical power at nominal conditions. The video shows the 2012 demonstration of fully-automatic energy harvesting at Rotterdam harbor. The spin-off company Kitepower is marketing a 100 kW solution with a 60 m2 kite and a 160 kW generator.

Thank you!

That depends on the energy storage technology that is implemented. Some systems use Lithium-ion rechargeable batteries, and some use super-capacitors to buffer the energy over a pumping cycle (alternating reel-out and reel-in phases). But one can also think of flywheel storage of mechanical energy. This video is quite old. Check out our newer videos, e.g. this one ua-cam.com/video/QiYyCb5x2HA/v-deo.html

Hi, thank you for your interest. The simulation model was developed in MD Adams, using a custom developed aerodynamic load model. More information here: J. Breukels, R. Schmehl, W.J. Ockels: "Aeroelastic Simulation of Flexible Membrane Wings based on Multibody System Dynamics". In: U. Ahrens, M. Diehl, R. Schmehl (eds.) "Airborne Wind Energy". Springer, Berlin Heidelberg, 2013. doi.org/10.1007/978-3-642-39965-7_16 J. Breukels: "An engineering methodology for kite design". PhD thesis, Delft University of Technology, 2011. repository.tudelft.nl/islandora/object/uuid:cdece38a-1f13-47cc-b277-ed64fdda7cdf/datastream/OBJ/download This toolbox will not work anymore. Note that we are currently improving this (already more than 10 year old) framework within a starting PhD project. This is a Python-based solver, combining a particle system model with a vortex step method (a lifting line type of method). First results are very promising.

See my other comment. The Kite Simulation Toolbox was developed in the frame of Jeroen Breukels dissertation. Find it here: www.kitepower.eu/publications.html It was implemented in in the multi-body solver MD Adams with a scripting layer for the aerodynamic load model. There have been a number of other tools developed since then. Very recently this one github.com/aenarete/KiteSimulators.jl

​@@Laddermill Thank you for your reply. I am familiar with Kite Simulator. The main advantage of ADAMS modelling compared with one-point and four-point masses models introduced in the kite simulator might be attitude dynamic and the more realistic steering inputs. BTW, It looks aged, and there should be a reason for this research that no one continues working on it.

This was simulated with the Kite Simulation Toolbox, written by Jeroen Breukels as part of his PhD research. This toolbox is built on top of MD Adams, a general purpose, commercial multibody solver. You will find more information here repository.tudelft.nl/islandora/object/uuid:cdece38a-1f13-47cc-b277-ed64fdda7cdf/datastream/OBJ/download

Have a look at the PhD thesis of Jeroen Breukels which you can access here repository.tudelft.nl/islandora/object/uuid:cdece38a-1f13-47cc-b277-ed64fdda7cdf/datastream/OBJ/download

We are not maintaining this toolbox anymore since > 10 years. You might want to look at other tools like github.com/aenarete/KiteSimulators.jl

bin gerade dabei einen neuen anlauf zum machen um eine dauer-genehmigung zu bekommen an der holländischen grenze bei slagharen.

You don't need a bigger kite to prove and improve the working principle. In a test phase you would only make it more expensive and dangerous. I do kitesurfing myself and despite what Wubbo is saying, 14m is bigger than most kitesurfers use in those winds (judging by the wind mills and everyone's hair). A bigger kite could not be manually kept under control anymore on the ground.

Wind.

I know it. I want to know what type of electrical machine is used in the groundstation?
