098 – Kitepower: Airborne Wind Energy
| Rate/Vote |   (average: 4.61) Loading... |
This episode is a conversation about airborne wind energy. In particular, we talk to Roland Schmehl who leads a team of researchers and engineers at TU Delft who develop the Kitepower system. In this system, kites are automatically flown in a pumping pattern to extract energy from wind as an alternative to classical ground-based wind turbines. In the conversation we cover the benefits of airborne wind energy in general and of kites in particular and we cover in some detail how the Delft system works technically.

Great episode, renewable energy always excites me. I find myself viewing systems and imagining how much energy can be reclaimed from them. Regardless, I would have liked to hear what might happen if an average plane at an average speed and elevation hit a considerable amount of these cables. Would they even be visible to a pilot?
If you hit these cables, I am sure it will be a problem. Consider that they can hold more than a ton. If a sports plane or a glider would hit one of those, it would at the very least slow down the plane considerably, which, if you are slow enough, will make you fall out of the sky. Whether you can see them? Depends on the lighting conditions, I guess, but I suspect you wouldn’t. It is hard to see ropeway cables, and those are much thicker! You’d have to have significant restricted airspace around them.

Look the video kite power by http://www.xs4green.com
Good interview. Relaxed and clear discussion of all the details. Interesting to hear about the long-standing height record. The chain of kites makes good sense. With a few smarts in coordinating the various wings and a bit more durability of the materials in UV it will be a sensible way of generating renewable energy. I liked the approach to the complexity of modelling.
I am really a bit sceptical wrt. to having groups of such kites “flying” around all over the place. As a glider pilot, that is going to be a serious impediment to my ability to fly in those areas. And you need big areas to make the kite thing work in a meaningful way!
Very interesting episode. I had never even heard of kite power for energy production.
One of the pleasures of doing omega tau is to learn about all these things :-)

Are there any regulations regarding glider flight?
What do you mean? In general, of course, there are many regulations regarding glider flying :-)

Good interview. Relaxed ALONG WITH clear discussion regarding the many details. Interesting for you to hear Concerning the long-standing height record. the chain connected with kites makes good sense. which has a few smarts in coordinating the many wings IN ADDITION TO a good bit further durability of a materials with UV That will be a sensible technique of creating renewable energy. we liked your own approach towards the complexity associated with modelling
