Kite Power No Tower

Thanks again! to Local Legend Captain Angus Smith, who helped test this ring to ring rig.

This rig is different to before. Where there used to be a “rope torque ladder” at the bottom of spinning kites. Now I have a ring to ring torque transmission system. It ran so well. I’ve probably set the ring gap a bit short. It looked like it could take a lot more torque even in lift lulls.

Some big pictures.

This one is working despite the central line snap due to rubbing... A bit of Bushing will sort that.

Please read this Windswept and Interesting report into Airborne Wind Energy.

NEW: The report has been updated to this new version

It highlights a new approach, using evolutionary design software to design kite networks.

Kite networks are proving themselves.

Please join the effort to bring an open hardware energy solution. The more people who join, the faster the system evolves. The document is on version 4.3 now. Because of help and advice from Ben Lerner, Graham Brightwell and many others versions 4.4 and 5.0 will be out soon.

High altitude airborne wind energy isn’t yet common, nor is it easy to analyse. Thus it has been hard for organisations to commit to funding research. There is a new push for airborne wind energy research. Hopefully the results of this AWE scoring matrix can help to clarify the potential of problems and opportunities inherent in various approaches.

More tests showing that top nets connecting multiple tethered kites make for a more stable meta kite lift system.

Electricity definitely goes into the battery. But keeping the toque along the drop from the kites relation to the gen set torque was never going to be simple. A software solution in the motor plus some ring to ring transmission as the ladder will prove helpful.
Daisy Kite Spinning a generator, Airborne wind energy, flying wind power

It’s been too long since the last post sorry.
NEWS: I’ve been testing the newest Daisy model. Looks like it will spin a lot faster. Bit too easy to collapse though, so stiffening the lead ring should improve it.
When She spun, Daisy broke the crank connection on my bike / generator. It was misaligned so I’m changing to a front forks gimbal bracket design.

I’ve been to NZ to see Peter Lynn since I last wrote. He let me build his latest Single Skin Single Line lift kite. WOW Has it got power! I used it for the test which broke the crank.

The torque ladder transmission system is working well. I have added rings to cap the ends of the ladder. The rings have conical attachment lines to the tension line. This greatly improves alignment.

Photos and details of recent development are available on evernote open kite design notebook cc4.0

Enjoy the site for now. More soon.
