Maybe one can build a WITT gear swinging in the wind instead of a wind wheel. E.g. a multi winged blob with a 1 meter diameter suspended from a bridge like construction. It is hard to estimate the output. If it is about 1 Kilo Watt in gentle winds, it could be useful. A wind wheel is also rather expensive and mechanically challenging.

Yes, it could be feasable (but still expensive I agree) and WITT showed a suspended structure which could receive mechanical input from wind by appropiate wind-boards (or by attached sails): https://www.youtube.com/watch?v=8Ylzx5_h9UA 

From lancaIV's link I have found another energy harvester method, also embedded in shoes, which is able to provide at least 1 Watt nominal (10 W peak) power output. See these links:

and here with videos:

A very detailed article on the method is shown here

Briefly, the method is called reverse electrowetting combined with (nanosized) bubble growth and collapse.

Electrowetting and reverse-electrowetting are high tech concepts. I do not see a chance to experiment at home with such materials, some complicated manufacturing processes are required.

I do not see the high output, but the required materials are not disclosed. May be there is still some wishful thinking going on to attract investors.

Vortex bladeless turbines wobble to generate energy.  The Vortex bladeless turbine supposedly takes advantage of the wind's swirling motion, which generates energy from the repeating pattern of vortices, known as the Kármán vortex street, and are generated as the air separates to pass by a blunt body, such as the Vortex structure itself (see image below).  Incorporate the WITT gear into the bladeless vortex turbine, or into other similar devices.

Self Synchronization Of A System. 

A trout (vortex structure) positioning itself in a standing wave (between the vortices of air, water, etc.) ensures the trouts (vortex structure) dynamic link through the water (wind) itself.  If the standing wave shifts for some reason, the trout (vortex structure) 'mounted' on it will shift as well.  If the standing wave linking the trout (vortex structure) can't ensure synchronicity with the vortices, a driving force emerges shifting the standing wave to such speed regime in which there won't be any need to eliminate the phase displacement between the sources.  A trout (the vortex structure itself) will open it's gills and turn it's body to induce a phase displacement to break the synchronicity of the system, and the standing wave will move and drag the trout (vortex structure) upstream in its wake with a speed increase until the velocity is reached at which synchronicity of the system is possible.

The natural vibrations of the grid  (Video). 

The metronomes will sync up through it's natural vibrations and become in phase with other metronomes through the vibrations of the whole system.  However, the metronomes will not sync up with one another and will be out of phase with the other metronomes through the loss of it's natural vibrations.
