--04 June 2014 UPDATE:
Want to make your own turbine add-on? Now you can! I have written an instructable
describing the design and modelling process for this turbine kit.
(I tried entering the instructable into the Gadget Hacking and Accessories Contest
by Instructables.com / Shapeways / Popular Mechanics, but the entry was rejected... I guess they didn't see the Strandbeest as a gadget...oh well) --
A turbine kit designed to work with Theo Jansen's AG5 and AG7 strandbeests, available here at shapeways:
Animaris Geneticus Parvus #5
. (Animaris Geneticus Parvus #7 is extinct unfortunately...)
Functionally similar to the official Propeller Propulsion
, this addon positions the propeller/turbine on top, centrally over the strandbeest.
The addon moving parts are fitted in the gap in the middle of the strandbeest and use sections of the frame as axle and drive shaft, reducing the number of additional components
I'm quite happy about this design and the elegant way it keys into the AG5 & AG7 :)
