Eden Project Biomes by TaffGoch
Eden Project Biomes
Geodesic dome dimensions, regarding full theoretical spheres. (In other words, the depiction does not show the dome truncations, employed to fit the hilly terrain)

"Subdivision" refers to Class-I icosahedral "frequency." (Edge of icosahedron subdivided into 9 or 15 segments)

Data obtained from an Eden Project structural-engineering report. (This depiction emulates a diagram from the report)

"The Structural Making of the Eden Domes"…
 - or -…

For this depiction, the "pillow" domes were 3D-modeled in SketchUp
Gears; Enneacontahedron

Gear axes are centered on vertices of a rhombic-enneacontahedron (as shown in animation)

32 large gears - 30 teeth each
60 small gears - 16 teeth each
Note:  Paul Nylander derived this arrangement, as well:…
Geodesic Sphere Gears
Gears; 15-21-16 by TaffGoch
Gears; 15-21-16
This arrangement provides (virtually) equal spacing between adjacent red gears. Also, compared to other, previously-posted, arrangements, these three gear components have lower tooth counts (and, therefore, larger teeth.)

I am, currently, checking adjacent tooth fitment, to assess potential for "rattle"...
Clockwork - Steampunk Sphere by TaffGoch
Clockwork - Steampunk Sphere
24, 20 and 16-tooth gears; 92 total

Icosahedral, dodecahedral and buckyball geometry

3D-modeled in SketchUp, rendered in Kerkythea

If you can't tell, already, I'm enamored of geodesic constructs.

It is my hope that these deviations will inspire others.


If you ever need help with the geometry of geodesic domes (or spheres,) there is help available:

Found Domerama online. Blew me away! Never thought such a comprehensive resource existed. Makes me wonder why I'd never seen it before.. hum. I'll be checking in from time to time, you got some great work up here. :) Cheers!

Funny thing: Most of my work doesn't show up in Google searches. (I have no idea why.) Generally, people find me & my geodesic constructs through links at other websites (like Domerama.)

I hope you find things, not only visually appealing, but technically helpful, as well.

A forty-year obsession, I'm afraid to admit....

Hi :)
Your gallary is just like my ideas now. I'm making sime calcs with spheres and some time I'll ask for help. Happy to find you :)

Feel free to ask. I don't know that I can help much with calculations. Except for the phyllotaxis deviations, I didn't use calculations -- I employ geometric construction methods.

Hopefully, however, I should be able to point you in the right direction.
