1. Geo (earth) Desic (divided)
The Geodesic Dome
Geo (earth)
Desic (divided)

2. Geodesic Domes are energy and material efficient

3. Geodesic Domes can span large interior areas
Notice that there are NO interior support columns

4. Discovered by Buckminster Fuller
‘Bucky’ Fuller in front of Casa Manana Theater in Fort Worth Texas

5. Complicated Math?
The geodesic dome ratio took two years to calculate without a computer.

6. Simple Directions!
Find an existing Geodesic ratio and create triangles.

7. Use any material
Warning! Food will melt!

8. Which ratio do I use? To build a 2V Dome with a radius of 30cm
Radius = 30 cm
                                                                                          
Which ratio do I use?
To build a 2V Dome with a radius of 30cm
35 Struts cm each
30 Struts 16.4 cm each
To build a 3V 5/8 Dome with a radius of 30 cm
30 Struts cm each
55 Struts cm each
80 Struts cm each
To build a 4V Dome with a radius of 30 cm requires:
30 Struts 7.6 cm each
30 Struts 8.86 cm each
60 Struts 8.84 cm each
70 Struts 9.39 cm each
30 Struts 9.75 cm each
30 Struts 8.96 cm each

9. Kit homes are not a new Idea

10. ‘Square’ houses have natural fatal flaws

11. Domes can range from very small…

12. To very big

13. The dome at Epcot has been through MANY storms.

14. More triangles mean more strength and stability
These two designs are filed with the United States Patent office.

15. Geodesics are more common than you might think.
South pole research station
Pop-up tent
Dopplar weather radar
Football
(yes, this is called a football)

16. Your Turn! Research, design and build a Geodesic Dome.
You may use any dimensions and any type of material for construction.
You must turn in the dome and a data sheet showing which dome ratio you used along with all math steps.
Also show the predicted and the actual dimensions of your dome.
