| 5 ring levels the base (r0) is a decagon of 10 struts r1 is a decagon, above r0, of 10 slightly smaller struts. r2 is a pentagon above r1, of 5 struts r-1 is a decagon, below r0, of 10 slightly smaller struts. r-2 is a pentagon below r-1 of 5 struts | |
| a 2v geodesic dome a 2v geodesic dome is constructed of 2 sizes of struts, such as 3/4 inch diameter steel emt of effective 38 and 36 inch lengths. they can be cut from pipes ten feet in length, the ends pounded flat and holes drilled 38 or 36" apart there are 65 total struts. in addition to the 25 in r0, r1 and r2, 20 rising from r0 to r1, 15 from r1 to r2 and five from r2 to the top | |
| 10 foot support rod r0 is bisected by a 10 foot support rod, such as 1 inch diameter iron pipe and has ten connection points, all the same height r1 is jagged, it has five higher connection points and five lower ones. r2 has five connection points, all the same height all of the connection points have handles | |
| Water flow Rain water drains into the pit and the mud it forms is extracted Scary The dome looks dangerous, but is safe. It can scare those not in the know | |
| Tools and preparations Shovels, Picks, Rakes, and Wrenches. Also power tillers, hoses and nozzles. Dig a foot deep of dirt out of the dome, this will be hundreds and hundreds of shovelfuls. Rake it away. Climb on the dome, shake it and rotate it. Dig a second foot of dirt out of the dome. Remove a strut to make entry easy | |
| location owls.assist.strut Every 3 square meters of land on the planet is identified by a unique combination of three words. Dome 0 is at owls.assist.strut More land is needed to spread the earth removed from this area. 82 ft x 82 ft, or 5/32 of an acre is plenty. Think of this as only a small amount 77 million owners hold the 1.3 billion acres of private US land, about 17 acres each | |
| Materials and excavation Steel struts with holes on the ends, 35 long (36'') and 30 short (32'') made from 1 inch or 3/4 inch diameter pipe, washers, nuts and bolts. Wait till the rain, flood, tropical storm or hurricane, then tread a path around it. Drive a stake deep into the earth in one of the base decagon corners, rotate it again and again deepening the pit | |
