Retired professor, Dr. Arnold Wilson, engineered a large, one million bushel grain storage in Alabama.

A fire burned inside for 60 days and ended in a large explosion. The dome’s top was completely destroyed. A grain explosion in a conventional silo will scatter concrete debris up to a half a mile away and will often cause fatalities. When the dome top opened, it released the explosion upward and sucked the debris back inside. No injuries, deaths, or other damage occurred.

A live load test was performed on this dome in Provo, Utah, using an incredible, 360,000 pounds of concrete block. The test showed no measurable deflection of the dome’s surface. This was Dr. Wilson’s first dome, an earth-formed, affined transformation of an ellipse, that was 160’ x 240’ x 40’ in size.

Dr. Wilson and two students examine the Crenosphere test model. A Monolithic Dome built without cables may be built to 296’ in diameter. This test showed that a cable restrained dome may achieve domes up to 1000’ in diameter.
