Historical account: inventor, Peter Olds, describes the original concept
When the inventor awoke suddenly at about 3 a.m. from a seemingly peaceful sleep on the morning of 5th December 2002, he had clear concept on his mind of how an elevator for the small foundry in Maryborough, Queensland could work. This concept was shown in the sketch he made on the kitchen table when he quietly sneaked out of bed and put his ideas roughly on paper to take to work later that morning. Quite satisfied he went back to bed without waking family and was asleep again by about 3.30 a.m.
