As a resident of Sydney, I may be qualified to answer some of Faioli's questions.

There's not just one torch that needs to be refuelled - each Olympic Torch Bearer gets their own torch, which they can purchase for $200...and probably sell on eBay for $1000. The exception was the final 5 runners who passed the torch around Stadium Australia during the Olympic Opening Ceremony - they passed the same torch to one another.

The torches themselves hold enough propane to burn for at least an hour, contained in a replacable canister. During the Torch Relay, one schoolgirl was burnt moderately when the torch seemed to explode in her hand. An old man had a heart attack and died during his run...perhaps from the exertion of the running. There was even a special torch that burns under water, and was taken below the sea at the Great Barrier Reef of the Queensland coast.

The torch was carried by about 10,000 people, and was carried large distances by planes, trains and automobiles, between towns. It was also carried by Surf Rescue Boat, Ferry, Sydney Harbour Jetcat, and had a ride on the Scenic Railway at Katoomba. During flight, the actual flame itself was transported in a small lantern. A few times, the torch went out, so they lit it again off the lantern.
