So, say you're an Icelandic tour company, with access to an extinct volcano (or, at least, a volcano that hasn't erupted in 4,000 years). And say you want to offer tours inside of said volcano, to tourists who don't have the rappelling experience to get themselves down and up the steep sides of the volcano's crater. How do you do it?
We use a system normally used to carry window cleaners outside of skyscrapers, an open elevator system. A basket that holds 5-6 persons is connected to a crane that has been placed vertically over the crater opening. Massive cable wires move the basket up and down the bottle-shaped vault. The 120 m/400 ft journey takes about 10 minutes to complete.
I really dig this solution!
