Yesterday was a quiet day around the RV, trying to keep out of the heat. Sometimes you rent a movie for a rainy day, but this was the first time we rented a couple of movies on a sunny day. A HOT sunny day.
Today we left our tour of
Biosphere 2 for a hot
windy day. The tourist information office in downtown Tucson was selling Tucson Passport booklets at a cost of $15. In the passport was a 2 for 1 deal on entrance fees for the Biosphere. Since the entrance and tour was $20 each, we saved $5 by using the passport. We both felt that $40 for 2 was high for what the tour was.

You have to take the tour in order to have access to most of the facility, and the tour does not lend itself to anyone with special needs like wheelchairs or strollers. The University of Arizona is presently managing the facility under a lease agreement with the private owner. They operate the tours and of course have their own science experiments ongoing, as do visiting schools and scientists. It was opened to the public in 1990. There were two periods in the early 1990's of isolation habitation by scientists in the Biosphere - one time for a 2 year period, and another about 6 months. The interesting fact to us, was that just shortly after the 2 year period began, there was not enough oxygen to sustain the inhabitants. They had realized that the
massive amounts of concrete used for the buildings and 'rocks' inside had not fully cured and was using up some of the oxygen. A sustainable normal amount of o2 is 21%, and they were at 14% when it was decided that oxygen from the outside needed to be added. Donald and I are not scientists, but having built a house and other things, we do know that concrete takes time to cure, and in that time, it needs certain conditions and will use air. So, our little theory is that they were rushed in the initial building of the facility and rushing the 2 year Experiment, and as such, made an error. However, errors are also interesting and a learning thing.

It was good to do something different other than a desert museum or activity of the 'southwest'. There were neat new experiments that we found interesting to us, one of which was solar. There were different solar panels up and running, and by covering part of the panels, you could see how efficient they were, based on their type of manufacture. Turns out our own solar panels are fairly efficient!
So, now on the agenda is some time for a couple of personal decisions we have to make and tomorrow, we hope to meet fellow bloggers
Jim and Gayle.
They are hopefully moving back to Catalina State Park in the morning - yes there are spots here!!!!
