- -The other evening I was watching a PBS special about the moon. I briefly
- -caught a portion of the program about some scientists creating water
- -from moon rocks brought back by one of the Apollo missions. It was being
- -done by introducing hydrogen into the rock. They showed this working...
- -you could see water dripping from the moon rock. Could someone please
- -explain this in more detail. Like I said, I only caught a glimpse of it and it
- -totally amazed me.
-
- Since the hydrogen has to be imported (water, LH2, metal hydride, plastic,
- etc.), this is basically a method of extracting oxygen from the lunar
- material (though the water would be useful too). You produce water from
- moon rock and hydrogen, elecrolyze the water, save the oxygen, then react
- the hydrogen with more moon rock to make more water, and the process
- repeats.
-
- I believe there are also oxygen extraction methods that do not require the
- use of hydrogen.
-
- Much of the research going on now is performed using *simulated* lunar
- material, made up of the appropriate mix of Earth rocks. For instance,
- EPCOT now has demonstrations with plants growing in simulated lunar soil
- and simulated Mars soil.
