I'm shipping off to Cameroon with the Peace Corps in June. I'll be working in computer education and I've been told by those currently working in country that they are great to give out to students. So If you want to wipe them and donate them, what ever the size I would be happy to take them.

I don't know if this is correct it has been awhile since I took physics. If the gas is compressed before it hits the turbine and uncompressed as it hits it. The uncompressing of the gas cools it, and that might be enough to recondense the liquid. It probably depends on the properties of the liquid/gas they are using. Does that sound right?
