Are you a "Dune
" fan? If you don't know, "Dune" is one of the most widely read science fiction books ever -- there are actual a bunch on Dune books now, both by Frank Herbert, and his son. The book is largely set on a completely arrid planet where the residents wear "stillsuits." Stillsuits are clothing that allows for the recycling of all bodily fluids.
Would you believe that NASA has been working on precisely such a device
? The best part is there are some people trying to leverage that NASA-developed technology for humanitarian work. That's cool!
