A step towards solving the worlds water crisis?

Fresh Drinking WaterAs a person who has spent most of my life living in the desert, the availability of drinking water is ever-present as a way of life. With dwindling fresh water supplies around the world, I am glad to see some progress is being made in the field of desalination.  If a few more smart people put their minds on the problem, it could be solved in no time.

“Today’s desalination plants are unlikely to solve our looming water crisis, however. That’s because they have their own unquenchable thirst- for energy. It’s needed to drive reverse osmosis (RO), the process in which salty water is forced at high pressure through a membrane that lets water molecules through but blocks the salt. But now a number of researchers and start-up companies think they have a more energy-efficient alternative, and it works by turning RO desalination on its head.” Read Full Story

Energy Is Conserved (the history) (via viXra log)

Whether you agree with him or not, this is great time-line in the history of physics.  Philip Gibbs is fast becoming one of my favorite physics bloggers. Not because of his opinions, (I have no idea who’s opinion to believe.)but because of the detail of his explanations. I guess what I am saying is, he describes physics at a level I understand. He doesn’t write in technical jargon that only physicists can understand. And, he doesn’t dumb it down for the masses like… a couple of other guys I just decided not to name. (Because I like and respect them) 

“We have been discussion the law of conservation of energy in the context of classical general relativity. So far I have not been able to convince anyone here that the maths shows that energy is conserved. Lubos Motl and Matti Pitkanen have posted some contrary arguments on their blogs to add to the old one by Sean Carroll. We have also been trading points and counterpoint in the comments with Ervin Goldfain joining in, also in disagreement with m … Read More
