Tangential (266113) writes "Looks like Money Rules everywhere. From the Bloomberg article "How Foreign Students Hurt U.S. Innovation", "International students are attractive to strapped colleges because they tend to pay full tuition or, in the case of public institutions, pay more than full price in out-of-state rates. Last year, this was taken to a new level at California State University, East Bay, a public institution just south of Oakland. The school directed its master’s degree programs to admit only non-California students, including foreign students." Or is this a comment on Californias secondary education system?"

Tangential (266113) writes "New study is out which finds that the inefficiencies associated with wind power actually raise emissions. From the study: "the frequent ramping up and ramping down of other power sources to compensate for wind’s unpredictable variability causes such inefficiency in power generation that overall carbon dioxide emissions rise. The effect is similar to that of automobile gas mileage. A driver who sustains a consistent speed of 60 miles per hour will get better gas mileage than one who frequently accelerates and decelerates between 45 and 75 mph. The inefficiency caused by frequently ramping up and ramping down vehicle speed is substantial enough that the vehicle driven at variable speeds will burn up more gasoline than one with a lower fuel economy rating driven at a consistent speed.""

It's a kitchen degreaser. It's a window cleaner. It kills athlete's foot. Oh, and you can drink it.
Sounds like the old "Saturday Night Live" gag for Shimmer, the faux floor polish plugged by Gilda Radner. But the elixir is real. It has been approved by U.S regulators. And it's starting to replace the toxic chemicals Americans use at home and on the job.
The stuff is a simple mixture of table salt and tap water whose ions have been scrambled with an electric current. Researchers have dubbed it electrolyzed water — hardly as catchy as Mr. Clean. But at the Sheraton Delfina in Santa Monica, some hotel workers are calling it el liquido milagroso — the miracle liquid." top
Tangential (266113) writes "An article on Adamant by Russell Seitz discusses the incredibly high cost of Hydrogen.
From the article:
H is for Hydrogen — the cleanest fuel there is . As long as it is made out of water. Which it is — right ?
Dream on- hydrogen produced from H2O is a rare and precious commodity , costing a quarter its weight in silver because of the high price of American electrical power — most of which comes from coal. But don't count on cashing in the contents of your bathtub just yet . Though the hydrogen in a pound of water is worth $22 on paper, pure hydrogen produced by water electrolysis can't compete with the ordinary stuff, made from natural gas — it sells for $6.00 a kilo liquefied . The two processes costs don't cross until electrical power gets _almost _ too cheap to meter — under thee tenths of a cent per kilowatt hour." top
Tangential (266113) writes "I've got several vacation rental homes which I both use and rent out. I want to equip each one with a cable modem and a wifi router so that my guests (and I) can have internet access. It would be free to my guests, but I don't want to just open it up to everyone in the neighborhood.
I don't really want to provide tech support to my guests, so I don't want to use WEP or WPA. I'd prefer to have a login screen (like hotels do) and a password (that I could remotely administer.) That would simplify connections and allow me to include a TOS (terms of service) screen.
So far, in researching this, it looks like EWRT might be what I want, but I am not sure if that is the correct choice. I want the solution to be self-contained (ir: in the router) and not require access to a remote authentication server. I also don't want to spend an arm and a leg, since I'll also be paying for the cable modems at each house and some sort of dynamic dns so I can remotely access them.
