MIT accidentally discovered a cleaner smelting process
Sometimes, science can take an unexpected turn. While trying to develop a new kind of high temperature storage battery, MIT researchers accidentally stumbled upon a new, more efficient process for smelting metal -- one that's potentially cheaper, safer and less harmful to the environment than traditional ore processing.
Stanford researchers find a cheaper, better way to make hydrogen gas
A team of researchers from Stanford University unveiled an easier and more efficient way to strip hydrogen atoms from water molecules on Thursday. It's still the same electrolysis method that's been in use for years. But instead of using two different kinds of material for the cathode and anode, like conventional electrolysis procedures, Stanford is incorporating a pair of identical nickel-iron oxide catalysts. When a 1.5V current is applied, the system operates at 82 percent efficiency -- many times more than what its conventional equivalent can make with the same charge. It could be precisely the production breakthrough that the hydrogen fuel economy needs to actually take off.
Fennec (a.k.a. Firefox Mobile) goes alpha for Android and Nokia N900
Well, it looks like you can finally get rid of that less-than-stable pre-alpha release of Fennec (a.k.a. Firefox Mobile) for Android -- Mozillla has just released the full alpha release for not only Android (2.0 and later), but the Nokia N900 as well. The big news with this release is an increase in "performance and responsiveness to user actions" (always a good thing), as well as two new features dubbed "Electrolysis" and "Layers," the former of which lets the browser interface run in a separate process from the one rendering web content, while the latter promises to "greatly improve performance in graphic intensive actions like scrolling, zooming, animations and video." You'll also get full support for add-ons, and Firefox Sync built into the browser to let you have a continuous experience as you move between devices. Hit up the link below for the download link, and for a quick video overview of what's in store.
Korean tech makes hydrogen up to 30 times cheaper to produce -- clean energy solved?
With oil prices in free-fall and the world's economies in the toilet, short-sighted governments and C02-denying GM execs will undoubtedly defer priority given to clean energies in the next round of fiscal budgets. Too bad, because Korea's S&P Energy Research Institute has just issued a press release about a new discovery it claims puts the era of clean energy within reach. Dr. Sen Kim claims to have achieved the separation of Hydrogen using just 0.1kwh of energy compared to the traditional 4 - 4.5kwh required using the ol' electrolytic method. Dr. Kim postulates that "manufacturing the H2 by our method will lower the cost of H2 as much as 20 - 30 times" compared to electrolytic H2. That makes SPERI's method suitable for H2 fuel production from say, an in-home hydrogen fueling station. So is this the solution to all of our clean energy concerns? Perhaps, but we've heard these economical hydrogen-generation claims before. Let's wait for the claim to be more thoroughly vetted by bigger brains than our own before getting too hopeful.
