MikeChino writes "Scientists at the University of Wisconsin-Madison have discovered that a mix of zinc oxide crystals, water, and noise pollution can efficiently produce hydrogen without the need for a dirty catalyst like oil. To generate the clean hydrogen, researchers produced a new type of zinc oxide crystals that absorb vibrations when placed in water. The vibrations cause the crystals to develop areas with strong positive and negative charges — a reaction that rips the surrounding water molecules and releases hydrogen and oxygen. The mechanism, dubbed the piezoelectrochemical effect, converts 18% of energy from vibrations into hydrogen gas (compared to 10% from conventional piezoelectric materials), and since any vibration can produce the effect, the system could one day be used to generate power from anything that produces noise — cars whizzing by on the highway, crashing waves in the ocean, or planes landing at an airport."

This follows-on from their original announcement on CC0. The CC0 waiver system is a major step forward for the Creative Commons Organization in terms of their public domain efforts. Even though it isn't a true public domain dedication, it only waives the rights as far as they can be waived (Note: Moral rights, in many countries, can not be outright waived), it opens up what is likely as close to a public domain option as practical under the current legal climate."

Linux.com (which shares a corporate overlord with Slashdot) has an interesting look at what going proprietary can mean for your overall effectiveness. Using Firefox extension "Interclue" as the object lesson, the piece looks at both the engineering and social difficulties surrounding the project. "Even more significantly, the efforts to commercialize only detract from the software itself. The basic idea behind Interclue would make for a handy Web utility, but seems too slight to build a business around. The effort to do so only leads to complications that do nothing to enhance the basic utility, and to pleas for donations that can only annoy. The result is that, if your position on free software doesn't lead you to avoid Interclue, the efforts to monetize it almost certainly will."
