Robert Bunsen, Open Source Pioneer?
cygtoad writes "Today marks Robert Bunsen's 200th birthday. I found this interesting factoid on the man: 'Bunsen and Desaga did not apply for patent protection on their burner and it was quite soon that others began to produce their own versions. Some even went so far as to claim the invention as their own, including one person who was granted a patent on the device. Both Bunsen and Desaga were involved in writing letters to the proper authorities to refute these claims.' Does anyone have an older example of such an open information pioneer? In my book he deserves some honor." Benjamin Franklin famously chose not to patent the design of the stove that bears his name, too; you can read all about it. -
Potential 'Avatar' Gas Giant Exoplanet Discovered
Luminary Crush writes "A gas giant of approximately 1.5 Mj (Jupiter Mass) was discovered on October 22nd around the binary star system HD 176051B. It's not known with certainty which component of the binary system the planet is in orbit around at this point as both stars in HD 176051B are relatively Sol-sized (1.07 and .71 solar masses). Named 176051B b, this new exoplanet orbits within the star system's habitable zone, and if mapped onto our solar system with relative distance from our Sun it would place the large planet between Earth and Mars. While it's unlikely that such a gas giant could host life as we know it (though it's hypothesized), the location of the big planet opens up the intriguing idea of the realization of some of science fiction's famously habitable moons, Pandora and Endor. Look no further than our own solar system to see moons with the potential ingredients for life — just add heat." -
Workable Fusion Starship Proposed
Adam Korbitz writes "A former colleague of Edward Teller — father of the hydrogen bomb — has published a new paper proposing a design for what could be the first practical fusion-powered spacecraft (PDF). As described at Centauri Dreams, the design has certain similarities to MagOrion, a 1990s-era proposal for a nuclear-powered spaceship with a magnetic sail and propelled by small-yield fission devices. The proposal's author also has links to the British Interplanetary Society's Project Daedalus, a 1970s proposal for an unmanned fusion-powered interstellar probe designed to reach 12% of the speed of light on its way to Barnard's Star." -
