The nature of their product is such that it can't be made and distributed in any centralized way...

Then why is it patentable? I wish we could go back to the way it was before, where you had to submit a physical working example of your invention when submitting a patent application. A patent on a business model should not be allowed.


Scientific American Column: 'It's Not Cold Fusion...But It's Something' ( 188

An anonymous reader writes: Scientific American magazine has published a guest column on low-energy nuclear reactions (LENR) [putting] into context the history of what was mistakenly referred to as cold fusion and what happened. The bottom line is that there is compelling cumulative evidence for nuclear reactions taking place, including shifts in the abundance of isotopes, element transmutations, and localized melting of metals. Furthermore, those reactions do not have the characteristics of either nuclear fission or nuclear fusion. Despite sharp criticism from much of the scientific community after the 1989 announcement by Fleischmann and Pons, the Department of the Navy's Space and Naval Warfare Systems Center and other reputable organizations continued the research and published many papers. The article reports that "to the surprise of many people, a new field of nuclear research has emerged," adding that even in the early 20th century, atomic scientists were already reporting "inexplicable experimental evidence of elemental transmutations."

Actually, that's not net neutrality. Net Neutrality can be summed up in 5 words: A packet is a packet. I don't know what is so hard about this. Some people will say stuff like: you have to prioritize VOIP for 911, or real time emergency alerts, or whatever. Bullshit. A packet is a packet. If you throttle or prioritize, you're not neutral. Period.

OK, Internet super-engineer. You clearly do not know anything about aircraft or spacecraft structures.

Materials used for small drones have a very difficult time scaling up to very large lightweight structures. Care to expound on the loads and stresses experienced by a 144 foot wingspan wing, that weighs only 900 lbs? This drone was built to be light and barely strong enough. That was its design point. Have you shown the world that you can do better and can credibly criticize their design?

Extremely high aspect ratio wings, like this one, just don't want to quit flying. It is a real challenge to bring it down onto the ground. The pilots possibly exceeded design Vne trying to get it down. This exponentially increases drag forces on the airframe. Ground-effect makes landing even more difficult, and with a 144 foot wingspan, ground-effect starts at ~72 feet above ground.

Add to this the non-homogeneous nature of gusting winds in proximity to the ground, and it is not inconceivable that design limits were exceeded by a fluke of nature. There is not enough public information of what weather conditions existed during landing, but sudden adverse conditions during landing are not unprecedented. Did Lockheed's engineers under-design the structure on the L-1011?

Disclaimer - I work for an aerospace prototyping firm (not related to Facebook), and have worked on things that cover the conceivable gamut of Reynolds numbers that can be "flown". Although I have not worked on Facebook's drone, I have an intimate knowledge of the modern materials used in this air vehicle. My opinions expressed here are my own.

10 to one delusion (misspelled on purpose) isn't what you seem to think it is. Take 100ml of pure water and drop 10ml of the "active" ingredient into it.
Then, take 100ml of pure water and drop 10ml of the previous solution into it. Keep repeating 8 more times. The resulting solution is just pure water.
