  2. Re:Corrosion is inevitable. on Recovering Moldy Electronics? · · Score: 1, Insightful

    It depends on the degree of corrosion. Since corrosion cannot be repaired, there is only a prayer. Make sure your electronics is completely dried out, then power it up outside your house on Halloween night. Kids will appreciate the sparks and smoke.

    As for disinfecting it: mold is heat sensitive - it likes cold wet dark environments best (in sealed cask, furry adipocere!) - so having your electronics running outdoor for a day or two should take care of disinfecting the inards. You wash the case from outside with household disinfectant cleaners like Lysol but I advise against spraying any liquid on the circuits, especially not stuff like bleach (eats metals) or rubbing alcohol (eats resin wire insulation). If it makes you feel better, you can also try blowing hot air into it from a hair gun, or tumble it in a laundry dryer, or hang it up in a cold hardwood smoke for ten days.

    He was far from the Nevada dry lakes where he said he would be flying. He had absolutely no use to fly over High Sierras, in Minarets area, in direction towards Yosemitees, especially in time of a thunderstorm and bad visibility. The only good guess is that he veered off while incapacitated so there was no distress call. The aircraft must have plunged into mountainside at cruising speed - the wreckage is scattered over a wide area.

    I think the satelite image available on Google earth dates from 2005. (But even if it was recent, is is hard to spot a small plane wreckage when if it plowed into steep mountainside in High Sierras - many places have snow cover even in late summer.)

    The crash site its near Minaret Lake in Amsel Adams Wilderness (as mentioned in SF Chronicle and Wired). The hiker who found the site went far, far north-west from his home in Mammoth Lakes - way up in High Sierras. Its is a gorgeous place, and very remote.

    I suppose the investigators are not too keen on having clueless media dudes descending on the area so they have been coy about the actual location, describing it as "near Mammoth lakes"

    There are laws protecting people from hate speach - and these laws got used against a French author who dared to proclaim in public interview, when asked about Bible and Koran, that Koran is a lousy piece of literature and revulsive for him to read (he got aquitted in court only because Muhahamad is a historic person and he was criticising the literary style not the religion, etc.)

    Our military has a long tradition of funding crackpots and loonies that do secret work on blood-curdling woodoo, see "The men who stare at goats" from Jon Ronson and "Imaginary Weapons" from Sharon Weinberger. Even the Scientology Church could learn new "spiritual tech" from our military experts.

    The idea of activating fear circuits by chemicals sounds like a pure moonshine - but there is no need for it because the military has already the equipment to project a loud shrill interference-laden high-pitch sound that makes one to run and feel like loading the pants at the same time (directionally projected over a half-mile distance). There are radar-like dishes to send microwave frequencies causing intense burning skin sensation through clothes. There are super-potent bad-trip producing hallucinogens and odors that make one puke his guts out.

  16. Nothing extraordinary on Snortable Drug 'Replaces' Sleep For Monkeys In Trials · · Score: 1

    For years there has been a very cheap and safe drug that does just that - Modafinil. It is a pill, it does not have to be snorted.

    You can stay awake on modafinil for up to 3 days in row without sleep - it is not pleasant since you dont feel refreshed but you are also not exhausted. Modafinil is devoid of the manically stimulated, clenching-jaw, no-one-can-stop-me-now driven delusional state like with amphetamines. Modafinil has no pleasure-producing qualities and no long-term ill effect. But rats kept on modafinil for over a week without sleep suddenly developed immune system failure and internal infection. It is known independently that lack of sleep makes one more prone to infection so it seems sleep is needed for proper functioning of immune defense.

  23. Re:clean nukes are just old propaganda on Nukes Against Earth-Impacting Asteroids · · Score: 4, Informative

    It is not true at all that "most modern weapons are much cleaner than the bombes of the 50s. In fact the fusion yield of modern weapons accounts for less than 40% of the total yield, most of the yield actually comes from fission of the uranium container that doubles as a reflector. "clean weapons" can be produced by using non-fissionable reflector like lead, this causes at leat 40% increase in total weight of the weapon design while reducing the total yield approximately to one half. The example of a super-clean bomb is Tsar Bomba that exploded at about 52MT, a lead-reflected test of a 100MT design.

    For military the intense radiation from fission of the uranium reflector is an "added bonus". The premium in thermonuclear warhead design is on light weight and narrow diameter (long narrow-cone re-entry vehicles have much better precision than fat ones) in compromise with low cost (low consumption of expensive materials like tritium and plutonium) and high reliability.

    The clean weapon was a temporary fad in 50s and early 60s, it was used by rival weapon design team to justify existence of Lawrence Livermore Laboratory and was oversold, being seized upon by politicians it got disproportionate coverage in print - but it never resulted in a weaponised design. The reality is that even a "clean" bomb designs are still an order of magnitude dirtier than Hiroshima and don't offer any military advantage so they are not stockpiled. The peaceful uses of clean nukes like digging harbors and re-livening natural gas and oil fields never materialized as it turned out that produced crater (or gas) was unpleasantly radioactive (because of neutron-induced radiation, with long-lived radioisotopes like C-14 and tritium)

  24. Re:nukes overhead on Nukes Against Earth-Impacting Asteroids · · Score: 3, Interesting

    Nuke explosion high in the orbit was tested as a radiation shield in antibalistic missile experiments (Operation Argus, by Nick Christofilos of Lawrence Livermore fame) and it was found ineffective for the defense purpose. A side-product of these experiments with artificial radiation shields was discovery of Van Allen radiation belts.

    It was later found by accident that multimegatonn explosion high in the orbit can dump lots of charged particles (mostly high-energy electrons) into Van Allen belts where they persist for many weeks during which time they gradually degrade solar panels and electronics of satelites - this happened in 60s (after operation Starfish Prime about 5 satelites went silent...)

  25. tank failure? on Explosion at Scaled Composites Kills 2, Injures 4 · · Score: 1

    I guess the big nitrous tank has ruptured, the fire was a secondary and happened after the tank failure. Stuff burns in nitrous oxide quite nicely, like in oxygen. I don't believe nitrous oxide has explosive properties (unless it is mixed with some flammable material). This would be consistent with the shrapnel injuries and burns of the victims. Also, if any explosive substance in a hundred kilo quantity had truly detonated, there would be nothing left of the trailer, there would be only a hole in the ground.

    Nitrous oxide tank has to be able to handle pressures about as high as tanks for acetylene welding gas (much higher than in the common household propane tanks). Building the Space Two nitrous tank must be quite a challenge - I think they are using composite materials to keep it reasonably light. During compression and release, there are high temperature fluctuation inside the tank (like in the fridge freon compressor) and it is possible that cold/heat shocked composite wall of the tank cracked under the pressure.
