  1. Active stabilization? on Russia Builds World's Largest Nuclear Powered Ice-Breaker · · Score: 1

    It is nuclear power, it would seem that with 60MWe, which I presume is megawatt electricity (as opposed to thermal) one could power large gyros or at the very least have some crew quarters mounted on a Stewart platform. Water jets to provide stability?

  2. Re:This is why we need people in space on Space Station Saved By a Toothbrush? · · Score: 1

    Even better is to higbee the first thread like they do on fire hydrant and aerospace electrical connectors.

    A 38999 series connector is a good example of this.

  3. Re:This is why you buy the CD instead on Bruce Willis Considering Legal Action Against Apple Over iTunes Collection · · Score: 1

    It's hard to buy a CD with an iTunes gift card. That is a reason I've purchased music from the iTunes store. I suppose I could try selling the gift card, but it isn't that big of deal to me anyway.

  4. Re:Space WD-40? on Space Station Spacewalkers Stymied By Stubborn Bolt · · Score: 1

    It will need an ullage motor. Or a re-design with a bladder/diaphragm to keep the liquid separate from the propellant.

  5. Re:Tip for the Chefs on Ale To the Chief: White House Releases Beer Recipe · · Score: 1

    It's hard to take home a keg as a momento. I'm pretty sure the bottles will be well kept long after the beer was consumed. That is probably why it is bottled.

  6. Re:Considering... on DNA Analysis Suggests Humans Interbred With Denisovans · · Score: 1

    Interbreeding implies offspring. Otherwise it's just sex.

  7. How do they objectively measure happiness? on Scientists Find Gene That Predicts Happiness In Women · · Score: 2

    Is there some new way science is able to quantify happiness? They can measure it?

  8. Re:Next step on US Doctors Back Circumcision · · Score: 2

    Hey, we can also reduce breast cancer by cutting them off after childbearing age. Who's up for that?

  9. Re:This is a stupid idea on A Modest Proposal For Sequestration of CO2 In the Antarctic · · Score: 1

    Easy, just bury it with nuclear waste. Two birds with one stone!

  10. Re:Interesting but... on A Modest Proposal For Sequestration of CO2 In the Antarctic · · Score: 1

    In 20-30 years some group will harvest the co2 "snow" and heat it enough to change phase and feed it into a turbine to generate electricity from it. It will still go into the atmosphere, but who can predict the political and economic climate 20-30 years from now? CO2 sequestration is a battery, to be used at some future time, ideally when atmospheric CO2 levels are at a low point.

  12. Re:i hope never on Could Flying Cars Actually Be On Their Way? · · Score: 1

    I don't understand why we do not have small, one to two-person blimps flying around. The technology is there. They are safe. They might crash into eachother but will more than likely just bounce off. If they do plumet to the earth, they'll do it slow motion. We obviously have the technology. No major breakthrough required. What am I missing here?

    Safe lifting gas? He would be a waste in personal blimps. H is plentiful but the flammability is an issue.

  13. Re:Compromises on NASA Morpheus Lander Test Ends In Explosion · · Score: 2

    Absolutely! We should be using much more beryllium in spacecraft manufacture, it is a much better material than aluminum. Never mind the fact that beryllium can be toxic to a sizable portion of the population. Persons involved in its mining and processing can be exposed to it.

    It is my understanding that they want to get away from certain hypergolic fuels due to their very hazardous nature in fuel handling. The combustion products can range from pretty harmless to ammonia. I think the "green" side is on the fuel and its handling of it. The environment has people in it also, you know.

    Most engineering involves compromise, why should NASA be exempt? If it isn't weight, it's money, if it isn't money, it's availability, etc. etc. That is why reactor vessels are stainless clad carbon steel and bridges require maintenance, instead of being constructed from corrosion resistant materials throughout. Somebody made the decision to compromise, often for good reason. Engineers are only trying to work within the constraints imposed by compromise.

  14. Re:Amazing on Shatner and Wheaton Narrate Mars Rover's Landing Sequence · · Score: 1

    I'm excited about it, but I'm also not getting my hopes up. In the original "Seven minutes of Terror" they tell you the success rate of Mars missions. I'll be getting more excited once the thing lands and is functional. Otherwise I'm just keeping my fingers crossed that everyone did the job right and the mission will land successfully. Otherwise it is a lot of counting chickens before they hatch.

    If the things lands like the Genesis spacecraft, it will be very anti-climactic. (That isn't a cheap shot, I'm just saying that it isn't a sure thing).

  15. Re:Odd statement on The World's First 3D-Printed Gun · · Score: 1

    It's interesting to note that the second amendment does not apply to the mentally ill, felons, and other classes deemed unfit for militia duty.

    Probably because they don't have the resources or wherewithal to bring suit to the Supreme court. They can own archery, crossbows and other arms, just not firearms, at least in most states.

  16. Re:Making Your Own Firearms Is Fun on The World's First 3D-Printed Gun · · Score: 1

    No restriction on those who would be qualified to purchase a firearm.

  17. Re:Making Your Own Firearms Is Fun on The World's First 3D-Printed Gun · · Score: 1

    Yes indeed, at the federal level, there is no restriction on an individual constructing a firearm. Machine guns, restricted. AR15 platform, no problem. As an individual, you cannot make them for sale. You do not have to serialize you own home produced firearms.

    PC users get the cheap rate.

    Wait, Rodney King was armed during his beating? Really? Do you have some links that support this?

  20. Re:Nice on Laser Powers Lockheed Martin's Stalker Drone For 48 Hours · · Score: 2

    Ground station? Who cares, you're really pointing a bright (at some wavelength) laser beam at the aircraft. Pointing out where it is. I'm guessing this will only be used intermittently to charge batteries.

    The ground station will probably be well protected, the US tends to operate with air superiority these days.

  21. Sex is the gateway drug. on Study Finds Alcohol, Not Marijuana, Is the Biggest Gateway Drug For Teens · · Score: 1

    It can even produce new users.

    Alternating Current, that is exactly what we're talking about here.

  23. Re:How does this work? on Julian Assange Served With Extradition Notice By British Police · · Score: 1

    Yes, but he was recently in the news when he was in Switzerland (if I recall correctly). The US tried to extradite him from there, because we did have an extradition treaty with the third country. The extradition was denied, however.

  24. Re:How does this work? on Julian Assange Served With Extradition Notice By British Police · · Score: 1

    I don't think they can legally "pull him out" of the car if he is granted Ecuadorian protection (asylum). Pulling over cars of foreign embassies I believe would be a touchy issue.

    Maybe the Ecuadorian Navy could send a helicopter from a ship off the coast and get him out "Saigon style" but they'd probably have to do it on the sly because I'm sure that would violate UK airspace. Probably an expensive (politically or otherwise) way to do it.

    Romain Polanski managed to avoid extradition, and he plied an underage girl with drugs and alcohol before raping her. Of course, according to Whoopi, it wasn't "rape rape".

  25. Re:Just like RIAA and MPAA and Authors' Guild on Exxon CEO: Warming Happening, But Fears Overblown · · Score: 1

    Bad analogy. His business model is to pump out the product from long dead plants and animals and bring it to market. The RIAA and MPAA's business model is to pump out product from long dead animals and also indenture the youth who pump out product.

    Pretty close, the difference is music is still being made at a rate that can meet demand.
