  1. Re:rechargeable battery? on The Internet of Things Just Found Your Lost Wallet · · Score: 1

    While some coin cells can last years in very low power applications, you'd probably do better using Gen-2 RFID tags for just finding something. The tags are powered over the air by the device reading them and do not require batteries.

  2. I've got an EV on The Quest For an EV Fast-Charge Standard · · Score: 1

    A fast-charge port was included in my car, and it has a 110V converter, but I always use the 220V converter in my garage. Very handy. The great majority of my driving is well within its range, so not having a level 3 charging stations did not stop me from getting an EV.

  3. Re:writing on the wall on Trolltech GPLs Qtopia Phone Edition · · Score: 1

    So, how difficult is cross building X11 and Gtk+?

  4. me purchasing - my purchasing on AppleTV Hits the Streets · · Score: 1

    'ing' is a noun.

  5. No evidence?? on Fermi Paradox Predicting Humankind's Future? · · Score: 1
  6. Tesla bladeless turbine on MIT's Millimeter Turbine to be Ready This Year · · Score: 1

    I've thought about using a Tesla turbine on this scale, but if there is a stack of disks, it might complicate the construction process versus this bladed design. Or is there a MEMs process which can make a stack of disks?

    The other way to use a Tesla-like design would be to use a single disk. Sort of like a design for a blood pump I've seen, though in that case it used a dome-shaped rotor.

  7. Non-public patents: Invention Secrecy Act of 1951 on Publicly-Funded Research Data is Public? · · Score: 1

    Possibly releated to this is the Invention Secrecy Act of 1951. Here's a good summary page about what happens to inventions that are considered "too sensitive" to national security: http://www.fas.org/sgp/othergov/invention/index.ht ml I wonder if most people realize this provision exists in the patent law for the government to keep information quiet, and it really makes me wonder what might be contained in the some 4800 patent applications.

  8. Insulation from distro on What Embedded Linux Distros Would You Support? · · Score: 1

    One way to look at the question of which distro to support is to ask what your SDK depends on in the host OS.

    In general, the more you insulate your build environment from the OS, the better, and the greater number of distros you will be able to support. There are several ways to do this, like chroot'ing your build tools to avoid using any host binaries, prefixing $PATH when running your tools, etc. More tricks will be needed depending on how cross-friendly all the sources you want to build are. Config-less, static Makefiles which call 'gcc' may need to be patched or told what 'gcc' means.

    Our tools run on a handful of distros and we usually run into minor issues like what /bin/sh points to (bash vs rnd shell) and missing -devel packages.

    Supporting Cygwin may go fine at first as you generate cross tools and can compile packages, but you probably will run into trouble at some point when you try to build target filesystems or release ISOs and will need certain tools which have not made it to Cygwin. People say they want MSWindows support in a checkbox kind of way, but it's not such a bad thing to require Linux for development.

    Good luck!

  9. Patent review instead of jury duty? on SCOTUS Set To Examine Combinatory Patents · · Score: 1

    How about making patent review take the place of jury duty? A group of peers could decide by vote if a patent is worth granting or keeping based on obviousness.

  10. I want CPU + heap-o-FPGAs on Nvidia Working on a CPU+GPU Combo · · Score: 1

    Are we just waiting for patents to expire to see more FPGAs in general purpose systems?

  11. yaw, pitch, roll - exif on GeoTagger Adds Positioning Info to Snapshots · · Score: 1

    Camera location (GPS) and orientation (yaw, pitch, and roll) would give you a unique position.

  12. s/nano//g on Nanocosmetics Used Since Ancient Egypt · · Score: 1

    Useless prefix?

  13. Re:Gads, this is years old on Bacterial DVD Holds 50TB · · Score: 1

    There was an article a long time ago called "The Terabit Cube", but I can't remember in which magazine it was published. Also mentioned bacteriorhodopsin, I think.

  14. Greer on Coast to Coast: SETI success on Is Distributed Computing Being Distributed Badly? · · Score: 1

    On June 1, 2006 on the Coast to Coast radio program, Steven Greer (of the Disclosure Project) stated that a "senior official of SETI" had information about successful receipt of "multiple extraterrestrial signals."

  15. Re:No turbines? on UBC Engineers Reach Mileage Of Over 3000 MPG · · Score: 1
    Good idea.

    Chrysler actually field tested a car with a turbine around 1963: http://www.turbinecar.com/ .

    Turbines have several good things going for them:
    • Simple: a single moving part
    • Clean burning from continuous combustion
    • Multi-fuel capable

    The disadvantage I usually see mentioned is that they would be expensive to produce, but I think that probably assumes the bladed variety, like those used in steam turbines for power generation. I'd like to think that Tesla bladeless turbines would work well in a hybrid electric vehicle, but that is still to be demonstrated.
  16. conspiracy of thousands? on 'UK Hackers' Condemn McKinnon? · · Score: 1
    a conspiracy this big would be WELL into the thousands
    I wonder how many people knew about the development of the hydrogen bomb? If you structure a project in certain ways, just a small number of people need to see the "big picture" while the others just see parts.
  17. Re:Acceleration Range on Electric Car Faster Than A Ferrari or Porsche · · Score: 1

    One way to recharge quickly is to exchange battery packs. You could rent a pack and exchange it for a fully charged one when you fill up. Probably a good idea to have a complete charge history stored in the pack.

  18. Re:Richard Smally V. Eric Drexler on Responsible Nanotechnology Interview · · Score: 1

    There are already cases where STMs have positioned individual atoms, and biological systems put together plants and animals molecule-by-molecule. Our abilities to manufacture and synthesize are increasing, whether it's from the top down (lithography) or bottoms-up (biochemistry).

    Take everything we know about chemistry and add a bit of positional control. This does not of course give us the ability to arbitrarily place molecules or atoms in energetically awkward positions, but should allow us to control some reactions, using suitable reactants, in a given position.

  19. Re:Foresight on Responsible Nanotechnology Interview · · Score: 1
    Yes, Foresight has been doing similar work for quite a while (founded in 1986). From Foresight's About page, it says:
    Foresight Nanotech Institutes mission is to ensure the beneficial implementation of nanotechnology.
    , and
    to educate society about the benefits and risks of nanotechnology.
    From CRN:
    The mission of CRN is to raise awareness of the issues presented by nanotechnology: the benefits and dangers, and the possibilities for responsible use.
    , so it certainly sounds like there is overlap between these two organizations.

    I've been to a Foresight technical conference, and enjoyed it.
  20. 10000 MPG on When Hybrids Do (And Don't) Make Sense · · Score: 1

    The record for mileage is over ten thousand miles per gallon.

    Look for: "MicroJoule" "Team Fancy Carol" "Shell EcoMarathon"

    These are not normal passenger cars, but we can learn someting from these experiments.

  21. Re:So why is this being called nanotech? on Nanotech Coating Prevents Fogging · · Score: 1

    One thing I do sometimes is to remove the dreaded "nano" prefix throughout the article or press release. If it still makes sense, then it's probably just chemistry or materials science.

    Is using hydrogen gas nanotech? Of course not.

    Lasers are for manufacturing, bouncing light off the moon, femtosecondizing some proteins folding, AND NOTHING ELSE.

  23. Re:500MW is not much... on World's Largest Solar Array to use Stirling Engine · · Score: 1

    Comparing the space taken by these structures versus a plant which uses fuel from some other location is not interesting. You might need to consider the large underground space needed to contain a gas field, and them I'm still not sure this comparison tells you anything.

    "Unused land" assumes that space without human-made structures has no use. Plants are making food for animals and oxygen. Food and oxygen are useful. Why not use the current dead space like parking lots, roads, and rooftops for solar?

  24. Airship + Ion engine to orbit (JP Aerospace) on It isn't Easy Being Green and Getting to LEO · · Score: 1

    I like this idea since it uses fairly simple technology. Although it would take a relatively long time to get to orbit using an ion engine(about a week), you could put cargo on airships, and people on rockets.

    Another nice thing about going slowly is that you don't have to manage all the risks of volatile fuels on the way up, and a rapid reentry on the way down.

    And when the cable is ready, do the space elevator.

  25. Water on Intel On A Building Spree · · Score: 4, Informative

    What is the estimate of how much water these plants will consume? Do the communities in which these plants are being put understand what the impact will be? Chip fabs usually consume lots of water.
