    Hmmm... Must have missed that Alex Chiu stuff, I just read through those Q&A, a few points:
    1: He seems to be selling snake oil, he better figure out a way to base theories on real science or at least base them on psuedoscience that itself attempts to base itself on real science.
    2: He WANTS China to reclaim Taiwan??!!?!
    3: He was asked about human rights violations in regard to Tibet and ignored that half of the question and spouted on about population control.

    Conclusion: Braindead crazy commie who is tricking good capitalists out of their money so that he can lead his immortal army to invade Taiwan, therby insuring that we can't get any more good deals on tech toys from there (if we can at all). This = Evil. Bad monkey, bad monkey.

  7. Faraday shielding on New Lighting Technology To Wipe Out Wi-Fi Access? · · Score: 1

    I have been a bit concerned with the issue of rf 'polution' in this area
    of spectrum for a while now. I am no expert on the subject, merely an
    undergraduate BoC student, but the only solution that I can think of is legislation
    that requires homes to be built (including extensions on existing structures) with
    some level of faraday shielding. The problems with this are that there are relatively
    few people who are actually affected by this and forcing the many to incur costs to
    'support' a minority doesn't go down well with most people. And then you have
    the law-enforcement issue, such shielding will prevent or diminsh the reception of
    TEMPEST radiation and become an obstruction to the course of justice.
    As the effect on humans by EMR in regards to carcinogenic factors has not
    resolved a conclusive answer, the argument cannot be put forth that such shielding
    will reduce the likelyhood of cancer, this in itself would be enough for most people
    to willingly install such shielding.
    From an environmental issue though, the increased efficiency of RF lighting is
    great, but the reduction in the generation of greenhouse gasses is offset by the
    generation of RF pollution, as my grandfather would have said, "...wish in one
    hand, and shit in the other." The carcinogenic properties of EMR need to be
    investigated further in order to make people listen and think about these issues a
    bit.

  8. Time travel paradoxes on Impossible Movie Stunts? · · Score: 1

    parodoxes? parodoxi?
    Anyway, I put this here to limit redundant posts.
    Time paradoxes do not exist if you consider the parrallel universe theory. Any warping of spacetime that leads to traveling back in time instead places you back into another 'mirror' universe. Therefore if you squish your grandparents, it doesn't matter because you have come from another dimension. And as there is a different universe for each outcome of a particular quantum event, there are a lot of places to visit.

    Which brings to mind Sliders, there is no guarantee that he every gets back to his real home, claiming to measure a specific signature of each possible universe doesn't quite cut it because the device he uses to measure that signature would need a phenominally high resolution for starters and the storage requirements to remember where he has come from would also be great. There does exist the possibility that he does get home, but it isn't probable and there is no way of being 100% certain.

  13. Re:Let me be the first.. on Spark Gaps and Ultra Wide Band Data Transmission · · Score: 2, Interesting

    Jesus fscking Christ, some people just need to be shot in the head. Tesla WAS a genius, the fact was that he got screwed over too many times. If he had more business sense, his accumulated wealth would make Gates look poor. Westinghouse had a deal going with him for $1 per hp generated by his electric motors, westinghouse started to go poor so Tesla ripped up the contract.
    Tesla wanted to transmit power and allow people free use of it but his financer (J.P.Morgan) realised that he wouldn't be able to make a profit off of it so he canned the funding (part of the reason was that Tesla had previously told him that he wanted the money to build a global communications network but was building a facility to transmit power instead).

    Every day your life is affected in some way by Tesla-tech. AC in all its forms for starters and then even the ignition coil in your car is Tesla-tech, as is the flyback transformer in your TV/CRT.

    Then there was his research on 'scalar' waves, these were standing EM waves. I thought this was fantasy, but I did some calculations the other night and they work:
    Start with four sine waves of different frequency, a,b,c and d
    Multiply a and b and c and d
    Then add the two resultant waves:
    (a * b) + (c * d)
    Now plot them, but have the four waves changeing as if you are watching a window of the transmission, have a few cycle of each on screen and change phi so they move.
    The moving vector waves, when computed together to form the scalar wave will have an interesting effect. A scalar wave will be created that has nodal points in free space and have a varying amplitude. It is a bit ricky to explain without images but you have enough info to do that yourself.
    Some of the claims regarding scalar waves have yet to be proven to me, I still have some experimentation to do (I do B of C, no CS at this uni. campus so all in free time) to justify these facts to myself, but it is claimed that scalar waves can propagate FTL and it is possible to modulate the speed. Also when two scalar waves are combined, they recreate a vector wave, I proved this to myself last night. The theory goes that if you can send out two scalar wave at different speeds and with a suitable time separation, you can cause them to re-create a vector wave at a certain point and somehow be able to receive that vector wave at full power (fan-fscking-tastic for wireless networking). This can also be used to generate EMPs at a distance, create force-fields (Tesla shield) or create fantastic explosions (Tesla's death ray). Tesla claimed to have caused the Tunguska explosion with early experimentation on this.
    For more info on scalars do a Google on Tom Bearden.

    The chamber is known as a vortex tube the German name is the WhirbelRohr.

    Basically, you have a cylinder with both ends sealed off, on each end you attach a narrow length of pipe, one tube has a large hole goin through into the cylinder, the other has a smaller hole, slightly smaller. Both of these holes are axially placed. Now you add another tube to the side of cylinder, but placed so that it enters at a tangent, this also has a hole into the cylinder.
    Now force air into the tube on the side, as the air is injected tangentally to the cylinder, the air will swirl around around it eventually gets to the center. Pressure variations inside the cylinder will seperate the air into hot and cold, hot will come out of one pipe and cold the other.
    This device will also produce a strange noise, any attempt to cancel this noise will stop the device from functioning.

    Further details can be found Here
    I have been considering using this in a cooling mod but as my parents complain enough about the current noise, I don't think I'll push my luck any further. Besides, steps need to be taken to handle condensation on the cold tube.

    Building the device to ideal measurements will get you some very cold air:

  16. Faraday Cages on War Driving Version 2.0 · · Score: 1

    The solution is simple, an EM hardened house.
    By building wire mesh into all the walls and turning the house into a Faraday cage, most of the radiated signal can be blocked and also make the house more impervious to EM disturbance.

    If you were really paranoid you can also do the windows, but if you still want light to get in, all you could do is use real fly-wire (not the cheap plastic crap) and figure out some way to ground it, probably by just grounding the frame.

    The only disadvantage is if you want to go outside and use you cordless phone while gardening or some such. But otherwise, it lessens the chances of somebody snooping you X10, cordless phone and even TEMPEST (totally obliterates the risk if you go hardcore).
    It also has the advantage of cleaning up the airwaves outside for 802.11 comms. It would make everybody happy, except for those trying to gather TEMPEST data, but there are other alternatives for them anyway.

    Ok, everything is ready. All I need now is a way to tie it all together. That is where
    a device called the i-Pac came in. This is a very well designed device that allows me to hook up arcade joysticks and buttons, and program them to work as regular keypresses. It connects to the standard keyboard port, and allows me to connect a keyboard as it has a passthrough port, but a keyboard isn't needed once it is programmed. Programming the thing is a very easy process with the programming
    software included with the device. The device itself is printed with wiring instructions,
    and connecting it all together is VERY simple. Don't be intimidated by the wiring. You don't even have to do any soldering! Just crimp on some connectors to slip onto the joystick/buttons, and at the other end, they just screw right into the i-Pac using a screwdown type wiring block. It really couldn't be much easier. And since I don't need a mouse, this solution works perfectly. If I did, however, need a mouse, I could use an arcade trackball and an optipacdevice from the same company. Step nine done!


    He thinks he doesn't need a mouse, I would disagree, but thats just me. I guess the idea is that joysticks are more intuitive to arcaders than meece are.
