    You didn't quite balance the equation okay either, it's 2H2 + O2 --> 2H2O. 8-)

    Also, you are still using a combustion, which has efficiencies limited by a thermodynamic Carnot cycle. If you took the hydrogen and pumped it into a FUEL CELL, the reaction is far more effective (theoratical limit is actually a 100%)
    Fuel cells are already in use for power
    generation, notable example is the space shuttle.

    And, yes, abstracting the power source can mean more cleaner power generation methods (such as wind, tidal, nuclear, hydroelectric, etc).

  3. Capturing the controller signals for analysis... on Play Region 1 DVDs On A Japanese PS2 · · Score: 4

    A: Capture the codes for analysis, ie, sniffing the PSX controller traffic, and

    B: Using a PC to play back the signals?

    The PSX2 takes regular PSX controllers if I remember correctly.

    I imagine that the "40%" rate is because someone isn't entering the code properly. I don't imagine that the console designer included the debug code that would only work 40% of the time...

    * Even at 50% atmosphere, your eyeballs will be popping. Atmospheric pressure is 14.7 psi, 50% atm will mean a difference of 7 lbs per sq inch.

    * Why would you want to transmit "DNA" as 3D coordinates? Woudn't transmitting it as "AGTC" be a LOT more efficient? And even if you *did* transmit it in 3D coords, you would still need a forth character to denote the DNA nucleoside bases. And, man, do you have any idea how big the Human DNA Genome is?

  6. Re:Correction on New And Improved LCDs · · Score: 1

    Make sense.

    LCDs work by blocking light. So, to make a panel to give off N brightness unit, the backlighting must be at least N bright, but it has to be brighter because even in transparent state you will not get 100% light transmission efficiency. (Even regular window glass only transmit 90% or so or light, I think).

    LEDs work by light emission. If the LED emit N bightness unit, you only have to feed in the juice to give N brightness unit to get a N brightness unit panel...

  7. Correction on New And Improved LCDs · · Score: 4

    If you read the article, you can see that this is *NOT* for LCD use. It's an L*E*D display.

    LCD displays work by having an optically active (chiral) organic molecule layer (called the liquid crystal) sandwiched bewteeen 2 layers of polarizing filters, set at 90 degrees angle. When a current is applied the orientation of the liquid crystal layer changes, and the light's polarization plane doesn't get rotated the 90 degrees to clear the second filter. (Thus appearing to be dark). Take away the voltage, the crystals returns to ground state, plane polarized light is rotated 90 degrees, and it clears the second filter and appears to be transparent. This is how LCD displays on calculators work; color displays built on this principle and add a backlight on the back (ie, laptop) and by controlling the amount of light that passes thru for each pixel, generates the different colors. Note that the light emmision criteria has nothing to do with the liquid crystals; that's why you can't read your calculator in a dark room, and that's why palm devices have a backlight. Another cool thing to try is to take a polarizing sunglasses and hold it between your eye and the laptop screen and rotate it slowly. The display will get darker (at 90 deg) and brighter again (at a full 180 deg).

    Now that we have amused ourselves with LCD technology, let's take a look at what these guys at Princeton actually did:

    They found a new material that can be used in light emitting diodes. LEDs are used for indicator lights on the electronics that we all love. Traditionally, LED displays for flat panel applications are problematic for 2 reasons:

    A: Making the pixels small enough, on a large display.
    B: Finding a materials for blue LEDs.

    The problem with blue LEDs was solved a few years back, but as far as I know A is still a limitation. If you ever look at those big "SonyTron" LED displays in stadiums, up close the pixels are about the size of your THUMB.

    In order for this to suceed, there needs to be a good commercial process to apply the OLED material onto an (ideally) plastic substrate. Plastic substrates are really the way to go because they are less prone to breakage and don't require massive retooling. Hopefully, since the material is organic in nature, incorporating it onto plastic won't be such a difficult idea.

  17. Just name the algorithm after him and move on. on IDCT Approximation: Worth a Patent? · · Score: 1

    I'm a chemistry major and math minor by training. Most of the important lab processes are named after their inventors (Kjedhall nitrogen analysis, Benedict's solution, Tollen's test, etc) and quite a few mathematical theorem are named after their discoverer. (Green's theorem, Stoke's theorem, Kepler's laws, the Bernoulli equation). The way I see it, patenting this is leading to a world of trouble:

    1: How are we supposed to teach future generations this technique? Are we going to have to license the formula in a textbook on a per usage basis? Readers (University printed textbooks, in a binder) are expensive enough with all the copyright royalties.

    2: If someone used a similar process to calculate FFTs, or do derivative work on the theory (which is the very basis of science - taking existing theory to model new ones) how the HELL are we going to do work with patents on something that basic?

    Personally, I never expect to get a nobel price (or Field Medal (?) for mathematicians). If I get a chemical process named after me, to be printed in man pages and chemistry books, I'd die happy. And for most scientists I think that's one of the ultimate honor.

    Conversely, I'd never want to go down in history book as the S.O.B. that patented something basic and spent the rest of his life suing people for patent violations. Or hiding secrets from others (a notable example of that would be Hooke, who discovered Hooke's law. He didn't publish it because he stood to benefit from being the only person to mathematically model springs. It wasn't until his death when he made references to where the equations were hidden).

    Of course, I'm not saying that he will be running around suing people for patent violations. But then ... who knows?

With a toaster, I can load the bread in advance, pull it down, and power it on to toast. Rice cookers are great because they'll steam veggies (I'm a healthy geek), make marbled eggs, and cook certain meat dishes. I use my tea maker for tea and coffee, but if I get desperate, it works great for instant noodles too 8)

    Look at the patent file, and take a good look at the amount of correlation to the keystrokes to the characters they represent. Now look at Graffiti.

    It's obviously 2 very different systems. Graffiti is adapted from block print of the English alphabet; in cases where the alphabet takes 2 strokes to complete, graffiti uses one of the 2 strokes as the input sequence. Example, A is written as a upward pointing carat, without the bar in the middle, K is written like the less than sign ( ). This method is extremely EASY to learn, and I can hand my visor over to a 10 year old and he'd be able to figure it out in about 20 minutes, given the instructions.

    OTOH, Xerox's system is based on route memorization. I know I would never use something like that.
