  1. Re:Effects on the family cat? on Canadian Researchers Create Wireless Charger For Electric Cars · · Score: 3, Informative

    Different type of charging system.

    The charging system in your references is working via induction - basically a transformer and the energy is transferred through an alternating magnetic field that creates a current in the coil on the car.

    The system that's references here appears to use a magnet to spin a magnet on the other side that then spins a generator. I'm not sure exactly how the intensity of the magnetic field would be different because the power is still being transmitted magnetically, but it's going to be at a much lower frequency. The induction charging has a frequency of 40KHz while this would be more like 60Hz.

  3. Re:Old technology is often still superior technolo on 7000 e-Voting Machines Now Deemed Worthless By Irish Government · · Score: 1

    The number of holes in the Diebold technology was simply incredible. There were ways to compromise the machines themselves, ways to compromise the software that counted the votes, etc.

    There was no way to run a recount. A recount consisted of saying "Yup, I added the numbers again and they're the same". There's no trail of ballots after the election to check. The machines just keep a count and when the election is over, they're wiped.

    Add to that the other issues of technology obsolescence and the machines needing to be stored for long periods of time between uses. Add in the difficulties of handing out machines to voting personnel who get an hour's worth of training.

    E-Voting is a solution looking for a problem. The paper ballots with optical scanning is as much technology as you need.

  5. Re:Why BASIC? What for? on Why Can't We Put a BASIC On the Phone? · · Score: 1

    Many of the system utilities for RSTS/E, a DEC PDP-11 operating system, were written in BASIC-Plus. That included the login utility. The older versions of RSTS/E came with the utilities as BASIC source so you could mess with them.

    BASIC-Plus was pretty advanced but it still lacked some critical things like scoping. I don't think it was possible to do recursion in it.

  6. Not fully baked on Rethinking Rail Travel: Boarding a Moving Train · · Score: 1

    Assume that you make the transfer at 120 km/hr, that means that if you want to have a 5 minute dwell time, you need 10 km of track to make the transfer. You'll need more track for a buffer to slow down in case there's mechanical difficulty or a passenger problem and you need to bring the trains to a halt.

    Now, a "tram" is typically a one or maybe two car light rail vehicle. Your HSR trains are typically 10 cars. Are you only loading onto 2 cars at a time? That's workable in rural areas but how do you handle the big cities? Or do you try to form the LRVs into a longer train to load up. Any LRVs that miss the schedule will really screw things up.

    This sounds neat but it's not really practical.

  8. Re:CSS and why I never bought into it on Opera's Haakon Wium Lie On CSS, Web Standards, and More · · Score: 1

    A large percentage of my company website is XML that gets translated into HTML via XSLT. On the plus side it works fairly well and getting our non-designer employees to update information in the XML files is straightforward.

    On the minus side, we've found it nearly impossible to find web designers who can wrap their head around the idea of making a template page or to write an XSL stylesheet. Typically I wind up with a monstrosity in HTML that then has to have the template ideas teased out of it. It might just be that we can't find sophisticated web designers here in Japan, though.

    I wound up learning way too much about XSL and XSLT to implement some of the things that happen in the site and there is a lot of damn strange XSLT code in the stylesheets. However, XSLT may be a monstrosity but I think I prefer it to CSS.

  11. Re:What could possibly go wrong? on Japan's Richest Man Outlines Renewable Energy Plan · · Score: 2

    There was a time when converting from DC to AC meant motor-generator sets (meaning exactly what it sounds like - a DC powered motor turning an AC generator) but today we have the technology to convert high voltage DC to AC. High Voltage DC is more efficient over long distances and, as noted, is better for undersea cables. Typically, you use DC for the long haul and then do a conversion, once, to AC and feed it into the high power AC distribution grid for relatively local distribution.

  12. Re:It's rocket science folks on Bezos Discloses Failure of Blue Origin Rocket Test Flight · · Score: 1

    I don't think that's fair at all. This is a VTOL rocket that takes off and lands all in one piece. I don't know if they'll be able to get it to being a Single Stage To Orbit (SSTO) but they're a lot farther along than NASA ever got at that game. The whole vehicle is reusable (like an airplane).

    The closest thing to this was the DC-X. DARPA funded it and they got it to the point where it flew for less than 3 minutes and up to 3000 meters (about 10,000 feet). It did not go supersonic.

    NASA took over the program and promptly broke the prototype.

    Then, NASA and Lockheed Martin poured over a billion dollars into the X-33 project and never got to the point of a finished vehicle.

    So, libertarianism to the rescue? Not necessarily. Pragmatism and a desire to actually fly something rather than mess around with paper studies endlessly? I'd say that's more of the driver.

  13. Re:Screen too small on Ask Slashdot: Ebook Reader for Scientific Papers? · · Score: 1

    There were some different ways to view PDF's but you couldn't change easily on the fly. Scientific papers tend to be formatted in multiple columns so it's not as though you can just page forward if you put it in landscape mode. You have to read the top of the first column, page forward, and then page back to read the top of the second column. Personally, I didn't like it, others may feel differently.

    I'm not in Nebraska so I don't have any first hand dealings with them. A lot of "publicly owned" or "non-profit" entities seem to be operated for the benefit of the management, not the public. It would be interesting to compare how OPPD works compared to, say, Pacific Gas and Electric (they cover Northern California), which is a for-profit utility owned by stockholders (but regulated as a utility). We used to like to call them Pigs Greed and Extortion.

    Hmmm...someone must have transposed some numbers. The main article on New Zealand (http://en.wikipedia.org/wiki/New_zealand), under Infrastructure lists it as being lists it as being 69% oil, gas and coal with 31% renewables. I'm inclined to believe the electricity sector page - I'd been looking at both but assumed they were in agreement and got the number from the New Zealand page when I was glancing at it. The numbers per sector on the electricity sector add up properly as well so the main page looks to be in error.

    New Zealand phasing out coal is a "good thing". I'd like for all countries to be working in that direction. My recent magazines from the US (I'm an American, living in Japan) seem to show the US heading towards natural gas from shale as the new big thing. Better than coal, but still burning stuff.
