    1) LOL, if you believe less energy is consumed at higher RPM in an electric motor, I've got perpetual motion machine to sell to you. A transmission allows you to operate the car at highway speeds at a much lower engine RPM.

    2) No gears means lower top speed.

    1)An ICE does not have the same performance characteristics as a motor. For starters there's a lot more friction losses. Take an ICE up to max speed in neutral and kill the ignition. Doesn't take long to coast to a stop (see also engine braking). This effects speed vs power vs efficiency. Bring an AC induction motor up to speed and kill power... it will coast for a long time. Even running at full speed with no load other than the gearbox I've seen big induction motors use no more than 2% rated power.

    2)There will normally be a fixed reduction gear ratio (since the wheels won't spin at 1800RPM). This ratio will be chosen based on desired top speed.

  2. Re: FP! on Why Electric Vehicles Aren't More Popular · · Score: 1

    It depends on the type of electric motor. A typical polyphase AC induction motor will only provide 150% rated torque at 0RPM, but will peak at 250% rated torque at 75% synchronous speed (slip of 25%, meaning you loaded down the motor such that it slowed down 25%). With a VFD, line frequency can be varied to provide this at any frequency, but you're still limited at 0RPM. Obviously you can't run forever above 100% rated without overheating the motor. A DC shunt wound motor can provide any amount of torque from 0RPM through to rated RPM (limited by the control system, typically to 150% but I've seen them run 250%)

    However an AC induction motor (and shunt wound DC) can provide 100% rated torque at any speed from 0%-100% rated speed, which is why they can be run without a multispeed gearbox if speced properly. An induction motor, unlike an ICE (or wound rotor, or brushed DC, or Synchronous motor) also has no other wear parts than the bearings. Specced properly, lubricated, and kept cool, these bearings, and the motor as a whole can last for years at 100% power output at 100% speed.

    I got fan errors on my old Thinkpad if I left it off for a couple days. The trick was to press Escape while powering on... The fan won't start but it will let the computer boot, and is suitable for light duty work. After letting it warm up (sometimes 1 hour, sometimes took a couple days), I would try to reboot. Eventually the fan will catch and start spinning. Then it's good as new as long as I don't shutdown overnight. I did try both duster and vacuum, to no avail.

    The laptop ran 3 years like that. And I avoided the IT department, so no lecture on backups, and no having my computer blown.

  7. Re:2 words: lockout, tagout on Volkswagen Factory Worker Killed By a Robot · · Score: 1

    Having worked with European industrial equipment, safety standards are very robust over there as well.

    While Lockout-Tagout is the only way to guarantee no energy when working on a piece of equipment, sometimes the job doesn't allow that. Troubleshooting a problem, or an adjustment / training procedure may require the equipment to run under power. Same with a material load / unload process by the operator.

    Risks in some of these situations can be minimized: Safety rated light curtains may detect an operator and slow the speed, deadman switches / e-stops may be manned during the procedure to allow for an immediate stop if something isn't right. However no matter how good these planned safety procedures and systems are, someone will come up with a scenario that wasn't foreseen.

    This isn't to say that it's an unfortunate accident that couldn't have been prevented... it probably could have been prevented. Either the worker wasn't following the rules, or there weren't proper rules for what the worker was trying to do.

  9. Re:You can still buy Windows 7? on People Are Obtaining Windows 7 Licenses For the Free Windows 10 Upgrade · · Score: 1

    Yep, software resale is legal in the EU, so you can buy used Windows licences. Of course, you can probably just get them for free at the local rubbish dump... Maybe that's why Microsoft stopped printing the key on the stickers for OEM copies. Can't recycle them if the machine is dead and won't give the key up.

    In places where resale isn't legal Windows 7 costs the same as Windows 8 and Windows XP. Microsoft keep the price the same of the lifetime of the product, it's never discounted.

    Genuinely curious, in EU are OEM licences legally transferable to another machine? Microsoft's intention is that Retail licences are transferable, but OEM (sticker on a machine) are not.

    Since Windows 8, Microsoft changed their "System Locked Preinstallation" (SLP) OEM procedure, so that the individual key is baked in the BIOS / EFI. It will populate itself when a Widows install disc is used.

    I think the reason for this is that on Windows 7, large OEMs (like HP, Dell, etc) used a generic key for each brand, and this method of activation was the method of choice for pirates (eg: Daz Loader), which proved very bullet proof, so they wanted to get rid of that as a piracy path.

    -Corporate users have been the biggest holdbacks for XP. My company didn't complete their XP->Win7 migration till the end of last year, with no plans for 8 / 8.1 / 10.

    -Anyone looking for a free upgrade to Win10, although my understanding any "non-genuine" version will be eligible, pirating Windows 7 is more bullet-proof than Windows 8. Windows 7 has Daz Loader based SLP based activation, vs. Microsoft toolkit based KMS only for 8/8.1.

    Agree, unfortunately it's getting worse. And this isn't a new thing for Java. Ask Toolbar, and other shovelware has been included before. At least a browser search engine change is fairly benign. Flash keeps trying to install a junk McAfee security scan (that can conflict with AV software)when doing updates. uTorrent (the once mighty Torrent Client), tries to install Conduit browser hijacker. Even ImgBurn, the once great CD/DVD burning tool now has OpenCandy Adware junk bundled.

    Download.com used to be a safe place I could direct people to download software. Now it tries to install junkware. SourceForge tried to bundle adware with people's open source projects.

    For now at least Ninite is a safe place to get a lot of essential software without opting out of installers. Another trick that works is a lot of Adware won't try to install if there isn't an active internet connection.

    Well, you screwed up. Windows 2003 is based on XP-64. You should've looked for XP-64 drivers and they would have installed just fine.

    There's two problems with that:

    1) There sure as hell is a 32-bit version of Windows 2003, and these were definitely 32-bit machines
    2) The drivers simply did not exist. Dell had never made them for Windows 2003

    Not only is there a 32 bit version of Server 2003, but XP-64 is actually Server 2003-64. XP64 is (/ was) maintained at the service pack level of 2k3, and 2k3-64 is probably more popular than XP64 which very much was a niche OS.

    In any case, XP-32 bit drivers (if you can get them) should work in server 2003 given that Server 2003 is newer than XP. To get Intel i815 video chipsets working in Windows 7, and other antique hardware in a PIII I've had to grab drivers from Windows 2000.

    In your case I've seen ways of extracting drivers from a running installation to get it to work on a new install. In my experience the bare minimum is: Storage drivers (if it can't run in IDE compatibility mode, it won't boot), and network drivers (to get online to Windows update. You may be able to use a USB NIC if you have drivers)
