  1. Re:Amazing performance on Electric Car Drag Racing · · Score: 2

    There's one big advantage to electric powered cars when looking at it from a Drag racing standpoint: full torque is available from 1 RPM. compared to the popular internal combustion engines for drag racing (V8 or turbo'd imports) this is an amazing advantage. A typical V8 will start producing useable torque by 1500-2000 RPM, and peak around 3000. Turbo'd cars (mainly seen in the import drags) are even worse. The torque curve there is dependant on the turbo being at full spool, so it's a slow build to a peak around 5000 RPM (generalizations, but good to make a point). This translates to wide ranges of the power band that are for all intents and purposes un-useable for the race. When you have a power supply that is at full torque from the moment you step on the accelerator, and holds that through the entire band, your biggest hurdle is in keeping the tires stuck to the ground. The hard part of translating this advantage to street vehicles is in the range these cars have. They have been designed to go a short distance at full power. It equates to the funny cars and rail-dragsters that only have a 5 gallon fuel cell, and it has to be re-filled after each 1/4 mile race. Having any engine run at maximum power generally makes for a very short range.

  2. convenience is the key on Would You Ever Read A Newspaper Again? · · Score: 1

    there have already been great points made regarding the newspaper's advantage in reporting local events. I think another key issue to me is the convenience. The local daily paper is delivered to my doorstep at about the time I get up in the morning. Therefore, I have an easily accessable recap of the previous day's events to peruse as I drink coffee, eat breakfast, and generally get ready to face the day.

    While the user interface may be clumsy, the added advantage of near instant obsolesance is handy. If I spill my bowl of cereal onto my computer, there's a risk of damage to equipment that's financially unfeasable to replace often, but if I spill on the newspaper, I've only lost a portion of one day's news...the next day will bring another "upgrade".
