  1. Re:Heat? Hills? on Hybrids Beware? EPA Revises Mileage Standards · · Score: 2, Informative

    Hi,

    I did the hill calculation for going over Barlow Pass in Oregon (Mt. Hood..) before I bought my 02 Prius. Don't have it, but I remember how I did it: For your example...

    calculating vertical climb horsepower.. assuming grade is rise/run proportion.

    Given that 1 horsepower is 33000 pounds 1 vertical foot up in a minute.

    50mph is 0.833 miles/minute. at a 7% grade up, its 0.05833 vertical miles, or 308 vertical feet/ minute.

    3500 pounds of car and load, that's 1.08e6 feet*pounds lift per minute.

    1.08e3/33000(ft*lbs/min)/hp gives about 33hp for the vertical climb, leaving 42 hp for friction (aerodynamic and road) I believe this car only uses about 14-15 horsepower for friction and windage at 60. Even derating for loss of power at altitude, (70% at 10000ft?) there's still margin to do this.

    Huge horsepowers in modern cars (>100HP) are not needed for climb, they're used for acceleration performance.

    Now.. accelleration 0-60 in the 02 Prius is not great. It's fantastic 0-20, okay 20-35 and terrible from 35-65. I believe the '04 version and up really improved that by doubling the electrical torque. The surge torque you get from the electrics are not affected by altitude, which can be nice.

    A bigger concern might be the cold weather performance. I've noticed occasional starting issues in the 02 Prius under sub 20's F. Basically, if the car can't start itself on the first crank over it freaks out and lights up a lot of scary indicators. I've had this happen 3 times. I believe they've got a fix for this on the car.. I'm of the mindset to just not care as long as I understand why the indicators are up when this happens. Of course, I live in a valley where it rarely gets under freezing. I would be worried about sub zero F temps for this vehicle.

    The Hybrid is started by the traction battery.. so in theory... they could give it far superior start performance in cold weather.

    Cheers,

    Alex

  2. Well, I guess I'm not a customer anymore! on Novell and Microsoft Claim Customer Support · · Score: 2, Interesting

    I run Suse on my machine, a desktop I depend on every single day for engineering work. I wasn't thrilled when Novell bought Suse, but I upgraded to Suse Linux 9.2 anyways. It says "NOVELL" on the box. I think it was about $80.

    Well, guess what. Next time I build up a new 'puter or upgrade the OS on this one... I'm not going to use Suse, even thought it may not be as seamless a transition for me.

    I feel a little bad, because the Gecko is kinda cute, and the "random phone support lady" that came up on the while-installing screen was really really hot (I cannot be the only one to notice this). But I depend on Open Source Software and I know who my friends are and aren't.

    Becuase I don't like the deal, I'm not a customer anymore, and wouldn't be involved in Novell/Microsofts little survey. Does this prove my point or prove theirs, or both??

  3. We already have a source of fusion power. on Green Light For ITER Fusion Project · · Score: 1

    We already are extracting useful power from fusion.

    The reactor is 93 million miles away, so the energy density collectable isn't great, but it's super reliable. The extraction can be done by a simple diode junction, with no moving parts.

    40 years ago photovoltaics were so expensive they were only used in the space program. 20 years ago they were cheap enough to be real practical for isolated power needs. Maybe 10-15 years ago we started seeing highway road signs use them. Right now, the cost is down to the point where private citizens can turn their homes into net generators http://www.pvpowered.com/. If the cost per watt of photovoltaic capability keeps on this trend, in 20 years, we'll be generating massive amounts of electricity from the sun.

    I'd like to see funding going to ITER.. it's awesome and inspiring science and engineering. Frankly, I'm bummed we're not doing both this and the superconducting supercollider here in the states. But right now, we need massive investments in known-working non-carbon emitting energy generation.. wind, photovoltaics, and maybe biomass with carbon sequestration.

  6. More prayer for control group? on Prayer Does Not Help Heart Patients · · Score: 2, Insightful

    I don't understand the mechanism by which prayer could help. I cannot conceive how G-d could care more about a person prayed about than a person not prayed about. So I can't easily come up with any method, either scientifically or "religiously," where prayer would improve outcomes, (Disclaimer: I'm just a confused citizen of the world, not a theologin) but I pray anyways. If I hear somebody I care about is terribly ill, there's no usually no logical action I can take. Prayer makes me feel a little better about the situation.

    I can come up with a way their control group could've been badly polluted. Some, perhaps many, "prayers" may have felt that it would be unethical or uncaring to not pray for the control group. So if every person in the study gets a prayer or two, but the anonymous control is getting the combined prayers of many, well, the control group would get more prayer. "Anonymous" means nothing to an omnipotent, omnipresent G-d.

My last day there, I had to drop my keys thru the mailslot on exiting, cause I was the last one out the building about 1030PM.

    Somebody got a hideously exploded drive.... (we made 480V 20HP machine drives,) and everybody signed it and gave it to me.. it's still one of my treasured possetions...
