    Global Warming? Not up here by any accounts!

    Ok, last night the temp outside was -42c static with a wind-chill dropping the cold index to -57c. Yes that’s right minus fifty-seven degrees Celsius!

    Tonight the static temp will be -41c and the wind-chill of -58c due to the slightly higher winds. (I’d say it time for some ice diving!)

    What does this mean in real terms? First off, if your car breaks down on the highway, and you are alone in your car for more than 2 hours, you will die! End of story! When you start your car in the morning, after it warms up enough to move, about 10 minutes minimum, the part of the tire that has been sitting on the ground over night is flat, as are all tire regardless of temp. However in this weather, they stay flat for about 10 minutes into the drive, causing the car to bump down on every tire rotation. If you slam the car door, you run the risk of cracking or completely breaking off the weather stripping around the car door. The material has reached its freezing temp and has become brittle.

    On the good side, there are absolutely no panhandlers, squeegee kids, or vagrants of any kind on the streets. They have all moved to Vancouver by this time of year where it is warm, and flowers are growing. In light of that, I’d have to say the cold isn’t that bad after all.

    If we are going to start speaking temperatures here is something I stole from my boys over on the Refrigeration site that I read every day..............

    Eons ago I worked with an Engineer we called "Herman the German"..Real name Gerhard Neuman..
    He always astounded us with wis mental conversions of °C to °F so quickly...Finally he told us Yanks how he dood' it.
    Without fractions & in yer punkin' head...

    Double the Temp(°C), subtract 10% of that number from itself, then add 32....Presto!!~!~! We now have °F.

    Ex: 100 X 2 = 200
    200 - 20 = 180
    180 + 32 = 212

    Ohhh yeah...That Herman the German guy finally got his lil' jet engine working, the first with variable stator blades....

    Pretty good huh? But it doesn't work going from F to C. I think you have to use 1.8 or something. It is more complicated.

    Most myths are false, except that one is true!

    Yes, your spit will freeze before it hits the ground in this temperature. Unless your only 3 feet tall and the snow bank is level with your face of course.

    Hey Padivers, you can always come for a visit in the winter and get your fix of ice diving you know, and then, maybe not.

    And about being trapped under the ice, never to be heard from again. Well H2Andy, that does happen when they go under without proper training, or preparation. Just as in caves and wrecks, under the ice is no place for inexperienced or foolish divers. It will show no mercy and take your life without prejudice.

    Here's an easy formular to convert F->C

    C=F/2 - 30

    Ex. 80F/2-30=10C That's not exact to a degree, but close enough.

    If it's stupid but works, it isn't stupid.
