    Yes you know what you remember, but you can't know for sure if the memory is based on your personal observation or that the memory is based on information later told to you and some later memories of the smell and so.

    Here some examples of which I quote one, it's not exactly the same as this case is a 'real' memory of something that never happend...
    Conversations with Jean Piaget, see page 120 bottom + page 121.

    Eleventh Conversation - Memory: The Kidnapping of Jean Piaget - starts on page 118.

    Your mother could be right . . . . . :cool:
    as they are most of the time ;)

    Well Phil, if I had my "druthers" I'd keep my feet firmly planted on the deck thank you very much! :D

    I guess when I was younger I would have tried pretty much anything but a 1700+ foot tower? Hmmmm? Nope not this kid!

    I did fall from a tree once. Hung upside down by my heel until my Momma found me about three hours later! :eek:

    And fell from a bucket recently . . . . . :p

    BTW, watching the tower climb vid made me dizzy and a kind of seasick, it was a nice view though . . :)

    Cheers,

    Just like Occupy Wall Street.

    Maybe it was grass. ;)

    I think it's a real memory. We were inside, but on a wooden walkway with stalls on either side, and I was watching the walls, the electric lights and the backs of the cows wobble around while my dad walked.

    I also remember seeing cattle when I was older and telling myself, "oh. That's what those big old things were.... cows!"

    Until I described the memory to my mother when I was in my fifties, I had never mentioned it to anyone. I also didn't know anything about my dad working at a dairy in Oregon; the stories I heard growing up all had to do with him being a logger. But it's possible we went into a barn for some reason when I was a little older; my parents didn't move back to California until I was almost three years old.

    An old Lithuanian friend of the family would be proud of these contraptions!

    George loved to do things himself, on the cheap.

    Cut down a tree? Why pay professionals when you can just use your own
    pants belt to lash yourself to a branch and use a chainsaw.
    Result: a smashed leg and 4 months in plaster.

    Home-made ginger beer had a little alcohol, so why not increase it by using
    more sugar.
    Result: He couldn't go down into his cellar for over 5 years while bottles
    were still exploding.

    Crayfish tail makes excellent bait. If you don't catch any fish, why waste
    the cray tail? Why not cook it up when you get home?
    Result: 2 weeks in hospital with severe poisoning.

    The last one with the rotor masts must be under power. The sea state is low and they seem to be doing better than half of hull speed looking at the waves. Aren't these 'power assist' devices? I am ignorant on them.

    "The E Ship 1 arrived in Dublin last week with a cargo of wind turbines manufactured by Enercon. What was striking was the ship itself, with four tall pillars rising vertically from the ship, two forward and two aft. The pillars are Flettner rotors, first developed in the 1920s by German engineer Anton Flettner. They are in essence, motor powered sails, 27 meters tall and 4 meters in diameter. The spinning vertical rotors develop aerodynamic lift using the Magnus effect. As the wind blows across the spinning rotors, they develop lift similar that of an airfoil shape of a conventional sail. Unlike masts and sails, however, the vertical Flettner rotor does not interfere with cargo operations. The Flettner rotors are expected to save 30-40% in fuel costs at 16 knots.

    The E Ship 1 is owned by Enercon and is intended to demonstrate energy saving technology as well as to deliver Enercon wind turbine assemblies to customers. In addition to the Flettner rotors, the ship is powered by diesel engines driving twin propellers. Exhaust gas from the engines power a downstream steam turbine, which drives the four Enercon-developed Flettner rotors.

    Buckau

    The basic design of the Flettner rotor has been around for almost 90 years. Flettner applied for his patent on the design in 1922. The Flettner rotor ship Buckau set sail in 1925, first crossing the North Sea and then the Atlantic. While technically successful, the low cost of fuel and the limitations on bearing design made conventional ships more cost effective.

    With advances in engineering and dramatically higher fuel costs, has the Flettner rotor finally arrived as a viable technology? Time will tell, though it is interesting to read the predictions of F.O. Willhofft, former Professor of Mechanical Engineering at Columbia University, as reported in the New York Times on May 3, 1925. In a paper given to the American Institute, he wrote:

    “The outstanding fact is that rotating cylinders produce about ten times the propulsive force as canvas sails of the same area and that the actual results obtained in the trial trips of the Buckau confirmed the laboratory results with remarkable exactness.

    “All that one can predict with certainty, basing the estimate with actual results obtained on the Buckau and on meteorological statistics, is that a motorship equipped with rotors will save not less than 25 percent on fuel , on the average, year after year, for the average trade route. I consider the Flettner rotor ship as a link only in the chain of evolution of the harnessing of wind power. “

    Eighty five years later, the E Ship 1, may finally begin to prove Professor Willhofft right"

    Last Saturday at Ft. DeSoto County Park on south end of Mullet Key.

    Cruising last summer and I wish I was there now. It's freezing here today.
