Well, I could make a special photo from the backside, which is normally
not very interesting for postcards, ;-)  but for us, the technicians,
it is!  If it makes you happy, I can act like turning the crank, but
WOW it's heavy!  I never made more than 14 double sides of a book, and
had to finish!  (And I have to turn with both hands if I want to do

It normally runs by a motor (220V).  Lately we got a motor that can
be regulated, but the regulator is in our 48er.  Still looking for
battery-running motors that do their job for at least 5 hours, can be
regulated in speed, too, and not being too expensive, and not having

ERlanger drehORGEL-Trio, Familie Krause,

 [ I thought that the street organs in Holland, performing for money,
 [ were required to be turned by hand.  But I saw the wonderful big
 [ "Julius" in Maastricht, powered by a very quiet 4-stroke-cycle
 [ gasoline engine.  I sat on the sidewalk, 3 meters from the organ,
 [ and the engine noise was barely audible.
 [ The solar-powered electric race cars consume, and produce, 1 kilowatt
 [ electric power.  1 horsepower at the axle propels the vehicles at
 [ about 65 kph (40 mph).  On the top of your trailer there is a surface
 [ area equal to the race car, probably even more.  But you need a big
 [ battery to operate after sundown !  -- Robbie
