Hi Stefan,

Well the good news is: NO there is no need to push to get it started.You  
just let go and its off it does seem to pull into it!!

The bad news for me is I still have not received my Magnets, but whilst
I was choosing what I consider to be the correct type I did hold  
theconfiguration in my hand. The roller just four magnets stuck together
did appear to move or rather shoot forwards until it stopped between the
end of the two rails held in my hands. The ramp needs a downward slope
so the roller just drops out of the field with gravity but I don't know, if it
needs the momentum to start climbing the next ramp! (I don't know till
I build one though.)

Some tips?
1) The magnets I have ordered are 25mm Dia 5mm thick. They are magnetised
   through the thickness north to south but NOT in stripes or multipoled.
2) The fridge magnets others mention are not always magnetised through the
   thickness, I nearly ordered 100 for 5.99 pounds, but they were magnetised
   strongly on one side only and in stripes and do not work at all!

MRA update.
Some one has reported a low power MRA made with a Capacitor instead of a
piezo and a common magnet from Radio Shack supplies. He says he has got
10 times O/U!
Meanwhile, the inventors are not withholding further information they
are going to release more info later rather than sooner as they are making
good progress but they have not yet put together the self powered mode!
