shanghai day 5 ... last day of dream ...

the last day actually not much event ... wake at 0545 zzz ... army style ... then sit coach bus go sit mag lev train ... the last time i went to shanghai i was already trying to guess how it works and move ... but i was lazy to go search on it ... so i decided to ask elvina how to works ... she had the same guess as me how to works ... but she can't come out with how it moves :X ... my original theory is ... for it to be levitating the magnet are repelling and the weight of the train = the repelling force ... thats why the train will levitate ... and for it to move there are magnets that are attracting at the front and repelling all through the bottom of the train ... so there's circuits to keep changing the poles ... basically electromagnets ...

and after researching this is the real answer ... i can say my guess is very close ... at the bottom of the train is a type of material that has diamagnetic properties (a property that will repel any any magnet that it comes close to) ... and this material has to be super cooled to -200 degres before the diamagnetic property will kick in ... that is for the levitating part ... so the moving part ? ... attract at the front and repel at the back ... a slight push on the train will let it move already ... oh and another thing is how the track is arranged ... NSN ... so with this dimagnetic on the NSN it sort of creates a 'tunnel' for the train to move in ... this solves the mystery of the mag lev train in shanghai ...

okay so back to topic ... the train travel at 300km/h but its top speed is 430km/h ... after the train ride we are in the airport le ... so wait for the coach to reach ... and finally took a group 'kids' pic ... the rest of the pic will be in the last dreaming post ... then slowly wait for check in and ... off we go back to singapore ...
