Huge winds generated by MRT trains?!

don't get me wrong.....what i said is, if there's medication for an illness, then when you get that illness, at least it's not so bad since still got cure.
imagine you get AIDs (choy!).
you go see your family clinic doctor.
he gives you injection because there's already a cure for AIDs.
at night, u feel so well and alive and healthy again.
that's an example above. i'm sure most people won't be even scared of AIDs even if they get it, as long as there's a cure (like your normal fever or flu, where u see family doctor and get well in 1 days time etc).
of course, we know currently there's no cure for AIDs due to the "very efficient work of those highly talented scientists". just an example.
So what now? U r trying to said u are better than those scientists?

not sure if u guys experience this before, but in underground stations, it seems that when the outer doors close, there's this really huge gust of strong wind that just blows out from the doors or something......
can anyone explain?! i'm not sure if all underground stations have this effect, but tanjong pagar mrt which i use everyday seems to have it.
if you want to experience, then around 6:30 PM, wait there for half an hour and i can guarantee you'll experience it a few times at least.
the wind is comparable to very strong beach winds......something like a wind tunnel with immense winds blown into it.
not sure if this is due to the mrt propulsion system?!!!! maybe some expert can clear this thing up. the wind is strong enough to destroy your gatsby hairstyle.
this is e wind created by other trains when they are in an enclosed area (a tunnel for this case) -

I think the problem is that since the wind from these tunnels is generated by artificial means, we get a net loss from building the infrastructure to draw power from it.Meaning in the end, we waste more power from doing it than the amount we get in return.
My colleague once mentioned to me the idea of installing solar panels in office to get power from our lights.

The large mass of wind that the train displaces when it arrives in the station has to go somewhere. Initially it would go to the front and back of the tunnels, but the train doors open and the wind is diverted into the many openings in the station.
Not many people are aware but below the platform(underplatform) they are standing on, there are a few tens more openings each with its own adjustable sliding grille doors each the size of a small window.
They are all linked by a masonry duct to the underplatform exhaust fan room which blows off the warm train exhaust when they come in to the vent shafts outside.
Without the use of such, all the glass platform doors will blow into pieces everytime a train rushes in.

Let's just say, I've done my share of MRT projects.

its air pressure... the trains in the tunnel push the air..
wnat some expiriments??
try take the injection thingy or something like a pump and try to press ..
there will be wind..
its goes as same as this..
when u stand at the end of the platform, try to feel the wind at the door while the train is approching in 1 min..
or observe the door and you can see the door is like someone is trying to open..
its a wind.. so its air pressure -
so??wat u want to do harvest the wind to power yer computer?

damn,,,,,i knew eating laksa n kuay teow has side effects for sporeans until they discuss n mystified bout wind from mrt tunnel even.i thought all of u go thru the education etc end up talking bout wind from train??arrrrrr!!!??like that how to have future ??
-
the effect can be easily explain in 3 simple points
1 - train move fast
2 - train push wind
3 - wind move fast
