Anyone watch this show on the Discovery Channel? I have caught two recent episodes late at night which have spawned on interest. I have a feeling this is right up Brent's alley.
The first one, I only caught the end of it, was about the new stadium they are building in Glendale, Arizona for the Cardinals which has a retractable playing field.
But the one which really got me interested was the Stormwater Management and Road Tunnel or SMART Tunnel.
It is pretty nuts and sort of hard to explain but the gist of it is that the Kuala Lumpur, Malaysia has problems with flooding so they are making this tunnel which will run under the city which has 3 levels. The bottom level will be a storm tunnel for the water while the top two levels will be a tollway to help out traffic but if the flooding is that bad, it can shut down the tollway and make the whole thing for water.
They are still in the process of making it and that alone was interesting as they have these two drills/machines that are the size of a 10+ story building on its side which drill out the path as well as put up the concrete walls, sort of 2 in 1 machine.
The one thing I found odd is that the tunnel can't be a straight path as land owning laws in Malaysia say if you own the land, you own the ground beneath as well (all the way to the center of the Earth apparently) so they have to dig out this tunnel to follow the highway which makes the project that much more difficult.
Anyways, I recommend watching this show when it is on.
