Going underground for space solutions | Land Unlimited | Full Episode

Singapore and other land-scare cities transform underground spaces to become subterranean train depots, theme parks, reservoirs and more.

=============
ABOUT THE SHOW: What will Singapore be like in the future, as city planners, corporations and scientists find new ways to overcome land shortage? The ground under our feet, the sea around the island, even empty spaces above roads and canals might be used for transportation, storage, homes, offices and other infrastructure. The series showcases how other land-scarce cities Tokyo, Hong Kong, London and Helsinki use these unusual locations to overcome limited land, and what Singapore can learn from their experiences.

It's really interesting to know Singapore is already going big on going underground. I think the 3 level train depot is a very smart idea.

As a renewable energy scientist and someone who understands the value of land, I have always cringed when I have seen huge tracts of land covered with solar panels. Look at the width of the roadways and rail lines. The perfect place for solar arrays. Transit lanes where bright light and falling rain would not be missed. Get you panels 30 feet in the air where dust and debris does not like to live!

Turkey has ancient underground cities that were discovered fairly recently. I bet all underground builders could learn a lot from the design of those extensive ancient places

Thank you to all the smart and talented people in our civil services. You all are the true heroes, the real backbone of our country.

Montreal Canada is the leader in the concept and development of the underground city, truly impressive.

[beckysam]

That reminds me of the book 'The time machine', when human species splitt in two, one above the ground living the Eloi and one below or underground living, the Morlocks.

Singapore prospering now but facing enormous climate challenges in the future for a lack of land space, I'm lucky to be in a country with a huge land mass to be develop in the near future for my future clan.

It is a shame that so many governments cannot see beyond the next election. It takes vision and courage to build for the people for the future. Great report.

Ventilation is one issue I would like to hear more about. How do they provide suitable ventialtion for underground roads full of cars that are burning up all the oxygen?
Helsinki's underground service route for wiring and plumbing is truly ground breaking! Every city has the issue that it is hard to dig up old pipes and wires to fix them or lay new ones. That is one really fantastic idea!

[oumunfeiholeto]

I wished Australia has that kind of brains and incentive to build like some Asian cities.
This use of space is amazing.

[StudioArtFX]

I feel like this would never happen in America, *not* because we have so much space, but because so much development is focused on profit rather than people.

8:59 "Hey we need to optimize it"

Yes you do

If land is in great supply, then you optimize for other factors, such as cost, construction time, etc

If your engineers are able to only think in terms of a single dimension, ie optimizing for space, then no, it's not a sign of them being overly dedicated or anything like that, it's simply a sign that they have a one track mind

Indonesia hrs belajar dari Singapura dan Tokyo untuk membangun kota moderen.
Karena ada kesamaan jumlah penduduk dan kepadatan nya.
Kota Bandung hrs belajar dari kota Hongkong yg sama wilayahnya pengunungan dan bukit.

Love your videos - sometimes the background music though is louder than the speaker and cannot hear him.

[SportsIncorporated]

If you go down deep enough, it gets really hot.

[terencegalland]

Wow what an amazing city state Singapore leads the way😍

[alantan]

11:18 Singaporeans are creative. If you charge royalty for such ideas, it would be a huge export earner.

Survival is the mother of all invention.

[aranbarrett]

Adleast there are some countries that care for their future generations not just thinking of them selves very interesting .

[tomkelly]

Floating cities are an excellent idea! There is so little land in our tropics! Lets make floating cities to increase then number of places to live in our worlds goldilocks zone!
