6.5 million people is a big squeeze Far from it. If we plan properly, build upwards and downwards and using the best technology, Singapore can easily take in 30 million. Just build the whole island like the Tower of Babel. Use steel and glass. Yes a lot of glass, like a glass tower towards the heaven. We will be the most futuristic city, fully airconditioned, and several layers over layers. Bukit Timah will become a mole hill when all the surrounding buildings are 3 or 5 times taller. And we can connect everywhere, at different levels, with travellators. No need cars and no need petrol. With the whole Tower of Babel adapted to become a solar cell, we can maximise the use of clean solar energy. That will be the future of Singapore. A glass city of the future, built by the best minds money can buy.
