The new stone age.

This article reports on the building of a bridge with a reference to the book of Roelof Schuiling, an engineer. A geochemist at Utrecht University in the Netherlands, Schuiling has spent 15 years developing an extraordinary construction technique that could see rock bridges, walls and dams sprout from the seabed, driven by the power of chemistry on an unprecedented scale. The project could even help to dispose of millions of tonnes of waste acid from India's chemical industry by locking it up in the fabric of the bridge. Earlier this year, Schuiling read a scientific paper that suggested placing wind turbines on the string of reefs and islands between Sri Lanka and India called Adam's Bridge.
