Back in 2013, scientists at NASA were baffled at rate of which the Ares rocket was shaking. Realizing that astronauts aboard could become seriously hurt, they pursued a solution that would provide weight to the heaviest part of the structure. This technique is commonly used in construction to stabilize buildings, such as the Taipei 101 in Taiwan, which uses a 730-ton gold ball on springs to secure the skyscraper. But there's issues to these massive structures that mitigate these structure's swaying motions. For one, they're crazy expensive. The other is that they take up space that could be used for other projects.
So when NASA saw what they could do with a rocket, they figured why not a building? To come up with a proportional answer, the scientists calculated the liquid's frequency to match the vibrations of the rocket. The final product was less than 100 pounds and made the rocket 20 times more stable.
To apply this to a building, the scientists can determine the frequency of the building’s motion. The latest product is called a disruptive tuned mass (DTM), and most recent iteration of it is the size of a coffee can. The first commercial property it was integrated into is the Tower B2 at Pacific Park, in Brooklyn, New York.
