He works on Project Loon, Googleâ€™s ambitious plan to deliver Internet service from enormous balloons floating in the stratosphere. When the company revealed the project in the summer of 2013, these polyethylene balloons stayed aloft for about five days. As part of Googleâ€™s effort to increase their flight timeâ€”and turn them into a viable way of getting underdeveloped regions onlineâ€”Krishnaswamy runs what he calls The Leak Squad. Using everything from mass spectrometers to soap bubbles, these Googlers scour the balloons for even the tiniest of leaks and explore ways of changing manufacturing, shipping, and handling methods so these leaks are eliminated.
Typically, Krishnaswamy and his team examine and test the balloons in one of the iconic blimp hangars at Moffett Field, the old NASA airfield down the road from the Google X research lab in Mountain View, California. Hangar Two is one of the few places big enough to house these 30-foot-long balloons, and it happens to be in the neighborhood. A Google subsidiary is leasing the airfield from NASA so the company has a place to park its corporate jets and test things that donâ€™t quite fit into an office.
