Thank youfor your question about the balloon planning algorithms. Our team had the same question at the start of the project: can balloons that are constantly moving around in the stratosphere provide stable Internet coverage to people on the ground? To explore this question, Dan, one of our Rapid Evaluators, created a simulation that uses hypothetical balloons and real-world wind data. In his model, areas with no coverage appear dark blue, while areas with good coverage are light blue. The results have been promising.

Great question about whether hurricanes affect balloons at 20km. They do, but maybe not in the way you'd expect. Balloons at 20km are well above the wind, rain, and other inclement conditions associated with hurricanes. However, it turns out that the tops of clouds are really really cold, and hurricanes create a large swirl of thick cloud above the Earth. This ends up blocking most of the infrared radiation that would have warmed our balloon from below. Instead, it's as if there's a giant heat sink below the balloons, cooling them to extremely low temperatures.
We have to be careful with this, because if superpressure balloons get too cold, they lose their superpressure and descend out of the sky. By carefully planning a balloon's trajectory over a hurricane to ensure it doesn't get cold enough to lose superpressure, Loon should be able to navigate through these storms.Nov 14, 2013

- Hey i need a PowerPoint presentation on loon project can anyone help plsFeb 11, 2014
- You mentioned local ISP will be used to provide the Internet in one of the videos. Does this mean the ISP's of that particular area? For example If someone connects to loon from Bangkok, Thailand, will his request be routed through local ISP's of Bangkok or other regions? #AskAwayMar 22, 2014
