Rising global temperatures are also raising worldwide concerns about wildfires like the ones surrounding Los Angeles this week. While the most common way to detect forest fires are visual — often the naked eye — the concern has driven advances in technology that can detect them early. One of the systems being piloted internationally is the Silvanet Wildfire Sensor that “smells” fires when they’re just a smolder. Carsten Brinkschulte is the CEO of Dryad Networks, a German environmental technology company that created the sensor. He explained to The World’s Carol Hills how the technology works.
