NASA's terrifying visualization of atmospheric aerosols
Heatwaves, hurricanes and other extreme weather might be the "face of climate change," but it's not the only sign. A grim new visualization from NASA shows another problem caused indirectly by global warming: airborne particles and droplets. These "aerosols," shown on a single day on August 23rd, come from dust, volcanic ash and other sources. They're particularly brutal this year because of fires in California, British Columbia and the southern part of Africa.
Watch an unmanned helicopter put out fires with help from a drone
Fighting wildfires is sometimes a daunting prospect with manned aircraft; pilots can't always fly around the clock or cover every patch of land. They won't have to if Lockheed Martin's efforts pan out. It recently demonstrated a tweaked version of its unmanned K-MAX helicopter that can work in tandem with a quadrotor drone, Indago, to stamp out fires with relatively little human intervention. As you'll see in the clip below, Indago serves as a forward scout that marks any hotspots. After that, K-MAX swoops in with a bucket to douse the flames. It fetches more water on its own, too.
MIT gurus dream up self-sustaining sensor network for preventing forest fires
Thanks, MIT. Why don't you just make the rest of the world feel a little more useless. Every week or so, we're forced to stare at yet another amazing invention coming from your doors; to be frank, it's just downright unfair. All childish angst aside, the latest idea to come from the institution is one that could certainly be put to good use: a self-sustaining sensor network that taps into trees for power in order to continuously monitor forests for threats of fire. Moreover, the concept could be applied in other scenarios as well -- to detect potential threats such as smuggled contraband along a nation's borders, perhaps. Testing of the wireless sensor network (developed by the appropriately named Voltree Power) is scheduled to begin next spring, and we're hearing that pot-sniffing turtles may even be brought in to create a completely natural self-policing environment.[Via Inhabitat]
