In a US military base on the outskirts of Gainesville, Florida (USA), a team of researchers has succeeded in manufacturing an artificial lightning. To achieve thunderstorms fired a rocket that had attached a copper wire interlaced with Kevlar, a synthetic high-strength polyamide whose applications making bulletproof vests are. The result was as expected and could videotape both the image and the sound generated by the launch, in addition to recording the sound waves derived from it. <br /> <br />Dayeh Maher, of the Southwest Research Institute in San Antonio (These States) has been the instigator of the project. To carry it out, Dayeh and his team used 15 microphones located 95 meters from the shooting zone. <br /> <br />Since the highest sound waves took longer to get to these devices, scientists could create a noise map of lightning with a "stunning detail." The main conclusion from the study is that the sound caused by thunder depends directly on the strength of the electric ray, so it is intended that in future we can calculate the power of listening to the sound rays that cause. <br /> <br />Dayeh presented the results of its investigation last May 5 at a meeting of the American Geophysical Union and four Canadian geological societies, although his research for over a year's work. <br /> <br />An open door for future experiments <br /> <br />In the video you can see how, after experts fired long copper wire to a cloud thanks to a rocket, the beam generated follows the filament to the ground causing a striking green by intense heating that suffered the metal. <br /> <br />The work of these scientists open the door to other experiments that will help improve understanding of the rays. The artificially created by Dayeh down to Earth in a straight line, so that future research will be directed to getting the acoustic channel create a zigzag as those occurring naturally in nature lightning.
