estherocampo Posted May 21, 2016 Report Posted May 21, 2016 I remember those times when my mother forbidden me to go out of the house during thunderstorms wearing anything with red. She was afraid I might be hit by a lightning. Is there any scientific explanation on wearing red colors to lightning/thunderstorms? This thoughts flashed on my mind when I have read from the newspaper (Phil Star, May 17, 2016) about the 60 people from Bangladesh died due to lightning. see link:http://www.philstar.com/headlines/2016/05/18/1584433/lightning-kills-64-many-cell-phones-bangladesh Quote

Pointed conducting materials (e.g. umbrella tips) can lead to this BDV being locally exceeded, reducing the path length from cloud to ground and progressively initiating a lightning stroke. The colour of red clothing is due to light other than red being absorbed, while the red light is reflected. Since light absorption and emission plays no part in the mechanism of an electrical discharge, there is no reason to expect the colour of clothing to make any difference. sanctus 1 Quote

She probably wanted me to stay home for safety. If lightning produces some electrical discharges, can this be harnessed to produce electricity to power up some homes and other gadgets especially those areas often visited by lightning and thunderstorms? Or will it suffice the electric voltage required to power this up? Are there some studies related to this? your time to read and respond is greatly appreciated...

The energy is however released over a very short time indeed (microseconds). This leads to an enormous instantaneous power, because power is energy/time (e.g. a Watt is a Joule per second). That creates huge problems in how to capture it safely. Quote

If harnessing energy from lightning would be very difficult and would take much time, effort, and studies, then other than that, why does it exist? Quote

The article explains the problems, in order to explain why it is not done. Quote

From your link: Alam, a former head of the Bangladesh Meteorological Department, said farmers and other laborers were also carrying more metal objects such as cell phones than before. Many were also working through the storms rather than traditionally waiting until they had passed. Edited October 3, 2016 by fahrquad Quote
