Although the concentration of the ozone in the ozone layer is very small, it is vitally important to life because it absorbs biologically harmful ultraviolet (UV) radiation coming from the sun. Extremely short or vacuum UV (10â100 nm) is screened out by nitrogen.
Lightning strikes reach the ground on Earth as much as 8 million times per day or 100 times per second, according to the National Severe Storms Laboratory. Out of all the lightning strikes in the world, the United States accounts for about 20 million of the total number of lightning strikes each year. Continue Reading.
I donât know, but there is a way to get a fair estimate. Letâs find out how many volts are in a lightning strike: The bolt shows a little of the great complexity in lightning. To capture the energy, put your super-super capacitor right in the strike zone. From articles in Windpower Engineering & Development, we learn that lightning bolts carry from 5 kA to 200 kA and voltages vary from 40 kV to 120 kV.
