The first image shows lightning counted in bins of 0.005 degree latitude by 0.005 degree longitude. It takes a specific amount of energy to vaporise sand into gas. That would actually bring ur calculation to somethin like 2.7 x 10^4 or something. https://www.nationalgeographic.com/environment/natural-disasters/lightning.html, electrical discharge caused by imbalances. Do you always think big?
So if we divide the power draw for the house into the power of a lightning bolt, we’ll have the number of houses that bolt can power: N = 2.7 x 106 Wh per bolt / 4.8 x 104 Wh/house. There are approximately 2,000 thunderstorms at any given moment
worldwide. Even the most knowledgeable first responders may not recognize a lightning-related injury, let alone particulars, which a medical examiner, police investigator or on the rare occasion a trained lightning expert may have difficulty identifying to record accurately. So if we take some averages, say, 100 kA and 100 kV, this bolt would carry this much power, P: Recall that 1010 Watts is 10,000,000,000 or 10 billion Watts. Although it’s a good idea to use the energy of lightning bolts, but the major problem is the harvesting method. Site Map | Privacy Policy | RSS, BP charts sustainable energy scenarios to 2050 in recent Reuters Events webinar, Pedernales Electric Cooperative signs 100-MW PPA on Texas wind project, Maryland, North Carolina, Virginia collaborate to support offshore wind development, bp Wind Energy chooses Power Factors software for North American wind fleet. This is called "hot lightning" and it is the cause of lightning fires according to Uman. homes, what protection is their from premium-prioed surge protectors ?
on Applied Climatology, 379-80. In a direct strike, the electrical currents in the flash channel passes directly through the victim. These methods have a large range of errors: not calculating the length of the lightning strike correctly, or getting the amount of gas heated per length wrong, or the temperature, or voltage, or number of electrons – all give pretty large errors for these calculations. They’re easy to find – since glass isn’t something you want in commercial sand, the mine filters them out. There is elecromagnetic energy all around us. 10,000,000,000__is 10 giga__.
Mulitiple directionalble kites could spread the collection area out both vertically and horizontally. Human sensory acuity is not as fine as that of the milliseconds duration of a lightning flash, and our ability to observe this event is subject to the brain's inability to comprehend it. Cloud-to-ground lightning bolts are a common phenomenon—about 100 strike Earth’s surface every single second—yet their power is extraordinary. These strikes reverse the charge flow of typical lightning bolts and are far stronger and more destructive. A volt is a measurement of the amount of energy released as each pack of electrons flows from one side of an object to another – for instance, a battery. The class of these products are often called a "finial" or "air terminal". In the comic book world, it’s an ingredient in the formula for developing superpowers.
But I have to think there are more than a few people who have considered the problem. (2014). Lightning interferes with AM (amplitude modulation) radio signals much more than FM (frequency modulation) signals, providing an easy way to gauge local lightning strike intensity. Danyar: To you question, yes, 10 Berry Biga-watts. To keep a 100-watt light bulb going for one second, one hundred joules of energy will be used. Measuring the energy in lightning is a way of measuring potential damage: A lightning strike can vaporise rock, so what might it do to wood or electronics? One estimate is that the annual global death toll is 6,000.[11]. Cloud-to-ground lightning bolts are a common phenomenonâabout 100 strike Earthâs surface every single secondâyet their power is extraordinary. A capacitor is a device used to store charge. The energy of an average 3 mile-long lightning strike is one billion to ten billion joules. Evidence of lightning strikes includes erratic magnetic fields.[22][23].
Florida’s unique geology provided an interesting route to answering this question. Lightning Current. If you search Wikipedia for “Harvesting Lightning Energy” there is a discussion there that is fairly accurate, I think. –Paul Dvorak.
To capture the energy, put your super-super capacitor right in the strike zone. Lightning is incredibly powerful. Lightning is known, as a standard, to have a voltage potential of 100million volts. Hey Paul or anyone else out there – I need help. NOAA online says 22 million cloud-to-ground strikes per year. You are absolutely right in that capturing a bolt or even part of it requires a mystifying method. The following data is from an Atlanta Journal article. This ignores the reality that lightning, as the first event, may assume responsibility for the overall and resulting accident. Some types of lightning, including the most common types, never leave the clouds but travel between differently charged areas within or between clouds. [27] To do so, one should tune a standard AM medium wave receiver to a frequency with no transmitting stations, and listen for crackles amongst the static. Thanks to all of you for the comments. 10,000,000,000,000 is 10 DOOM watts, by the way . If you could sum (integrate) the current generated by that voltage, you could calculate the charge transferred in the lightning strike. Although lightning bolt is dangerous, we can conclude, it does not carry much energy. Such systems are designed to detect the conditions which are believed to favor lightning strikes and provide a warning to those in the vicinity to allow them to take appropriate cover. So the power is: 1010 W-sec. Preprints, 11th Conf. Blast injuries – being thrown and suffering. There are tens of thousands of towers already erected (from existing high voltage power towers to cell phone towers) that could be potentially retofiited with a system that collects the energy of lightning. Telephones, modems, computers and other electronic devices can be damaged by lightning, as harmful overcurrent can reach them through the phone jack, Ethernet cable, or electricity outlet. Most if not all utilities also have an additional fixed charge (pays for the poles, wires, transformers, breakers, power plants, employee wages, etc.) Direct strike – the person is part of a flash channel. [1][2] Lightning strikes the average commercial aircraft at least once a year, but modern engineering and design means this is rarely a problem. Our measurements show that the biggest lightning strikes are multiples of the average lightning strikes: A big one might be 20 times as large as the average. So the answer to the original question is that a big bolt could power a small, 56-house town for a day. At one site, we collected several hundred fulgurites; more than 250 lay in the field, with many more found in spoil piles, filtered out of the sand prior to its being loaded onto trucks. With several such detectors in an area, you could model the location as well as the charge associated with the strike. Sometimes the sand was deposited 15 million years ago, sometimes 5 million years ago. You might fly a kite in an electrical storm with a wire attached to the capacitor and the other lead to ground.
At any rate if we actually started to develope this technology it would most likely be at a slow enough pace for us to to be able ask and answer those questions long before they become crises events.
If the damage is severe, the tree may not be able to recover, and decay sets in, eventually killing the tree. 10,000,000 (watts, volts, or anything) is 10 mega__.
Depending on the flash strength and access to medical services, it may be instantaneously fatal or cause permanent injury and impairment. Now why might this be at all interesting or useful?
Actually, the electrical charge is transferred in a few milliseconds (thousandths of seconds). Thanks a lot for the calculation. © 1996-2015 National Geographic Society, © 2015- The average cost in the USA for a residential service is around $0.10 per kWh, so the average bill is around $100-$200 per month for energy. i think there is a way you can collect it and use it at the same time but i am stil think about it but i this i have a idea about it if you wil like to know just ask. These sand mines probably have about one million year’s worth of fulgurites buried inside of them. Video footage - A Beech tree (Fagus sylvatica) that has been hit by lightning. Lightning is an electrical discharge caused by imbalances between storm clouds and the ground, or within the clouds themselves.
