how much power is in a lightning strike


There’s sand, and there’s limestone.

Is there a way the lightning could just be attracted away from these dangerous strikes – something like a lightning beacon? Also, given the very low probability lightning will strike the same point repeatedly and consistently, scientific inquiry is difficult even in the areas of high CG frequency. With one billion joules, the light bulb will be lit for 116 days. As such it is often inconclusive, albeit highly probably a lightning flash was involved, hence categorizing it as a "lightning incident" covers all bases.
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. Not much else, and all of it is young, geologically speaking. In lightning damage claims, it is important to determine if the loss was, in fact, caused by lightning instead of being a simple mechanical breakdown. Although a single strike of lightning does last a mili-second many lightning discharges have multiple discharges called dart leaders. All events associated or suspected of causing damage are called "lightning incidents" due to four important factors. is it possible to store lightning energy in a large capacitor?? Cloud-to-ground lightning bolts are a common phenomenon—about 100 strike Earth’s surface every single second—yet their power is extraordinary.

2011 June 8: A lightning strike sent 77 Air Force cadets to the hospital when it struck in the middle of a training camp at Camp Shelby, Mississippi. Could there be another route to calculating lightning energy that might pare down some of these errors?

In 1987 an Atlas-Centaur rocket was struck by lightning on launch and had to be destroyed.

Enormous quantities of energy pass through the body very quickly, resulting in internal burns, organ damage, explosions of flesh and bone, and nervous system damage.

Ball lightning, a small, charged sphere that floats, glows, and bounces along oblivious to the laws of gravity or physics, still puzzles scientists.

Would it be difficult to recreate the natural process of creating lightning in a lab?

Based on that principle, magnetic links are widely used for the measurement of the lightning currents. 10,000,000,000__is 10 giga__. Do you always think big?

If you could sum (integrate) the current generated by that voltage, you could calculate the charge transferred in the lightning strike. The thicker ones had to be formed by much more energetic lightning bolts: a thicker fulgurite means more sand had to be vaporised. [16][17], In Kisii in western Kenya, some 30 people die each year from lightning strikes. The near-instantaneous rate of discharge causes a potential (difference) over distance, which may amount to several thousand volts per linear foot. Most fulgurites we recovered were short fragments, though the longest ones found were a yard or two long.

Flavor Text: Sometimes you don't need to strike the same place twice Finish Style: Anodized Multicolored Finish Catalog: 51 Added: 14 August 2013 Creator: Valve Update: The Arms Deal That way it could collect more positive ions from the storm cloud. National Geographic Almanac of Geography (2005), "What happens when lightning strikes an airplane? Lightning is incredibly powerful. Hundreds more survive strikes but suffer from a variety of lasting symptoms, including memory loss, dizziness, weakness, numbness, and other life-altering ailments. Cars are havens from lightning—but not for the reason that most believe.

The discovery and implementation of Benjamin Franklin’s lightning rod tamed this once formidable, divine weapon. About 240,000 incidents regarding lightning strikes happen globally each year. 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.
There are approximately 2,000 thunderstorms at any given moment worldwide. 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.

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. Most CG flashes only "strike" one physical location, referred to as a "termination". I don’t want to discourage anyone from trying to perfect this technology.

At this temperature, the sand melts.

Direct strike – the person is part of a flash channel.

Air’s dielectric breakdown limit is 3.0 million volts per meter. If we know the duration of this strike, we can then calculate the energy. 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.

Video footage - A Beech tree (Fagus sylvatica) that has been hit by lightning. For most of human history, people have been terrified by lightning. Florida is the most dangerous state with 14 killed and 27 injured in 1990. According to Uman, the German scientist Pockels discovered that basalt rock in the vicinity of lightning strikes was magnetized and deduced currents on the order of 10,000 amps in 1897. Actually, the electrical charge is transferred in a few milliseconds (thousandths of seconds). Most homes in the USA use around 1,000kWh to 2,000kWh per month – that is, about 33 to 66 kWh per day (1kWh = 1,000 Watt-hours). Using the top of the tower as a mast for high flying (Ben Franklin) kites could get that conductor much higher into the storm clouds.

Either way, i think a lighting bolt only has enough energy to power on 1 single lighting bulb, for 3 or 4 months.

Replace 120kv with 100million volts.

Power is energy per time, and our measurements of fulgurites suggest that megajoules of energy make rock in thousandths to millionths of seconds.

A less common type of strike, called ground-to-cloud (GC) lightning, is upward propagating lightning initiated from a tall grounded object and reaching into the clouds.

I picked 100,000V to work with because it’s a round number. Cherington, J. et al. –Paul Dvorak.

Blast injuries – being thrown and suffering. Browse the most current issue of Windpower Engineering & Development and back issues in an easy to use high quality format. To capture the energy, put your super-super capacitor right in the strike zone. In reality, it was an early form of a heavy duty surge protection device (SPD). This is important as lightning can strike without rain actually falling. Lightning detection systems are coming online, both satellite and land based, however their accuracy is still measured in the hundreds to thousands of feet, rarely allowing them to pinpoint the exact location of the termination.

When the spacing between them increases, the voltage needed to produce lightning increases.

https://en.wikipedia.org/w/index.php?title=Lightning_strike&oldid=986194208, Creative Commons Attribution-ShareAlike License. A bolt is around 20,000°C (about 35,000°F). About 69% of all lightning events worldwide are strikes between the atmosphere and earth-bound objects. is it possible to store lightning energy in a large capacitor?? Some types of lightning, including the most common types, never leave the clouds but travel between differently charged areas within or between clouds. Lightning generates temperatures hotter than the surface of the sun, in excess of 20,000 degrees Celsius, a temperature that is otherwise unrelateable to the human experience.

The largest fulgurite found during recovery at the sand mine. It is difficult to convert high voltage power to the lower-voltage electricity that can be stored. Then, if that voltage was stored into a capacitor to multiply the voltage, what would it be? Chaff and silver iodide crystal concepts were devised to deal directly with the cloud cells and were dispensed directly into the clouds from an overflying aircraft.

The electric field under a storm allows the bolt to penetrate through more air than normal.

I have experimented with high voltage my entire life.

Other rare forms can be sparked by extreme forest fires, volcanic eruptions, and snowstorms. There is elecromagnetic energy all around us. Thanks a lot for the calculation. 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. Although it is not impossible!

So let’s assume one house needs 2,000 Watts/hour to keep the frig, furnace, computer, and all things plugged in going. A single lightning event is a "flash", which is a complex, multi-stage process, some parts of which are not fully understood.

Sometimes the sand was deposited 15 million years ago, sometimes 5 million years ago. Lightning is known, as a standard, to have a voltage potential of 100million volts.

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. The point is not to force a violent discharge but to collect the energy from the system befoere it happens.

Most lightning protection devices and systems protect physical structures on the earth, aircraft in flight being the notable exception. [citation needed]. Hallucinations may be induced in people located within 200 meters of a severe lightning storm.

Stronger or nearby lightning strikes will also cause cracking if the receiver is tuned to a station. If you search Wikipedia for “Harvesting Lightning Energy” there is a discussion there that is fairly accurate, I think. Lightning has killed 6,000 persons in the United States in the past 34 years.

Mulitiple directionalble kites could spread the collection area out both vertically and horizontally. thanks. This is called "hot lightning" and it is the cause of lightning fires according to Uman.

When the lowermost step comes within 150 feet (46 meters) of a positively charged object, it is met by a climbing surge of positive electricity, called a streamer, which can rise up through a building, a tree, or even a person.

I was told that a 1.5 Vdc AA battery contains 15 joules of energy and can produce 300 volts after charging a disposable camera flash capacitor.

The fulgurites range in thickness from about the size of a baby’s little finger to about the size of man’s arm in thickness.

Nonetheless, it was fun to “run the numbers.” –Paul Dvorak. Most commonly, the lightning current ceases in about a millisecond for a given stroke, but sometimes there is a continuing current on the order of 100 amps following one or more of the strokes. Currents over 200,000 amps have been reported. Hi paul, That would actually bring ur calculation to somethin like 2.7 x 10^4 or something. Although lightning bolt is dangerous, we can conclude, it does not carry much energy.

[10], Annual fatality tolls vary greatly. Lightning is not only spectacular, it’s dangerous.

> If 10,000,000 watts is Ten Mega-watts, does that make 10,000,000,000 watts Ten “Biga-watts”? Let’s find out how many volts are in a lightning strike: The bolt shows a little of the great complexity in lightning. The other two plots show the results of a resolution of half as much or twice as much.

Sound travels at the slower speed of about 340 m/s (depending on the temperature), so the flash of lightning is seen before thunder is heard. –Paul Dvorak. These individual discharges are called strokes. Strikes can cause cardiac arrest and severe burns, but 9 of every 10 people survive.

http://www.agu.org. They’re easy to find – since glass isn’t something you want in commercial sand, the mine filters them out.
