"Everyone has to obey the laws of physics, even if you're the King." "The power to make night into day, create life or cause death, this is all part of the mystery and magic of electricity." "Long before we knew what it was long before we harnessed it electricity was flowing through our bodies descended from the heavens." "So, there's constantly current flowing into the Earth from thunderstorms and flowing out where there's not thunderstorms" "and in that process an electric field is generated in the atmosphere." "We walk around, the voltage between your head and your toes when you walk around is two or three hundred volts, and nobody notices that because you grew up in it." "But, when there is enough of a voltage difference between the clouds and the Earth, it's hard not to notice." "One of those who was fascinated by the phenomenon was Benjamin Franklin." "Ben Franklin was a really smart guy." "He, he was one of the original experimenters with electricity, period." "He, in fact, invented the designation of positive and negative charge." "Today, high technology has replaced the kite." "In North Central Florida scientists summon lightning and bring it to the Earth with a rocket and a wire." "We can make the cloud produce lightning and direct it where we want to direct it to do tests, and that really hasn't been possible before." "They direct the lightning to strike simulated houses and power lines to understand what happens when it hits." "The rocket launch provides a more controlled experiment than anything Ben Franklin could have imagined." "Well, we do similar things." "He, he didn't think his kite was going to get struck, and he thought that if it was going to get struck that he wouldn't get hurt." "So, he was wrong there." "If the kite had been struck, he probably would have been killed, as have many people flying kites." "They load a rocket and launch it into the belly of a thundercloud." "From the rocket's tail, a spool of copper wire unwinds creating a path for the lightning to follow." "There's a level of excitement and tension before you push the button, and then there's a level of, of holding your breath for two seconds when the rocket goes up that's unlike anything else." "And, success feels real good because we, you know, we only make it happen ...twenty, twenty-five times a summer, so every one is a, is a big deal." "It's like a rocket-powered lightning rod." "Once the wire is shot up into the air the lightning hits it." "In an instant, the electric current of the bolt moves down the wire disintegrating it into a green vapor." "What flows down the lightning at fifty thousand amps is the same thing that flows in your wall at ten amps." "The temperature of a lightning bolt is more than fifty thousand degrees Fahrenheit, six times hotter than the surface of the sun." "All that heat and light is generated by uncounted numbers of electrons being forced to move." "An atom's nucleus has a positive charge." "Electrons orbiting the nucleus have a negative charge." "When electric current flows, electrons are torn from atoms and move freely." "Electricity is the flow of electrical charge, and most of the charge flows as, as electrons moving." "Whenever there's an oversupply of electrons an object develops an overall negative charge." "Nature balances things out with equal positive charges somewhere else." "The potential difference between the charges is measured in volts." "Electric current, anything from static electricity to lightning bolts, is electrons moving from negative to positive." "It seems like it's easier to make sparks and lightning than not to make them." "Anytime you have two dissimilar materials rubbing together you get sparks." "The path that leaping electrons follows depends on the material they flow through." "The human body certainly will conduct current but not a lot, not like a piece of copper." "Copper has a lot of loosely held electrons, so it's a... good conductor." "The electrons of clay and rubber are too tightly bound to their atoms to conduct electricity." "They're said to be insulators." "How electrons begin to move in the first place is a result of a force of nature called electromagnetism." "Our whole technological civilization exists because electricity can make magnetism." "And, magnetism can make electricity." "It goes back to the fact that we have two kinds of forces that are present that we call electricity or electromagnetism, and those two forces are the electric force and the magnetic force." "The fundamental charges are a positive charge and a negative charge." "To see these forces at work, head north and look up into the night sky." "Basically, the northern lights are the result of high energy electrical currents from the sun that are caught and guided by the Earth's magnetic field." "There's electricity out there." "Five, four, three, two, one." "And, we have lift-off of the Space Shuttle Columbia continuing space research through the satellite of modern technology." "On February 25th, 1996, NASA and Italian researchers made a bold attempt to harness the power in the atmosphere." "They generated electricity with a satellite and a wire." "It worked." "Let's make sure we stay that way." "Understand." "The mission was part of a new experiment of tethering satellites in space." "The experiment was based on the simple principle that when you move a conductor through a magnetic field electrons start to flow." "This generates an electrical current that can flow through a circuit." "The satellite was thrust into space using small gas jets and a thirteen mile long cable began to unreel." "And, if you put a, a wire inside of that tether you now have a moving wire that moves across a magnetic field." "...That magnetic field, in this case, is the Earth's magnetic field, and the motion is the motion of the Space Shuttle moving at very fast, high velocities, orbital speeds." "The moving wire in the Earth's magnetic field generated thirty-five hundred volts," "enough energy to power a space station." "Okay, we see the tension go way down but the tether's still going out fine, very slight lateral oscillation." "The tether was clearly visible from the ground." "It was one of the biggest manmade objects ever sent into space." "For five hours the tether swept through our planet's magnetic field generating more and more electricity." "How did they do?" "The tether has broken, and it is going away from us." "Get on the, get it on the TV, please... get it on the TV." "The tether is broken." "Copy." "Trying to photograph it floating away from us." "Looking back, we quickly saw that, in fact, the tether had broken." "This was a very, you know, it's a big shock." "It's a, it's kind of an empty feeling in, in the pit of your stomach when you look and you realize that there, there is the tether moving away from us at about eighty feet per second," "and you just wanted to reach out and grab it." "The wire was generating so much electricity that a sparkjumped from the wire to the satellite deployment system and burned through the tether." "The four hundred, forty million dollar experimental satellite just drifted away." "Yes, sir, well, those are some tether dynamics we did not want to see." "Well, look, we, we have demonstrated that you can generate a lot of electricity with tether and, unfortunately, we've also demonstrated that you can use tethers to launch a satellite into a much higher orbit." "NASA will try the experiment again because it could lead to a new, more reliable power system for space stations" "and help avoid situations like the mirror mishap." "We're moving, moving to actually is if we drive current in the opposite direction in the tether and if we could force the current to go the other way it becomes a propulsive device," "so a propellantless spacecraft." "And, the next generation of, of, of space travelers may be using electric propulsion devices as opposed to chemical propulsion devices, a little Star Trek, if you will." "Perhaps, we notice electricity most when we don't have any." "On July 13th, 1977, New York City experienced a blackout." "For twenty-five hours, New Yorkers were without lights or elevators or alarms." "Lightning had knocked out power lines north of the city, and the utility company's backup equipment malfunctioned." "It takes a lot to ...keep the electricity working, not just in machinery, but in manpower and it, it costs a lot of money to maintain these systems." "The utilities have to maintain their lines." "In the United States, 98 percent of homes and businesses receive power from a vast electrical system that is woven together with a web of power lines, a grid." "These power lines are naked live wires carrying half a million volts." "It's up to the linemen to inspect and repair every part of the grid, usually without shutting down the power." "Yeah, Bill, I was going to start making a gradual left turn and start heading over towards the line." "One of the most daring techniques is used on very high voltage tension lines." "It's pretty dangerous I feel because you're mixing aviation with, with electricity." "One, you're depending on the helicopter everything mechanical to go right." "If it goes wrong, you're going to drop out of the sky like a rock." "If the lineman makes a mistake, you're going to vaporize." "These linemen and pilots work for Agrotors Incorporated." "One of the few companies that attempts these high wire acts," "Agrotors has the best safety record in the business." "It's dangerous work that only a handful of people in the world are qualified to do." "One of them is Spider Lockhart." "Because I'm going to put the hood over top of my helmet." "The dress required for the job is a lightweight suit of armor made of stainless steel thread." "And we have a strap on the inside that ties to the pants making it an electrical connection between the pants and the jacket." "Electricity follows the path of least resistance." "In this case, the metal threads of the suit rather than flowing into the body of the worker." "We are dressed in a stainless steel suit fully conductive, fire-proof, no max, everything we have is fully conductive." "Have you ever walked through a hotel room with a certain pair of sneakers in the wintertime where you'd have, you walk up to your hotel room door and reach over and grab the door, and you get a little zap on you?" "That's called static electricity." "Basically, that's what I'm trying to eliminate from what I'm doing." "There's linemen all over the United States that are risking their lives everyday to keep the power flowing." "The dangerous marriage between helicopters and power lines is made to save money and time." "Repairs that take a conventional ground crew days," "Agrotors completes in hours." "And, Bill, we're just looking for the right structure number and then we're going to have to probably turn back a span or two once we orient ourselves." "The lineman's life depends on constant communication between him and the pilot." "This is the span that we want." "I'm going to go ahead, come down in-between the two five hundred KV lines, and we're going to find the damage location and we'll get ready to start work." "We could actually get too close ...to a power line and a tree and the electricity would spark amongst all of us, and, you know, we could actually short-out the power line and, you know, destroy ourselves." "Both men know if the communication stops something is wrong." "It's a crucial fact that Spider Lockhart learned from experience." "As soon as I felt the voltage going through me from the mechanical ground that I had," "I knew that I'd made a mistake." "Sometimes, that's a little bit late to figure out your mistakes, but I knew that as soon as I felt that." "I had enough to know that it was killing me and that's to me I was screaming to the pilot to get me away from the wire." "And, he never heard a thing because I couldn't open my mouth." "The electricity stopped Spider's heart but a coworker revived him saving his life." "And I saw Spider laying across the platform half on, half off, and I knew something was wrong." "When the helicopter came in, I didn't even wait for it to land." "I jumped up on top of it." "I started cutting his, his body harnesses off of him." "I closed his eyelids and I just starting giving him CPR." "And, I worked on him a little over three minutes before I brought him back." "When Spider is suspended in air and therefore not grounded to anything, the electricity treats him as part of the wire and safely passes over his body and not through it." "If you were able to take a voltmeter which measures voltage and measure the voltage on that helicopter, it would be energized at five hundred thousand volts and anything on that helicopter." "The metal wand gives the electricity a controlled pathway from the wire to the helicopter." "Once the pathway is established, the lineman replaces the electrical connection held by the wand with metal clamps." "The clamps allow the lineman to free his hands so that he can work." "I was working in the middle of the Everglades and I knocked the bond off, unbeknown to me, and when I went to get close to the wire, the arc went straight to my mouth." "So, I absorbed, roughly, about five hundred thousand volts to my mouth and my nose, blew all the fillings out of my mouth quarterized my nose, knocked me out of my seat belt up underneath the platform of the belly" "of the ship on the platform, and I was unconscious, it seemed like for a pretty long time, but it was just a few seconds." "The amount of voltage may be the first fact recited when explaining the dangers of electricity, but the high voltage isn't what kills a person." "It's the amps." "The electricity in the lines can flow at five hundred thousand volts but isn't necessarily deadly if the amps are low," "real low." "It only takes one amp to stop the heart." "Think of the electricity flowing through wires as the flow water." "In a squirt gun water is under pressure and moves fast, but to put out a fire, it's not the best choice." "You need a fire hose that can move a whole lot of water." "The water pressure is equivalent to voltage in electricity." "The amount of water is like electrical current and is measured in amps." "Electrical measurements are based on numbers of electrons." "A light bulb which uses one amp of current has sixteen quintillion electrons moving past a single point in the wire each second." "And, they all have to come from somewhere." "Good evening, ladies and gentlemen, my name is Bruce." "I'm going to be your guide for the tour this evening." "Behind me is Hoover Dam." "Seven hundred and twenty-six feet tall and six hundred and sixty feet thick at the base," "Hoover Dam contains enough concrete to pave a two lane road from San Francisco," "California to Miami, Florida." "Ladies and gentlemen, while you're on tour this evening, there are a few rules which you are going to have to follow." "If you hear bells, whistles, horns, sirens, or buzzes, look at me." "If I'm still standing here, it is not an emergency." "If it is an emergency, follow the instructions which I give you carefully." "Don't trample me trying to escape, I have the keys." "Hoover Dam is one of the greatest civil engineering feats in the world." "The dam is more than seven hundred feet high, forming a lake more than a hundred miles long." "Its purpose?" "To turn the energy of falling water into electrical energy." "This accomplishment was made possible by the labor of men like Tommy Nelson and Lee Tilman." "We didn't have time to think about anything too much other than we knew we were going to get paid at the end of the week." "It wasn't very much money, was it, Lee?" "No." "It was, in my case, it was five bucks a day." "Yeah, you did better than I did." "I was only making four." "Yeah, well, I was driving a truck." "Yeah, but you were driving a truck." "That's true." "Yeah." "Yeah, and so they'd give me another dollar a day, yeah." "Yeah." "Hoover Dam was built during the Great Depression of the 30's." "It not only created badly needed jobs, but was also part of a nationwide effort to transform rural life through electrification." "We went from kerosene lights to carbide lights, propane lights, and finally here comes electricity and it's available to everybody." "Rural electrification." "Franklin Delano Roosevelt, he did a great thing for the West." "Today, Hoover Dam alone generates enough electricity to serve more than a million people." "That's a lot of watts." "Multiply volts times amps and you get watts." "It takes a hundred watts to light a bulb." "A thousand watts equals one kilowatt." "Hoover Dam produces four billion kilowatts a year." "Electricity that's sent to California Nevada and Arizona." "This is the Arizona wing in the power plant." "This room is longer than two city blocks." "We have nine of our commercial generators in this wing, each producing sixteen thousand, five hundred volts of alternating current." "Each generator can supply enough electricity for a city of a hundred thousand." "The power of falling water spins the blades of a turbine." "The shaft from a turbine spins a magnet inside a tightly wound coil of wire." "This motion generates electricity." "The spinning magnet causes electrons to move in the wires and produce an electrical current." "In this case, it's alternating current." "A direct current flows directly without any pulsations." "It's just, it's just a direct current, is exactly what it is." "It's like if you open a pipeline and let the water flow in one direction." "That direct current and, and the word direct means just that, and that's exactly what it is." "Alternating current means that the electricity flows to the load and back to the generator, to the load and back to the generator and the frequency that this happens is called cycles." "The generators produce sixteen thousand, five hundred volts of electricity." "Before it leaves the power plant, the electricity's voltage is increased or boosted to two hundred, thirty thousand volts for long distance travel." "At the other end of a line, the process is reversed, and the high voltage is stepped down to one hundred ten volts and delivered into millions of homes." "In some places, the need for electrical power has forced people who can't afford it to break laws and become electricity rustlers." "In the shanty towns of Rio de Janeiro Brazilians who are unable to pay for electrical power learn how to tap into the grid for free." "I take wire from my house up to a clock or a light post and from there I bring in the electricity." "Electricity is siphoned from main lines in tangles of makeshift wiring." "Live wires and unsafe connections are hazards that the local people live with," "or in some tragic cases, die by." "It was horrible because the electrician pirate didn't survive." "He was making a connection for a lady whose house had had a blackout." "He had been underwater earlier, so he was wet." "He climbed on a zinc rooftop and started testing the wire." "He got a strong shock and was thrown from the spot and died." "These self-taught electricians are often regarded with gratitude by residents." "I am not a hero but there is risk." "I sometimes talk to people from the electric company, and they teach me how to make connections, so I don't get caught." "It can be dangerous." "Today, life without electricity is unimaginable." "Las Vegas." "Well, people are..." "like insects." "They just love light and they're drawn to it, and they want to, they want to see what it's all about." "And, so the casino operators and everybody here put a lot of light out and it just draws people in." "It just says, "We're having a party here." "Come on in." "Come on in."" "In Vegas, the theory is:" "If you build it, they will come." "And, if you build it and cover it with lights, they will come and spend money." "Without electricity this town would just be another sleepy place in the desert." "From space, it's the brightest manmade spot on the planet." "Millions of bulbs that all, at one time or another, burn out and need to be changed." "Every night, crews from the Young Electric Sign Company go to work repairing and replacing bulbs." "One of their biggest jobs is the Fremont Street Experience." "On a grid above pedestrians shine two million bulbs and a seventy million dollar light show." "The town never shuts down, but things are little slower after midnight." "That's when the crews test the system and make repairs." "It's Homer King's job to change the bulbs." "That way the computer'll tell it how bright to go." "These bulbs have a life, a life expectancy of twenty-five thousand hours." "I'm on roll tonight here." "A light bulb lights because its filament offers some resistance to the flow of electrons." "Okay, that looks better." "As the electrons try to crowd through a hair-thin tungsten wire, the energy spent overcoming resistance turns into heat." "And material that's resistive is one that requires some kind of work to push the charge across." "That means you're giving up energy that turns into heat and will heat, heat that element up." "And here, heat means light." "The filament reaches a temperature of about forty-five hundred degrees Fahrenheit." "On Fremont Street the bulbs burn bright." "Seven shows a day, seven days a week and nothing stops the display." "Except, for thunderstorms." "We'll run this color for about ten to fifteen minutes." "People ask us all the time, "Does this keep rain out?"" "Well, no, it doesn't keep rain out." "Water doesn't really hurt it." "What hurts this is lightning." "We got thirty computers on the other side of this frame, so when the lightning's there, we shut it down." "The Fremont Street lights are controlled by one hundred, twenty-one computers." "It's the largest outdoor sign in the world, towering ninety feet high and spanning almost five football fields." "Hard Rock is, this is one of my, my favorite properties here." "Not all the lights in Las Vegas rely on bulbs." "Neon and fluorescent lights use electricity to excite atoms that do the glowing, instead of heating up a thin wire." "The signs may change, but using light to attract crowds has been around since electricity was harnessed." "Coney Island was one of the very first places to use electricity." "Thomas Edison lit it up with a million of his new incandescent bulbs." "They called it an Electric Eden." "Being, I guess, in, in, like, almost like a new world." "It, it was like the playground of the world and being all lit up." "At the turn of the century," "Coney was the largest amusement park in the world." "Charles Dickens, Mark Twain, Sigmund Freud, Herman Melville, and Walt Whitman were among the thousands who flocked to see the magical electric light at work." "Coney Island wouldn't be Coney Island without electricity." "If you remember correctly, electricity made its debut in Coney Island." "Coney is lights." "Coney is movement." "Coney is electric." "The electric Astroland Cyclone is ranked one of the top five roller coasters in our country and it is one of the oldest." "By the time it reaches the bottom, it's traveling fifty-five miles an hour." "And, the passengers feel the force of 4 Gs." "For the last seventy years this electric motor has made it all possible, pulling the seven ton car to the top of the hill." "An electric motor is a generator in reverse turning electricity into motion instead of the other way around." "The motor is connected to a belt that turns a fifteen foot wheel that pulls the chain." "It's a powerful system." "When the roller coaster clanks up the hill the motor is drawing six hundred amps, enough electricity to power three modern homes." "Coney Island was one of the first places that exploited electricity for profit and pleasure." "Good use." "It's the only use." "I mean, listen, electricity it attracts us all." "If we didn't have electricity where would we be today?" "Along with the rest of New York City," "Coney Island found out what it was like to be without electricity in the blackout of 1977." "All of a sudden lights went out, and I looked up," "I looked out at the, at the park and at, up at the Wonderwheel," "nothing was moving." "As soon as scientists were able to capture electrical energy they began to experiment with it." "In 1780, an Italian anatomist," "Luigi Galvani, made groundbreaking discoveries." "Galvani made lightning measurements." "Galvani took frogs legs and showed that when, when it lightninged that they twitched." "So, he showed that the lightning radiates an electric field which produces a voltage on the frog legs." "Pull the switch." "Wait, I, I, I thought I saw a pulsation of the heart." "Doctor Blanchard, he's beginning to breathe." "You've brought this man back to life." "No, no, no, no, no, no." "The heart muscle just simply responded to a terrific electrical shock, that's all." "What was once thought to be science-fiction turned out to be fact." "A heart beats because every second electrical impulses ...spread through the heart muscle, triggering and coordinating a movement." "These signals send echoes through the body tissue to the skin where they can be detected by metal sensors and displayed as an electrocardiogram, an electrical readout that allows doctors to constantly monitor the heartbeat." "Electricity and electrical impulses are, are all over the body." "The electricity in our bodies is created by chemical reactions between cells." "What triggers the heart to squeeze are these signals, these small electrical currents which travel from the outside to the inside of the cell when, every time your heart beats." "Doctor Hugh Calkins is an electrophysiologist at Johns Hopkins University." "He uses electricity to treat and cure electrical malfunctions of the heart." "Today, he is implanting a device in a patient who suffers from a condition that causes the heart to beat too fast." "It takes a certain amount of the heart time for the heart to squeeze blood out of the heart and also for blood to get back into the heart." "So, so, if you go very, very fast instead of squeezing in a rhythmic fashion it will literally be quivering and no blood will flow in the body and within seconds you'll pass out and and in minutes after that you'll," "you'll be dead." "In order to restore the heartbeat the victim needs an electrical shock." "When you just put these on the body you get what's called a quick look that, that this acts as an antenna." "You can see what the heart rhythm is and if it's not what you want it to be if it's ventricular fibrillation, then you can go ahead and, and discharge it." "The way that's done is by pushing both of these buttons simultaneously will cause these to, to, to fire and that will give a three hundred and sixty-two volt shock across the body." "And, to the degree that the heart's in-between, the heart will be depolarized and normal rhythm will, will be restored." "In the electrophysiology lab the technology of portable defibrillators is now being implanted in the body." "Calkins threads a small wire lead downinto the heart." "And that's up in the pulmonary artery." "The wire lead acts like permanent paddles on a heart." "If the implantable defibrillator detects a problem it will automatically give an electrical shock to the heart within ten or fifteen seconds." "When I put one of these in you really have this comforting sensation that this patient's, it's like as if they're in the intensive care unit forever." "That if ever they develop a rhythm abnormality, too slow or too fast, it will take care of it and, and, and it's really this tremendous insurance policy." "Thirty-two volts." "One volt." "The most critical part of the procedure is the testing of the device." "Okay, everyone all set?" "Here we go." "The patient is given a shock that puts his heart into overdrive." "The heart starts fluttering rather than beating steadily." "Okay." "Here we go." "Ventricular fibrillation they call it, sudden cardiac death." "It's the only way to test the device." "When we are putting in the defibrillator is when we, when we induced this, this ventricular fibrillation, this very fast heart rhythm." "You saw a lot of very rapid squiggles on the screen and that was the heart beating very, very chaotically with multiple short circuits swirling around the heart, resulting in the heart beating four or five hundred beats a minute." "With ten jolts, it's about five hundred volts." "Yeah, this shows the whole readout from the heart." "We induced it with a shock, and this is the, and it takes, you can see, about eight seconds for the device to charge up and get it, get him out of the rhythm." "The trick is to customize the implantable defibrillator, so it delivers the lowest level of energy that can still get the heart beating back to its normal rhythm." "Is it all set up?" "There's more and more enthusiasm about the, the benefits of electricity." "I, I, I know for many, many years there was a lot of debate over was it better to treat patients with sudden cardiac death with medications or with defibrillators?" "And now, the studies are available showing that defibrillators are better than medications, at least the medications we have now." "So, there's a case where electricity won, where electricity was better." "This is a Utah Arm, one of the newest links between human and machine." "The device uses the body's own electrical impulses to operate and control an electrical arm." "John Miguelez works with amputees teaching them how to use and operate the myoelectric arm." "Right now there's a race between limb transplant and electronics." "We start off with a silicone skin and inside it there are electrical motors that control the opening and closing of the fingers." "Next, very often we have a electrical motor here that operates wrist rotation, supination or pronation." "Then, we also have an electrical motor over here that controls this transmission that you can see that controls flexion and extension of the elbow." "The microcomputer is mounted right here and that processes xall that information." "One of the new things about the hand is it offers a lot of pinch force over twenty-two pounds of pinch, so we need to be very careful when we're grasping things." "Bob Goodman controls his bionic arm by contracting his biceps and triceps muscles." "I like to grab my brother's hand and squeeze and kind of watch his eyes a little bit." "Maybe that's a little bit of bionic feeling." "Ironically, it was electricity that destroyed Bob Goodman's arm in the first place." "He was up on a roof removing a television antenna when something went wrong." "This antenna became top heavy and came in contact with high voltage lines in back of us, some twelve thousand, five hundred volts." "It was an aluminum ladder that I, I was on and so it became very hot and burnt my leg." "Luckily, I was knocked loose of the ladder and hit the ground because some of the doctors think well, with that amount of volts your heart probably did stop when I hit the ground it kind of jump-started my heart again." "So, I felt very fortunate when I'd learned this that I got a second chance at life even though I was missing my right arm." "When the brain sends an electrical signal to flex the arm muscle, the signal or impulse is intercepted at the muscle site by electrodes or skin sensors." "This electric impulse is then amplified and used by a microcomputer to control the electrical motors in the arm." "The patient has to be able to produce two independent signals or, or muscle contractions." "Typically with Bob in this situation we're using biceps and tricep muscles, but he has to be able to fire those independently." "If he were to fire them together, he would tell the hand to open and close at the same time which would just create a little jitter in the hand." "In my electric arm when you lock the elbow here to make the hand work, to unlock this elbow it takes the flex of both muscle sites at the same time and then an instant relaxation." "So, for me to, to get that elbow to unlock, it took quite a few months actually." "I would always flex one site before the other." "So, it was releasing the elbow is what took, took me the most time to, to get down." "So, how are things going?" "Any, you having any particular problems?" "Not really." "I put a new harness on and snugged up the fit in my socket, so it seems to be responding really well." "Great." "How's that battery doing?" "Well, I turn this on back here, and the batteries are holding up real well." "This new battery pack is lasting four to five days for me." "All right." "Okay." "It's opening and closing the same, the amount of effort for both." "Look at this and clean this." "Okay." "Open and close." "Good." "Close." "Great." "When I first tried it on," "I think there was a hint of having an electrical arm this close to my body, but as soon as I was able to make the arm work and the hand to, to work and, that all disappeared." "I thought it was so neat that, that a person could make a, a life-like hand work so effortlessly that, that that fright left right away." "It was, it became more of an enhancement than a threat right away." "It's been releasing real well." "Each arm can cost anywhere from forty-five thousand dollars up to a hundred and twenty thousand dollars." "I've chosen to wear this arm everyday, so maybe I didn't learn quite enough lesson from an electrical shock because I still wear an electrical arm." "Okay." "All right." "Good for another ten thousand miles." "Yeah." "Great." "The modern world would be inconceivable without electricity." "In eight hours a man used to hard work and continuously exert one-tenth of a horsepower, but the same amount of work can be done by an electrical motor in a fraction of the time." "Electricity as a harnessed power has no rival." "It is clean, silent and can be turned on and off instantly." "Worldwide there are still two billion people who exist without electrical power." "Most are located in remote places like the Brazilian village of Boa Sorche." "Too isolated to receive power from the country's grid, the residents live without the electrical inventions of the 20th Century and without conveniences like medical vaccines that need refrigeration electric motors or clean running water." "The villagers use contaminated surface water which was funneled from the springs to the local watering hole." "The only clean water was buried deep beneath the Earth." "An electrical pump was needed to get the water to the surface." "To solve this problem the governments of Brazil and the U.S. Joined forces to provide electricity by harnessing the sun's energy." "Putting up power poles and lines is so expensive that actually photovoltaic energy is much cheaper here ...than using traditional forms of fuel." "Photovoltaic cells or solar panels convert energy radiated by the sun into electricity." "Clean, renewable power that villages like this can afford." "Engineer, Roger Taylor, is part of the electrification initiative in Brazil." "In this particular village they're going to change by having the school accessible at night." "The health clinic will certainly be able to store vaccines and provide more immediate health services." "And, the water pumping system here, particularly since it's so deep, will provide very pure or very clean filtered water." "The joint effort will set up four different systems here." "The largest will power an electric water pump for the well." "Water pumping takes a fair amount of energy in this case because the well is fairly deep, the well here." "We will put the pump at about a hundred meters down in the ground, so it takes a lot of energy to pump that water up, up to the top." "When a solar panel is put out into the sun, the materials within it release electrons and produce electricity." "In Boa Sorche the panels are being connected to a pump." "When the system is up and running, the electric current and water will flow." "On May 26th, 1997, the village turned on the power." "Technological advancements that took a hundred years to develop arrived here with the flick of a switch." "And, so now it will be very interesting to see once they have the basic standard of living that many people in the rest of the world enjoy" "how their lives and their culture will evolve from that." "More and more aspects of our world depend on electrons in motion." "They flow through countless switches and machines." "They flow through our bodies and brains." "They can even start life." "So, in a test tube you can make life-like things, molecules, with electric sparks." "When researchers and stockmen had cloned a sheep named Dolly a tiny spark of electricity was used to fuse cells and start the egg growing into an embryo." "All this started with a curious fellow back in 1752." "That was when a man with a key and a kite stepped out into a storm." "He snatched lightning from the heavens and introduced electricity to mankind."
