Children who eat less salt consume fewer sugar- sweetened soft drinks and may significantly lower their risks for obesity, elevated blood pressure and later- in- life heart attack and stroke, according to a study in Hypertension: Journal of the American Heart Association from February 2008.

How can you reduce the amount of salt in your kids' diet? Dr. Sanjay Gupta, CNN chief medical correspondent: It' s really important to reduce the amount of sodium because it does make a difference. These researchers said that cutting kid' s salt intake by half - - that' s about three grams - - has the effect of reducing soda intake by two soft drinks per week.

Let me give you some examples of how to do that: Staying away from fast food such as pizza, hamburgers and hot dogs is a good idea because these foods are high in sodium. A fast- food hamburger contains about 750 to 800 milligrams of sodium, or about half of what a young child should get on a daily basis, and that' s just one sandwich. Keep them in moderation and certainly don' t sprinkle any more salt on them. There are also lots of low- sodium alternatives to products that tend to contain a lot of salt - - soup and cheese, for example. Fresh fruits and vegetables are always a good way of getting nutrition without salt.

What' s the deal with salt? Gupta: Study author Dr. Graham Mac. Gregor said that salt isn' t really used as a preservative any more, and the amount of salt contained in processed foods is much higher than we need in our diets.

Is soda bad for you? Gupta: Soda is associated with a number of health issues.

For each additional drink per day, a child is 1. 6 times more likely to develop obesity later in life. Studies have also suggested a link between soda and osteoporosis.

( CNN) - - As the rescue capsule brought each Chilean miner to the surface, they sprang from obscurity into the global spotlight - - a type of attention that they never sought. The 33 miners, who had been stuck for nearly 70 days inside a mine near Copiapo, Chile, will likely feel the crush of media requests and offers from book publishers, movie and television producers.

They will probably be peppered with questions from family, friends, neighbors, strangers and reporters. When ordinary people are thrust into the spotlight, it can be disorienting and stressful.

How they handle that attention could progress or hinder their recovery, experts said. Mario Sepulveda, the second miner extracted, said he hoped to maintain a low- key profile. & quot; The only thing I ask, personally, is that you please not treat us like celebrities or journalists. I want to continue being treated like Mario Antonio Sepulveda Espinace, the worker, the miner. I love that, and I think that in some shape, way or form I want to continue working, & quot; he said.

In his book & quot; The Frenzy of Renown: Fame and Its History, & quot; Leo Braudy writes about the effect of sudden fame for unintentional newsmakers. & quot; It' s a great problem for regular people, who are subjected to intense publicity and focus, & quot; said Braudy. Sometimes, it' s ordinary people who' ve done something heroic or rescued someone. & quot; They' re lionized; and for some of them, it destroyed them, & quot; he said, referring to a incident in which a paramedic who rescued baby Jessica Mc. Clure from a Texas well took his life years later.

But everyone responds differently, he said. It could be complicated for the miners to re- enter society and find normalcy in their lives when there' s so much global curiosity. Viewers tuned in around the world to watch their rescue. Ramon Sabella survived a 1972 plane crash in the Andes Mountain. He and his fellow survivors' story inspired the book and movie & quot; Alive. & quot; After his rescue, so intense was the attention from reporters and photographers who followed Sabella that he found cameras in his hospital bathroom.

His advice to the Chilean miners: Spend time with family and friends and try not to be overwhelmed. & quot; Remember, it' s going to be a limited time span. It may be weeks, but then go back to real life. There' s going to be attention, media scrutiny, books, movies - - that' s not normal life, & quot; he said. & quot; Don' t live exclusively for that [ attention] . Tell your story, but live your life. & quot; The publicity could have benefits and harm, said Dr.

John Markowitz, a research psychiatrist at the New York State Psychiatric Institute. & quot; To the extent that publicity made the survivors feel like heroes and cared for by the outside world, it could be supportive, & quot; he said. & quot; We know that social support protects against psychopathology for trauma victims. & quot; & quot; On the other hand, if the survivors felt exploited, intruded upon and then discarded by the media, I imagine that the effect of media coverage could be negative. & quot; After a life- threatening event, people who feel supported are less likely to get , Markowitz said. The fact that the miners survived as a group is a mental health benefit, he said. & quot; One thing is solidarity, & quot; Markowitz said. & quot; They' re not in this alone. They have this kind of social support. & quot; About 8 percent of people who have been through a traumatic event are likely to get PTSD, said Dr.

Katherine Muller, director of psychology training and a clinical psychologist at Montefiore Medical Center in New York. Workers would have to be monitored for PTSD symptoms such as avoidance, nightmares and re- experiences of the trauma, she said. & quot; From my perspective, people who talk about the experience, think about it and discuss it, tend to do better and don' t end up with PTSD. & quot; After a traumatic incident, it' s important to resume day- to- day life, spend time with family and friends and get some normalcy back, she said. It might be difficult to get back to normal as the miners will probably & quot; to be treated for a while like movie stars, & quot; Braudy said. One of the downsides is that the miners may be inundated with requests and pulled in many directions. & quot; That' s a downside, & quot; he said. & quot; People confuse fame with money, fame with richness - - and they want a piece of you. & quot; The point is not to add stress to the miners by prying, said Tyler Cowen, author of & quot; What Price Fame. & quot; & quot; These people didn' t ask to be put in that position, & quot; he said. & quot; There is some right to privacy that might end up not being respected. It' s not like they are performers, who go on stage and deal with reviews.

These people are victims. & quot; CNN' s Mariano Castillo contributed to this report.

( CNN) - - Here' s yet another reason to stay in shape: Thinner people contribute less to global warming, according to a new study. Researchers at the London School of Hygiene and Tropical Medicine published a study showing that, because of food production and transportation factors, a population of heavier people contributes more harmful gases to the planet than a population of thin people.

Given that it takes more energy to move heavier people, transportation of heavier people requires more fuel, which creates more greenhouse gas emissions, the authors write. & quot; The main message is staying thin. It' s good for you, and it' s good for the planet, & quot; said Phil Edwards, senior lecturer at the London School of Hygiene and Tropical Medicine. The study offers this novel approach to the global warming problem as U. S. lawmakers discuss the future of climate change legislation.

This week, the the House Energy and Commerce Committee is scheduled to begin on a comprehensive energy and climate bill. On Friday, the Environmental Protection Agency announced that six greenhouse gases pose potential health hazards, an announcement that could prompt the regulation of the gases.

More than 1 billion adults worldwide are overweight, and about 300 million are , the study said. Generally, the body mass index, a measure of obesity, is increasing in most countries worldwide, from China to European countries to the United States.

BMI is going up because of the availability of food and motorized transportation, Edwards said. People are less active now than they were 30 years ago, and the prevalence of fast food has given people less healthy, more energy- dense options. Using statistical models, the authors compared the distribution of BMI in the United Kingdom in the 1970s - - when 3. 5 percent of the population was obese - - with a prediction for the country' s BMI distribution in 2010, reflecting 40 percent obesity. & quot; In terms of environmental impact, the lean population has a much smaller carbon footprint, & quot; Edwards said.

The population with 40 percent obese people requires 19 percent more food energy for its total energy expenditure than the population with 3. 5 percent obese people, the study showed.

This 19 percent increase in food consumption translates into an increase of 270 million metric tons of greenhouse gas emissions, the study said. & quot; The findings make sense and highlight an important global co- benefit of losing weight, along with the significant personal health benefits, & quot; said Patrick Kinney, associate professor at Columbia University' s Mailman School of Public Health, who was not involved in the study. In terms of obesity rate, the U. S. population is not far off from the overweight population model in this study. The country has 33. 3 percent obese people, according to the Mayo Clinic.

The study suggests that governments have a responsibility to encourage people to be more physically active, Edwards said. Active transportation, such as cycling and walking, helps maintain a healthy weight but requires safe streets, he said. & quot; If the government wants to promote active transport, which would be good for the environment and for individual health, it needs to make the environment safe to do that, & quot; he said. Although has come into the forefront as a major world problem recently, this is not the first time scholars have thought about the connection between fossil fuel and body fat. In 1978, a year the United States experienced an oil shock, a study in the American Journal of Public Health showed that if all overweight people in the country aged 18 to 79 reached their optimal weight, the resulting energy savings would equal 1. 3 billion gallons of gasoline.

After the dieting period, about 750 million gallons of gasoline would be saved every year, said the authors, Bruce Hannon, professor at the University of Illinois, Urbana- Champaign, and Timothy Lohman, now professor emeritus at the University of Arizona. Today, research has shown that the obesity epidemic costs the United States about $ 100 billion a year, said Dr. Martin Donohoe of Portland State University, who runs the Web site Public Health and Social Justice. In terms of energy expenditure, the average food product travels 1, 500 miles to get to your table, he said.

Some measures to curb obesity include making healthier meals available in schools, putting nutritional information on food packages and menus, and banning trans fats, he said. All About & bull;

( CNN Student News) - - November 24, 2009 & # 8226; & # 8226; & # 8226; Transcript THIS IS A RUSH TRANSCRIPT. THIS COPY MAY NOT BE IN ITS FINAL FORM AND MAY BE UPDATED. CARL AZUZ, CNN STUDENT NEWS ANCHOR: In our last show before we break for Thanksgiving, we are talking about shopping safety, friendly food farmers and a treacherous trek for a turkey. I' m Carl Azuz, and this is CNN Student News!

First Up: Philippines Abduction AZUZ: First up, an election for regional governor leads to shocking violence in the Philippines.

Ismael & quot; Toto& quot; Mangudadatu planned to run for governor of Mindanao, a region in the southern part of the country. He' d been threatened with kidnapping if he filed his nomination papers, so he sent his wife and sisters to do it. He thought women might have better protection.

They were part of a group of about 40 people that army officials say was kidnapped by a hundred gunmen who killed at least 21 of them, including Mangudadatu' s wife and one of his sisters. The Philippines' government called the attack & quot; a gruesome massacre of civilians. & quot; The country' s military is working to track down the people who did it.

Home Sales Increase AZUZ: In the United States, some hopeful signs in the housing market.

Sales of existing homes - - homes that were already built, not brand new ones - - jumped more than 10 percent last month. The number is now at its highest point in more than two- and- a- half years. Experts think the increase might be because of a tax credit that' s available to first- time home buyers, and some economists have warned that this spike may only be temporary.

But the jump in sales is one of the reasons why the stock market did well yesterday.

The Dow Jones average closed at its highest level in more than a year. Spacewalk AZUZ: 18 hours, 27 minutes. That' s how long NASA astronauts on a mission to the international space station spent outside of it. The crew wrapped up its third and final space walk yesterday.

This one lasted a little less than six hours.

The shuttle is scheduled to be back on the ground on Friday, and one of these guys will get to meet his new baby daughter, who was born after his mission took off last week. Shoutout MATT CHERRY, CNN STUDENT NEWS: Today' s Shoutout goes out to Mr. Allensworth' s social studies classes at Concord High School in Concord, North Carolina!

In the business world, what color is associated with making a profit? If you think you know it, shout it out!

Is it: A) Red, B) Black, C) Blue or D) Green? You' ve got three seconds - - GO!

When a business is & quot; in the black, & quot; it means that it' s making a profit. That' s your answer and that' s your Shoutout! AZUZ: Okay, the day after Thanksgiving, referred to as Black Friday because it' s when retailers expect to start making a profit. If you' ve ever braved a mall on Black Friday, you know the crowds can be huge.

Susan Candiotti looks at what' s being done to keep shoppers safe. SUSAN CANDIOTTI, CNN CORRESPONDENT: The mad dash for bargains can be funny to watch, but last Thanksgiving weekend in New York, it was horrific. A Long Island Wal- Mart security guard was trampled to death in a stampede on Black Friday, arguably the biggest shopping day of the year.

EMMANUEL MOULTRIE, BLACK FRIDAY SHOPPER: People screaming, people coming in the store, passing out, falling out. It was a horrible site.

CANDIOTTI: Emmanuel Moultrie took us back to that Wal- Mart. He says when the doors opened at 5: 00 a. m. , an hour later than expected, the crowd surged forward, glass shattered and guard Jimmy Demoura was caught in a human steamroller. MOULTRIE: I mean, you had at least seven to eight people on top of each other.

You didn' t even see him.

And it was on top of him, and they were stuck because they were squished, compacted in there. CANDIOTTI: Moultrie says he felt like he was swept up in a tidal wave, trapped against a vending machine. MOULTRIE: I said I will not hit that ground. If I hit that ground, it would have been, I couldn' t even get my arms from my side. CANDIOTTI: Wal- Mart avoided criminal prosecution by agreeing, among other things, to improve crowd control at all New York stores.

The giant retailer says it' s also voluntarily instituting changes nationwide this week. Wal- Mart declined a CNN interview. Instead, the company provided a pre- taped statement that said sports and entertainment crowd control experts gave them help.

DAPHNE MOORE, SPOKESPERSON, WAL- MART: We' re committed to looking for ways to make our stores even safer for our customers and our associates this holiday season. CANDIOTTI: Changes may include snaking lines outside and inside stores - - similar to airport checkpoints - - and scattering sales items. Some stores will remain open 24 hours starting Thanksgiving Day through the weekend, so when Black Friday sales start at 5: 00 a. m. , shoppers can already be inside, possibly avoiding chaos.

For shoppers up before dawn for door- buster deals at any retailer, this safety advice from police: JOHN TIMONEY, CHIEF, MIAMI POLICE DEPARTMENT: If you see pushing and shoving, arguing for no valid reason, you know you have a potential problem right there. And if that' s the case, I walk to the end of the line, let them all go in. CANDIOTTI: Emmanuel Moultrie, who received a settlement from Wal- Mart, says he won' t be burned again. MOULTRIE: If you reach to a store and you see that' s not, that that behavior' s not being demonstrated, you need to leave, fast. Leave fast.

CANDIOTTI: As part of this agreement with prosecutors, Wal- Mart paid nearly $ 2 million to a victim' s fund and a community grant. OSHA cited the retailer for exposing its employees to danger when it should have known better. Wal- Mart says in a statement safety is always a top priority.

Susan Candiotti, CNN, New York. Word to the Wise TOMEKA JONES, CNN STUDENT NEWS: A Word to the Wise. . .

BMI ( noun) This stands for body mass index, which is a way of estimating a person' s body fat based on height and weight AZUZ: At Lincoln University in Pennsylvania, any student with a BMI over 30 has to pass a fitness class in order to graduate.

And about 80 seniors only have 1 semester left. To pass, you just have to show up and participate; you don' t have to actually lower your BMI. But some students say the policy discriminates against them, and that they came to college to learn, not be lectured about their health.

Officials at the private school say they' re trying to help students stay healthy and avoid medical problems later in life. Blog Report AZUZ: We figured you might wanna talk about this. Our blog at CNNStudent. News. com is the place to go! You had a lot to say about another subject there: Should the government consider a tax on sugary drinks?

Michael says & quot; sure. It' ll help fight obesity and give more money to our government to help the cause. & quot; But Chris argues soda, candy and sugary items in general aren' t the cause of obesity. & quot; It' s the person' s lifestyle that causes it. & quot; Yevgeniy writes, & quot; It' ll help the government because some people will still buy soda with or without the tax, and it' ll bring in a lot of money. & quot; But Devinne says, & quot; It might bring in money, but the government gets enough from other things, and people don' t need to pay even more for soda at a time when money is scarce. & quot; John says, & quot; It' d just add more trouble for middle- and low- income families, anger the public, and hurt stores. & quot; From our quick poll on that blog: 35 percent of you' d call a national tax helpful. Almost half say it' d be harmful. 17 percent have mixed feelings.

AZUZ: Well, Thanksgiving is just a couple days away.

A lot of families have their own traditions around the holiday, whether it' s what they eat or how they celebrate.

Out in Colorado, some farmers have started their own tradition of giving, one that' s earned the thanks of thousands of local residents. Ana Cabrera of affiliate KMGH fields the details.

UNIDENTIFIED FEMALE: Opening the farm up to the community is a beautiful gift to the community. CHRIS MILLER, FARM OWNER: We were brought up, you know, what goes around comes around. ANA CABRERA, KMGH REPORTER: If that' s the case, Chris Miller has a lot of good coming her way. MILLER: We got wiped out with hail in the last part of July, so there' s not as much stuff left, but people still need food.

CABRERA: And hundreds seized the opportunity to gather fresh food for free: potatoes, carrots, even brussel sprouts. UNIDENTIFIED FEMALE: Fresh vegetables; we make a lot of soup. CABRERA: For the second year in a row, the Millers opened their farm, a way to give back to the community in tough times. MILLER: We asked the people to come out who were really in need of the food.

CABRERA: People like Steve Rivera. STEVE RIVERA, RECIPIENT: Past couple of years, actually, have been real bad. I' ve been laid off several times from different jobs. CABRERA: Rivera brought his family to pluck and pack barrels full of potatoes to take home. RIVERA: Some of this stuff, you know, is in really good shape.

CABRERA: And not just for themselves. RIVERA: As big as theses potatoes are, I' m not going to keep that much. CABRERA: Rivera plans to pass this gift on to others. RIVERA: I will probably help at least six families that I know of.

Whoever needs it, you know, I' ll have it there and I' ll say if you need it, take it. So, it doesn' t go to waste. CABRERA: From the Millers to the Riveras, it' s the spirit of giving, turning soon- to- be empty fields into full bellies. Cross Country Race AZUZ: No doubt, it' s a great story. But not every tradition is heart- warming.

In fact, this one seems down right cold!

That is what contestants expect in Iowa' s annual Living History Farms Off- Road Race, which kinda seems like a fancy title for a jog through the woods. A lot of the 7, 000 people who took part showed up in costume. Because for some reason, wearing silly clothes always helps you run better. First place prize: a frozen turkey!

Second through fifth, they just get a chicken. Goodbye AZUZ: But it seems like the whole race is for the birds ( turkey gobbles) . All right, I was going to do that sound myself; my producer nixed it. But either way, it gobbles up all our time for today.

We hope you have a very happy Thanksgiving. CNN Student News returns on Monday. We' re looking forward to seeing you then. Meantime, thanks for being such a great audience.

Take care.

( CNN) - - The U. Coast Guard, champion of boating safety everywhere, is to blame for a tragic 2009 accident that killed an 8- year- old boy during a holiday boat parade in San Diego Bay, a federal safety board said Tuesday.

The National Transportation Safety Board said the Coast Guard crew' s excessive speed caused the crash between the crew' s 33- foot patrol boat and a 24- foot Sea Ray. The crash killed the child, Anthony De. Weese, and seriously injured four of 12 others on the recreational boat. At the time, the patrol boat was responding to a reported grounding, which the NTSB called a non- emergency.

It was cruising at least 19 knots, or roughly 22 miles per hour - - far in excess of the 8 knots prudent for the conditions, the NTSB said. & quot; The Coast Guard is an organization that traditionally fills the role of rescuer, & quot; NTSB Chairman Deborah A. Hersman said. & quot; It is especially sad that a family night of celebration in the Bay ended in tragedy because of a coxswain' s poor judgment and the Coast Guard' s ineffective oversight of vessel operations. & quot; The Coast Guard said Tuesday the NTSB' s findings aligned with its own investigation, and that it has taken steps to prevent similar accidents. & quot; We owe it to the De. Weese family, the memory of Anthony, and the public we serve, to learn all we can from this tragic accident, & quot; said Coast Guard spokesman Lt.

Cmdr. Christopher O' Neil. & quot; We take very seriously our role as the nation' s maritime safety agency and we' re profoundly saddened by the loss of life in an accident involving one of our crews. & quot; The collision occurred at night, during a holiday event known as the Parade of Lights. The patrol boat struck the Sea Ray from behind, according to the NTSB. None of the Coast Guard crew was injured.

Three of the five crewmembers on the Coast Guard boat, including the operator, refused to be interviewed by NTSB investigators, the NTSB said. The NSTB said the Coast Guard' s lack of oversight of its small boat vessel operations contributed to the accident. The Coast Guard' s San Diego station lacked an effective oversight system to monitor vessels on patrol, it said. And the station' s officer of the day, who was on the boat, did not advise the coxswain to slow down. The NTSB called the speed excessive given the prevailing darkness, background lighting and heavy boat traffic in the area.

Four Coast Guardsmen on the patrol boat were court martialed or faced non- judicial punishment. In March, the coxswain was found guilty of dereliction of duty for failure to perform a risk assessment, and was sentenced to three months confinement and reduced in rank. A petty officer 2nd class pleaded guilty to dereliction of duty and was reduced in rank. In January, another petty officer received a letter of reprimand. The case of one crewman charged with dereliction of duty was dismissed because of insufficient evidence at a non- judicial hearing.

A fifth Coast Guardsman who was on the boat as a trainee was not charged. The Coast Guard said that as a result of a review of boat accidents, it has made changes to improve its operations, including increased navigation training requirements for boat crews. It also is ensuring that stations have the most suitable boats to carry out local missions. The Coast Guard said in the past five years, during 2.

6 million boat hours, there have been three Coast Guard boat- related accidents resulting in fatalities. In addition to the San Diego collision, a Coast Guard member was killed in March 2007 after being ejected from a patrol boat near Seattle. Another Coast Guardsman died in October 2010, during a training mission in Virginia after he fell into the water while transferring between a small patrol boat and a cutter.

( CNN) - - From Detroit to Denmark, the power of the pedal is generating electricity and energy conservation awareness.

At a homeless center in Michigan, residents work out on 10 specially outfitted bicycles that send power back into the building. Female inmates at an Arizona jail take turns on a stationary bike to power their TV to watch their favorite soap operas.

And this week, an upscale Copenhagen hotel began offering free dinners to guests who sweat it out on power- generating cycles.

The use of human muscle generates mere fractions of the power required to run these facilities. But the sparks of energy are also inspiring environmental consciousness, say green fitness enthusiasts. A 30- minute workout creates about 50 watts, which is enough electricity to run a laptop for one hour or a phone charger for six full charges or one energy- efficient light bulb for 2. 5 hours, according to Re.

Rev, a company that retrofits gym equipment to capture human power. & quot; It' s not going to solve world' s energy problems, & quot; said Hudson Harr, the company' s president. & quot; We' re quick to dispel that it' s a major utility contribution. It connects with people and it teaches people about energy. & quot; It' s not likely to cut down the power bill for big sports complexes. Gyms have huge treadmills, flat screens, heating and air conditioning, and often require lots of energy. & quot; The impact [ of human powered exercise machines] is diluted by the massive consumption of the facilities themselves, & quot; Harr said.

The modified exercise equipments take kinetic energy from a person' s workout and converts it into a form of electricity.

This gives people more motivation to work harder, Harr said. & quot; The average user wants to up the resistance and test the limits and see how much they can send back, & quot; Harr said. But this concept of human- powered exercise equipment has not become mainstream. The idea is there, but implementation is going slowly, said Adam Boesel, the owner of a human- powered gym in Portland, Oregon. & quot; Nobody is coming out with the Prius of exercise equipment, & quot; he said. & quot; I think it' s because big companies move slow. I liken it to the hybrid car.

Five years ago, there were only a couple electric cars, now everyone wants to do it. & quot; All the elliptical trainers and bicycles at his Green Microgym convert human energy. The human and solar power at the gym generated 36 percent of its electricity, saving about 37, 000 kilowatt- hours in 2009, Boesel said. The average annual electricity consumption for a U.

S. residential utility customer is about 11, 000 kilowatt- hours. & quot; The way we look at it, you can waste energy or not waste energy, & quot; Boesel said. & quot; Anytime people exercise, that exercise is being wasted in terms of heat.

We' re trying to save a little bit of energy. & quot; The human- powered exercise equipments have not taken hold in the fitness market, but people are interested, said Bruce Bruckbee, a green consultant for hotels and sports recreation centers. & quot; People feel as though they' re doing something good.

They' re making good use of all the energy they' re creating themselves and having a small impact on carbon footprint. What I think is most important is it creates a personal awareness, & quot; said Bruckbee, managing partner for Leisure Green.

At the Cass Community Social Services in Detroit, the residents who are homeless, in transitional or temporary housing, never expressed any interest in environmental issues before. & quot; Homeless people don' t care about polar bears, & quot; said the Rev. Faith Fowler, the organization' s executive director. & quot; They care about jobs and health. & quot; But this year, the center introduced 10 stationary bikes ( purchased through a donor) that send power back into the building. Residents became hooked. They started asking, & quot; Can we start a garden and can we start composting? & quot; Ninia Cobb, a 43- year- old resident, said the bikes give her two goals: to lose weight and to give back energy. & quot; I' m not going to light up a whole building by myself, & quot; she said. & quot; I feel like I' m helping the energy thing when you ride it.

It feels good. & quot; The bikes attracted local cycling enthusiasts and youth groups into the center too. & quot; They care about the planet, but they didn' t care about the homeless, & quot; Fowler said. & quot; They' re sitting shoulder- to- shoulder to someone who has been homeless for two to three years, they sit and talk, and they' re both acting as problem solvers. & quot; But not everyone implemented electricity- generating bicycles for environmental reasons. The Maricopa County Sheriff' s Office in Arizona purchased a stationary bike that generates 12 volts of electricity to power a 19- inch television in the jail. Sheriff Joe Arpaio wanted the inmates to exercise. The bicycle will not save the county any money in terms of power bills, but it' s making the inmates exercise every day. & quot; It' s caught on, & quot; Arpaio said. & quot; The inmates seem to like it.

The public, from what I got back, thinks it' s a great idea. I don' t know why no one' s thought of it before. & quot;
