Artificial Lighting Feasibility

Sunlight is 100,000 lumens per square meter. High Intensity Discharge lamps like xenon lamps produce 3300 lumen at 36 watts of power use. Thus, to replicate sunlight it will take 30 lamps using 1100 watts total per sqr m. However, the sunlight dims as it travels across the sky, at around 8 am and 4 pm, sunlight is just 50% brightness or 50,000 lumens or 15 lamps using 550 watts per sqr m. Thus, across an 8 hour day, the energy requirement would be 550 watt x 8 hours + (550 watts x 8 /2) or 6600 watts-hrs. Thus, artificially lengthening the growing period of a plant by 100% (8 hours of daylight) would require 6.6 kW-hrs per day.

Thus, a crop plant that takes 4 months to mature can be ready in 2 months or 60 days with artificial lighting during the night. The cost would be 6.6 kW-hr per day x 60 days or 396 kW-hr per sqr m. or US$39.6 at US$0.1 per kW-hr. Using a 43 kilos of tomatoes per sqr m per year as basis or 14.3 kilos per 4 months on standard day hydroponic growing, production stands to double to 14.3 kilos every 2 months at value of US$5.72. However, the added power cost of US$39.6 for the period is prohibitive to tomato growing. Thus, for Urban Farming applications, standard hydroponics is much more profitable.

Accidents and Small Loans

Most people experience financial downfalls in spite of a steady paycheck or income. This is because most income is given in a regular cycle. However, life does not work in regular cycles but rather in sudden, often unforeseen, events. These events can catch an individual at times when cash is low, often in between pay cycles. Such events, although common, can be not as costly as some might expect. A broken tail light on a car and/or an accidental sports injury often require only a small amount to remedy, easily covered by the next paycheck. However, these types of damage and injury often cannot wait.

Also, traditional bank loans can take a long time to process and usually not available for the amounts in question. Thus, most people resort to a  Payday loan of some sort. Fortunately, there are lending institutions out there that offer these small scale loans that tide people over until the next payday. They charge interest of course, but the convenience they offer more that compensates for it.

The Good and the Bad

People can fall into such financial difficulties that can force them to acquire loans with unscrupulous people. These loans often have uncontrolled interest rates and non-payment can lead to a world of problems. Thus, people tend to pay more than they bargained for when engaging in such loans. People don’t deserve to live in fear like this, specially people who have legitimate jobs that just fell into hard times. Fortunately, there are people and institutions that give people the Cash Advances. These loans can help people pay off such “bad” loans and start a new life.

Thus, people can rest assured that there is this form of protection or social service available to them. People need to pay for loan interests but at least this is just money out of the pocket and not a world of pain and fear. Anyway, people with such “bad” loans also need to pay interest so the two loans are relatively comparable and the “good” loan is definitely very much safer.

The Emotional Side of Money

As Pete and Eleanor’s story so vividly shows, talking about money can allow you to build the life you want. In fact, we believe that financial security begins with a conversation—whether between spouses, between a parent and a child, or between an adult and an aging parent.
But these conversations aren’t easy, especially in the beginning. Most of us are used to chatting casually about the stock market or mortgage rates, but when it comes to candid, personal conversations about how much money we’ll need for retirement or how we’ll possibly be able to pay for our children’s college educations, the talk is much tougher. In a wealthy country where millions of investors have money in the stock market, there is still a desperate shortage of honest, candid talk about how we should be planning for the future.
And unfortunately, as Pete and Eleanor’s story also points out, not communicating about financial matters, from spending to investing to planning for the future, is an almost surefire way to undermine a relationship. So why, despite the obvious payoff and the equally obvious price of avoidance, do most people neither initiate nor participate in these essential family conversations about money? Because money is never just money, especially in the context of a family. For starters, money is tied up with our deepest emotional needs (such as security, comfort, success, and confidence) and fears (such as failure, inadequacy, and poverty) as well as with our sense of self- worth and identity. And ultimately, it becomes a reflection of our relationships. “In the first part of our marriage, there were all these inequalities, and money was a huge unspoken one,” says Pete. “Now it’s more of an equal playing field.”
Like it or not, even your parents’ attitudes about money have likely influenced yours. If your father or mother always tried to save that little bit, you may have adopted the same fiscally restrained habits. Or like a pendulum, you may do the opposite now that you’re an adult, refusing to let those money-saving tactics run your life. Either way, you’re reacting to lessons learned at your parents’ knees.
For example, I have a friend whose father used to drive her crazy with his penny-pinching habits: He phoned her only after five P.M. (he had one of those old-fashioned phone plans where the rates dropped at night), and he parked his car in a lot a mile away from where he was going if he could save a dollar. In response, as a young girl, my friend would call her dad whenever the urge struck, even if it was a mere ten minutes before the rates changed, partially to prove that her actions weren’t being dictated by the chance to save a buck. Valuing time and convenience more than economy, she often took cabs instead of buses and paid a housekeeper for cleaning she could easily have done herself. Figuring that you only go around once, she routinely indulged in expensive wine and topnotch restaurants. Only lately, many years later, has she come to recognize how much all those indulgences compromised her ability to save for her future and the things that mattered more.
My colleague Tom’s financial baggage also stems from his upbringing. Despite a steady income, his parents sometimes ran short of cash. Since Tom consistently held jobs as a kid—doing a paper route or umpiring Little League games—he usually had some cash on hand. “As a twelve- or thirteen-year-old, I was proud to always have a few hundred bucks,” he recalls. “I remember my dad and mom borrowing from me a few times to buy groceries or go out to a movie. In those pre-ATM days, I was like their bank for short-term credit.” Not surprisingly, this situation made Tom quite resentful in the long run, Thirty years later those emotions continue to affect how he deals with finances and money-related communication, but not in a positive way. Even today Tom never talks to his parents about their Financial position since it brings back uneasy memories. He and his wife don’t talk very much about their financial decisions or long-term p]ans either. While Tom attributes a lot of this silence to juggling two careers and raising two children, he also admits that his early negative money associations may play a part in his current attitude.

Starting the Conversation

When Pete, a longtime colleague of ours, married his wife, Eleanor, in 1973, it would have been safe to assume that she, being a banker, would handle the finances while he, then a schoolteacher, would take a backseat. Then their son was born with a disability and the couple decided that Eleanor should quit her job and stay home with him. Once Pete, who had returned to graduate school and obtained his MBA, became the only breadwinner, he also inherited the financial-decision-maker role. At the same time Pete—a generous, jovial, and articulate man— turned into quite the spender, thinking nothing of buying an expensive suit that he’d wear only two or three times. To compensate for his champagne taste in clothes, Eleanor, when she shopped at all, would do so at discount stores (a detail she kept from Pete, who would have been horrified). Sure, her husband’s income had shot up, but so had his appetite for luxuries, including high-priced cars.
“We moved to California from New York, and I saw everyone driving around in BMWs,” explains Pete with a self-deprecating laugh and the kind of regret that only hindsight can bring. “1 thought that must be the state car, so I went out and bought one.” Over the next fifteen years he bought another and another and another, just as soon as the mileage on the “old” car passed twenty thousand—or a newer model captured his fancy. Despite hefty sports-car price tags, he never thought to consult his wife about those—or any other— purchases.
That attitude, combined with an overall lack of communication, almost cost Pete his marriage. Since the couple never discussed money, let alone a savings or an investment strategy Pete never knew how increasingly resentful his highly educated wife, who had spent ten years in the banking industr)c was becoming about her lack of participation in the Family Finances or Pete’s spending decisions.
Pete and Eleanor may have avoided facing their issues, but they couldn’t escape the downfall of their marriage. After a separation of several months, the couple decided that divorce was inevitable, and together they headed to a financial planner to figure out how to split their assets.
But unlike so many similar stories, this one has a happy ending. “You guys obviously care about and love each other,” the financial planner observed one afternoon after numerous joint meetings. “What are you doing getting a divorce?” Thus prompted, Pete and Eleanor asked themselves the same question and subsequently decided to try to work out their differences. After months of marriage counseling and a lot of hard work, Pete and Eleanor learned how to communicate with each other about money and everything else. They identified what was important to them as individuals and as a couple.
The upshot? At forty-seven, Pete quit his job to devote himself full time to the nonprofit international health-related causes about which he’s passionate. Investments they’ve made together now Finance their lifestyle, one in which they agree on each and every sizable purchase as a team. “Though I’m ashamed of my past behavior, I’m also proud of our courage to stick it out,” says Pete. “It’s so much easier to walk away from very difficult issues than to confront them head-on, I am the better—and we are the stronger—for it.”
Pete and Eleanor’s new financial policies and procedures, along with their.ongoing discussions about values and priorities, led to their recently building a dream house in Sun Valley, Idaho. “In almost thirty years of marriage, this is the first major purchasing decision we ever made together,” admits Pete.
In short, Pete and Eleanor now make a point of dealing with their life together—and their money—as equal partners. Once every three months they meet with their financial advisor to review their finances and make (or revise) their money decisions for the next six months. Then they go out to a nice restaurant and discuss their decisions and plans. What better way to reaffirm your love for each other than to talk about the life you’re living now and your dreams for the future?

WHO IS THE ANIMAL

A San Francisco science fair recently awarded a prize to a junior high school student whose science project consisted of cutting the head off a live frog with a pair of scissors, to find out whether frogs swim better with or without their brains.
Of course, this is not the only case of frogs being treated cruelly in our schools. They are often dissected by children ostensibly learning “how life works.” But what did this youngster learn through his experiment? I think he learned that it is all right to treat other living things as if they have no feelings, as if they are nothing but machines. I think he learned disrespect for life. And I wouldn’t call that a good thing.
The science fair judges, however, obviously disagree with me, for they commended the boy on his contributions to the forward march of science, predicted great things for his future, and rewarded him for scientifically proving that: “Frogs will not swim with brain missing unless harassed. A frog swims better with head on.”3
The attitude we develop towards animals as children tends to stay with us through the rest of our lives. And it continues to influence our experience, not only of animals, but of other people, ourselves, and life itself. There is a great deal of evidence from all over the world indicating that people who have, as children, learned to care for animals, grow up more capable of caring for themselves, and for other people. By the same token, people who later become criminals have very often abused animals as children. We find high statistical correlations in every country and culture where research has been done.
The way we treat animals is indicative of the way we treat our fellow humans. One Soviet study, published in Ogonyok, found that over 87% of a group of violent criminals had, as children, burned, hanged, or stabbed domestic animals.4 In our own country, a major study by Dr. Stephen Kellert of Yale University found that children who abuse animals have a much higher likelihood of becoming violent criminals.5
Studies of inmates in a number of U.S. prisons reveal that almost none of the convicts had a pet as a child. None of them had this opportunity to learn to respect and care for another creature’s life, and to feel valuable in so doing.
But these attitudes can be reversed, even in criminals. Heartwarming research has been done in which convicts nearing their release dates were allowed to have pet cats in their cells with them. The result? “Of the men who loved and cared for their cats, not a single one later failed as a free man to adjust to society.6 This in a penal system where over 70% of released convicts are expected to return to jail.
The attitudes towards animals shown by the youngster at the science fair, and by the Soviet criminals when they were youths, are not at all unusual. We’ve all grown up in a system that condones such cruelty. Our public stance is basically that animals are ours to treat any way we wish, and that kindness to animals and sensitivity to them as fellow beings is an option some may choose if they want to, but it is no more incumbent upon us than being nice to plastic dolls.

THE MOST SELFLESS ANIMAL IN THE WORLD

If the little Scottish terrier whose monument still stands in Edinburgh is not the most selfless animal who ever lived, a dolphin named Pelorus Jack might well be. For many years, this dolphin guided ships through French Pass, a channel through the D’Urville Islands off New Zealand. This dangerous channel is so fill of rocks, and has such extremely strong currents, that it has been the site of literally hundreds of shipwrecks. But none occurred when Pelorus Jack was at work. There is no telling how many lives he saved.
He was first seen by human beings when he appeared in front of a schooner from Boston named “Brindle,” just as the ship was approaching French Pass. When the members of the crew saw the dolphin bobbing up and down in front of the ship, they wanted to kill him—but, fortunately, the captain’s wife was able to talk them out of it. To their amazement, the dolphin then proceeded to guide the ship through the narrow channel. And for years thereafter, he safely guided almost every ship that came by. So regular and reliable was the dolphin that when ships reached the entrance to French Pass they would look for him, and if he was not visible, they would wait for him to appear to guide them safely through the treacherous rocks and currents. On one sad occasion, a dmnken passenger aboard a ship named the “Penguin” took out a gun and shot at Pelorus Jack. The crew was furious, and when they saw Jack swim away with blood pouring from his body they came very close to lynching the passenger. The “Penguin” had to negotiate the channel without Pelorus Jack’s help, as did the other ships that came through in the next few weeks. But one day the dolphin reappeared, apparently recovered from his wound. He had evidently forgiven the human species, because he once again proceeded to guide ship after ship through the channel. When the “Penguin” showed up again, however, the dolphin immediately disappeared.
For a number of years thereafter, Pelorus Jack continued to escort ships through French Pass—but never the “Penguin,” and the crew of that ship never saw the dolphin again. Ironically, the “Penguin” was later wrecked, and a large number of passengers and crew were drowned, as it sailed—unguided—through French Pass.

All Creatures Have Place in the Choir

You will not find very many monuments to dogs in this world. But in Edinburgh, Scotland, in a public area known as Greyfriar Square, there stands a statue, erected by the local citizens, in honor of a little terrier named Bobby.
Why did the townspeople erect this statue? Because this little dog taught them a lesson in the years he lived with them—a most important lesson. Bobby the Scottish terrier had no owner. And as often happens to smalltown dogs with no master, he was kicked around by just about everybody, and had to scrounge through garbage to get anything to eat. Not what you would call an ideal life, even for a dog.
But it happened that there was in the village a dying old man, named Jock. In his last days, the old man noticed the plight of the sorry little dog. There wasn’t much he could do, but he did buy the little fellow a meal one evening at the local restaurant. Nothing fancy, just some scraps. But it would be hard for anyone to over-estimate the extent of little Bobby’s gratitude.
Shortly thereafter, Jock died. When the mourners carried his body to the grave, the terrier followed them. The gravediggers ordered him away, and when he refused to leave they kicked him and threw rocks at him. But still the dog stood his ground, and would not leave no matter what they did. From then on, for no less than fourteen years, little Bobby honored the memory of the man who had been kind to him. Day and night, through harsh winter storms and hot summer days, he stood by the grave. The only time he ever left the gravesite was for a brief trip each afternoon back to the restaurant in which he had met Jock, in hopes of scavenging something to eat. Whatever he got he would solemnly carry back to the grave, and eat there. The first winter Bobby had almost no shelter, huddling underneath tombstones when the snow was deep. By the next winter, the townspeople were so touched by his brave and lonely vigil that they erected a small shelter for him. And fourteen years later, when little Bobby died, they buried him where he lay—alongside the man whose last gesture of kindness he had honored with such devotion.

WHERE DID THE WEB COME FROM?

Appropriately enough, the idea for the Web came from scientists—just as had the original idea for the Internet.
In 1989 Tim Bemers-Lee, a physicist at the European Particle Physics Laboratory (CERN), proposed the concept of the Web as a system for transferring ideas and research among scientists in the high- energy-physics community.
Berners-Lee’s original proposal defined a very simple implementation that used hypertext but did not include multimedia capabilities. Something very much like this was introduced on Steve Jobs’s NeXT computer system in 1990. The NeXT implementation allowed users to create, edit, view, and transmit hypertext documents over the Internet. The system was demonstrated for CERN committees and attendees at the Hypertext ‘91 conference.
In 1992 CERN began publicizing the World Wide Web (WWW) project and encouraging the development of Web servers at laboratories and academic institutions around the world. At the same time, CERN promoted the development of WWW clients (browsers) for a range of computer systems including X Windows (Unix), the Apple Macintosh, and PC/Windows. (Today, the two most popular and useful of these browsers are Netscape Communicate and Micorosfi Internet Explorer—both of which are available via free download on the Internet.)

WHAT IN THE WORLD IS THE WORD WIDE WEB?

The most popular aspect of the Internet is, of course, the World Wide Web. The “Web”—as it is familiarly called—provides access to virtually all those computers (servers) on the Internet that offer hypermediabased information and documentation.
Hypermedia is a technology that presents and relates information by using nonlinear, nonsequential links rather than linear sequences. (Less formally put, hypermedia and hypertext enable users to navigate both the World Wide Web and the documents on it with point-and-click ease. To navigate, one “clicks” on words, phrases, and icons in a document, which provide links that enable you to jump at will to a new location in the document, or even to a new document altogether.) In short, the Web is a uniquely intuitive and information-rich environment.
Additionally, the Web is hospitable to graphic images, photographs, audio, and even full-motion video. Thus the Web has a multimedia capability that is of great value to scientists and those interested in science. Astronomers can view full-color space images on-line. Oceanographers can access real-time “remote sensor” data from key oceanographic sites around the world 24 hours a day. Students of chaos theory on the East Coast can connect and watch fractal trees generate on a minicomputer in Los Angeles. And paleontologists can get audio and image clips of Stephen Jay Gould giving a series of lectures at Harvard.
An additional perk of Web technology is that the Web provides easy tools for inexpensive on-line publication. Combining global connectivity and individual empowerment, the Web enables anyone who has a computer and the proper Internet connection to become a multimedia publisher. With the right tools (most of them available as free downloads from sits highlighted in this book) and a little effort, you can easily translate scientific papers into electronic Web documents (also known as “pages” or “sites”) that the entire world can access. The same goes for reports. calls for papers, conference proceedings, announcements, course catalogs, etc. For more on this see the section later in this chapter entitled “A Few Web Fundamentals/ General Web Resources.”
