Love Story

"The Lost Wallet"

As I walked home one freezing day, I stumbled on a wallet someone had lost in the street. I picked it up and looked inside to find some identification so I could call the owner. But the wallet contained only three dollars and a crumpled letter that looked as if it had been in there for years. The envelope was worn and the only thing that was legible on it was the return address. I started to open the letter, hoping to find some clue. Then I saw the dateline–1924. The letter had been written almost sixty years ago. It was written in a beautiful feminine handwriting on powder blue stationery with a little flower in the left-hand corner. It was a "Dear John" letter that told the recipient, whose name appeared to be Michael, that the writer could not see him any more because her mother forbade it. Even so, she wrote that she would always love him. It was signed, Hannah. It was a beautiful letter, but there was no way except for the name Michael, that the owner could be identified. Maybe if I called information, the operator could find a phone listing for the address on the envelope. Operator," I began, "this is an unusual request. I'm trying to find the owner of a wallet that I found. Is there anyway you can tell me if there is a phone number for an address that was on an envelope in the wallet?" She suggested I speak with her supervisor, who hesitated for a moment then said, "Well, there is a phone listing at that address, but I can't give you the number." She said, as a courtesy, she would call that number, explain my story and would ask them if they wanted her to connect me. I waited a few minutes and then she was back on the line. "I have a party who will speak with you." I asked the woman on the other end of the line if she knew anyone by the name of Hannah. She gasped, "Oh! We bought this house from a family who had a daughter named Hannah. But that was 30 years ago!" "Would you know where that family could be located now?" I asked. "I remember that Hannah had to place her mother in a nursing home some years ago," the woman said. "Maybe if you got in touch with them they might be able to track down the daughter." She gave me the name of the nursing home and I called the number. They told me the old lady had passed away some years ago but they did have a phone number for where they thought the daughter might be living. I thanked them and phoned. The woman who answered explained that Hannah herself was now living in a nursing home. This whole thing was stupid, I thought to myself. Why was I making such a big deal over finding the owner of a wallet that had only three dollars and a letter that was almost 60 years old? Nevertheless, I called the nursing home in which Hannah was supposed to be living and the man who answered the phone told me, "Yes, Hannah is staying with us. " Even though it was already 10 p.m., I asked if I could come by to see her. "Well," he said hesitatingly, "if you want to take a chance, she might be in the day room watching television." I thanked him and drove over to the nursing home. The night nurse and a guard greeted me at the door. We went up to the third floor of the large building. In the day room, the nurse introduced me to Hannah. She was a sweet, silver-haired old timer with a warm smile and a twinkle in her eye. I told her about finding the wallet and showed her the letter. The second she saw the powder blue envelope with that little flower on the left, she took a deep breath and said, "Young man, this letter was the last contact I ever had with Michael." She looked away for a moment deep in thought and then said Softly, "I loved him very much. But I was only 16 at the time and my mother felt I was too young. Oh, he was so handsome. He looked like Sean Connery, the actor." "Yes," she continued. "Michael Goldstein was a wonderful person. If you should find him, tell him I think of him often. And," she hesitated for a moment, almost biting her lip, "tell him I still love him. You know," she said smiling as tears began to well up in her eyes, "I never did marry. I guess no one ever matched up to Michael…" I thanked Hannah and said goodbye. I took the elevator to the first floor and as I stood by the door, the guard there asked, "Was the old lady able to help you?" I told him she had given me a lead. "At least I have a last name. But I think I'll let it go for a while. I spent almost the whole day trying to find the owner of this wallet." I had taken out the wallet, which was a simple brown leather case with red lacing on the side. When the guard saw it, he said, "Hey, wait a minute! That's Mr. Goldstein's wallet. I'd know it anywhere with that bright red lacing. He's always losing that wallet. I must have found it in the halls at least three times." "Who's Mr. Goldstein?" I asked as my hand began to shake. "He's one of the old timers on the 8th floor. That's Mike Goldstein's wallet for sure. He must have lost it on one of his walks." I thanked the guard and quickly ran back to the nurse's office. I told her what the guard had said. We went back to the elevator and got on. I prayed that Mr. Goldstein would be up. On the eighth floor, the floor nurse said, "I think he's still in the day room. He likes to read at night. He's a darling old man." We went to the only room that had any lights on and there was a man reading a book. The nurse went over to him and asked if he had lost his wallet. Mr. Goldstein looked up with surprise, put his hand in his back pocket and said, "Oh, it is missing!" "This kind gentleman found a wallet and we wondered if it could be yours?" I handed Mr. Goldstein the wallet and the second he saw it, he smiled with relief and said, "Yes, that's it! It must have dropped out of my pocket this afternoon. I want to give you a reward." "No, thank you," I said. "But I have to tell you something. I read the letter in the hope of finding out who owned the wallet." The smile on his face suddenly disappeared. "You read that letter?" "Not only did I read it, I think I know where Hannah is." He suddenly grew pale. "Hannah? You know where she is? How is she? Is she still as pretty as she was? Please, please tell me," he begged. "She's fine…just as pretty as when you knew her." I said softly. The old man smiled with anticipation and asked, "Could you tell me where she is? I want to call her tomorrow." He grabbed my hand and said, "You know something, mister, I was so in love with that girl that when that letter came, my life literally ended. I never married. I guess I've always loved her. " "Mr. Goldstein," I said, "Come with me." We took the elevator down to the third floor. The hallways were darkened and only one or two little night-lights lit our way to the day room where Hannah was sitting alone watching the television. The nurse walked over to her. "Hannah," she said softly, pointing to Michael, who was waiting with me in the doorway. "Do you know this man?" She adjusted her glasses, looked for a moment, but didn't say a word. Michael said softly, almost in a whisper, "Hannah, it's Michael. Do you remember me?" She gasped, "Michael! I don't believe it! Michael! It's you! My Michael!" He walked slowly towards her and they embraced. The nurse and I left with tears streaming down our faces. "See," I said. "See how the Good Lord works! If it's meant to be, it will be." About three weeks later I got a call at my office from the nursing home. "Can you break away on Sunday to attend a wedding? Michael and Hannah are going to tie the knot!" It was a beautiful wedding with all the people at the nursing home dressed up to join in the celebration. Hannah wore a light beige dress and looked beautiful. Michael wore a dark blue suit and stood tall. They made me their best man. The hospital gave them their own room and if you ever wanted to see a 76-year-old bride and a 79-year-old groom acting like two teenagers, you had to see this couple. A perfect ending for a love affair that had lasted nearly 60 years. - Anonymous —

India’s Massive Blackout Calls for Smarter Grid, From the Bottom Up

A 600-million-person blackout lays
out the severity and scope of India's
grid challenges. Microgrids and solar
power could help.
JEFF ST. JOHN: JULY 31, 2012
The only good thing about India's
daily blackouts is that when there's a
truly massive power outage, people
are prepared for it.
Thus, when the power went out
across eight northern Indian states
early Monday morning, leaving some
370 million people in the dark, most
of the critical facilities -- Delhi's
international airport, hospitals and
police stations, large-scale commercial
and industrial power users and
higher-end homes and apartments --
were ready to go with backup
generators.
But everyday people were stuck with
no light, no heat, and no public
transportation. Traffic jams snarled
thoroughfares without traffic lights,
rail commuters were stuck in stalled
electric trains, and small businesses
had to close.
Then, on Tuesday, things got worse,
with a 20-state blackout that cut
power for anywhere between 620
million and 680 million people --
about half of India's population, or
twice the number of people now
living in the United States. This time
around, some hospitals lost power,
and coal miners were trapped by
stalled equipment. Only about 40
percent of power was back up by mid-
afternoon.
And while Monday's outage was tied
to demand outstripping supply, the
government was still "absolutely
clueless why this has happened
again," Shakti Sinha, principal
secretary in the power department of
the Delhi government, told The
Washington Post of Tuesday's
outage. Power Minister Sushil Kumar
Shinde blamed the new crisis on
states taking more than their allotted
share of electricity, and other officials
said grid faults were likely to blame,
but didn't know where they were or
how many may have occurred.
India's Grid in Dire Need of Repair
Could smart grid technologies help
solve the problems that caused these
blackouts? We'll have to wait for the
official inquiry to come up with what
went wrong before we can start
answering that question -- though it's
likely that more grid monitors and
sensors could make that fault
detection task easier.
Beyond that, however, there's a world
of work to do. India's grid is a mess,
with money-losing economics, daily
power outages, and technical and
non-technical power losses (i.e.,
inefficiency and theft) that add up to
20 percent to 50 percent of all power
generated, compared to the United
States' (almost all technical) losses of
7 percent or so.
Like the United States and China,
more than half of India's power
comes from coal-fired power plants,
but in India's case, it hasn't been able
to get enough coal lately, which has
driven up prices. Meanwhile, a lack of
rain has left the country's
hydroelectric dams -- some 19 percent
of its generation mix -- without the
water they need to generate power.
Overall, India's peak power demand
has been outstripping supply by
about 9 percent during the latest
summer peaks, when air conditioning,
a mark of an upwardly mobile
lifestyle, starts to kick in.
All of that inefficiency and waste has a
price. The Wall Street Journal reports
that India's poor infrastructure
consistently shaves about 2 percent
from its annual GDP growth. India's
fast-growing technology sector has
had to build its own power plants,
essentially, to make sure facilities don't
break down or sit idle. Most of that
backup power comes from diesel
generators, which are inefficient and
pollute the neighborhoods they run
in.
Smart Grid From the Bottom Up
But at the same time, all that backup
power could be one key to unlocking
India's smart grid potential. Indeed,
microgrids -- islands of power
generation and consumption that can
run themselves, or maybe help the
grid when it's stressed -- are how
India's grid is going to get smart, at
least in the short term.
Microgrids can range from showcase
technical campuses like Cisco and
Wipro's Lavasa City "e-city" project
outside Mumbai, to commercial-scale
business offerings like the one
Echelon is doing in a high-end
residential development in
Hyderabad. Most of India's
commercial and industrial buildings
have backup power of some kind.
Adding metering and control
capabilities could help justify drawing
that power more often -- perhaps
preemptively to avoid stress during
peak demand times.
It's important to remember that the
level of organization of projects like
these is strictly 'behind the meter.'
The economics of backup power
require customers to worry about
their own reliability first. Using them to
help the grid solve its problems is, for
now, awaiting more development on
the utility side of the smart grid, Varun
Nagaraj, Echelon's senior vice
president of product management,
told me earlier this year.
Right now the mood is cautious for
the grid giants working in India. IBM
launched a big smart grid planning
analytics system for the government's
Bureau of Energy Efficiency last year,
and Guru Banavar, CTO of IBM's
Global Public Sector unit, told me this
week that IBM is working with utilities
in Delhi and elsewhere in India.
Still, "we've not reached the front
where there's a big information
technology breakthrough," he said.
That's mainly because the grid is so
old and decrepit that it needs a
massive government-led investment
to get it up to speed. "At a campus
level, there's a lot more action going
on," he said, with IBM taking part in
"Smart City" developments with a host
of Indian governments.
Some grid projects are underway. In
March, Siemens announced an 18.5
million euro ($24.3 million) contract to
provide SCADA and distribution
management systems for eight cities
in the Indian state of Maharashtra,
including Mumbai. The idea is to give
the grid sensors and communications
to detect faults, direct outage repairs
and spot power theft, among other
functions. Indian IT giants like Wipro,
Infosys, HCL and TCS are deploying
technology to support solar power
arrays, campus-wide microgrids and
the like.
But a grand-scale (read: billions of
dollars) effort to tie India's six grids
together hasn't been forthcoming,
despite the formation of various
central government forums and task
forces. In March, a government
consortium announced plans for
$100 million in grants for smart grid
projects. But since then, the
government has scaled back its
promise for $1 trillion in general
infrastructure improvements, leaving
the fate of the smart grid funding
unclear.
Solar Power to the Rescue?
In the meantime, India's potential to
become the next hot solar power
market may be cut short by an
inadequate grid infrastructure. Dr.
Murray Cameron, COO of Phoenix
Solar AG, told us in May that India's
high-voltage grid was relatively stable,
making large-scale solar farm
integration tenable. But the "low-
voltage grid is in a sad state [and] the
medium-voltage grid is shaky," he
said.
Perhaps solar-equipped microgrids
could help solve the problem. India is
emerging as a hotbed for off-grid
solar power, with the potential for
installing more than 1 gigawatt per
year by 2016, according to GTM
Research and Bridge to India. More
than a third of the country lacks
electricity at all, making rural
micropower projects a big target.
But hospitals, factories, government
buildings and apartment blocks could
also generate their own power to help
shave a portion of their power use,
and thus cut down on peak overloads
like the one suspected of causing this
week's disaster. Adding solar to a mix
of generation, demand response and
energy storage systems could make
those systems self-supporting.
India's government wants to boost
solar power from today's 1,000
megawatts to 20,000 megawatts by
2022. Still, solar's economics face
challenges in India, including a split
between state government incentives
for power and the prices that power is
actually bought and sold at on the
nation's grid system, as The
Economist pointed out in an April
article. Whether solar power as a
microgrid backup, rather than a grid
resource, can make the economics
work is a more difficult question to
answer.
