Mark Bent's BoGo Light solar-powered flashlight achieves escape velocity — Episode 2: New York Times takes it and runs with it

Uohu_1

In yesterday's Times a story by Will Conners and Ralph Blumenthal featured the latest on Mark Bent's quest to light up Africa.

You may recall Episode 1, which appeared here on January 23, 2007 in response to an email from Mr. Bent.

Long story short: Close to two billion people — one-third of the world's population — have no affordable access to artificial light.

Chantal Duke, executive assistant to the head of the Awty International School, noted in the Times article, "In places where there is absolutely no electricity or running water, having light at night is a luxury many families don't have and never did and which we take for granted in developed countries."

Here's the piece.

    Solar Flashlight Lets Africa’s Sun Deliver the Luxury of Light to the Poorest Villages

    At 10 p.m. in a sweltering refugee camp here in western Ethiopia, a group of foreigners was making its way past thatch-roofed huts when a tall, rail-thin man approached a silver-haired American and took hold of his hands.

    The man, a Sudanese refugee, announced that his wife had just given birth, and the boy would be honored with the visitor’s name. After several awkward translation attempts of “Mark Bent,” it was settled. “Mar,” he said, will grow up hearing stories of his namesake, the man who handed out flashlights powered by the sun.

    Since August 2005, when visits to an Eritrean village prompted him to research global access to artificial light, Mr. Bent, 49, a former foreign service officer and Houston oilman, has spent $250,000 to develop and manufacture a solar-powered flashlight.

    His invention gives up to seven hours of light on a daily solar recharge and can last nearly three years between replacements of three AA batteries costing 80 cents.

    Over the last year, he said, he and corporate benefactors like Exxon Mobil have donated 10,500 flashlights to United Nations refugee camps and African aid charities.

    Another 10,000 have been provided through a sales program, and 10,000 more have just arrived in Houston awaiting distribution by his company, SunNight Solar.

    “I find it hard sometimes to explain the scope of the problems in these camps with no light,” Mr. Bent said. “If you’re an environmentalist you think about it in terms of discarded batteries and coal and wood burning and kerosene smoke; if you’re a feminist you think of it in terms of security for women and preventing sexual abuse and violence; if you’re an educator you think about it in terms of helping children and adults study at night.”

    Here at Fugnido, at one of six camps housing more than 21,000 refugees 550 miles west of Addis Ababa, the Ethiopian capital, Peter Gatkuoth, a Sudanese refugee, wrote on “the importance of Solor.”

    “In case of thief, we open our solor and the thief ran away,” he wrote. “If there is a sick person at night we will took him with the solor to health center.”

    A shurta, or guard, who called himself just John, said, “I used the light to scare away wild animals.” Others said lights were hung above school desks for children and adults to study after the day’s work.

    Mr. Bent’s efforts have drawn praise from the United Nations, Africare, Rice University and others.

    Kevin G. Lowther, Southern Africa director for Africare, the largest American aid group for Africa, said his staff was sending 5,000 of his lights, purchased by Exxon Mobil at $10 each, to rural Angola.

    Dave Gardner, a spokesman for Exxon Mobil, said the company’s $50,000 donation in November grew out of an earlier grant it made to Save the Children to build six public schools in Kibala, Angola, a remote area of Kwanza Sul Province.

    “At a dedication ceremony for the first four schools in June 2006,” Mr. Gardner said in an e-mail message, “we noticed that a lot of the children had upper respiratory problems, part of which is likely due to the use of wood, charcoal, candles and kero for lighting in the small homes they have in Kibala.”

    The Awty International School, a large prep school in Houston, has sent hundreds of the flashlights to schools it sponsors in Haiti, Cameroon and Ethiopia, said Chantal Duke, executive assistant to the head of school.

    “In places where there is absolutely no electricity or running water, having light at night is a luxury many families don’t have and never did and which we take for granted in developed countries,” Ms. Duke said by e-mail. Mr. Bent, a former Marine and Navy pilot, served under diplomatic titles in volatile countries like Angola, Bosnia, Nigeria and Somalia in the early 1990s.

    In 2001 he went to work as the general manager of an oil exploration team off the coast of the Red Sea in Eritrea, for a company later acquired by the French oil giant Perenco. But the oil business, he said, “didn’t satisfy my soul.”

    The inspiration for the flashlight hit him, he said, while working for Perenco in Asmara, Eritrea. One Sunday he visited a local dump to watch scavenging by baboons and birds of prey, and came upon a group of homeless boys who had adopted the dump as their home.

    They took him home to a rural village where he noticed that many people had nothing to light their homes, schools and clinics at night.

    With a little research, he discovered that close to two billion people around the world go without affordable access to light.

    He worked with researchers, engineers and manufacturers, he said, at the Department of Energy, several American universities, and even NASA before finding a factory in China to produce a durable, cost-effective solar-powered flashlight whose shape was inspired by his wife’s shampoo bottle.

    The light, or sun torch, has a narrow solar panel on one side that charges the batteries, which can last between 750 and 1,000 nights, and uses the more efficient light-emitting diodes, or L.E.D.s, to cast its light. “L.E.D.s used to be very expensive,” Mr. Bent said. “But in the last 18 months they’ve become cheaper, so distributing them on a widespread scale is possible.”

    The flashlights usually sell for about $19.95 in American stores, but he has established a BoGo — for Buy One, Give One — program on his Web site, BoGoLight.com, where if you buy one flashlight for $25, he will buy and ship another one to Africa, and donate $1 to one of the aid groups he works with.

    Mr. Bent, who is now an oil consultant, lives in Houston with his wife and four young children. When he is not in the air flying his own plane, he is often on the road.

    Traveling early this month in Ethiopia’s border area with Sudan, Mr. Bent stopped in each town’s market to methodically check the prices and quality of flashlights and batteries imported from China.

    He unscrewed the flashlights one by one, inspecting the batteries, pronouncing them “terrible — they won’t last two nights.”

    On his last day along the border, Mr. Bent visited Rapan Sadeeq, 21, a Sudanese refugee who is something of a celebrity in his camp, Bonga, for his rudimentary self-made radios, walkie-talkies and periscopes.

    The two men huddled in the hut, discussing what parts would be needed to power the radio with solar panels instead of clunky C batteries. “Oh, I can definitely send you some parts,” Mr. Bent said. “You can be my field engineer in Ethiopia.”

....................

First light, then radio, soon internet: it's long past time for my visitors map (top) to show activity out of Africa.

Full disclosure: After my January 23 post, Mark Bent emailed me and offered to send me a BoGo Light.

I accepted.

It's hanging from a patio door handle not eight feet from me at this very moment, getting plenty of sunshine so it can do what it does this — and every — evening here at bookfofjoe World Headquarters™®.

Comments

One of the great things about the BoGolight, with it's built in battery charger, is this: Every LED flashlight that I have found is powered by 3 (that's three) AA or AAA batteries. What makes this inconvenient to use rechargeables is, every NiCad or NIMH battery recharger that I have so far encountered charges batteries in pairs. This means that you would have to cycle thru 6 batteries to have fully charged back up batteries,
If you use your imagination you might see how this could be complex after a while. Mixiing up 1/2 charged and totaly discharged batteries is a no no. NOW with the BoGolight with it's internal charger we have solved that problem. AND by replacing the NiCad batteries with NiMH bats we do not have to worry about the memory effect that NiCads have when you don't discharge them all the way. Now we can have a light sitting around charging every day that will always be (assuming enough direct sunlight) fully charged and ready to give us at least 5 hours of light. Considering that the latest 1900 mah NiMH bats have twice the capacity of the included NiCads, the light will probably last for 10 hours. But you would not get to use that much light EVERY night, You would need a minimum of twice that much time every day to recharge it. Well at least with the NiMH bats you would also have the advantage that your batteries might last a lot longer by not "deep cycling" them. Deep cycling is a term used to describe fully discharging a lead acid battery. The life of lead acid batteries can be greatly extended if you do not use all of their capacity. I am working on my own theory that even NiMH, and the new Lithiulm-ion cell phone batteries, might benift from being kept nearly fully charged. We'll see if that proves out in a couple of years when my latest cellphone fails to be made obsolete just cuz you can no longer find batteries for it.

I am involved in a Human Development Project called Gramodaya ( Rise of rural communities)in India. How can we access BoGos or Indian villages?

Thanks and regards,

Vinod

I wish to acquire a BoGo light for some night schools. Where can I get one? How can I help Mark?

How do I get hold og BoGo Solar for distributing here in the rural areas ? Why cannot I make these here with your help just as you do in China ?

Just checking back in. It's the middle of October and I've had my BOGO light since June. And it is working just fine. The push button switch was a little problematic here last month (sometimes it would stick and not pop out far enough to cycle the switch from off to on & vice versa)and it would take a little rap of the lamp (which is rugged enough to take this mild form of punishment)against the palm of my hand to get the switch to cycle. For the last few weeks it has worked fine. The switch probably needed to get "broke in".
I hope the folks in the 3rd world countries that this light is destined for are able to figure out this little trick.

The light is more of an area, or flood light. It doesn't focus to a tight beam for seeing things in the distance. The usable light seems to stop at about 20 feet. But it has a broad beam and is very useful in a work environment like it was envisioned for.
