A inspiring story - Husk Electricity. Made in Bihar :-)

 
http://opinionator.blogs.nytimes.com/2011/01/10/a-light-in-india/

Some quotes from article,
When we hear the word innovation, we often think of new technologies or silver bullet solutions — like hydrogen fuel cells or a cure for cancer. To be sure, breakthroughs are vital: antibiotics and vaccines, for example, transformed global health. But as we’ve argued in Fixes, some of the greatest advances come from taking old ideas or technologies and making them accessible to millions of people who are underserved.

In vast stretches of the developing world, after the sun sets, everything goes dark. In sub-Saharan Africa, about 70 percent of the population lack electricity. However, no country has more citizens living without power than India, where more than 400 million people, the vast majority of them villagers, have no electricity. The place that remains most in darkness is Bihar, India’s poorest state, which has more than 80 million people, 85 percent of whom live in households with no grid connection. Because Bihar has nowhere near the capacity to meet its current power demands, even those few with connections receive electricity sporadically and often at odd hours, like between 3:00 a.m and 6:00 a.m., when it is of little use.

This is why I’m writing today about a small but fast-growing off-grid electricity company based in Bihar called Husk Power Systems. It has created a system to turn rice husks into electricity that is reliable, eco-friendly and affordable for families that can spend only $2 a month for power. The company has 65 power units that serve a total of 30,000 households and is currently installing new systems at the rate of two to three per week.

But the lessons here go beyond the fortunes of Husk Power. What the company illustrates is a different way to think about innovation — one that is suitable for global problems that stem from poor people’s lack of access to energy, water, housing and education. In many cases, success in these challenges hinges less on big new ideas than on collections of small old ideas well integrated and executed. “What’s replicable isn’t the distribution of electricity,” says Pandey. “It’s the whole process of how to take an old technology and apply it to local constraints. How to create a system out of the materials and labor that are readily available.”

Travel - A quick look !

You start the day by taking bath, wearing clothes, having food, travel to office, work, travel back to home, watch tv and sleep. If you see these activities they are day-to-day ones which cannot be avoided. In all these activities travel is one activity which has taken considerable time from our life which needs some attention.

From the time we started to go to school until now on all days we all have traveled. Starting from school days until now if I had to calculate total time I had traveled by taking 2 hours a day for travel it would come around,

school - 170 days * 12 years * 2 hours -> 4080 hrs -> 170 days(6 months approx.) - after calculating this looks funny... 170 days I have traveled which is equivalent to 1 extra year of studying school :-).

college - 4 years * 220 days * 2 hours -> 1760 hrs -> 73 days(2.5 months)

work - 7 years * 240 days * 2 hours -> 3360 hrs -> 140 days(4.5 months)

It is totally 13 months of travel in my life time until now. Or else we can say like I have wasted more than a year of my life by just traveling in Chennai roads. Is it ok to waste your life time in travel ?.  If you say its ok, then, think of years until you retire(say u work for 55 years, then, 25 more years * 240 days * 2 hours -> 12000 hours -> 500 days -> 17 months). So totally it will come around 2.5 yrs(13 + 17 months).

On considering the above calculation, which would be wise solution for us,

1. Join a school which is in your locality ?(may be our kids can benefit)

2. Join a college which is in your locality ?(i guess this is highly impossible given the urban setup.... solution can be staying in college hostel)

3. Join a office which is in your locality ?(given changing times and uncertainty of staying in single job makes this difficult).

4. Travel anyway. Reduce the travel by 1/4th of the time you travel now. This can be achieved only if our infrastructure improves exponentially. Like having good subway/mrts train connectivity in cities, having good roads, etc.. Hope, this happens.

Nokia and its bureaucracy

A few years before Apple introduced the iPhone, research engineers at Nokia prepared a prototype of an Internet-ready, touch-screen handset with a large display, which they thought could give the company a powerful advantage in the fast-growing smartphone market.

As chief, Stephen Elop must regain Nokia’s lost ground in smartphones.
The prototype was demonstrated to business customers at Nokia’s headquarters in Finland as an example of what was in the company’s pipeline, according to a former employee who made the 2004 presentation in Espoo.
But management worried that the product could be a costly flop, said the former employee, Ari Hakkarainen, a manager responsible for marketing on the development team for the Nokia Series 60, then the company’s premium line of smartphones. Nokia did not pursue development, he said.
“It was very early days, and no one really knew anything about the touch screen’s potential,” Mr. Hakkarainen explained. “And it was an expensive device to produce, so there was more risk involved for Nokia. So management did the usual. They killed it.”

How far this is true ?

Bitter Honey

Those who think daily a spoon of Honey is good for health, beware of honey available in India.
Honey available in retail outlets in India are of sub-standard. Look at the following article,


NEW DELHI: That spoonful of “guaranteed pure” sweetness may be hiding a bitter secret. Branded honey sold in India is likely to be contaminated with harmful antibiotics, according to a new study by the Centre for Science and Environment.
CSE's Pollution Monitoring Laboratory tested 12 leading brands of honey sold in Delhi, including those made by Indian companies such as Dabur, Himalaya, Patanjali, Baidyanath and Khadi as well as by two foreign companies based in Switzerland and Australia. Scientists found high levels of six harmful antibiotics in 11 samples, with only the Indian Hitkari brand coming out clean.
The contamination is the end result of a murky chain, which begins when antibiotics are fed to bees to prevent disease, promote growth and increase honey production to meet commercial targets. When they make their way into your daily spoonful of honey, these substances could damage the blood, kidneys, liver, bones and teeth. More importantly, they create resistance in the body to prescribed antibiotics when you really do fall ill, says the CSE report.
Most developed countries have banned or strictly regulated antibiotics in honey, and Indian companies must meet those standards when they export their products. However, in a stinging example of double standards, most Indian companies are dumping their contaminated honey on the domestic market, since there are no regulations here, says the CSE.
Dabur Honey — which has captured 75 per cent of the Indian market — had the antibiotic Oxytetracycline at nine times the level that is permitted for exported honey. It also had significant amounts of two other drugs completely banned for use in honey. If the sample was placed for export to the U.S. or the European Union, it would have been rejected.
Interestingly, Dabur was recently involved in a controversy in Nepal, where leading newspapers claimed that its honey was substandard and used harmful chemicals. The company dismissed it as part of a “smear campaign” against Indian products, but the sticky claim has now come from an Indian source.
Nectaflor Natural Blossom Honey, made by Narimpex of Switzerland, had the largest number — five — of the six antibiotics that it was tested for, including the highest levels of ampicillin and erythromycin, both of which are not permitted for beekeeping in any country. It would be illegal to sell it even in Switzerland itself. Similarly, Australian brand Capilano Pure & Natural Honey, sold in 40 countries, violated standards set in its home country.
“It is clear that foreign companies are taking advantage of the lack of regulations in India. After all, if our government does not care about the health of its people, why should these companies care?” said CSE director Sunita Narain, at the release of the study on Wednesday.
“We have standards for antibiotic contamination in the honey we export. The government even tests and certifies that exported honey meets health and safety regulations. But we do not have any standards for domestic honey. This is clearly unacceptable,” she said.

Its really sad that the well know companies like Dabur, Hamilaya, etc. are into business of making profit at any cost.

The test comes from Japan where it is used as an IQ test for jobs and university entrance, mainly related to IT. It should take you less than 15 minutes to complete:
The rules are as follows:
Aim - Get everyone - Father, Mother, 2 Boys, 2 Girls, Policeman and the red haired arrested girl in striped uniform to the other end of the river. You have the boat to ferry them across and the conditions are as follow:

1.  Only two people can travel at once
2.  Dad can not stay with the girls without the presence of the mother
3. Mum can’t stay with the boys without the presence of the father
4. The arrested red-hair girl in stripy outfit cannot stay with any of the family members, unless accompanied by the police officer.
5. Only the Police officer and the parents can drive the boat across the river
