The CFL Calculation

Posted in General on June 29th, 2010 by Ravi

I haven’t calculated this earlier, but am going to calculate on this post. Don’t really know what the outcome would be. Here goes.

The terms that I would be using would be easily understood by Indians as I am an Indian. If google brought you here from USA or elsewhere, read on if you must as I am not sure what values apply in your country.

The Tube Light is a tube filled with some florescent vapor and when electrons pass through the tube, the vapor glows. The cost of making this vapor glow is 40 watts of power.

This costs Rs 50 in Pondicherry, a Union territory in India were almost everything is cheap. Power in Pondicherry costs from Rs 0.55 to 1.75 per KWh.

So with a tubelight’s life of 1000 hours,

Time run per KWh = 1000/40 = 25 hours.
(want me to break this down for you? 40 watts = .04 KW, and to get the value for H, you invert .04 and you get 25, so the answer is 25 hours)

Total power consumed in Lifetime of a tube light = 1000 / 25 = 40 KWh.
(1000 hours of lifetime and 25 hours per KWh)

So the total cost of usage of a tube light in Pondicherry for its lifetime is Rs 50 for buying it, and Rs 70 to run it at the cost of Rs 1.75 per KWH for 40 hours, the total comes to Rs 120.

The CFL has a lifetime of 5000 hours. Thats 5 Tubelights, which cost 250 in total at Rs 50 each, and a 22 Watt CFL costs only Rs 200.

Whoa, there were have it, I guess I have the answer. Do your math for the CFL power consumption guys. Yes, I guess CFL is cheaper

Time run per KWh of CFL = 1000/22 = 45.45 hours.

Total power consumed in lifetime = 5000 / 45.45 = 110 KWh

Total cost of power = 110 * 1.75 = Rs. 192.51

Total cost = Rs 192.51 + 200 = 392.51.

Comparing with the Tube Light,

Rs 120 per 1000 hours is Rs 600 per 5000 hours. And CFL comes to about Rs 400 only. Yes, looks like the CFL is a bit cheaper.

The production costs of CFL bulbs should be really low, I am sure these Philips and Wipro guys are making a big bunch of money selling these. These should be available in the markets for Rs 50 as I don’t think the cost making a CFL would be any more than making a Tube light, of course the CFL has a built in choke and starter setup.

So guys, go get CFL, consume less power, save the planet.

By the way, is there a better air conditioner that consumes lesser power as well? As I don’t think saving 22 watts is really going to save the planet while my AC is drawing 2000 watts non stop for about 20 hours a day :p.

Back by popular demand

Posted in General on January 4th, 2010 by Ravi

I have so many commenters telling me to get back to my fucking self. Pardon my profanity, but thats a message I got just now, asking me to stop posting PLR articles for traffic and linking and write shit about myself.

Well, here goes.

I, like most Indians, have a liking for Punjabi Pop. Not garbage like Daler Mehendi and Gurdas Mann. But music of higher levels of Bally Sagoo and Stereo Nation and stuff.

Taz-Mania was an album released by Stereo Nation, and heres my most favorite song in that album. Searched for it all over as I lost a hard drive and all my music in it some time last year, and am in an attempt to rebuild my entire collection. And guess where I found it. Raaga.com, the shittiest site I knew 8 years ago. Offering good quality streaming now, and they let me embed the player as well.

Are our accents really this bad?

Posted in General on August 1st, 2009 by Ravi

Are our accents this bad really? Or is Russell just making it sound funnier? Untill quite recently, I noticed huge similarities between Russell Peters and Salman Rushdie. Well, I am a low lying person, and suddenly came to my senses that the common thing between the both of them is that they both ate Indians, talking about India to Non Indian people everywhere. Russell makes fun of us, while Salman makes some sense, tries to project the richness of the countries without making the Europeans feel depressed or anything. Well, both need to do some Fastin and loose some wieght if they want to stop panting whe they talk.

Adsense Darted, DHL Carted

Posted in General on May 8th, 2009 by Ravi

Just like everyone else, I too monetize my blogs with adsense. And I do receive payments every month on a net-30 basis. Payments accumilated till the end of may will be paid by the end of june, and you get ot clear it by the first week of july.

Well. I have been really happy all these months, since Adsense sends its checks payable in India through DHL from Dublin. It used to. Untill now. I used to get the check on the 1st of 2nd of every month just like most others in India and the payment would hit my account on the 3rd or 4th. And I did pay an extra $25 charge for that express delivery. I thought it was well worth it.

At around the 20th of April, I got a mail from google sent out a mail to everyone in India that there will be no more Secure Express Delivery, and all checks to India would be sent through the local courier service called Blue Dart.

Well, when i had got the mail, I thought it was cool. Saving $25, and you get your cheques from google’s Hyderabad office. Great. I should get the cheque the next day itself then. Paymet issued on the 28th and I get the cheque on the 29th. Send it for lcearing on the 29th and I get the money by the 30th. The idea was cool.

Payment was issued on the 28th of April, and I waited till the 30th. People said that only on the 30th the cheque will be handed over to blue dart, and may 1st being a holiday we would get the chq only on May 2nd. Great. Will wait. Late hua to kya hua? Paise to bach gaye na. I waited till the 5th. No cheque. If it was DHL, I would have gotten the money by 4th.

6th and 7th. No cheque. Today is 8th.

At a few forums where I participate, people just scare me. Looks like Google has made Hyderabad its center for cheque printing. It has been sending cheques to Russia and many other places in Asia and Europe from Hyderabad. People are saying that only after printing all those International Cheques, google will be sending the cheques for Indians.

Holy Crap.

And, people also say, it is India, and there would be several other problems that google might never have imagined.

1. Powercuts
2. Printer Problems
3. Delay in the arrival of service engineers to fix the printter.
4. Traffic delaying the delivery of cartridges for the printers.
etc.

Google moved their entire operations at Dublin and Singapore to Hyderabad because all Indians are loosers and work for food and nothing more and wont mind mesothelioma if they get it.

Well, at this rate, I dont think the cheques would arrive anytime sooner than the 31th of May. And we can only hope that google sorts out its operations soon and make the Hyd unit as efficient as Dublin, and make sure that we all get our cheques in time.

A blog is vulnerable

Posted in General on October 2nd, 2008 by Ravi

Powerful as a blog may be, it is quite vulnerable to spam attacks as well. You have a section called comments below your blog post, and people can write what they like. Luckily wordpress allows you to moderate any comments that are posted on your blog, and therefore you can make sure that no spam comments that promote websites that sell pharmaceutical delights on your site. Though there is Askimet, some comments in my blogs do manage to get into the waiting for moderation area and I am having to mark them all as spam.

And sometimes spammers find a good way to attack your blog and byepass askimet, I dont really knwo how that is done, and I dont wish to specialize in that in any ways, and marking them all as spam one by one is a tough job. A real tough job. I will not find time to do this from the office, so I have to do it at home. And when you have too many comments, you would not want to miss out the good comments and mark them as spam as if you do so you will no longer get a comment from that user again. It is a tough job. Well, with the help of a good computer monitor, a keyboard and a mouse, and ofcourse with good computer desks the job should be simple. Think of the other Indians who use their dining tables as their computer desks and sit at awkward positions to use their keyboards and mice that would probably be at the same level of the base of the monitor.
