"Institutional capacity" is based on economics, which is what my sources argue. It is not due to a lack of brain power. And, that argument seems to hold if one were to accept the article i quoted above. In the specific case of Kaveri I am inclined to believe it is a material science issue...

When building engines we will be still reliant on imported components / systems especially fuel injection equipment (cost and complexity) and after treatment systems. Even if IA supports engine design and building this will continue to remain the case in foreseeable decades unless we start to devel...

What is needed is a program on the lines of the IGMDP for engines of various types for the airforce/navy/army. There will be a lot of failures. It may take a couple of decades like the IGMDP. But there will be a lot of success to . +1 Use Kaveri "technology" to develop a series of:- Turbo...

Arjun Mk1/Mk2 gets its diesel engines from Germany ONLY for economic reasons. It is not that Indians are incapable of designing and building such an engine, there are plenty of NRI in companies like Cat/Ford/GM heading such efforts. Also, if I am not mistaken India has taken up the next "gen&q...

Can someone explain the differences between Miller, Otto and Atkinson (and derivatives if any)? Otto cycle--regular 4 cycles Miller cycle--Intake valve (IV) is closed earlier so that the fresh charge is expanded in the rest of the intake cycle to cool it down. It is very popular in large diesel eng...

It turns out that even solar can give 24x7 power without adding any storage. For example if Brazilian electric grid is linked to Indian electric grid, then Brazil will supply India will solar electricity during night and India will supply Brazil with solar electricity during day. Given that laying ...

------------------------------------------------------------- In India we are so short of power most people would be comfortable with just 8AM to 6PM electricity. Maybe if GOI wants to be nice add in some storage and make it a 10PM electricity band. This argument over base power and intermittent po...

Yes, Solar PV is very expensive, need at least 1.5 lakhs for a 2 kva system w/ battery. Though it may have dropped a bit the recent declines. The huge problem is net-metering is not allowed in India, meaning you use the grid to balance your output rather than a battery. GOI is now finally working o...

I am working in the field of energy (mostly thermal) for the past 20+++ years. My views on the energy supply scenario may be out of sync with some people on this forum. Let us discuss our future energy options. My argument are based on the current technology and pricing. India is a growing economy....

Where can one buy Solar panels in India? What would it take for a typical home to make it grid independent? say 2 KVA I tried to install solar cells at my parents home in India in 2009 but it was very expensive. A company makes solar cells in our city and I talked directly to the representatives. A...

I suspect you asked this question on BR from an operational rather than philosophical/moral perspective. To the other responses I would add, also pragmatism, realism and a strong institutional desire to remain a professional fighting force(s). This is a very risky task in a country like India and s...

Folks i am confused why not empower CVC rather than bringing in another body called Lokpal I am assuming that you did not watch the video of Arvind Kejriwal's speech that was posted in BR a few months back. AFAI remember from that video CVC has only ~350 employees and so far it has not been success...

What is stopping / has stopped the Indian military taking over the government?

Newbie question:

What is the need for us to enter into a dollar swap with Japan for just $15 Billion when we have foreign exchange reserves of $300 billion?

Thanks.

I told you those riff raff 500,000+ private college engineers were good for something. :D Pardon my ignorance. What is the relationship between the number of graduating engineers to the exports? AFAIK small industries such as my Dad's are facing shortage of skilled labour as these guys have moved t...

If you give me specific examples of how something complex (except IT and semiconductor industry) was accomplished in a very short time frame in India I can then understand your basis of arguments. Otherwise I am not understanding where you are getting those time lines. As I said, you need to erase ...

^^Small nitpick. Tatas and other OEMs dont make the trailers. They make the truck portion called 'horse'. The trailers are mostly made by smaller private players. Though now many OEMs have started their own trailer-building units yet they are not much One more nitpick :D The 'horse' is usually call...

I do not know from where you got 5,10 or 20 years but there are many examples where it has taken longer. The basic crank arrangement of the commonly available engine (i.e ignoring rotary and other designs) has not changed since more than a century. Edison tried to build an electric car and look wha...

the mining cartel is a huge one with deep relations across several states. I would say that INC probably made a good amount of money from this scam. don't forget the Reddy brothers who are very close with YS Jagan in AP. this alliance was facilitated by INC's commercial interests and is therefore s...

All I want is a presidential form of government which is better IMO compared to the parliamentary form of the government. This will solve many issues that we are facing right now and will help us achieve our goals quicker. A strong Lokpal bill + presidential form of government will be a good combin...

Thanks Sanjeevji. Is that German? Can anybody translate the part relating to Rajiv Gandhi? Did this thing come up in Indian media in 1991?

I don't belittle it. But like I said, its a gross exaggeration that things take 20 years to get working. What will you buy? 'A' car or 'The' car? Obviously 'A' car. 'The' car would be a Formula-1 which I don't think I could afford. 'A' car is what you are building for the Indian, Latin American, mo...

The only thing I agree with you is "making """A""" car is not hard" That's what I'm saying. Making 'a' car is not hard. Making a best selling, very reliable car will be more difficult. But nothing is impossible nor is going to take 20 years to master. Cars ar...

I agree with them, we dont need the Carrefour's, Walmarts and Targets, they will only push for Chinese Manufacturing and wipe out our local Industry . I agree. Flooding the market with junk from china will destroy any incentive for manufacturing in India. There's hardly anything manufactured in Ind...

It is all not cut and dry when it comes to manufacturing. It is sometimes more of an art which has to come by practice. It will take some time for us to say we can do everything. At the moment we are not there. (I am talking in this post only about automotive stuff as my background is only in this ...

It is related to an automotive component. I am afraid I do not want to elaborate more than this in a public forum due to confidentiality issues.

Looked up the reference and I think you are talking about Azhiyar Dam of TNEB. Will check with them if it is like pumped storage reversoir.

devraj_d, One way of seeing the Euro meltdown is the forced equality of Germany with the rest is also melting away. This is a war just like the earlier ones. One solution after WWII was to bound Germany into economic relationships and keep de-warriorize them. So ECM was launched. Then came EU. And ...

one wonders what really gives these european economies their high value. maybe there are a few high tech companies here and there. but all the rest just looks like run of the mill companies doing stuff at a higher price than what would be done in the east .
