Cars: Fuel cell Vs Electric

Electric car-makers like Tesla, are constructing mega factories for mass production of Li-ion batteries to reduce the price of cars. On other hand Japanese companies are investing heavily on hydrogen Fuel cell technology. This race is not about who will come first, rather who will sustain in global market finally. Presently and decisively Electric vehicle driven by Li-ion batteries are leading the trend with reduction in battery pack price and increase use of solar energy. Electric vehicles made lot of improvement in recent time. Much of it can be attributed to Tesla-first electric car-maker who took concept of electric cars much seriously than any other car-maker. They set very high standard for electric cars and make much needed improvement to compete with traditional IC engine cars running on gasoline. Charging time reduced from hours to several minutes. Mileage too increased considerably. All these improvement made Electric Vehicle ( EV) a better solution to IC engine causing pollution. EV do not cause air or sound pollution and they are safe car. However, they need electricity to charge batteries. Sometimes electricity is produced by burning coal, which again cause pollution. Solar power is a workable solution. However, with present efficiency of solar cell, it will be difficult to fulfill future domestic demand. Thus, electric vehicles are not the best solution for future in developing countries where managing domestic electricity demand is a challenge.

In future, people will prefer car with inbuilt energy powerhouse. A car, which can run longer than normal electric vehicle and IC engine without creating pollution and have a safe quick re-filling. As soon as hydrogen or any other fuel cell meet these criteria then that will be the turning point in history of Fuel cell vehicle (FCV). At present, peoples are concern about safety of using hydrogen as fuel. Of course, electric vehicle are safest compared to FC and IC engine. Nevertheless, with advancement in technology, fuel cell will become safer than IC engine, which we used for decades. The biggest obstacle for fuel cell cars is filling station, which require lot of money in establishment. Without filling stations, no one will buy such cars. Slowly but surely as filling station will increase, demand for FCV will increase too. With improvement in technology and mass production, price of cars fitted with Fuel cell will decrease considerably.

As we have saying, “Slow and steady wins the race” it is possible that future belongs to Fuel cell Vehicle. Batteries are temporary solution. If we find a way to fill a vehicle directly from hydrogen cylinders then we can cut off expansive filling station requirement too.Normally a FCV requires 35-90 MPA pressure. In market, cylinders are available up to 90MPa as well. We only need a hose pipe with connector to fill the Car tank. Some innovative ideas required to make FCT a feasible reality. Japan is investing hugely to make improvement in fuel cell. Only future will tell which technology will pass the test of time.

Can we destroy Currency?

 

Lot of people consider that every time money is spent on some seemingly no profitable work, money is wasted. For example: Elections and wedding parties. However, money spent is not necessarily money waste. Actually, every time someone spent a big amount of money it boosts the economy. Money is wasted when it is destroyed without information. The worst thing for economy is when people keep money stored in their homes or in Swiss bank as black money. If you stop circulation of huge amount of money, it will drastically affect economy of country.

Irrespective of popular notion that when we spent money extravagantly, we are ruining our country wealth, the truth is we must support every such event. Let us take the example of election. In digital India, elections are also digitalized. 24 x 7 you can see advertisements of political parties on electronic and print media. In four years, Modi Government spent total of Rs 4,343.26 crore on advertisements and publicity through different media, according to a RTI. This money could have been used for some more important works too, but it will be wrong to state that this money is wasted. Money only changed hands. While changing hands a fraction of it will go to poor labourers, spot boys, technicians, wall painters and junior artists. Though, that might not be the intention but it is by-product of publicity expenditure. Thus, money spend on publicity is not wasted. It just moved from a political entity to media houses and their workers, journalist, technicians and artist.

Similarly, in marriages, when people spent lot of money, this money does not go anywhere. It just changes hands. More importantly, in some cases, black money entered into circulation once again.

The question that arises in mind is how money is actually wasted or destroyed. Talking literally, if you burn money without informing government, it will be lost permanently and it will cause deflation. Deflation means cost of goods will decrease. Since only small percentage of net wealth is in the form of currency, burning few notes will not create any effect. However, please note that, burning currency notes is illegal in many countries.  Even if your currency is damaged during natural disaster or otherwise, you can send it for replacement. Never throw or destroy any denomination of currency notes.

Let us take another example: An aeroplane is destroyed in mid-air with 100 passengers. All died on board and plane was lost in Deep Ocean. Suppose cost of plane was 1 million $. Is this 1 million $ destroyed? No, it’s not. Cost of plane is determining by the material and labour used. When you purchased the plane, you paid its full cost. When the plane was destroyed, your individual wealth reduced, but not the currency in circulation. Hence, we can say that individual’s wealth keep increasing or decreasing, but money does not decrease. Money only changes hands.

GOD means Christian God.

 

First of all thanks for those people who piss me off by their flawed arguments and illogical content. It gives me new ideas to write a new post. This Post is about concept of God in various religion and culture and how wrongly we start writing or talking about God without explaining first which God we are talking about? There are theist, deist and agnostics. All of them believe in some kind of creator. However, every group has different concept of creator. Even in each group, different religion has different views or belief about Creator.

Normally, we do not translate names when we translate text from any language to English. However because of Christianity being most populous religion and English being international language from centuries the word God is being used for all Gods of different religions and even for Gods with different attributes. Not only that, it also has a plural and feminine form. I will use Supreme Being for the God in this post to differentiate the God of Christianity from other religion.

In Islam Supreme Being is known as Allah. Allah ever exists. He is neither created nor born not will die. He does not have any wife, son, daughter, mother or father.  He is the one, nothing is like him nor is he like anything.

“He did not beget (give birth) and He was not begotten (given birth to).” (Surat Al-Ikhlas, Chapter 112, verse 3).

There are many other attributes of Allah which need to be considered to properly define who Allah is. For example, Allah is forgiving, merciful, just, omnipotent and omnipresent. He has not made any demigod or goddess or anyone who has share in his powers.

There is a mark difference in the definition of Allah and Christian God. A Christian God first and foremost is believed to have a begotten son. The Son himself is a god! Not only that, there is a holy spirit which is also part of God himself. In this way, Christians believe in trinity.  Hence, translating God as Allah or Allah as God is wrong practice.

Coming to Hinduism, Hindus also have concept of one Parabrahman or Supreme Being. However, his nature is unknown. He created other Gods and goddess who took birth on earth as their Avatars. Like Ram and Krishn were believed to be Avatars. One of my fellow blogger told me “ There are five eternal entities. (1)Jiva – the creatures, (2) Ishwar- the deities which include indra, brahma, Vishnu, Shiva and all. (3)Maya- the only non living entity which controls time and our actions.  (4)Brahman (Akshar/chidakash/satchitanand) the cause of creation of infinite universes. (5) Parabrahman/Purna-purushottam/Adi Vishnu : the one who transcends all and even Akshar. Although Akshar is the highest entity, Purna Purushottam is the one who transcends Akshar.”

From above, you can see there is not just one God doing everything in hindu mythology. There are layers of God. Translating Hindu God as “God” is wrong. However, people do it all the time for simplicity or because of influence of English and Christian religion. It is like translating Modi as Trump in English. It is absurd to translate names. It is more absurd when we translate any other religious deity or supreme being as God. Before starting any argument or debate about God, we must first define which God we are talking about!

Some sayings of Epicurus — Phil Ebersole’s Blog

The blessed and important nature knows no trouble nor causes trouble to any other, so that it is never constrained by anger or favor. For all such things exist only in the mind. Death is nothing to us: for that which is dissolved is without sensation; and that which lacks sensation is nothing to us. […]

Indian Elections and Dirty Politics

People say that if you repeat lie 100 times it became truth. Same is happening in India under BJP Government. Politicians are playing with history distorting and twisting it. Even The Pradhan Sevak (Mr. Modi) is in front row in misquoting history, especially during election campaign. Recent election campaign, in Karnataka are no exception. Here Mr. Modi try to portray Nehru as insulting Field Marshall Cariappa and General Thimayya. Modi said “In 1948 after defeating Pakistan, General Thimayya was insulted by PM Nehru and Defence Minister Krishna Menon”.However, if you read history, dates and incidents he mentioned does not fit with what he said. General KS Thimayya was not the Commander-in-Chief of the Indian Army in 1948.

Being Prime Minister of India is a big responsibility. We, the citizen of India, expect more accurate historical facts from our PM. Mr. Modi is first PM who is more interested in election campaign than in National issues. More than hundred peoples died in recent storm Rajisthan, UP and near by areas but Mr. Modi remain busy in election rallies in Karnataka. He sent condolences on his twitter account as if every india is well verse in English and follow him on twitter. 

“Saddened by the loss of lives due to dust storms in various parts of India. Condolences to the bereaved families. May the injured recover soon.

Have asked officials to coordinate with the respective state governments and work towards assisting those who have been affected: PM”

In India there are 29 states. Each state has the election in every 5 years (60 months). This means, approximately every two month there is a state election in India. Each election takes around one month of election campaigning and shortlist of candidates etc. Hence, if a Prime minister will take active part in election, he has to dedicate six months of every year in elections alone. In those six month who will do the Prime Minister’s work?  I am not saying that Mr. Modi is the first or the last PM to take part in elections. However, in my life span, I have not seen any PM more committed to every state election than Mr. Modi. This may be good for his party but not good for a Nation. BJP is in full majority in centre. They already have government in 18 states. This is the time when BJP ministers and our PM must work for country and win elections based on their work not by creating communal divide in society.  

Deep Space Exploration and Mission Mars

With the present speed of rockets (though it is still a marvel of human capability) future of deep space exploration is gloomy. However, NASA and other space agencies are working on different propulsion fuel including nuclear to increase the speed of rockers. Hopefully, sooner than later we will have rockers fast enough which can make the journey to mars shorter than three months.

In last 50 years of space exploration, we have not achieved anything amazing. Last big thing was when man landed on the moon. Since then we saw a dry period in space exploration. All space agencies are busy in sending satellites and rovers in outer space. Even though, human have made outstanding growth in technologies whether it is Robotics, aviation, AI, automation, generating clean energy and much more but same growth was not seen in deep space exploration. We are certainly capable of becoming multi planetary species. Solutions were available but Governments are reluctant!

Private companies bring new ray of hope in this regard. I am a huge fan of Elon Musk, a man behind companies like Space X and Tesla. He actually makes us feel that we already usher in 21st century. Anything is possible; we just need to dream big. The recent launch of falcon heavy with two boosters landing back simultaneously is just outstanding achievement. Such success can’t be confined to a city or nation. It is a global achievement. Though I have not contributed anything in this success but I feel equally proud about success of technology built by human. It took human nearer to the mission Mars.

There are so many enthusiastic people who are willing to go to Mars even when they know that Mars is not hospitable for life. But space agencies are busy in testing their robots and collecting more data. There was a time when people had only small boats, no navigation system, and no communication system back to the land but still people used to take risk and sailed to unknown lands without having slightest information about what kind of animal’s lives in ocean and what they might find on another land mass. Many died in such expedition, but some survived and came back successfully. They didn’t wait for right technology or full information. Their curiosity drove them far and wide. We must learn from them and be ready to take calculated risk.

Today we have technology. We have resources but we do not have will to take action. One reason might be that as we are getting more information about Mars, we find it more and more inhospitable for human being. We need more reason for sending human to mars than we previously though. It will not be a honeymoon journey. With present speed of Rockets, it took 6 to 8 month to reach Mars. On mars, you will not find anything to eat or drink, no oxygen to inhale and you will be surrounded by harmful radiation. If that is not enough, Mars gravity is much less than earth. Which is not a good news for human well-being if they stay for long time!

There are many more mind-blowing life and threatening facts about red planet. Temperature: minus 60 degrees Celsius which can still go down to minus 100 degrees Celsius. A summer day on Mars may get up to 20 degrees C near the equator, but at night the temperature can again drop to about minus 73 C. Mars also has big dust storm.

So, even if we will make homes on mars, still life will be difficult and whole day we have to remain inside a small room and in night we have to wear space suit to go out because mars atmospheric pressure is 0.6% compared to earth atmospheric pressure. Choice of food will be limited and water and air will be re-cycling again and again.

Disadvantages are far more than advantages to live on Mars. If we had a planet or moon with at least water on it or at least atmosphere with oxygen, then it would be worthwhile to haste. With all life threatening conditions and nine month-long journey time, the only viable thing to make on mars is space station for maintenance of rockets and rovers, research facilities, cheap energy producing plants and re-filling of rockets. All this can be achieved by sending robots rather than humans. Only few human will suffice to control operations. Populating Mars is a distant dream which can only be realise by Terra forming Mars. For present time, robots are better solution.
