What is money?

Recently I came along a very good podcast in while the orator explained what is money and how the money (currency) came into existence. The explanation is very basic and complete. I am putting down the transcript of that presentation. The explanation is with respect to UK's economy but it seems that it generally applies to almost all the economies.

OK, so on with part One: What is money?
In brief, it’s anything generally accepted within a group as a means of exchange. Some things that have been used as money have value of their own such as gold or silver. This is known as the ‘intrinsic’ value. Other things used as money such as paper or shells have little or no value in themselves. Either way they are accepted as tokens to be used for the purchase of goods or services.
Another form of money in Britain for many centuries was the use of ‘tally sticks’ as receipts for large-value taxes. These were sticks of hazel, notched in a way to indicate the value. They were then split along their length, and the tax-man kept one half, while the other formed the receipt, which then could be used as money.
This system only finally ended in the 19th century when a fire being used to dispose of them got out of hand and burnt down the Houses of Parliament!
So how is money created? Most people think that money is just the notes and coins in their pockets and that it is created by the Government and spent into circulation. Well, some of it is.
In the 1940’s about 40% of the money in circulation was in the form of Government issued notes and coins. It is now only about 3%.
Why is this? In the Middle Ages, Merchants would put their spare gold into the safekeeping of the Goldsmiths, who had secure vaults. They were given paper receipts for the gold. The Merchants soon realised that instead of having to go to the Goldsmiths to take out some gold to use for payments they could pass on the receipts instead. This was how our paper money started.
The Goldsmiths also ‘loaned’ gold from their vaults. They charged interest on the loans. However, they could only lend actual gold from the supply they had in their vaults.
The greedy Goldsmiths realised that they could make loans in the form of the paper receipts that were being used ‘as’ gold. They then realised that most of the gold in their vaults was never taken out by the depositors.
So they started issuing receipts for much more gold than they actually had. As long as no one found out then there wouldn't’t be a problem. This increased the money supply, and as long as they were not too greedy, they wouldn't be found out.
So began the modern system called ‘fractional reserve’ banking.
The interest they charged on the loans eventually proved more profitable for some, than their work as Goldsmiths, and they had become the first Modern Bankers.
Gradually, the new banks took over the task of money-creation from the rulers (Kings, Governments, etc.), by issuing their own banknotes. This practice went on until it was outlawed in Britain in the 19th century.
The Bank of England, which was still a private bank, had special privileges granted to it, along with special responsibilities, and was the only bank then allowed to issue banknotes.
As the other banks could no longer print their own banknotes, and therefore couldn't’t make profits from loaning them out, so they started encouraging the use of cheques, and, more recently, credit or debit cards and electronic transfers.
This allowed them to continue to create money by making loans. As already noted, by the 1940s, after the Bank of England had at last been nationalised, about 40% of the money supply was still in the form of Bank of England issued notes and coins. This has now dwindled to only about 3%.

So How do banks create money?
When a bank makes a loan, it does two things: First it credits the borrower’s account with the money and records it as a ‘liability’ of the Bank. In other words, the Bank has entered into its system the ability for the borrower to go and spend the value of the loan at some future time.
Then it records the loan as an ‘asset’, owed by the borrower, to the Bank, again in the future. Thereby ‘balancing’ its books. In addition to the amount of the loan, the borrower has to pay interest. The money loaned does not come from any depositor’s account.
What it’s done is to create the money it lent out of nothing – or rather, out of account entries.
The bank has to keep available enough ‘reserve’ to meet demands for payments. This limits the extent it can expand the money supply by making loans. For much of the last century there was a statutory ‘fractional reserve’ required of around 10%. That means that banks had to keep reserves made up of notes and coins and deposits in their own accounts with the Bank of England.The reserves had to equal at least 10% of the amount they had out on loan.
In the 1970s this legal limit was lifted, so reserves have dwindled to much less, and the money supply has mushroomed!

Let’s look at an example.
With a reserve requirement of 10%, bank#1 starts with assets of £1,000 in its account. It now lends £900 to someone else, so it has £100 reserves and an ‘asset’ of the £900 owed to it.
With the remaining £100 in its reserves and the £900 loan it still has £1000 of assets.
The borrower then spends the money and it is deposited into another bank, Bank 2.
Bank 2 can now lend out £810 of the £900 to someone else, and keep the remaining £90 to add to its reserves (the 10% reserve requirement).
Again, the borrower spends it and the money goes to Bank 3.

This bank now has an asset of £810 and can lend £729 to someone else; and so on.
Bank 1 £1000 £100 £900
Bank 2 £900 £90 £810
Bank 3 £810 £81 £729
Bank 4 £729 £72.90 £656.10
Etc.... Totals ~£10,000 ~£1000 ~£9000

This can continue with ever-decreasing amounts, until eventually the original £1000 has allowed the banks between them to create another £9000.And the banks are charging interest on all of this new money. This has expanded the money supply by £9000.

So, the bank creates money. The bank ‘lends’ the money to society. The bank charges interest, just like the Goldsmiths did. The money that the bank created is eventually re-paid to the bank and is cancelled out of existence but there still remains a debt to be paid in the form of interest.

Let’s think about this for a moment.

Another Example
Let’s simplify the numbers and give an example of the underlying problem of the current system. We have 11 people in a closed room. 10 of them have nothing and the 11th has a bowl of beads. We’ll call the 11th person The Bank. The Bank now lends each person 10 beads for 1 hour and charges 10% interest on the loan. The people in the room are free to sell whatever they have to the other people in the room in exchange for beads. An hour passes.
Some people have now got the 11 beads they need to repay the Bank. This means that others don’t. It is obvious that there are not enough beads in the room for everyone to repay The Bank.

So, what can be done?
Well, some could ‘declare themselves bankrupt’ and hand over their assets to The Bank or, some people could take out further loans from The Bank. If The Bank allows these people to take out other loans that would ‘boost the economy’ and allow all of the people to repay their debts from the original round of lending. Of course, anyone who borrowed is now in further trouble. They must repay the new loan plus the interest.
As you can see, there are never enough beads in the room to repay The Bank. This growth of the money supply, along with the even greater growth of debt is the fundamental cause of the current ‘credit crunch’, because of the interest imposed on all this 'bank created' money.
Since the deregulation of the banks in the 1970s, the banks have been able to expand their money-creation greatly. They now have only tiny reserves, but huge profit from the interest they make on all the loans. This enriches them and their shareholders, at the expense of society.
The banking system has always been precarious, and is now far more so. With such small reserves to call on when customers withdraw their money it only takes a few ‘bad debts’ to be written off, or a few people to lose trust in the bank and to withdraw their money, for the bank to run into problems. Once news gets out that a bank is in trouble, others start withdrawing their money and the bank becomes bankrupt. With the ever-growing levels of debt due to the way the banks create our money by making loans, and the growing amount of interest to be paid on those loans, any slowing of ‘economic growth’ can threaten the whole banking system with collapse as the debts become un-repayable – which is why the authorities are now so desperate.
With ‘globalisation and deregulation’ since the 1970s, the banks have been heavily involved with international trade, and so the ‘credit crunch’ is affecting the whole world.

Software says oops to Mars Climate Orbiter '98


Since the dominance of computers in our life, people might think that software is the most perfect thing that has happened to mankind since it does many useful thing for us( yes hardware is definitely required, but its the software which drives and controls the hardware). We also might assume that software should never fail. But the truth is contrast to that belief. Software is prone to failure and the fact that there is 10000s of lines of code makes it more difficult to test thoroughly. Lets take a very simple example, how many time do you have to restart your computer or cellphone? Ideally that should not happen but it does happen.
I tried to search some of the biggest project failures due to software errors and came across the one which failed the mission to Mars (yes planet Mars). Obviously it was a human error which lead to the failure of software but it shows that how fail-able software is!

The Mars Climate Orbiter (formerly the Mars Surveyor '98 Orbiter) was one of two spacecraft in the Mars Surveyor '98 program. The two missions were to study the Martian weather, climate, and water and carbon dioxide budget, in order to understand the reservoirs, behavior, and atmospheric role of volatiles and to search for evidence of long-term and episodic climate changes.

The Mars Climate Orbiter was intended to enter orbit at an altitude of 140–150 km above Mars. However, a navigation error caused the spacecraft to reach as low as 57 km. The spacecraft was destroyed by atmospheric stresses and friction at this low altitude. The navigation error arose because a NASA subcontractor (Lockheed Martin) used Imperial units (pound-seconds) instead of the metric system. The software was used to control thrusters on the spacecraft which were intended to control its rate of rotation, but by using the wrong units, the ground station underestimated the effect of the thrusters by a factor of 4.45.This is the difference between a pound force - the imperial unit - and a newton, the metric unit. The software was working in pounds force, while the spacecraft expected figures in newtons - and 1 pound force equals approximately 4.45 newtons.The problem arose partly because the software had been adapted from use on the earlier Mars Climate Orbiter, without proper testing before launch, and partly because the navigation data provided by this software was not cross-checked while in flight.The Mars Climate Orbiter thus drifted off course during its voyage and entered a much lower orbit than planned, and was destroyed by atmospheric friction.

The total cost of the mission was $327.6 million ONLY.
Well there can be other argument as well, why do we have two different units of measurement? But I will not go into that side as it unrelated to software and related to HUMANS.

Cisco's ideas sharing concept- I-Prize


Cisco's innovation contest is one of at least a dozen corporate-sponsored competitions that have cropped up in recent years, all aimed at developing and rewarding innovation. Microsoft (MSFT), for instance, annually awards its $25,000 Imagine Cup to a student team that best uses technology to solve a real-world problem. Cisco tries to extend this concept in which the winning team may have the opportunity to be hired by Cisco to found a new business unit and share a $250,000 signing bonus. Cisco may also invest approximately $10 million over three years to staff, develop, and go to market with a new business based on your idea.
This an interesting way to move forward specially in current market full of competition. This might help Cisco to get a headstart into near future techonolgy,concept etc. Cisco's Telepresence is one of the outcome of this effort. Companies do have such portals which are used internally to the company but issue is that we can only submit the ideas related to the stuff the company works for. e.g If I am working in telecomunication company I cannot submit the idea on to how to improve the efficiency of a four-stroke engine since that would not be relevant to the companies road map. Cisco's i-prize gives that platform to register your idea and if they feel that it is persuable then (and provided that your ideas is voted the best) you have a bright future.

Following is some details on how to participate at Cisco's I-prize.

Register on the Cisco I-Prize Website. Post your idea and comment on other ideas posted by fellow entrepreneurs. Use the Human Network to refine your concept and form an idea team of all-stars that can take your idea to the next level.

Cisco will select up to 100 semifinalist teams that will work with Cisco experts using state-of-the-art collaboration tools to build a business plan and presentation. Next, up to 10 finalist teams will present to a judging panel for the ultimate prize: the opportunity to start a new business unit with access to the resources that Cisco has to offer.

Its definitely not easy task but if you genuinely think that you have the idea which could save the world or avoid next world war I-Prize might just be the place to start at.

Public Private Partnership

Recently I heard a podcast from Vanderbilt Owen Graduate School of Management. It had an interesting topic "Industrialization in Emerging Markets"। It was a 90 minute discussion but I am putting some interesting points which one of the presenters pointed to. With the theme as to how important is Industrialization in Emerging markets, emphasis was put in to how Public Private Partnership is must for this to happen. It was more of how one leads to the other. By the way Public here stands for local government, local non-profit organizations and Private means Multinational organizations like Microsoft, Coca Cola etc. From here onwards I am trying to put down the words of the presenter.

Why public private partnership is important for industrialization in emerging markets?
The issue which many multinational companies face right now is consistently finding new customer base in their current market and also finding resources/labor as cheap as possible since the competition is growing. Getting into emerging markets will help them to solve both the issues. Firstly they will have new customer base and also they will get access to cheaper labor and other resources and also improve their global image. The emerging markets also benefit since people get employment and Industrialization brings whole lot of other developments in the country.
But the companies are facing many business challenges in these emerging markets since they are going into countries like Chad, Somalia, Rwanda where they never thought they would be going. The challenges they face range from Human rights challenges to enterprise development , social challenges etc. and this is where the local government and organizations come into picture. The presenter gives two very good examples which pretty much explains everything about Public Private Partnership and why it works and make sense.

Coca Cola
Coca Cola sells products in 200 countries. It takes 3 liters of clean water to produce 1 liter of Coca Cola. By 2050 25% = 50 countries will not have clean water to produce coca cola. So one of the biggest challenges it has is how to conserve clean water so that after 2050 it can produce and sell there and around the world. The solution they have come with is to partner with the local governments to revise the policies on water usage, improve the efficiency of water usage, dig more wells in remote villages. They also have partnered with municipalities to build water cleaning plants at more places.

Star Bucks
Currently Starbucks faces a challenge to add variety in its coffee offerings. The solution they worked on is start growing coffee in Rwanda and import from there. Rwanda did not grow coffee before 5 years but with Starbucks and Rwanda government partnership now they grow and export coffee. This adds variety to Starbucks' coffee offerings and people in Rwanda get employment.

The reason I personally was impressed with the talk is that it seems now onwards big companies will have to consider emerging markets for cheaper labor and new customer base. Such symbiotic relationship will definitely help both entities here. I hope such efforts continue and I think they will until there are incentives for the companies to go into untapped markets.

Note: All credit about the information goes to the presenter of the talk.

Scan Gauge

Couple of months back I got a new toy, Scan Gauge. Basically this device connects to you car computer and provides you real time data about the mileage, rpm etc. It also does and little book keeping which would store data about the current day and yesterday (a day before). It will give you a Trip summary such as total mileage of the current trip, total time traveled, max speed etc and same for the previous day. It also gives you information about the error codes when you see some new lights turned around the odometer. If you see such lights often, this device will help to diagnose about the issues and might save you a trip to the mechanic. Its form factor make is very easy to fit even in a very small space. Connecting it and setup is very easy, just connect it with the car computer and you are good to go. It (car computer connection) is the same place at which the technician connects when you go for State inspection. Then start the car and set the size of the engine (e.g. 2L ,1.8L etc.) and the gas tank size. It might take up to a couple of tank fill-ups for the device to give near to accurate information. I have been using since couple of months and I see mileage data very close to the actual mileage I get. In near future I will try to post some data which I get from the scan gauge. To get more correct information about the device and its uses visit ScanGauge website.

WHY USE RECYCLED PAPERS?

All the time we have heard and read that using recycled paper helps to save trees and conserve energy, all in all is good for environment. This information which I got from a cover of printer paper ream by Aspen , which shows actually how much it helps the environment. Choosing recycled papers over non-recycled paper has following environmental impact*.

HOW MUCH CAN YOU SAVE - II

This post is in continuation with my previous post. I want to prove my point that with little consideration we can save electricity and contribute in the fight against the global warming. So let's take one more example. In my rest room I have 6 normal light bulbs to enlighten it, each bulb 60W. Let's say that I spend 1.5 hr every day in the restroom, so that would be 6*60=360Wh=.36kWh everyday. So for one month that would be 0.36*30 *1.5=16.2kWh every month => 16.2 * 0.22= $3.56 approx. I surely didn't needed all the six bulbs so I removed 3 of them and replaced the other 3 with 13W fluorescent bulb. 13W fluorescent is equivalent to 60W normal bulbs, so after these changes the saving would be= 3*13W=39W *1.5 hrs* 30 days = 1.755 kWh *.22= $0.39 approx So I save about $3.15 every month. So now justs adding the savings from previous post $4( by switching off the wireless router and cable modem) + $3.15 =$7.15 savings / month. Now the above scheme of bulbs there is a catch, you have to buy the fluorescent bulbs, but hey thats one time investment for at least 3-5 years. And also you are helping to avoid global warming. I will be posting some more examples, as I they come in my mind but surly currently we are abusing environment by relying more and more on non renewable sources of energy!! I hope after reading these posts a small thread would have spawn in your minds! Feel free to post your views or the changes which you made after reading my blog, sometimes feedback give motivation as well!!

HOW MUCH CAN YOU SAVE-I

I don't know how to start this but am trying to bring out one of the threads that has been running in my mind since long. Call me "Global warming" fanatic or "kanjoos" (you will know in a short while why am saying this), I am going to put down the thoughts and the research I did after that. Also this is not only just about me or my thoughts, the suggestions I have would help you to mitigate your rising electric bills to some extent. The use of electric/electronic devices in our life is so common that sometimes we even don't realize that we are using them. We need to burn fuel in order to generate electricity, and combustion of fuel leads to more green house gases in the atmosphere which leads to global warming. See its that simple!!
I have always been thinking as how much electricity would a given device consume in a given time? Lets say my TV is on but am not watching it, so what impact would this have on the environment? There are two parts to above questions a) how much electricity my TV consumes? b) what impact would this have on the environment?
First I will try to answer the first question.
I know that there is a very basic formula to calculate electic consumption of a given device, but me being a dumbo in Electrical stuff (e.g. it was tough for me to remember ohm's law) had to search it online and I came across this nice website by Michael which gives me all the necessary information.
Thanks to this website and its author, now I understand HOW MUCH ! electricity a given device consumes in a given time.I am putting down some interesting information but I encourage you to go through the site for more information if you are still reading this blog.
Usage of electricity is measured in kWh => kilo watt hour and we are billed according to that number. The formula to calculate kWh = (# watts usage per hour * # hours )/1000.
We are charged according to amount of electricity we use and the unit is kWh=>kilo watt hour. Nearly everything you can plug into the wall has a label that says how much electricity it uses i.e # of watts. (It may be printed directly into the plastic or metal.) You will have to make some efforts to find it.
If the label only gives the number of amps and not the number of watts, then just multiply the amps by 120 (for USA) to get the number of watts.
e.g. it the label says 65W, it means the device consumes 65Wh every hour.
if it says 5 amps, then it means the device uses 5*120 W hour every hour. (120 for USA and I think for India and European countries it is 240).
Now if you know how much you are charged per kWh then you can exactly calculate how much a the usage of a give device can cost you. Lets take an example so that I can help you take off some $s from you electric bill -;)
I have cable internet at my home, and I also use wireless router so that I can get internet in any room without need a physical connection between the computer/laptop and cable modem. For the sake of the study we will exclude the electricity consumption by the computer/laptop. Both the cable modem and the wireless router use electricity when they are turned on. My modem uses 18W and router uses 16W, so when I use them both, the total usage is 34W every hour. Lets say I don't switch them off during night (when we are not using it). Lets say we don't use internet from 11pm to 5 pm other day as we sleep at night and work till 5 pm. So in total 18hrs of non usage time. So the total kWh = 34*18 = 612/1000=0.612 kWh . In my last electric bill I saw that I am charged $0.22/kWh, so that totals 0.135 $ per day => $4 /month. So see now I am saving $4 every month just by switching off the modem and wireless router and you can too!.
Thats enough for now, will be adding more information soon as this post seems to have grown a bit big!!!!

Why do we still keep using Pennies and Nickel?

Soaring copper prices are pinching the penny makers. It now costs 1.3cents to make a penny and 7.7cents to make a nickel. But there's an environmental cost, too, to minting new coins- namely, copper mining and refining that involves huge amounts of power and water. Coinstar estimates there are some 150 billion coins going unused in US. => $10billion or $90 per household, stashed in mason jars and under couch cushions. Cashing in just 10% of this amount would translate into sizable environmental savings as show in the table below.

Savings OfEquivalent to
Water82 million showers*

World's cleanest car

With the increasing concern of global warming and the prices of gas (petrol) we are looking for other renewable sources of energy. Fuel combustion produces carbon dioxide which is a green house gas. More vehicles on the road means more carbon dioxide which in turn means more risk to global warming. What if we have a car which runs without gas or any other combustible fuel!
MDI is a company which has created an engine which works on compressed air. Well this is similar to the small rockets we used to create when we were kids. Blow air into the balloon and then let it loose. What happens? The air rushed out with a force which pushed the balloon forward. This is the principal which this car follows, except we don't have to fill up the air in the car.
Look at this link for more details, www.theaircar.com
Well the concept is interesting but this is even more interesting. When the compressed air is let loose it is cooler, and we can use this cool air to cool the car during summer. There are certain drawbacks here. The maximum speed this car runs is about 70 mph, so our F1 racers won't be able to drive this car. Also these cars need to be smaller in size due to capacity of the engine, so big SUV owners won't be interested in this car either.
But here is the main part, after fully charged, meaning after having tank full of compressed air, the car runs for 125 miles. It takes about 1.5 hours and costs about $2.5 to fill the tank with compressed air.
TATA from India is trying to bring this car in India by 2009. This car is being launched in Summer 2008 in France and other European countries. Just think about the future of this engine and the future of planet earth with this automobile running on similar engines.

QT Cross Platform Application Devleopment Framework

If you are looking to develop non-commercial applications with different platforms in mind, Qt (Qtopia) is surely worth a look. You can use for commercial applications as well if you buy a licensed version. It includes C++ class library(if you are C++ fan, its for you) and tools for cross-platform development and internationalization. Qt is also available for Java programmers. For more information you can go to Qt . They also have application platform for efficient creation of Linux-based devices. For more information go to Qtopia

HYPERMILING

Today, in newspaper I came across an interesting article about this guy Wayne Gerdes and his Hypermiling theory. In the theory he suggest/explains different ways to get better mileage than the EPA estimate for your car. For detailed explanation you can visit www.cleanmpg.com . He has some interesting ways by which we can increase the mileage of our car, and its not limited to hybrid cars. One of his accomplishments that were described in the paper were getting 57MPG in Honda Accord and 127MPG in Toyota prius. Not all the ways he describes on the website are totally safe but they are worth reading as they explain the forces which take away the MPG from our while we drive in our AC car totally oblivious of.
