Rs 45 / 100km ... Mini CAT , Thats what a car should be.

It has been a long dream to come up with an alternate fuel that doesn't finishes overtime like fossils. Once over with Hydrogen that couldn't make it to commercial availability , one of the most abundant element (air) was tried over from many a years. Success came at hand when automobiles were made that run on compressed air (One of them at IIT Delhi) but none could go commercial. The reason being a single run gives you a ride of 30-40 kms and that the cost was too high to bear by a common man.

Now Tata Motors huge business have signed an agreement with the Moteur Development International of France to develop a car that runs on compressed air. Although the commercial production start date is still not confirmed , but is expected to come soonest possible in India. All thanks to Mr.Guy Nègre, the inventor.

The Mini CAT as named by the company, is expected to cost around 3.5 lacs and can run 300km at a single stretch before a refuel. Whats more amazing is the refueling cost, i.e. 90 Rs

Important features of the car

* Maximum speed : 220 kmph .
* Fibreglass bodies which makes them light, silent car . Tubular in design uses aerospace technology.
* a small computer screen that shows the speed and engine revolutions. The system allows for possibilities such as GSM telephone systems, GPS satellite tracking systems, programs for delivery people, emergency systems, internet connections, voice recognitions, map presentation, traffic information, etc.
* Both parts of the seat belts are anchored to the floor for avoiding damage to humans during collisions.
* MDI has bought a patent that is bound to reduce the important of electrical systems in all cars. The trick consists in using a small radio signal. The system makes the car 20 kilos lighter and considerably quieter.
* There are no keys - just an access card that can be read by the car from your pocket.
* In the single energy mode MDI cars consume around Rs 45 every 100 km .
* When there is no combustion, there is no pollution. The vehicle's driving range is close to twice that of the most advanced electric cars (from 200 to 300 km or 8 hours of circulation).
* The recharging of the car will be done at gas stations, once the market is developed. To fill the tanks it will take about to 2 to 3 minutes at a price of Rs 90. After refilling the car will be ready to driver 200 kms.
* The car also has a small compressor that can be connected to an electrical network (220V or 380V) and will recharged the tanks completely in 3 or 4 hours.
* Because the engine does not burn any fuel the car's oil (a litre of vegetable) only needs to be changed every 50,000 km .
* The temperature of the clean air expelled form the exhaust pipe is between 0 and 15 degrees below zero and can be subsequently channeled and used for air conditioning in the interior of the car.

Now thats what i am waiting for after the iPhone !!

Prescence of Mind

1. A person was sentenced death by some court of law, that has a very peculiar way of doing justice. After the person is being sentenced to death he is given a chance on the basis of his luck. The way is by choosing a slip from two, on which its written either Life or Death. The chosen slip gives him whats written within it. It so happens that some of his enemy changes the slip with script LIFE with another slip with DEATH. Now that very person knows about it. He did something to avoid that certain death and succeeded. What could he had done??
He swallowed the slip he chose. Now when the other slip was checked it contained DEATH so the executor will no doubt suppose the slip he swallowed contained LIFE.

Going about the logic, as he knows that both the slips contain DEATH for him, if he somehow finds a way that the slip he chooses is determined by the other remaining slip without opening the slip he has chosen. Then as the other slip contains death , the slip he has will certainly contain LIFE as conceived by others. So he can be set free.

2. Why is it better to have round manhole covers compared to square manhole covers?
A square manhole cover can fall into the cover through the diagnol , as the diagnol length is greater than the sides. But a round manhole cover can never fall into the manhole

3. You want to send a valuable object to a friend securely. You have a box which can be fitted with multiple locks. However, your friend does not have any keys to your locks, and if you send a key ,there is a danger of theft. How can you send the object securely?
Put the valuable in the box, lock it, send it across to your friend. Tell the friend to lock it over again with his lock and send back to you. When you receive it back , remove your lock and send it back to him.

4. If you put a coin in an empty bottle and insert a cork into the neck of the bottle, how could you remove the coin without taking the cork out or breaking the bottle?
Hahahaha.... Push the cork inside the bottle and now take the coin out.

Mathematics + English = 4

Found by Martin Gardner about the what the combination of mathematics and English will lead to.
There is an interesting fact about the english translation of the numbers. The number of characters in the english translation of any number leads to the number FOUR , from where you cannot go anywhere. Now follow the following little steps to know the wonder:

1. Choose any number and convert it to its English counterpart.
2. Count the number of characters in it including spaces , hyphens.
3. Take the new number and follow again follow steps 1 and 2.

You will finally reach the number FOUR which have the number of characters as 4 and now from here you cannot move forward.

Lets take 225
225 -- Two hundred and twenty Five -- Number of characters : 27
27 --- Twenty Seven -- Number of characters : 12
12 --- Twelve -- Number of characters : 6
6 ---- Six -- 3
3 ---- Three -- 5
5 ---- Five --4
4 ---- Four -- 4
4 ---- Four -- 4
4 ---- Four -- 4

Nowhere to go now.

Right way to heaven

After a person's death , he is heading towards heaven. On his way he finds a the path is now divided into two different paths. He wants to reach heaven and suddenly finds there are three persons sitting at a place. He came to know that the three people are Gandhi, Hitler and Goebbels but dont know who is who. The three people will answer only 2 questions that can be directed to any of them. Now the dead man knows Gandhi always speaks truth , Hitler always tells a lie and Goebbels tells whatever he wants. If you were to ask those 2 questions , how will you go on asking what questions that can tell you the correct way to the heaven.

How to go about it?(Hint)
Here first we need to remove the most vague and dangerous part of the puzzle i.e the Goebbels , who can tell anything a lie or a truth. So the first question must eliminate this guy for sure.

Now that we know the remaining two persons either always tell a lie or always tell a truth. The truth speaking person will always tell the correct way. Now the problem lies in the fact that you dont know whether the person you are asking is telling a lie or a truth. Making the use of always lying behaviour you must frame the second question in such a way that it negates itself twice and returns back to the correct answer.

Having being through with the strategy now lets go for the problem

Eliminate Goebbels ---> Question to ask anyone . Is A more honest than B?? If he answers Yes then ask B or else ask A the next question
Scenario 1a: Person is Gandhi , A : Goebbels , B: Hitler
Answer : Yes
Next question to : B

Scenario 1b: Person is Gandhi , A : Hitler , B:Goebbels
Answer : No
Next question to : A

Scenario 2a: Person is Hitler , A : Goebbels , B: Gandhi
Answer : Yes
Next question to : B

Scenario 2a: Person is Hitler , A : Gandhi, B: Goebbels
Answer : No
Next question to : A

Scenario : Person is Goebbels , A : Hitler , B: Gandhi
Answer : Yes / No
Next question to : B (We have already eliminated Goebbels , as we asked the question from him only)

Next Question: Am i correct to assume , when i ask you whether the way to heaven is to the left , you will respond Yes??
Now if he is Gandhi he will tell the correct way. and if Hitler he will negate the question twice to give the correct answer. First that heaven it to the left , he will try to say no its to the right. Then he will negate again and say you assume right!
