  1. Using Hydrogen as a liquid releases more energy on combustion then when it is at gaseous state. But then you would need containers to hold fuel with 20 Kelvin range for Hydrogen to be in liquid state. Now making a fuel tank that can remain at 20 K is cost consuming.
  2. It is an Electro Magnetic Pulse emitter. Most of these are banned and can harm any electronic equipments with the radius of the EMP device. Mostly the radius remains within 2-3 feet. Bring a mobile phone near it when the EMP device is on, and POOF goes your phone.
  3. Well actually, when water ( H2O ) undergoes electrolysis they get split into OH- ions and H+. Now at cathode ( Cathode is the negatively charged platinum electrode ) : H+ will gain one electron and will become H. Now this H again combines with another H and finally becomes H2 molecule. At anode ( Anode is the positively charged platinum electrode ) : The OH- ion will lose one electron. Thus 4OH will give 2 molecules of H2O and one molecule of O2. For better understanding look at the following equation below. At cathode : H+ + e- --> H H + H --> H2 At cathode : OH- --> OH + e- 4OH --> 2H2O + O2 Complete equation : 2H2O --(electrolysis)--> 2H2 + O2 I hope this helped you.
  4. Well Thanks guys, I appretiate your answers. But still there are scopes for developing hydrogen fuel. Thats why I got the interest. Anyway I came to know that explosion of hydrogen produces about 25 Joules per liter. I wonder how that can become an alternative to CNG and other hydrocarbons because CNG produces about 2500 Joules per liter. Gosh! We are running out of alternatives.
  5. Maybe you are using the same variable again and again. For Exmaple : sum=sum+i; Now here if sum is not declared as int sum=0; then junk value of sum will be printed instead of the actual value. Try print an integer variable without assigning any value to it ; you will get some junk value printed. I guess this maybe your problem.
  6. I have the same problem. You actually write programs that deals with numbers just to understand a concept in C++ programming. But neither you not I will be able to figure out where we will use our programming language untill and unless we get into a job that has to deal with C++. Actually you need to know how to link C++ with Access Database so as to write some program that has its own use.
  7. Hello readers, I was just wondering that Hydrogen in di-atomic state has its capability to explode when lighted with a spark. So in that case what is the amount of Force that is exerted by the explosion of Hydrogen? Does explosion of Hydrogen produce smoke? In that case what if the explosion is to take place with a lot of Oxygen supplied? Please help me answer this and clear my doubts. Thanks in advance.
