Creating a mini sun on the earth: ITER

Of all kinds of energies, the heat energy is most disorganised. This is because heat energy is the reflection of speeds and collisions of the atoms. Third law of thermodynamics states that entropy of universe is always increasing. Since entropy of a system is the measure of randomness or chaos, this means all kinds of energies when used for doing useful work waste a part in the form of heat energy. Most of the stars are made of hydrogen. It is the fuel that they burn everyday to produced light and heat. Hydrogen atoms exist in 3 forms called isotopes… Read More »Creating a mini sun on the earth: ITER
