Power is the rate at which energy is generated or consumed and hence is measured in units ( Watts) that represent energy per unit time. The amount of energy generated or consumed over a given period of time is equal to the average power times the duration. A Watt-second is a unit of energy, equal to one Joule: 1 Watt-second (W*s or Ws) = 1 Joule (J) 1 Watt (W) = 1 Joule per

 · Coal has too much sulphur in it for forgework. Now charcoal and pure sulfer mixed with one other ingredient makes black powder, it is all about energy that is going to be released. One is quicker than the other but the total amount of energy is the same, even wood can be explosive, aka a very
