New for November 2009. This page was split off from our efficiency page.
All energy-transforming processes must follow the First and Second Laws of Thermodynamics, which are summarized here, with pomp and circumstance of capitalized bold letters in a font that adds considerable gravitas:
The First Law of Thermodynamics:
Energy and matter are never created, they just move about. You never get something for nothing.
The Second Law of Thermodynamics
Energy is always somewhat wasted when it is transformed from one type to another, you can't even break even. Energy conversion is like playing cards in a casino, and entropy is the house handle, you dig? It's depressing when you think about it.
We'll leave the mathematical proofs of these Important Laws up to your friendly college professors.
Therefore, efficiency of 100% is never possible. No matter how loud that idiot coach screams, nothing ever "gives 110%". Next time you hear him make this remark, inform him that his poor understanding of basic tenets of physics is having a detrimental effect on the team. He'll thank you!
