someone designed an air conditioner that takes 500J of thermal energy from a cold room and exhausts 500J of thermal energy into the outside air. The energy is conserved, so the system should work. Is such a system feasible or are we optimistic about this new design. Why or why not?

where is the sun’s light enery going once the sun has set?
where is the light going when we switch off the torch facing an object. if light gets reflected how long it will do so. and if it gets absorbed, then will it add to the potential energy of the object that is facing the torch?
Is there any cycle (like hydrocycle)to prove that energy can neither be created nor be destroyed?
