Of course the conservation of mass/energy forbids the creation / destroying of energy in a closed system.
From the efficiency point of view there is a loss of energy involved in the change of energy from one form to another.
Maji yakibadilika kwenda barafu inabidi energy itumike, ndo maana friji linatumia umeme.
Mbao ikibadilika kuwa majivu moto unatumika.Energy nyingine ina escape kuwa gases etc. So you cannot contain this process and make it perfect.
This is why you cannot have a self perpetuating machine.
Bado huwezi kuwa na a perfectly efficient system, mtu yeyote mwenye knowledge ndogo tu ya physics anajua hilo.
Ni sawa, uko sawa
