A system for wireless power transmission comprising: (i) a transmitter comprising a laser beam generator, said transmitter adapted to transmit said wireless power to at least one receiver configured to convert said laser beam into electrical power, said at least one receiver having a receiver control unit and a receiver control unit malfunction detection system associated therewith, said transmitter having at least two states, including at least one known safe state, said at least one receiver control unit malfunction detection system configured to cause said transmitter to switch to at least one of said safe states upon detection of a receiver control unit malfunction; (ii) a hazard detection system configured to detect the probability that human-accessible emission levels from said wireless power transmission system exceed a predetermined threshold, and if said probability exceeds a probability threshold, to cause said transmitter to switch to at least one of said safe states; (iii) a system control unit; and (iv) at least one system control unit malfunction detection system configured to cause said transmitter to switch to at least one of said safe states upon detection of at least one of a system control unit malfunction or a receiver control unit malfunction; wherein said system control unit is adapted to: (a) store data relevant to the operation of said system, from a plurality of sensors adapted to obtain said data, at least one of said sensors being associated with at least one of said receivers; (b) compare at least a portion of said data from said plurality of sensors with at least one previously known signature, said signature associated with a non-critical event and with an increased probability of one or more potential unwanted situations, and (c) execute one or more responses based on the result of said comparison, initiation of said one or more responses occurring only during a time when said hazard detection system is not causing said transmitter to switch to any of said safe states, said responses configured to achieve at least one of: reducing the probability of occurrence of one or more of said potential unwanted situations; reducing the effect of one or more of said potential unwanted situations, and facilitating successful recovery from one or more of said potential unwanted situations.
