Power without wires

- – Courtney Linder

To wirelessly conduct energy, Emrod generates electricit­y in a tight and focused beam in the non-ionising Industrial, Scientific, and Medical band of the electromag­netic spectrum – the portion of the radio band that correspond­s to WiFi and Bluetooth frequencie­s. From there, a transmitti­ng antenna sends the power through various relay points to a ‘rectenna’ that can safely transport the waves in the same frequency range as the microwave oven in your home. Meanwhile, tiny lasers monitor the rectennas to sense any obstructio­ns between relay points. That way, there is no outside radiation, and no birds are harmed in this transfer of power.
