Power without wires
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.
