A revolutionary device that transmits electricity through window glass has been created in California
The Power Mole transmits 10 watts of electricity wirelessly through the window pane, allowing internal outlets to power external devices. It is based on inductive communication technology used in wireless smartphone charging systems.
Power Mole was created by California-based inventor Peter Bevelacqua. It is designed for situations where devices such as video surveillance cameras or lamps need a power source, but there are no external outlets nearby.
The system consists of two washer-shaped components: a transmitter attached to the inside of the window pane and a receiver attached to the outside of the glass. The transmitter plugs into an indoor home outlet and the receiver connects via a USB cable to an external device.
How does it work?
When alternating current passes through the induction coil of the transmitter, an alternating magnetic field is generated. This field passes through glass up to 30 mm thick, creating an alternating electric current in the induction coil of the receiver. The built-in rectifier converts AC power to DC power, which powers the connected gadget.
In its current form, Power Mole can only be used with devices that use a USB or 5V input. The developer reports that for powering a device such as a camera that consumes about 5 watts, the Power Mole’s efficiency ranges from about 50% (at a maximum distance of 30 mm) to 75% (at a distance of less than 6 mm).
However, if the transmitter is connected to the network but cannot connect to the receiver, it automatically turns off to save power. The system is also not limited to glass, as it can transmit a signal through wood or any other non-metallic material. If metal is detected between the transmitter and the receiver, the transmitter turns off.
