Our innovation converts sound energy released by man-made processes into useful electrical energy. When placed near airport runways, highways or railways, our device can consistently produce electrical energy in order to power various electrical appliances.

Our innovation is a novel application of established, but publicly available technology, consists of two concrete acoustic mirrors and a box-shaped converter.

The converter has a large circular elastic membrane on each side and an internal mechanism that converts the movement of the membranes into electrical energy. The elliptic acoustic mirrors focus sound waves from different sources toward the membranes of the converter. The membrane will absorb approximately 25% of the energy carried by sound waves upon impact. The membranes are made of synthetic rubber which is durable and flexible. A ferrite magnet is connected to the membrane by a lightweight aluminum rod, and surrounded by the induction coil. The magnet is held above an aluminum rail attached to the ground, which means the membranes will not need to hold it up. As aluminum is non-magnetic, it will not interfere with the process.

The membrane is moved by the sound, moving the magnet and generating electromagnetic force. When sound waves reflect from the membrane, they reflect from the acoustic mirror in front of the converter to another one which will be more parabolic compared to the first mirror, placed behind the converter. Sound from the second mirror will be reflected to the opposite membrane which will be connected to the magnet, to which the first membrane is connected. The sound waves are reflected from the smaller acoustic mirror to the larger mirror and repeat the cycle. This creates repeating vibrations of the magnet, causing an echo effect, until the sound waves will fade out.

The generated electricity can then be stored in a large battery, in our case a repurposed car battery, and then can be used by whatever source that it is connected to. Having a battery ensures that electricity is sent at a consistent rate and is not wasted, as the direct production of electricity by the membrane would be erratic due to the randomness of the source of sound.

The device has a relatively small profile, especially when compared to contemporary renewable energy generators. The generator measures 1.4 meters tall and width, and about 2.5 meters long. The acoustic mirrors have a larger front profile, but are not quite long, with the larger one having a diameter of 1.5 meters and the smaller one having a diameter of 1 meter. The acoustic mirrors and the device together weigh roughly under 2 tons in total. This makes transporation and installation quite simple, without any need for a specially designated area for the device.

The benefits of this device include it's portability in comparision to renewable energy plants through the relavtively small size and mass of all components. It effectuates a smoother transition to fully renewable by lessening the dependence and allowing for the device to power certain sectors. The device also fosters oppurtunities to conduct more research on the implication of sound energy allowing for further advancement in harnessing sound to generate electrical energy. In-addition, the potential for improvement is broad, as it relatively new yet with more research the features of the device can become more efficient. such the membrane where adjustments can be made to capture 90-100% of all surrounding sound. While also leaving room for customization when made at a larger scale.
