  • Animal warning device
    Patent number: 8093994
    Abstract: An animal warning device for emitting a sound that is loud and consistent enough to cause animals to avoid oncoming vehicles. The present invention accomplishes this objective by electrically connecting a speaker to a wind-powered generator. The wind-powered generator is driven by air current striking an impeller. The device is mounted onto a vehicle such that oncoming air current strikes the impeller causing the impeller to rotate. Rotation of the impeller causes the generator to produce a current which powers the speaker. As such, it is unnecessary to connect the animal warning device to an external power source, such as the vehicle's alternator or battery.
