A vehicle traveling through an environmental media such as air experiences drag. The drag is actively modulated by energy beams which may either increase or decrease the drag. The energy beams may provide either a chemical, acoustic or electromagnetic energy at a transition region between turbulent and laminar flows or at the leading edge of a laminar flow or in the direction of a crosswind in order to facilitate the respective increase or decrease in drag. Where the energy beams are acoustic or ultrasonic, some or all of the beams may be used to generate an audible signal, in a directional manner, outside the vehicle.

What is claimed: 1. A device for communicating, including: means for combining an ultrasonic signal with an audio signal; and, means for transmitting said combined ultrasonic signal from a first moving vehicle to a second moving vehicle; wherein said audio signal is audible within said second movin
What is claimed: 1. A device for communicating, including: means for combining an ultrasonic signal with an audio signal; and, means for transmitting said combined ultrasonic signal from a first moving vehicle to a second moving vehicle; wherein said audio signal is audible within said second moving vehicle. 2. The device of claim 1, further including means cooperative with a second vehicle for separating said audio signal from said ultrasonic signal. 3. The device of claim 1, wherein said means for separating includes glass. 4. The device of claim 1, wherein said means for combining include a parametric array. 5. The device of claim 1, wherein said means for combining include a modulator. 6. The device of claim 1, wherein said audio signal includes at least one spoken word. 7. The device of claim 1, wherein said audio signal indicates an alert to said second vehicle. 8. The device of claim 7, wherein said audio signal indicates said first vehicle is decelerating. 9. The device of claim 1, wherein when said first vehicle is decelerating, said transmitting is directed rearward to said second vehicle. 10. The device of claim 1, further including a microphone in said first vehicle, wherein said audio signal includes input from said microphone. 11. The device of claim 1, wherein said means for combining and transmitting are provided in said first and said second vehicles, enabling a conversation. 12. The device of claim 1, further comprising a horn switch, wherein said audio signal is operative to represent a horn. 13. A method for communicating between at least two vehicles, including: generating an audio signal; combining said audio signal with an ultrasonic signal; transmitting said combined signal from a first vehicle to at least one other vehicle in a particular direction; wherein said audio signal is heard within said at least one other vehicle. 14. The method of claim 13, further including the step of directing said ultrasonic signal into a transitional section between a laminar flow and a turbulent flow of a boundary layer adjacent to a surface of said first vehicle. 15. The method of claim 13, further comprising the step of selecting an audio signal and a direction of transmission based on whether said first vehicle is accelerating, decelerating, or braking. 16. The method of claim 13, wherein at least two vehicles generate, combine, and transmit, wherein at least two way communication is enabled. 17. The method of claim 16, wherein said step of generating includes using a microphone. 18. A method for modifying drag and communicating between at least two vehicles, including: generating an audio signal; generating an ultrasonic signal using at least one transducer; directing said ultrasonic signal into a transitional section between a laminar flow and a turbulent flow of a boundary layer adjacent to a surface of a first vehicle; combining said ultrasonic signal with said audio signal; transmitting said combined signal from said first vehicle to at least one other vehicle; wherein said audio signal is audible within said at least one other vehicle. 19. The method of claim 18, further including the steps of: locating at least one transducer in a location where said combined ultrasonic signal strikes said transitional section, and reflects from the vehicle body. 20. The method of claim 18, further including the steps of: in said step of generating, using at least two transducers; and, selectively combining said audio signal with less than all of said transducers.
