What is claimed is: 1. An ultrasonic fog generator comprising: a container comprising therein an ultrasonic nebulizer and a liquid, said ultrasonic nebulizer operative to vibrate at very high frequencies and thereby break down the liquid into a fog comprising tiny vapor particles, said container having an exit opening for said fog to pass therethrough; a driver and a driving fluid, said driver being operative to cause said driving fluid to flow past the exit opening and draw out said fog through the exit opening without said driving fluid substantially entering said container, wherein said driver is positioned facing a closed rear face of said container and said exit opening is positioned on a front face of said container opposite said rear face, wherein said front face of said container comprises a wall extending from side faces of said container, and said exit opening is formed through said wall. 2. The ultrasonic fog generator according to claim 1, wherein said ultrasonic nebulizer vibrates in a frequency range of 1.5-2.5 MHz. 3. The ultrasonic fog generator according to claim 1, wherein said ultrasonic nebulizer is operative to break down the liquid into fog comprising tiny vapor particles of 1-50 microns in diameter. 4. The ultrasonic fog generator according to claim 1, wherein said driver uses positive pressure to drive the driving fluid past the exit opening and drive the fog out of the container. 5. The ultrasonic fog generator according to claim 1, wherein said container is sufficiently closed to prevent direct light from impinging on the liquid. 6. The ultrasonic fog generator according to claim 1, wherein said driving fluid flows from said driver over side faces of said container spanning an entire length of said container.
