Sorry for the missing "Subject" on my previous message
If one places a brush on a flat surface and vibrates that surface, it will move on the direction that is controlled by the position of the bristles when on the air. I am designing a replacement for a "snow blower" that will pack the snow on my drive way, rather then moving it away.
20 centimeters of snow, when compacted,will result in about 2 centimeters of ice. At the end of the snow season I will have a 2+ centimeters of ice that will be melted by the Spring Sun.Irregularities on the accumulation of the snow will result on a surface that will be far from flat but will it be good enough to allow a car to be driven and parked over it?
