"The daily influx of meteorites and meteor dust is well known to scientists, but the total volume of mass daily added to Earth's surface is difficult to estimate and is not well documented. Estimates of total volume published by NASA vary widely (or wildly?) just for dust alone, ranging from as little as 1,000 tons/day (300,000 metric tons/yr, Dubin and McCracken, 1962) to 55,000 tons/day (20,000,000 tons/yr, Fiocco and Colombo, 1964). However, a more recent estimate puts the accreting dust volume at approximately 78,000 tons/yr, or 214 tons/day." http://www.expanding-earth.org/page_10.htm > The sources I've seen all seem to agree that common household dust is > mostly comprised of dead skin cells, dust mites and their dried feces, > and bits of fiber from fabrics. No mention of iron bearing asteroids. Funny they would overlook that - anyway, I *did* say it depends on the dust.

So, it is "most household dust" now, and not just "dust"? Okay, we agree "magnetism does not attract most household dust". Industrial environments would be another matter. Satellite equipment engineers might not need to worry too much about skin cells accumulating.

Ahhhh... well just be careful when air cleaning. Put a tooth pick in the fan grill to hold the fan before air cleaning. -- K Klement Enhance your marketing at http://www.gypsy-designs.com mailto:info(a)gypsy-designs.com Gypsy Designs Fax: (403) 242-3221 ....
