From Farm to Art

From Farm to Art: The older a piece of metal is, the more Sherry Day seems to like it, although she doesn’t discriminate. This Union metal artist takes anything, never knowing what will inspire her next creation.

Iran invents circular magnet to clear streets of metal debris

Iran invents circular magnet to clear streets of metal debris



The device can efficiently remove 1 tonne of large or small
quantities of dangerous scrap metal from machining areas and shop
floors, can connect to the cars as tows and quickly clear metal debris from
streets, construction sites, runways, or steel mills, and operates over
wet or dry, smooth or unpaved surfaces.



Brilliant idea :-)
