<p>The method involves filling a bag with sand in a fire station, where the bag is fabricated from three different pieces in which two of the pieces are made of tarpaulin and the third piece is made of net. The two pieces are attached with a round PVC rod such that a firefighter pulls the rod to allow a helicopter or a tug to lift the bag for pouring sand through the net to form a separation space in a burning forest. The space is enabled to completely control the fire even in case of changing of wind direction, such that a green space in the forest converts carbon dioxide into preserved oxygen. An independent claim is also included for a helicopter comprising a tree cutting or displacing system.</p> |
