If I am alone on an island, I need to have the following items with me: a satelite telephone, a GPS navigator, a box of matches, a knife, and a mirror.GPS navigator can be used to locate my position accurately.Satelite telephone can be used to call for help.Matches can be used to start a fire to keep me warm and safe.Knife can be used to crack the coconuts I find on the island for food and drink.Mirror can be used to signal to the rescue plane flying nearby looking for me. With these inventions, I might even enjoy the short holiday on this lonely island. |
