Smoke comes from a fire at it's base. Hot air rises so the smoke is carried upward by the heated air
The smoke particles from a fire are carried up by hot air. Hot air has the tendency to rise because it has less density than normal air.
Smoke detectors detect smoke by not detecting it. They sense not the smoke, but the oxygen levels surrounding it. when the oxygen levels drop, or when smoke replaces the oxygen, the alarm goes off.
smoke is not energy ... it is that smoke particles take way heat from the origin(cigar or something )...

a smoke signal can help people spot you in the woods.
The smoke signal was invented in 1785 as it was a good way of communicating without other people knowing what you are doing.
Indians used smoke to communicate from a distance. Also smoke signals are used to signal aircraft landing points, and people in distress, To make a smoke signal: Make a small fire, Addfresh greenery to the fire (leaves), and leave the amount of smoke generated because of the greenery will create enough of a signal to attract the attention of any person with any knowledge about survival skills.
The Production Budget for Smoke Signals was $2,000,000.

The signal fire in the mountain was abandoned because the boys responsible for tending it got carried away and let the fire grow out of control, causing a forest fire. This incident led to a division among the boys and a loss of focus on their goal of being rescued.

The boys looked for their own smoke to signal the ship but it had gone out.
Yes. Since the signal is beamed from space, anything in the path of it, even smoke/heavy cloud cover, can cause interference.
