The present invention provides a power-generating and rotating road marker using a magnet, in which a magnet is inserted into a waste golf ball and light is emitted using power generated via the magnet, so that a vehicle driver can easily identify a road even at night, thereby enabling the vehicle driver to perform safe driving. In particular, the present invention provides a power-generating and rotating road marker using a magnet, in which a magnetic electrode unit is disposed in a waste golf ball, power generated by the magnetic electrode unit is supplied to a light emission unit, and the light emission unit is allowed to flicker, so that an effect arises in that a vehicle driver can easily identify the flickering light emission unit and thus perform safe driving even at night, thereby preventing a traffic accident from occurring.

A collapsible runway side barrier for preventing foreign object debris (FOD) from entering a runway and taxiway. The barrier may have an aerodynamic profile, one side of the barrier profile may be convex and the other side of the barrier profile may be concave. The side barrier may further have ground attachment elements and may be constructed to collapse if the landing wheels of an aircraft impact the barrier.
