Interested parties would like to track the location of one or more towed transport platforms continuously when they are in motion. Existing monitoring systems are powered by a combination of solar power, batteries, and intermittent tractor platform power for electrical power. All of these power sources have limitations in providing power when a towed transport platform is in motion. Solar power is not available at night. Batteries run out of energy and must be recharged. Tractor platform power is not always available to a towed transport platform. The embodiments of the invention convert the kinetic energy of a moving towed transport platform into electrical power, providing continuous power for a monitoring system to operate.

Described hereafter is a device for the conversion of electromagnetic momentum into mechanical momentum to be used in airless environment. The device is built from rotating disk, made of non-magnetic material, on the circumference of which plurality of bar magnets are mounted. The bar magnets are in a plane which is perpendicular to the plane of the disk and in a plane, which is perpendicular to the radius of the disk that meets the centre of the bar magnet. The disk is driven by a motor that causes it to rotate. The magnets are positioned in an angle relative to the rotation axis of the disk. When the disk rotates, mechanical momentum, perpendicular to the plane of the rotating disk is generated. This momentum acts on the disk and causes it to move along the axis of rotation of the disk.
