Free energy tremor LED Designed by Margot Krasojevi ć Architects, the free energy tremor LED consists of a 3D printed net whose recycled polymer geometry is elastic yet strong enough to stretch and reform when subjected to tremors and shifting changes in its immediate environment. Because of the dome shape which channels the light around the surface of the semi-transparent ge- ometry, the net is designed to give the illusion of intensifying the emitted light. The project was commissioned for the Gao family hotels in Ordos, Inner Mongolia and Beijing. The main body of the light acts as a moveable piston intensified by the harmonic oscillating motion of the weighted 3D printed net as it stretches and expands. When charged, the LED is a bright 60-candela white light visible for three metres in a darkened room. A main structural thread pipe is at the core of the LED – this can be inserted into the ground for stability. The threaded pipe holds a series of magnets and a copper coil used to induce an electric current.The 3D printed net resonates and amplifies kinetic energy, transforming it into electrical current that lights the series of LEDs embedded within the geometry: the principle behind this is electromagnetic induction. All reverberations within the vicinity of the light induce a current by moving the magnets through the copper coil placed within the main structural thread pipe. The net’s spiral envelope is constructed from a flexible recycled polymer whose geometry intensifies its displacement, moving the magnets inside the supporting thread pipe to create a current that can either be stored or dissipated immediately by lighting the LED. The light is being adapted so that the inner surface of the 3D printed net is coated with copper. This will strengthen the magnetic field causing it to induce a higher and more constant electric current that lights the LED. Also under consideration is the application of a piezoelectric zinc element to produce a current strong enough to light a 9 V LED.
