    • Facing an energetic crisis, the only way forward is to globally economise the usage of fuel, some cities are already using this system that only lights up when a person is nearby.

    A very clever way to illuminate the city / 

    The planet’s energetic consumption is rapidly increasing due to the growth of the global population. And even if the panorama seems catastrophic, technological developments can help us avoid overexploiting our resources. This is what Chintah Shah, owner of the Dutch company, Tvilight, thought.

    Streetlights are one of the most important consumers of electric energy; urban growth demands that services simultaneously cover massive usage in the domestic and public spheres. In this sense, while Shan was travelling by airplane, he noticed that many urban spots remained lit at night, even if the areas were actually empty. Inspired by the energy that was clearly being wasted; he created a sporadic illumination system, which saves up to 80% of the total electricity used.

    His electrical lighting scheme, named Tvilight System, uses sensors that communicate with each other when a human movement is detected. This type of technology would have been completely impossible only five years ago. This is a different system to already existing sensors, because these have chain reactions that notify others, calculating distances and the required time for the light to turn on in order to illuminate a person’s path.

    Solely in Europe, 10 billion Euros are spent on the illumination of public spaces every year, a number which in addition to being exorbitant reflects the vast amounts of energy required. This has made Shah’s invention all the more attractive for governments that are seeking eco-friendly solutions. Since the year 2011, when the first Tvilight System was installed, hundreds more have been incorporated in countries like Germany. Holland is already home to an entire city that relies exclusively on this system.

    Among the clever solutions provided by the system, the activation of red lights from a distance great enough for heavy cargo transports to be able to stop when there is a similar type vehicle nearby, is essential. Additionally, the lights never turn off completely, and they always remain with a 30% glow, which means all places are visible, even at night.

    Funnily enough, the Dutchman was also inspired by Michael Jackson’s concerts, since the lighting system around him worked in coordination with the movements of the artist and the music, creating a circle of light, where each sensor informed the next of of the movement’s direction.

    As an example of a fortunate relationship between sensibility, creativity and rentability, Tvilight combines technology, business and the planet’s health, which now are, perhaps, more compatible than ever.
