Welcome to the Age of Wireless Electricity By Rupendra Brahambhatt
Joonas kääriäinen/pexels WIRELESS ELECTRICITY IS A 100-year-old dream that just might turn into reality in the coming years. The advent of wireless charging, electric vehicles, 5G, and the need for greater sustainability have led to a push for the development of fully operational wireless transmission technology in different parts of the world. From America's Wave Inc. to Japan-based Space Power Technologies and New Zealand’s energy startup Emrod, there are a number of companies that are currently working on wireless power transmission technology. Field tests have also begun for some systems, and it will be interesting to see who comes first in this race to offer an efficient, economical, and viable wireless electricity solution.
makes it a reliable choice for future power needs. In the year 1891, Serbian-American inventor Nikola Tesla designed the Tesla coil, a unique device that worked on the principle of electrical resonance, and was able to transmit electricity without wires. However, the coil could conduct electricity wirelessly over short distances only, and due to its limited potential, it didn’t turn out to be a practical application for wireless electricity transfer. Tesla was still obsessed with his idea of wireless power, so in the years that followed he worked on building an energy station that could conduct high-voltage wireless power transmission (WPT). Through this experimentation, Tesla aimed to transmit messages wirelessly at long distances, using either a series of strategically positioned The history and science behind towers or a system of suspended balloons. wireless power transmission (WPT) He constructed a wireless transmission station Before we get into the different revolutionary in Long Island (called the Tesla or Wardenclyffe initiatives concerning wireless electricity, it Tower) which he believed could demonstrate that is important to understand its origin and the underlying concept behind this technology that see page 90
