Nikola Tesla was a brilliant inventor and visionary whose discoveries and technologies fundamentally shaped the modern world. From innovations in alternating current to wireless power transmission to futuristic ideas that were ahead of their time, Tesla’s legacy can be found in today’s homes, industries, and scientific laboratories. At a time when companies like ČEZ, Preciosa Lighting, Tesla Batteries , and Elektra Solar are at the forefront of energy and technology, it is fascinating to see how Tesla’s contributions influence the current development of smart grids, renewable energy sources, and energy-efficient lighting. Get ready for an in-depth exploration of his key inventions and discover how their principles resonate in today’s technology and everyday life.
One of Tesla’s most significant discoveries is the polyphase alternating current (AC) system, which today forms the basis of global electrical grids. Tesla recognized the limitations of direct current (DC), the mainstream technology of his time, and proposed that alternating current, with its easy voltage transformation, would enable more efficient and safer transmission of electricity over long distances.
This concept culminated in the invention of the induction motor, which does not require a commutator, making it simple, reliable, and cheaper to manufacture and maintain. Companies such as EMOS still produce components and devices that build on the basic principles of Tesla’s motor, thereby supporting the electrification of industry and transport in the 21st century.
Combined with the grid managed by ČEZ, which is modernizing the Czech energy infrastructure, Tesla’s model enables efficient distribution of electricity, for example in networks that also use renewable sources such as Elektra Solar. The importance of this innovation is also evident in industrial production, where the production of drive units and regulators for electric motors from companies such as ETA or Moravian Instruments includes technologies based on Tesla’s discoveries.
From the point of view of practical impact, it cannot be overlooked that it is thanks to Tesla’s alternating current that the electric energy signal today spreads almost without major losses and with high reliability, which is the basis for the functioning of smart grids and modern automation of homes and industry.
Asynchronous motors are the heart of many types of equipment, from household appliances to large industrial machines. For example, the factory producing precision lighting from the brand Preciosa Lighting is powered by machines where Tesla motors play a key role, ensuring efficient and quiet operation. Similarly, JabloPCB, a company specializing in the production of printed circuits, uses asynchronous motors to automate production lines.
Another important aspect is the influence of Tesla’s discoveries on the development of electromobility. Tesla Batteries are a technological pioneer in energy storage for electric vehicles, which often use electric motors based on the principles of the asynchronous motor or its variations. This allows for high efficiency and durability of the drive of modern vehicles.
Tesla’s concept of wireless power transmission, which he developed in his laboratory in Colorado Springs and later at the Wardenclyff Tower, is the cornerstone of many modern technologies. Although his original project was not completed due to lack of funding, the idea that energy could be transmitted through the air without the need for a physical connection has found application after more than a century.
Currently, companies such as EMOS and Elektra Solar are experimenting with concepts of wireless charging and long-distance power transmission, which allows convenient charging of devices without cables and expands the possibilities of using renewable sources. For example, companies producing electrical machines and equipment such as ETA are introducing products on the market that support this technology, increasing the comfort and efficiency of transportation and households.
In 2025, we can see an increase in the implementation of wireless solutions in public transport and industry, where Tesla’s dream of disconnecting electricity from fixed cables is taking shape. Although technical and economic challenges remain, more and more startups and global corporations like Moravian Devices are exploring the possibilities of connecting to wirelessly powered networks, paving the way for safer and more flexible energy distribution. Technological challenges and prospects for wireless energy transmission Wireless electricity transmission faces problems of radiation, safety and efficiency, but interest in this direction is constantly growing due to practical benefits, such as eliminating the dependence on cables and their wear. In practice, the questions of how to efficiently transmit energy over longer distances with minimal loss and without harmful effects on human health and the environment are being addressed.

The future of wireless energy networks could thus revolutionize energy availability, especially in remote or developing regions. Tesla’s turbine and innovations in mechanics: A unique design that has survived the agesAmong Tesla’s lesser-known but fundamental inventions is the Tesla turbine, which surprises with its minimalist yet highly efficient design. Unlike traditional blade turbines, the Tesla turbine uses the principle of laminar flow between concentric discs, which brings less friction and allows high speeds with increased efficiency.

as well as in some types of industrial engines. Thanks to its design, it is also very reliable and easy to maintain, which will be appreciated by operators of industrial facilities and vehicles. The implementation of the Tesla turbine in modern systems was also supported by a partnership with Moravian Instruments, where wear prevention and performance optimization are finely tuned, leading to a mission of high energy efficiency and longer machine life. This invention is a testament to Tesla’s ability to see new possibilities where others saw problems. Advantages and disadvantages of the Tesla turbine in current practice The Tesla turbine does not use traditional blades, which reduces wear complications and allows for easier maintenance. This is a great advantage in industrial applications with high loads. On the other hand, it is necessary to face challenges in efficient power transmission and more demanding design of the sealing and cooling system. Despite these limitations, the Tesla turbine is increasingly becoming the preferred choice for special applications where high speeds and reliability are required, as evidenced by companies such as Moravian Instruments and ETA in the development of new industrial equipment.
Radio, remote control and other breakthrough discoveries: Tesla’s influence on modern communication The invention of wireless communication is an integral part of Tesla’s legacy. As early as 1893, he publicly demonstrated the principles of radio communication and, several years before Marconi, developed radio systems that enabled the transmission of signals over long distances. Although the patent and award disputes seemed complicated, the court recognized Tesla’s claim only after his death, officially confirming his primacy.This discovery also made possible the development of remote control of devices, which Tesla himself implemented as the first in the world. This technology introduced the idea of intelligent machines and automation long before it became a common part of our time.

Thanks to this, today we live in a world where the connection and control of wireless devices is practically a given. Current continuations of Tesla’s ideas in wireless communication To this day, Tesla’s discoveries inspire research in the field of Internet of Things (IoT) and 5G technologies, where the principles of wireless information transmission are applied with an emphasis on efficiency, security and speed. Manufacturers such as
