In an era where urbanisation is rapidly expanding, the challenge of efficiently delivering power to vast metropolitan areas remains pressing. Traditional wired infrastructure is often expensive, cumbersome, and prone to wear and tear, which leads to frequent maintenance and disruptions. Power beaming, or Long-range wireless energy transmission offers a revolutionary solution to these persistent problems by eliminating the need for physical connections.
The system is composed of a transmitting antenna, relay panels, and a rectifying antenna made of metamaterials that convert electromagnetic energy into direct current. The energy is projected point-to-point into long-wave frequency beams. Such beams allow the energy to travel from transmitter to transmitter so it does not disperse or radiate where it is not channelled.
As cabled energy systems have expensive and time-consuming installation and maintenance costs, a wireless power infrastructure offers a more economically viable option. Power Beaming can power distant islands, farms, communities, refugee camps, and facilities such as remote and mobile hospitals. Also, in the future, it could transmit energy from Earth to space and vice-versa.
Wireless power could offer network resilience, ensuring energy after natural disasters and other emergencies, as the lack of wired lines reduces weather-related outages as well as electrocution risk. Atmospheric conditions such as fog, rain, or dust imperceptibly affect efficiency. In case there are transient objects such as birds or helicopters, a low-power laser safety curtain immediately and momentarily shuts the interrupted segment down.

Seeing through walls: Extended use cases for wireless power transmissionpowerelectronicsnews.com
A friend of mine, tasked with identifying projects for his power management team, was approached by a U.S. government agency within the Department of Defense. The agency was focused on drone technology: It was turning out to be quite costly to send these quadcopters out on a reconnaissance mission, only to bring them all the way back to their starting points for a battery refresh. What the Army wanted was a way to “refuel” these gadgets, in the air, and without a return to their base. Electronic powering for drones requires a charging system that can track and target them from a long distance. Long-range wireless power transmission may be achieved with a number different technologies (perhaps in concert). The technologies may include lasers or ultrasound as well as carefully-tuned electromagnetic fields.
