Hi All,
I was wondering what is the highest power that has been transferred wirelessly in the state-of-the-art research? and what was the furthest distance for it?
This question needs more elaboration and explanation. As if one increases the distance the power the amount of power transferred wirelessly will decrease significantly hence efficiency will go down. So it's never about the maximum power transfer but with associated factors such as distance and efficiency.
According to IEEE Wireless power transfer, the maximum distance to transmit wireless power was around 150 km between two Hawaiian islands back in 2008 but the power was very low i.e. 20 W. Most of the power was lost in transmission.
Nowadays researchers are focusing to take advantage of the permeability of frequency-reconfigurable electromagnetic metamaterial to enhance the magnetic field and power transfer efficiency. It will enable us to transmit wireless power with better efficiency.
The highest power transferred wirelessly depends on the specific technology and implementation. Currently, the most common wireless power transfer technology is magnetic induction, which can transfer power in the range of a few watts to tens of watts over short distances. However, there are experimental technologies that can transfer power in the range of kilowatts over longer distances, such as microwave-based wireless power transmission. The amount of power that can be transferred wirelessly also depends on factors such as the efficiency of the technology, the distance between the transmitter and receiver, and the specific requirements of the application.
I have always wondered about the longest distance through which power can be transmitted wirelessly, and what is the maximum capacity that can be transmitted wirelessly, but I think it has something to do with the speed of wave propagation and its wavelength. I hope you share your answers with me
