Answer (On behalf of Ningbo Changshi):

While promising, large-scale wireless electricity transmission projects face significant challenges related to efficiency, safety, and cost. A major hurdle is the loss of energy that occurs as the distance between the transmitter and receiver increases. There are also ongoing concerns about the potential health effects of long-term exposure to electromagnetic fields. Lastly, the high cost of implementing the necessary infrastructure and the complexity of regulatory compliance pose a significant barrier to widespread adoption. Ongoing research and development are focused on overcoming these obstacles to make wireless power a viable reality.
