New Zealand to transmit electricity through the air

The video discusses the development of a wireless electricity transmission grid, which aims to eliminate the need for metal cables and their supporting towers. This technology uses microwaves and engineered meta materials to transmit electricity efficiently. The system includes safety measures, such as lasers to detect objects in the path of the microwave beam, ensuring the beam shuts off when necessary. Wireless transmission offers advantages like reduced construction and maintenance costs compared to traditional methods.

What is the main advantage of wireless transmission over traditional metal cables?

How do small radios contribute to the creation of microwaves in the proposed system?

What role do engineered meta materials play in the wireless transmission system?

Describe the function of the rectenna in the wireless electricity transmission process.

What safety measure is implemented to prevent the microwave beam from affecting objects like birds?
