Takeaways

• 😀 Nikola Tesla first proposed wireless electricity transmission over 100 years ago, demonstrating the potential with his Tesla coil and experiments in 1899.
• 😀 Tesla's early experiments showed that he could light a bulb over 3 km away, but they also caused power outages in Colorado Springs due to the massive energy involved.
• 😀 Wireless electricity transmission continued to develop with notable advancements like NASA's successful transmission of 34 kilowatts of electricity over 1.5 km in 1975.
• 😀 In 2015, Japanese researchers transmitted 1.8 kilowatts of power over 55 meters, marking progress in practical wireless energy technology.
• 😀 Currently, wireless power transmission is mostly used in devices like smartphones, but at very short distances and low power.
• 😀 Emmrod, a New Zealand startup, is working to commercialize wireless power transmission with a system that uses advanced technologies like metamaterials and radar optics.
• 😀 Emmrod’s wireless power system focuses energy into a beam, unlike Tesla's system, which radiates power omnidirectionally.
• 😀 The system works by transforming energy into electromagnetic radiation, which is captured by a receiving antenna and redistributed locally.
• 😀 Emmrod's technology promises to transmit power over long distances (up to 40 km), with a clear line of sight between the transmitter and receiver.
• 😀 Safety is a priority in Emmrod’s system, which includes laser safety measures to avoid harm to animals, and the power density is kept safe for commercial use.
• 😀 If successful, Emmrod’s technology could revolutionize power distribution, potentially reducing the cost of undersea cables and providing reliable energy to remote areas.

Q & A

Who first considered the concept of wireless electricity transmission and when?

Nikola Tesla first considered the concept of wireless electricity transmission over 100 years ago, experimenting with it in 1899 at Colorado Springs.

What device did Tesla use in his early wireless electricity experiments?

Tesla used the Tesla coil, a type of circuit that generates alternating current electricity, to demonstrate wireless power transmission.

What was the outcome of Tesla's experiments in Colorado Springs?

Tesla successfully lit a bulb from over 3 km away, but the experiments also burned out a dynamo, disrupting the local electricity network.

How has wireless electricity technology been applied in modern times?
