Background History
Ever since cell phones were introduced, cords twisting and knotting up have become a persistent problem. Wireless charging capabilities have always been dreamed of, and have finally arrived. While most people think this is a relatively new discovery, it was first discovered by Nikola Tesla in 1901. He created the "Wardenclyffe Tower", also known as the "Tesla Tower", to demonstrate wireless power transfer. Although the experiment failed, his developmental work can still be seen in prototypes today.
How It Works
Electromagnetic waves are created using electrical coils. They ways are then sent through a mat to reach the device being charged. Although initial designs did emit radioactive particles, newer models admit healthy amounts of radioactivity.Impacts/Future Outlook
As the technology further develops, the health risks and costs can be significantly lowered to be able to enter the consumer market. This means cords of the past could ultimately be worthless someday. Inductive charging could also greatly benefit the automotive industry, with wireless charges placed along or under roads for during use of electric cars.
Pros
- Less clutter
- More durable
- Can charge cars while driving
Cons
- More expensive
- Possibly dangerous
- Slower charging
