In short
In 1891, Nikola Tesla patented a system for wireless transmission of electrical energy, a concept he had demonstrated experimentally at his laboratory in Colorado Springs and later promoted through his Wardenclyffe Tower project. Though the technology never achieved commercial viability in his lifetime, the patent established the theoretical foundation for wireless power transfer-a problem engineers have pursued, with varying degrees of success, for over a century.
How it unfolded.
The five-minute version
What actually happened.
Nikola Tesla was an inventor who obtained around 300 patents worldwide for his inventions. Some of Tesla's patents are not accounted for, and various sources have discovered some that have lain hidden in patent archives. There are a minimum of 278 patents issued to Tesla in 26 countries that have been accounted for. Many of Tesla's patents were in the United States, Britain, and Canada, but many other patents were approved in countries around the globe. Many inventions developed by Tesla were not put into patent protection.
