Stanford R. Ovshinsky has been called “the modern world’s most important energy visionary.” Ovshinsky passed away in October 2012 at the age of 89, during his lifetime he registered over 400 patents including electrical and bio-mechanical innovations. He is a true genius of the 20th and 21st century. Ovshinsky was 100% self-taught, all his knowledge came from public libraries and experimentation. His greatest invention was his advancement in battery technology where he proposed a new type of design from the conventional nickel battery into a use of alloy of different elements that made the battery more powerful and durable. His legacy has made possible the increased lifetime of rechargeable batteries of most of the devices we use in our daily lives, from mobile phones, laptops to hybrid and battery-powered electric cars.
Here is one of his latest videos where he explains the rechargeable battery design technology.
