Lonnie Johnson, from super soaker inventor to battery innovator

The video discusses Lonnie Johnson, the inventor of the Super Soaker, and his journey from working on classified projects like the Stealth Farmer program to creating popular toys such as the Super Soaker and Nerf gun. Initially, Johnson was working on a heat pump using water instead of freon, which led to the accidental invention of the Super Soaker. Despite its playful nature, the Super Soaker was a significant invention. Johnson holds over 100 patents and has worked with NASA and the US military. Currently, he is focused on developing advanced battery technology that could store three times the energy of lithium-ion batteries.
