Ambri is commercializing battery technology invented at the Massachusetts Institute of Technology.
Dr. Donald Sadoway invented the liquid metal battery after decades working with extreme electrochemical processes.
Ambri says its batteries reduce the need for power plants and lines, make renewable energy sources more manageable and reduce costs.
According to the UN, 20% of people do not have access to modern electricity and rely on burning wood, coal or animal waste.
In 2012, Donald was one of Time Magazine's 100 Most Influential People in the World.
