New TVA Dam To Power War Production

The video discusses the TVA's new $70 million project in North Carolina, focusing on the Fontana Dam, which is ready for its first test. The dam's giant turbines are expected to generate 200,000 kilowatts of power. During testing, 20 million cubic feet of water rush through the dam every second at 70 miles per hour. New spillways create massive geysers over Fontana, contributing to power production for war efforts.
