AC vs. DC.  Tesla/Westinghouse Vs. Edison.  Case closed...or is it?

​

• Purdue’s DC nano grid house.  More Efficient.  Lower Cost.  Powered by solar panels, batteries, or local utility.

• Digital DC Networked Electricity.  “Villages worldwide without access to electricity are now afforded the opportunity for independence by building and managing their own infrastructure. Open the crate, plug the components together, and hours later, multiple homes will have sufficient power for lights, fans, a small refrigerator, TV, and communal water purification. And with our “pay-as-you-go” platform, electricity is affordable and accessible to all world citizens!”
