There is so much rooftop solar in South Australia that at times it supplies the whole state's needs. It's time the U.S. cut red tape so distributed energy can proliferate.

We were thrilled to host Matthew Moy, our first intern, at #Enzinc Manf Tech Center. When he joined in 2020 the anodes were 1cm & made in the tube furnace on the table. Now, commercial-size 16cm is made in the production furnace behind us. He is working on his PhD at #MIT & we are very proud of him.
