　　Time for the Shoutout.

　　Which American inventor was known as the "Wizardof Menlo Park?"

　　If you think you know it,shout it out.

　　Was it,A,Alexander Graham Bell,B,Thomas Edison,CHenry Ford,or D,Madam C.J. Walker?

　　You`ve got three seconds.Go.

　　Thomas Alva Edison was called the "Wizard of Menlo Park" for the work he did in Menlo Park,NewJersey.

　　That`s your answer and that`s your Shoutout.

　　Edison made some of his most famous inventions In Menlo Park.

　　A device that made it easier to hear on the telephone,the phonograph,devices for electric lightand generating electricity.

　　Of course,those inventions have been refined and improved on since the 1870s,and thoughsome people are concerned about a possible loss of their privacy when it comes to things likesmart grids,a model in Germany could be a sign of things to come.

　　In 1882,on Pearl Street in New York City,Thomas Edison opened the world`s first commercialelectric grid,lighting up local homes and businesses with cables connected to his power station.

　　Today,while the cars,the fashion and the skyline may all have changed.

　　The way we power our cities substantially hasn`t.

　　What if we could bring the whole grid up to date?

　　Let`s visit Mannheim in Germany.

　　Every house in Mannheim is connected to a smart energy network,making the most ofrenewable energy.

　　Now this is not just a set of smart homes,it`s a smart city.

　　What I think is that the power grid can become a brain for the city by all that information thatare generated in the grid.

　　We first thought about,OK,how should the future smart grid look like?

　　So we started with a very small number of households in the first project phase.

　　It was 20 households.

　　Then we grow that to 200 households in the next year.

　　And then the year after,we went to the large scale project with 1,000 private customersconnected to our grid.
