DAR ES SALAAM, TANZANIA -- President Obama, an avid hoops player, hit the pitch Tuesday -- the soccer pitch, that is.

It was actually during a tour at a power plant here that Obama and Tanzanian President Jakaya Kikwete got a look at the "soccket ball" -- a soccer ball that has an electric generator placed inside of it. Invented by two Harvard University graduates, the balls can generate electrical power for lights and cell phones after they are played with for a while.
