We Can Use Cell-Phone Towers to Forecast Wind Power

The company says that it now has sensors capable of tracking the wind data near 95 percent of the wind farms in Texas, and that its data is very accurate because it has put its sensors on cell phone towers.

Robot Cars Are on the Horizon!

Yes, that might alternately sound scary and impossible and far off, but it might happen sooner than most think.
