CNN reported on the new speed record for a wind powered car that is able to go much faster than the wind itself! The design of this specific wind powered car allows to go directly upwind (at about 2X wind speed) and directly downwind (at about 3X wind speed), which is quite amazing. And this record is already official, as NALSA (North American Land Sailing Association) has ratified the upwind record at 2.1X wind speed.
