Solar Tracker: I'll follow the Sun

Cue up I'll follow the sun from Beatles for Sale and admire the Solar Tracker, "an automated solar panel that actually follows the Sun for increased power. Capable of rotating over a 160° east to west, the Sun Tracker will increase the power output of photovoltaic arrays by over 200% by keeping the face of the panels parallel to the sun throughout the day." To us it looks like it tracks vertically rather than horizontally when it should do both, and it doesn't come with solar cells (which we think a bit deceptive) and wonder if they should not say perpendicular rather than parallel, but cool nonetheless and since childhood Edmund Scientific has entertained and educated us. ::Edmund Scientific via ::Red Ferret
