Solaroller Tractor Pull Video
April 29, 2007
FlatTop vs. 2-Cell in a dramatic tractor pull. For more information, see my previous post on Solarollers.
See the drag race between FlatTop and 2-Cell at YouTube.
The advantage in both cases goes to 2-Cell, although FlatTop does a lot better when heading south due to the angle of the Sun and 2-Cell’s two solar cells.
