What you're looking at is a tiny computer (the little box the mouse is plugged into), that uses ~8 watts, running off a beach-towel-sized solar panel.No more large-base linux robots! You could probably run this thing on D-cell batteries, and without the GUI, I bet they'll last quite a while too.
Oh yea, and they're only about \$250 (or \$120, I'm not sure if the two are exactly the same)
