Oh, triple unfold is a little more reasonable. Still, the 10-20 W was fairly optimistic; you might get the 20 W with a good panel with the laptop closed and the lid flat in noon sun. With the unfold it'd be enough power to charge and run an Atom laptop (charge at midday, use in shade earlier/later), but it's still not strictly comparable to Joey Hess's setup. Different scale, different purpose.
