Reply to News Release: NREL Creates Highest Efficiency 1-Sun Solar Cell - 39.5% efficiency by TimeSpentWasting
I guess this is good for the tech as a whole but from what I remember in doing my masters thesis on solar cells, these records are produced using really tiny cells and the efficiency figures don't hold up at all as you scale them up.

Mopeds used to have pedals! That's what the "ped" bit in the name means. I actually think there's something in having a compact vehicle like this that can have pedal assist to boost its range/flexibility, guess Honda think something similar.
