Paul Maas has nicely added in a Dexter Industries dSolar panel onto an 8041 Race Truck. I couldn't find any details other than the photos in his album, but it sure looks great. The dSolar panel allows him to run the NXT and motors without the need for batteries at all.
Why? As Paul quite eloquently puts it - "Because we can!"
