Concept cars usually just annoy me, but I find this one rather pleasing. 

I also like the idea of an adventure vehicle that needs to just sit in the sun for a while before moving.

Which reminds me of Bruce Sterling's Islands in the Net.

Now where's my solar powered, electric, offroad, rail buggy.
