I appland the effort being undertaken with the solar plane and like the battery night time flying solution. The innovation is critical to get others thinking outside of the box. I still question the cost to produce solar power vs the traditional power generation cost. If and when solar can be competitive with water/coal/etc power generation costs then we will see a revolution. Until then, it is a neat concept but only a proof of concept and not a real world solution. Again, I love the idea but question the cost.
