Solar dyes give a guiding light

wow, that is pretty cool. As right now, the big issue with solar panels is how inefficiently they absorbed the suns light, via, only absorbing certain spectrum. Granted, it seems like you would have to re-coat the panel somewhat often, but i guess if the cost is low enough, no real problems.
 
That is sooo sweet! My dad has said before how it's rather wasteful to have all those modern glass buildings because the glass is less insulating than, say, a brick building. That being the case, those glassy sky scrapers and other company buildings have to be air-conditioned more (thus using up more energy) than would otherwise be necessary. Well, maybe this way everyone can be happy? The businesses and everyone else can still enjoy the glassy, fancy-shmancy buildings and make them energy-efficient at the same time? That would be fantastic!
