    Just entered the mac world, and I am likeing it. but I have one question, I have a brand new macbook Pro 13 and I have loaded bootcamp, why does it run hotter when in windows, I could understand if it had a dedicated card and just used that ,but it does not.

    I don't game with it but need it for some things.

    I think the reason is that the components are stressed/used more in windows. Perhaps the os x does a good job in saving energy for parts in idle then in windows. I am pretty sure this is why the battery life is also worse in bootcamp.

    It all has to do with how the components are used and the drivers that Apple makes. A unit can produce access heat even if it doesn't have a dedicated GPU especially if the IGP and CPU aren't being properly used. In my experience, CPU idle usage was about the same under Windows 7 and OS X. Things didn't start to meltdown until I started playing back HD video content (which leads me to believe it might have something to do with shoddy IGP drivers), Flash videos (though that causes OS X to heat up as well), and just generally surfing the internet. OS X might have better control over the cooling system of a MBP whereas the drivers provided by Apple under Windows are likely crappy.

    Either way, heat production and battery life reduction under Windows are rather normal even on units that don't have a dedicated GPU.

    This is why I try to keep up with heat to electricity technologies. It would be great if like a paper thin grid of material could be put in all excess space that when heated generated electricity... at least use the heat for something, while getting rid of some of it.

    this idea isn't new.. trying to use excess heat or light from the screen to help generate some more electricity... not something I came up with. It wouldn't be enough to power the machine, but it would be enough to extend battery life.
