I don't deny global warming, but what is being done about it is crazy.
Personally I think it's what's not being done about it that's crazy.
Back on topic: I agree that a rethink of personal transportation is required. I think it is more important to rethink the things that cause us to need or want cars. Living in a different town from one's workplace is rarely if ever required. The centralisation of services that widespread car ownership has permitted (think malls or retail parks) is amongst the myriad of reasons we feel we need cars. Research like this is useful and worth while, but as others have pointed out what's really needed is a more fundamental rethink. I'd like to see us reordering our societies and lives in such a way that we don't need cars.
ie. Why is belly button fluff predominantly blue? I believe that the anatomical feature known as a 'navel' or 'belly button' is in actual fact a previously unrecognised organ that serves a vital role in the human body.
As we all know, blood is red. Indeed the red colour of blood is integral to the role it plays in the body. I propose that the belly button is actually a chromatic lung which is capable of absorbing redness from the environment into the blood and similarly expelling excess blueness in order to maintain a healthy balance. This may be the reason that environments containing excess blueness cause people to feel cold: the blood looses redness, in turn diminishing it's oxygen carrying capacity leading to an overall reduction in the metabolism that actually serves to lower body temperature.
Interestingly, there are reports that the navel fluff of aristocrats has a reddish hue, leading to speculation that they are in fact a distinct species. This has yet to be demonstrated under laboratory conditions and remains a controversial area of research.
Don't panic.
