Re: Winter cluster generating heat
The unhooking of the wings is not unhooking form each other although the above is correct they can be unhooked form each other. it is that the wings can also be disconnected from the muscle that moves them. This way the muscle can still be used as if the bees is flying without the wing moving.
When you work hard you get hot. This is because muscle is producing energy. Some of the energy is goign into the lifting.t he moving of your arms etc. but no energy transfer is perfect. and the most common way unused energy is passed off is by heat. energy of your muscles that is not used to lift or move. is converted to heat and your body is able to get rid of it.
Bees have muscle that are intended to power their wings. but they are able to disconnect that work from the muscle and use them as if they are flying. much more energy goes into heat than woudl otherwise. also using flight muscles is very efficient. in comparison flight muscles are the larges muscles of any physical body. Think of the breast of a chicken. that is their flight muscles. They are simply huge in comparison to every other muscle in the chicken. they have to. they have to be strong enough to lift the chickens entire body from the ground. Larger muscles produce more heat. So the bees are using the largest muscle they have to make almsot pure excess energy that is transferred into heat. IT works so well that not every bee in the cluster has to produce heat at all times. but it is actually just a few bees doing the job.
Stand for what you believe, even if you stand alone.
