cost of heating/cooling - piston CC tuba design

... and I thought that this would be just another HB2-like thread...

China burns a lot of coal. I know of musicians who will not go there to tour or teach because the air quality is so bad.

Have you seen all the news coverage about athletes who are going to stay out of Beijing as much as possible, being there only for their events? And at least one who is not going to run the marathon because of the pollution.

While coal emissions can be cleaned up, I don't see China doing that any time soon. I wonder if they anticipated the horrible press they are getting because of the pollution. They just HATE to look bad, and I suspect that all the media coverage is at least somewhat politcally motivated.

And what I'm going to say next (and not as part of my reply to Marty) will probably cause the thread to be locked, but some of us of a particular mindset are a lot more interested in preserving what's left of the planet than in having cheap energy. The problem is that we breed like bunnies and use our religions as excuses to do so.

MA,
Thanks for saying that.
Peace. (now that's simple)

Surely anyone who believes they are contributing to global overcrowding and pollution can come up with a quick exit strategy...(or at least completely stop consuming resources, goods, and services)

bloke "ahhhh...more for *me* "

I strongly suspect that if the vast majority of "environmentalists" (along with their power structure-aligned ilk) were forced to use as few resources, goods, and services as do my family and I, they would squeal like l'il piggies.

Are you trying to say that one should not ride in a private jet telling others to be green? (I'm speaking hypothetically, of course)

. . . . Many of our recently-designed larger CC tubas are piston models with extremely short tuning slides. The practical tuning range on many of these instruments is only about 2 inches. This is the "trumpet equivalent" of 1/2 of an inch! Even if these slides are 2-1/2 to 3 inches long, (assuming proper alignment) we risk losing our slides on the floor if trying to tune to A=440 above 80 F. . . .

Nice to know that a short tuning slide is not my imagination on my Swiss-made, 5/4 rotary CC.

My solution is to use one or two sousa tuning bits, depending on the outside temperature.
