Not enough trained workers
That's the point this article makes when it comes to folks who can tell what's inefficient within an old building. Looks like a great American opportunity to me. What do you think?

Like heating history?
I found this old Hoffman Catalog from 1929 and scanned it for you. It's here (open the PDF in the Info box). Some great descriptions of how the old stuff worked in this one. Enjoy!

Nothing to do with heating
But it does have to do with the problems you may run into while trying to be green. In Europe, where people were stockpiling incandescent bulbs just before the folks in charge outlawed them, there seems to be a problem with some tellies. Hey, I was watching that!

In your backyard?
So what if they made that incinerator cute, or at least interesting? Would you want it next door? If you lived in Europe you just might. Check this out.

And a bit of wackiness from the Land Down Under
Would you send your kids to a school that allowed this sort of heater? And I love the solution: Open the windows!

Body heat
The Mall of America in Minnesota has long used body heat to warm the huge place, but all of that heat is self-contained. In Stockholm, they're now using the body heat generated by the tens of thousands of people who pass through each day to warm a nearby office building. It's a very interesting low-temperature, heat-transfer experiment and you can check it out here. Be sure to watch the video.

Don't try this at home!
Thanks to my friend, Mark Eatherton, for giving me a head-up on this very cool video from Steve Spangler, which shows that there is indeed an atmosphere. I once saw this happen to a compression tank when the contractor drained the water from the apartment building without letting air into the tank. He had quite the look on his face.
