Who could imagine life without our "man-made weather"? On cold winter
nights and hot summer days, we are forever grateful to the visionaries
who took two basic elements--fire and ice--and turned them into true
modern marvels. Fire warmed the caves and primitive dwellings of mankind
for centuries, yet the technology of keeping cool lagged far behind as
we learn in this chronicle of heating and air conditioning that covers
advancements from the home and industry to outer space and beyond!
