Answer to Question 1
Iomega was the first company to invent removable storage. Any investor who
thought about it then was imagining a huge growth potentialeven if that investor couldn't
label it exponential. In their minds' eyes, they were drawing straight lines on semilog paper.
They were rewarded, because Iomega growth was exponential for some time.
The situation is different now. Iomega's main growth spasm is over. It still sells some Zip
drives and it continues to sell Zip disks, but the market for Iomega Zip drives is saturated
now.

About 820 Mt of animal waste is generated in the United States every year. There have been
severe problems when retaining dams on lagoons have broken and wastes have escaped into
local streams. North Carolina has almost four thousand such lagoons. Researchers at North
Carolina State University, who are working on five technologies to reduce the environmental
impact of hog waste, said Waste from large hog and poultry farms has been blamed for
polluting surface waters, contaminating wells, creating noxious odors, and discharging
ammonia into the air. Treatment and disposal of the waste costs farmers tens of millions of
dollars each year. Interestingly from the viewpoint of Chapter 23, one of these ideas
involves using anaerobic digestion on a large scale.
