"From Horse Power to Horsepower"
by Eric Morris

This article is from the Number 30, Spring 2007 issue of ACCESS, the official magazine of the University of California Transportation Center.  ACCESS is published twice yearly.  www.uctc.net/access/access.asp#special
(All articles published in all previous issues of ACCESS are available for free download.)

Summary of interesting points from the article:

#1 - For thousands of years horses were used for personal transportation, freight haulage and even mechanical power. 
#2 - In the late 1890's a public health and sanitation crisis of almost unimaginable dimensions loomed due to the era's predominate mode of transportation: HORSES - nowadays considered a charming and even romantic animal.
#3 - Urine, flies, congestion, noise, carcasses and traffic accidents were huge problems.
#4 - Feeding each horse consumed 5 acres of land per year.
#5 - In 1880, in New York and Brooklyn, the horse population of 150,000 to 175,000 deposited between 3 and 4 million pounds of manure each day!
#6 - These horses also produced 40,000 gallons of urine each day.
#7 - In 1900. it was estimated that 3 billion flies hatched in horse manure each day.
#8 - In 1880, an average of 41 dead horses (1,300 pound each) had to be carted from the streets each day (15,000 annual).
#9 - in New York in 1900, 200 persons were killed by horses and horse drawn carriages.  The fatality rate per capita for automobiles in New York in 1997 was 7 times smaller!

This is a fascinating read!!  I loved how, at the time, the now hated internal combustion engine powered vehicle, the private automobile, was widely hailed as an environmental savior! My. my, how time changes perceptions! 

Technical evolution continues.  Solar SkyTran will become the next important anti-pollution solution.
