Prof. Peter A Ziegler

Professor Peter Ziegler passed away a few days ago aged 84.

RIP

Prof. Peter Ziegler (1928 – 2013) was a Swiss geologist  and Titular Professor of Global Geology at the Geological-Paleontological Institute, University of Basel. He is a member of the Royal Netherlands Academy of Sciences, the Polish Academy of Arts and Sciences, the Russian Academy of Natural Sciences and the Academia Europaea.

I posted in March about his presentation on the “Mechanisms of Climate Change” from February this year.

Eureka!! Turning Off the Air Conditioning Helps Save Fuel

June 29, 2010

The wonders of what now passes as SCIENCE (no doubt peer-reviewed).

Science Daily reports on major insights resulting from a study by “Empa – a Research Institute of the ETH Domain” on behalf of the Swiss Federal Office for the Environment (FOEN).

This ground-breaking study shows that Automobile air conditioning systems do not run “free of charge.” The article reminds us that Car air conditioning systems require energy to compress the cooling agent, and the greater the degree of cooling required the more energy (i.e. fuel) they use.

This is good strong stuff. I need more coffee.

The article continues. The study, the results of which have just been published in the scientific journal “Environmental Science and Technology,” shows that the fuel consumption of the test vehicles with air conditioning systems in operation increases with rising ambient air temperature and humidity, reaching a value of some 18 per cent on a typical Swiss summer day with an air temperature of 27 degrees and relative humidity of 60 per cent.

Wow!

This highly significant peer-reviewed, CO2 related (what else) paper is referenced as:

Martin F. Weilenmann, Robert Alvarez, Mario Keller. Fuel Consumption and CO2/Pollutant Emissions of Mobile Air Conditioning at Fleet Level – New Data and Model ComparisonEnvironmental Science & Technology, 2010: 100608141025002 DOI:

What is not reported is how much this nonsense cost. But since it has CO2 in the title it must be worth every penny.
