June 2014, US Solar Cooking Survey: Quantifying Energy Savings of Thermal Solar Cookers in U.S. Households has been accepted for publication as a part of the American Solar Energy Society's Solar 2014 conference in July. This paper will present the first results of a 2012-2013 survey. More info at USA_Solar_Survey. Also expect more results presented at the SCInet Solar Cooking Convention 2014.
Natalia Blackburn has more than 20 years of experience as a registered mechanical engineer in California and Nevada, USA. During that time she has designed everything (it seems) from residences to universities, project managing the heating, ventilating, and air-conditioning; plumbing; fire protection; and electrical system designs.
Natalia and her family live in an earth sheltered home which they built in the mid 1980s. They have a PG&E bill of $30 per month. She has been actively interested in energy efficiency and sustainability for many years and has been a volunteer for Solar Cookers International for about 10 years. She solar cooks in the summer on her CooKit and HotPot, and finds that it is less hassle than an indoor stove and that it "makes the best rice we have ever eaten."
