History of the Sun Oven
Sun Ovens were developed in 1986 by Tom Burns, a retired restaurateur from Milwaukee, Wisconsin, who was very active with Rotary International. From his experience in operating restaurants he knew a great deal about cooking and from his international travel he became aware of the ever-growing problem of deforestation. Tom took a concept that has been around for centuries and engineered into it more recently developed materials to produce the world’s most effective solar cooking devices. With the help of the Sandia National Laboratories the oven was refined.
From 1986 to 1997 Sun Ovens were made and marketed by Burns Milwaukee, Inc. Thousands of portable models have been shipped to more than 126 countries around the globe. Sun Ovens have helped feed refugees in relocation camps, natives in remote Third World villages, workers at field sites, climbers on the slopes of Mount Everest, and soldiers during the Persian Gulf War.
In 1998 Sun Ovens International, Inc. was formed and the manufacturing was moved from Milwaukee to Elburn, IL (40 miles west of Chicago). Sun Ovens International, Inc. has expanded the use of the ovens by making them more widely available in the U.S. and around the world. Assemble plants to make Sun Ovens have been established in a number of developing countries to reduce the cost of the ovens and shipping to the people that need them the most. While thousands of ovens have been sent around the world, there are still more than 2 billion people who cook with wood and charcoal and as populations increase so will the need for Sun Ovens.
News and recent developments
- April 2013: Interesting facts about the Sun Oven - Recently Paul Munsen, the company president, was questioned about where their ovens were being sold. They have been sold in over 130 countries. The Sun Oven is usually considered to be the standard which other solar box cookers are judged by. They are well made of quality components and quite durable. They have a revised version of the Sun call the All American Sun Oven that has a 20% larger cooking area and new wind resistance features. Interestingly, forty-two percent of the Sun Ovens sold worldwide are sold in the state of Utah, USA. Munsen believes seventy percent of the ovens are being kept on shelves with emergency food supplies, the rest are used on a regular basis. The owners appreciate the versatility of the cooker, with the added benefit of helping to lower household kitchen temperatures during hot summer months. When Munsen was recently demonstrating in the Sun Oven in Afghanistan to a group of local women, he was told the cooker could not provide the smoky favor desired in their flatbread, known as naan. Paul's wife suggested adding a few drops of liquid smoke to the batter. A recent delivery of ovens was accompanied by a 55-gallon drum of liquid smoke. The liquid smoke offers some advantages over smoky fires. Munsen says women cooking over fires can inhale as much smoke as they’d get from smoking three packs of cigarettes a day, and children are more likely to contract acute lower respiratory and eye infections.

- April 2008: Sun Ovens International is now assembling the Global Sun Oven in a factory in Haiti. A microfinance system is being used to make these ovens available to poor people who need them. An average family spends $2.30 (U.S.) per week to purchase charcoal. A Sun Oven can be used for 70% of their cooking and will save an average of $1.61 a week in charcoal expenditures. Weekly payments are set at $ .97 (60% of the savings); the remaining $ .64 per week creates an incentive to solar cook and takes money that literally was going up in smoke, distributing it through the local economy. Initially, the challenge of implementing this system was that women in Haiti live very much one day at a time and even though they saved a high percentage of their income by using a Sun Oven, they rarely had a long enough view to understand that they were saving money. To overcome this problem, cardboard solar panel cookers were introduced. Women received 3 days of training centered around the construction of a cardboard solar panel cooker, the principals and concepts of solar cooking, and the frailty of the Haitian environment. The training occurs over lunchtime, and the first two days, Haitian foods are cooked in Sun Ovens and served for lunch. On the third day, a solar potluck is held. Each student prepares food in their own cardboard cooker and shares it with fellow trainees. As part of the training, participants receive a log allowing them to document the use of their cardboard cooker and the amount of money they saved by not using charcoal. Participants who use their solar panel cooker on sunny days, for 90 days or longer, can use their log as a down payment on a Sun Oven. The Sun Ovens cook food much faster and can be used to cook the evening meals. After 90 days of documenting the use of the cardboard cooker, women have a much better understanding of the financial benefits of cooking with the sun and are eager to agree to a payment plan to obtain a Sun Oven.
