+ Shine It All Around

It has been estimated that over 50% of the trees cut globally are used for cook fires. Gathering wood and burning fires requires tremendous effort and has a significant impact on the environment, communities and families. A great example of user-need focused concept that helps improve the quality of life for families is the solar oven. While a solar oven is not the magic silver bullet, it can be used to significantly reduce the amount of these problems and costs. The other part of the effort is getting the ovens to those families and communities.

The mission of the Solar Oven Society is to provide low-cost, effective, durable, attractive solar ovens, education and training to help families in sun-rich, fuel poor countries improve their environmental, health, nutrition, time and financial resources.

To learn more we spoke with Michael Port, Executive Director, Solar Oven Society

How much does the purchase of SOS sport solar oven in the US help someone else in another country?

When an oven is purchased here at the retail price helps us offer the oven at a very reduced rate to people overseas who really need an oven on a daily basis.
The oven is intended to part of the kitchen, it is not intended to replace traditional cooking completely, but it is a huge help to those families.
The ovens are not free, and we encourage people to never give the ovens away. Often times the people using the ovens are in cities, and traditionally are using up to 1/3 of their income for fuel, 1/3 for food, and 1/3 for housing. So even at a cost of $25 to $30 US dollars, if they save $5 a month in fuel costs, they can recoup the cost the of oven relatively quickly.


Many households in the US have some sort of oven range in their kitchens, as well as a microwave oven and an outdoor grill. How does a solar oven fit in beyond being another novelty appliance or piece of camping gear?

One of our upcoming efforts is to begin working selectively with power companies to include information flyers in utility bills on how the solar oven can reduce energy consumption, the other benefits it can proved and directing them to our website. We feel strongly that this can help people begin to consider and use alternatives. Most people cannot to afford to go out and purchase a photo voltaic cell based solar energy system for their homes, but they can easily begin to use the ovens and realize the sunshine can cook some of their meals and explore what else can it do for them. Another benefit is that the oven's main casing is made from recycled post-consumer PET plastic. Another way this will be successful is through word of mouth. When people know the ovens work they are more likely to be supportive of our overseas efforts.

Another thing that benefits the user regardless of locale is that slow cooking is more nutritious. The oven is safe, pollution free and cannot burn food!

An interesting feature of the solar oven is the use of the oven to pasteurize water. I was wondering what the combination of slow sand filtering could provide for people needing potable water?

If water is 150 degrees Fahrenheit for 10 minutes or more the waterborne bacteria and parasites are killed. The SOS Sport solar oven comes with a simple to use WAPI (water pasteurization indicator) that provides a sure test for water pasteurization. If there is sediment, etc the water may still need to be filtered, so a combination of slow sand filtering and heat pasteurization would be good way to get potable water without boiling.
We are also working with some retired 3M engineers to develop a system to pasteurize even more water quicker.

It has been estimated if we can somehow capture the energy that the earth receives from the Sun in 10 minutes time, that would be enough to supply the entire population for a year. We have a ways to go, but one thing our country is good at is coming up with solutions when we have to.
