The project startet out with an idea to make a solar cooker more effective, more flexible, more durable, lighter and cheaper. We tested reflective texture last summer and found a reflextivity of 63%. This is fairly good, even though less than…

How to reduce CO2 emissions equal to 200 millions cars?

We often hear about how the energy-sector and the transportation-sector contribute to CO2 emissions. But deforestation is in fact the second largest source of CO2-emissions. Of a total of 33,4 Gtonnes, 18% of is due to deforestation in the world. This is actual more than than the total emissions from all the world's planes, ships, trucks, and cars!  (PNAS, UNEP, REDD+)



In Norway we are for the moment discussing CO2 reduction in the range of 8 million tonnes. This is 0,05% of what we need to reduce in order to save the planet. Compared to our population, it is 1,6 tonnes of CO2 per individual and about 50% of what each individual on the planet needs to cut down on CO2. Compared to our total emission, which is 10 tonnes per individual per year, this is 16% of our total CO2 emission. But for many people in developing countries, 1,6 tonnes of CO2 is more than 100% of their total CO2 emissions!  It seems therefore that the richest countries in the world must take on themselves much more responsibility than the poor ones if we are going to succeed.  Politicians are pulling in different directions, and we are only discussing fractions of what we need to do. Where is the global systematic approach of how and where the cut should be made,-  in which sector, in which areas and so on? As I mentioned, deforestation is one of the areas where there is a great potential to cut down on CO2 emissions.  With relatively small investments, I’d like to point out how we can…

The making of the Kolamba Solar Cooker

The first prototype of the Kolamba Solar Cooker saw daylight already in 2009. It was based on the previous Deep Double Funnel Cooker that I made locally a few years ago in Congo-Brazzaville.

The Kolamba Solar Cooker is a more industrial solar cooker we've made together with Inventas in Kristiansand and with financial support from Innovation Norway and the EVA Center in Kristiansand.  



We started out in our home with small and simple models, and when measuring the temperature, we found that the temperature could reach about 130 C.

My oldest girl was very eager to test it out, and try out some recipes. 

We were curious if we needed the plastic-bag, but we found it to be quite troublesome. No bag could stand the intense heat without becoming crispy, and actually we did not need it to bring water to a boil.

In the first stage the reflector was 1 mm thick and it gave us a big problem for transportation. In the next stage we reduced the reflector to 0,2 mm thickness and also made a portable 6-folded bottom plate. We now had a mobile prototype prepared…
