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…

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…

Just started MSO 2013 :-))

Hello to All SO enthusiasts :-))

Finally have started to build my new "MSO-2013" - (my solar oven).
I'm not sure how many mistakes I will make this time, since there is NO workshop, but here is a funny little cat, there is not too much space, but a part of a table in my studio, there is NOT everything prepared so far, but here is a great determination to build it and to see it cooking during winter-time. Let us see :-)) RGDS - Ed

Havn't been involved for a while but here are the latest details of my solar stuff.

Other things took over so solar was left behind. I did solar dried plums without breaking the plum skin this year and that was a success. (I just had so many at one time that it would have overwhelmed a solar drier.) I just dried them on black landscape fabric under a frost cover of white remay cloth.  I expected mould and problems but they stayed good as long as they were dry and gradually became prunes and really tasty.  In a dry fall, I found it was not the heat but the constant lack of…

Latent-Heat solar cooker

“There are a lot of solar cookers out there, but surprisingly not many using latent-heat storage as an attribute to cook the food.” (barbequelovers)  The remark comes from David Wilson, a MIT professor. He has found a way to conserve the energy of the sun by using a Fresnel lens to melt down a container of Lithium Nitrate. Lithium Nitrate is a salt with a melting point 491 F or 255 C, (Wikipedia) which makes it ideal to conserve energy for solar cooking. It even promises to allow for…

Solar PV System for Domestic Power Generation

Solar PV Electricity generation systems are designed to capture sun’s energy through the photovoltaic cells. The photovoltaic cells are the gateways that trap sunlight and transform it into electrical energy. This energy is then used to power various homes without wasting scarce natural resources as fuel.

The fuel in this case is the abundantly available sunlight. Hence, the solar PV systems installed in homes are sufficient to meet most of the electricity needs. Moreover, the…
