Below a steam cooker build in Auroville.



Types of solar cookers
There are several ways to use solar power for cooking. Here I won't go into the different designs but only the principle differences (imho).

1. Direct mirror concentrator
For third world aid there have been projects in which even simple aluminium foil on carboard was enough to concentrate sunlight several times and bring water to a boil. This design could best be made out of a rugged material like… Continue

Meeting Dr. R.K. Pachauri Chairman, Intergovernmental Panel on Climate Change The Copenhagen Climate Conference can't be deemed a succes. The US is opposing significant cuts and current targets leave an estimated temperature increa

I found the metal to be costly, and I had a concept of a building kit with costly wooden parts, so I replaced the metal rods with strips of wood.

First I had to make sure the uneven parabolic shapes could be connected in a regular way. That required ma… Continue

(Mirror with coating still on)

It is not that hard to build a parabolic trough collector, even not for me not being all that handy with tools. I got started a few days ago and am trying to just make one and figure out optimizations as I go.

Step 1. Calculating the Parabolic Shape

You can use the formula Y=(X*X)/4*f where Y and X are re… Continue

Here is an example of how easy it can be to construct a parabolic mirror or SolarBowl. You can dig one out of the ground.

The 30 meter diameter construction was actually a so called 'Radar pit' for the dutch radio station Kootwijk. It was filled up in 1960, so it is no longer there. To… Continue
