Testing SIAPv9.2 80816-80817

Today, 16/8/08 I cooked ginger chicken using SIAPv9.2, and cooked rice using SIAPv6.1.

A whole piece of chicken thigh with the drumstick was mixed with ginger, little red onion, cooking wine and a pinch of salt. The whole mix was put inside the black solar-cooking pot and placed. The pot was covered with a glass greenhouse enclosure. Meanwhile, a 1.5 cup of rice was washed and put inside another blacken pot. This pot is also covered with a glass greenhouse enclosure.

Starting at 10:15am, the the solar cookers were setup and put in place for cooking. By 1:25, which was 3 hours later, the food inside the cookers were inspected. It was found that the chicken was over cooked! It was a bit too soft. Whereas the rice, it rice was rightly cooked.

I called up Solarist, Mr CM Tan. He comeby our place and we feasted
on a Solar-meal. After the solar feast, the sun was still bright. I therefore decided to cook something for the high tea this afternoon. I washed 1.5 cup of barley and put
it into SIAPv9.2 with submerged it in water. SIAPv9.2 was again put in place to cook at about 2:00pm. By then, the sun already swung through the top. SIAPv9.2 was repositioned to face the sun. It was somewhere in the region of 20-30deg towards the west. The barley was left to cook through 4:00pm. In between SIAPv9.2 was readjusted once to track the west bound sun. When the pot was finally opened at 4:00pm, the barley inside was well cooked. It was quite dry as there was little water to start with. Hot water and sugar was added to the barley and it was enough to served to 6 persons.

Solarist CM Tan was again invited to sample the barley. He commented that the barley tasted better than when it was cooked over a gas stove. The texture is different and it felt good to biting. It was tendon, yet chewy. If the weather permits, I shall try to try to cook something more challenging tomorrow. Perhaps I will cook lamb or mutton in spice.

SIAPv9.2 is tested today 80810

Today, the improved SIAPv9.2 is tested. It has a tiltable rack that allow the tilting of the solar cooker to track the sun, yet maintain a stable position for the cooking pot inside. SIAPv9.2 is used to bake hotdog. 4 pieces of hotdog was thoroughly baked in a hour under the hot sun today at around noon.

Testing SIAPV9.1 80803

Today, SIAPV9.1 was tested and it was used to cook rice. SIAPv9.1 is a Octagonal 3-angle solar-shuttle cooker made of paper box and lined with aluminum foil.



The experiment today was started at 10:30 and last till 12:00noon. Two cup of rice was cooked using this cooker within 1.5hours.

Testing of SIAPv8.2 20 July 2008

SIAPV8.2 maintains the 45 and 75deg inclination angles. The edge height however have changed and they are now both measure 300mm. This cookers is made of paper boxes and consists of 8 panels. The panels are knitted together using nylon strings and the inner of the cooker is lined with kithen aluminum foil.

During an experiment on last Sunday, the weather was not conducive and it was gloomy with much cloud overcasts. Water in the pot inside the cooker turned warm but did not boil over a period of 1 hour under the sun.


Testing of SIAPv8.1 16 July 2008

This is a dual angle: 45 and 75 deg shuttle solar cooker, with the edge height of 200mm and 300mm respectively. One of the challenges with this cooker now is to build a pot-holher which would enable the pot to stay upright when the cooker is tilted to face the sun.


Testing SIAPv7.3 on 21 June 2008

Testing of SIAPv7.2 on Sunday 15 June 2008

SIAPv7.2, two improved versions of metal funnel cookers were tested on Sunday 15 June 2008 at MJC in front of WydeDelta Essential.

The experiment:
In this experiment, a measuring cup of rice with water was put in each of the funnel cookers for testing and to compare the results. Today the weather is sunny and like usual with a lot of cloud. Starting at 10:45 am, everything was in place and the cooking has starting. By 12:45pm, two hours latter, the payload was inspected to see the cooking results.

The Results:
The rice in both cookers was almost cooker, but it tested a bit "powdery". According the "cooker expert", Mr CM Tan, it was a sign of under-fire. Meaning, not hot enough! I have a different opinion or rather hope that it was due to lack of water! I have faith that metal funnel cooker could cooker rice, the same way it ancestor did. Note though that its ancestor was made of HDB board instead of metal. The experiment would be repeated latter.




One on the unit was fixed with hinges so that it could be folded to facilitate transportation and storage, it is seen with a piece of PVC tube placing on top of the metal funnel. Pictures of SIPAV7.2 and it "payload", the food in the cooking pot is in the picture below respectively





The other unit is a older version SIAPV7.1, it acts as the control unit to compare and contrast results.
