Mission Lightings for Pahang

We were blessed for being able to visit churches in Pahang jungle through a Christian friend. Through his local contact, we went in to provide lighting for the churches in the jungle using LED Lamps powered by Lead Acid Batteries.

On our way to the base camp, Tual, the road was rough and muddy. The locals would hitch a ride from us to return to their village.

When we reach the base camp, it was like a sanctuary, very peaceful, with basic amenities available, like fresh water from the hills, electricity, food (must say, the food was very good) and proper shelter.

Next morning, we went to a church at Regang, we gave a sermon, had fellowship meals with them.

In the afternoon, we return to Tual. We had another church service at Tual. We gave a sermon. Offered our prayers and had fellowship meals with the elders.

In the late afternoon, we set off to Senderut. They have a church located at Senderut. It is 510 meters above sea level. It had just rained, the road was muddy and slippery. Fortunately, the vehicle did not get stuck in the mud. We finally arrived after sunset. The church was dark, we quickly install 6 LED lamps in the church and powered them by a 12Vdc lead acid battery. We conducted the church service at night with the lights on, we had fellowship dinner with them and stayed a night in the church. The temperature in the morning was 17 degrees Celsius.

Immediately, the next morning, we set off to Kaki Bukit Long. Finally we reach there, park our vehicle outside the church and walk up hill to Tigol and Saweh. It was 468 metre above sea level.

We passed by Tigol church. It was 543 metres above sea level. There was no church service that day but the service was at Saweh.

We continued walking up hill and went to a church in Saweh, they had their morning church service, we gave a sermon and had breakfast fellowship with them. This place is 570 meters above sea level.









Finally, we return to the church at Kaki Bukit Long. We attended the service and had some sing along session. We installed 6 LED Lamps at the church, powered by a 12Vdc Lead Acid Battery.

Solar Two - Solar Food Dryer & Vacuum Sealing

We attempted to build a solar food dryer, using the sun energy to hygienically dry fruits in Cambodia. We have search through the internet and came across a design which we can try out.

We bought wood and cut the to shapes and assemble them together. Finally, we painted it and allow it to dry before using it.

Sun energy is collected through the transparent plastic and heats up a wire mesh inside. Air intake from the front sucked in and heated up by the wire mesh, the hot dry air rises because of convection in the dryer and flow into the drying chamber behind. The fruits prepared for drying are placed on trays to be dried in the chamber. On a hot day, the temperature in the chamber reaches about 50 degress Celcuis and humidity falls to below 30%. Drying takes about 3 days.

The temperature and humidity of the drying chamber was measured from night time till the next evening. It was noted that the humidity at night reaches above 80% while its temperature drop to below 30 degress Celcius. During the day, the temperature in the chamber increases to above 50 degrees Celcuis and the humidity falls close to 30%. Drying of the fruits takes place only during the day time.

The result was partially successful. Somehow we could not get complete drying of the fruits. Probably due to condensation of moisture at night.

Hence for the next improvement to the design, we must introduce continuous drying process through the night which we will require some heating process.

In conjunction with the solar dryer, we design a vacuum sealing machine to store the dried fruits in a vacuum sealed plastic bag. The machine does not use electricity but working on the priciple of a reverse bicycle pump for sucking the air out of the plastic bag and using fire from a candle stick to seal the plastic bag.

Solar Two - Fire Store Construction

On request from the orphanage, we build a fire stove for them. We got all the children in the orphange to help in carrying the bricks for the stove. We visted one of the villager's house to study how a fire stove is constructed. We came back using a double walled stove to prevent heat lost to the outside wall when fire is lit.

For the top, we constructed a mould and later put cement into it and allow them to dry before removing them. The hole size is determined by using their largest cooking pot.

We prepared the ground where the stove is to be placed and began brick laying.

We have a specialist who is good at mixing cement, sand and water in the quickest possible time.

Finally, we could see the shape of the fire stove. We place the pre-fabricated top onto the base of the fire stove and to complete the job, plaster the bricks to provide a good finishing touch.

Solar Two - Clean Water for an Orphanage

We installed a water filtration system for another orphanage in Cambodia. We used an ultra-membrane filter with pore size of 0.1 micron. It is able to remove bacteria and give clean water. It requires a minimum water presure of 2 bar to operate, hence we need to install an electric water pump before the filter so that it has enough pressure to operate the filter. A setback of this system is it requires regular back flushing in order to clean the filter to prolong the filter's life. Once the filter to clog up, it is time to replace a new filter. Suitable for making rainwater drinkable.
