For our bio-diesel project we are using solar panels. But not in a traditional sense. We have a battery based system where the panels charge the batteries. We then take that DC current and invert it to AC current and use it to run circulation pumps and instrumentation (thermocouple and flow meter). We also have a switchover where we can run the power from the batteries (panels) or from the main (Jamaica Public Service Co. or JPS).
We are getting close to making bio-diesel and are just waiting to install the heat exchanger and a few minor items. The latest setback was in our quest for free Waste Vegetable Oil (WVO). We took an empty drum to one of the pattie restaurants in May Pen. We have formed a cooperation with them where they will give us some of their waste cooking oil (WVO). Over the weekend, however, somebody had climbed the fence emptied all the oil in the drum and stole it. Don't ask me what they will use the water for. Perhaps water, but they will find it quite difficult to get all the cooking oil out so they can drink out of it. (These drums are expensive at over J$1500 a piece.) Maybe the drum will turn rancid on them.
