That is to say, the project is aimed at 100% local content. The Institute has carried out feasibility report on the project and established links with some companies in China for technical know-how, machinery, production accessories and training/man development in the area of pencil making.

Immediately it was conceived and approval given, design of pencil factory buildings, housing Graphite Beneficiation, pencil lead production, and pencil making commenced. In addition, arrangements were made for procurement of pencil making machinery from China and commencement of installation. About 21 pencil making machines performing specific functions were installed and awaiting test production.

Development of PRODA Electric Vehicle

First Stage R & D Scope of Present Work

The Electric Vehicle conversion done in PRODA used a small Toyota Starlet car. The converted vehicle can carry the full passenger load of four persons and cover up to (80) kilometers per hour. It has a range of about one hundred (100) kilometers for battery recharge. It is powered by a seventy-two (72) volts d.c. battery (6 nos, 12 volts batteries) capable of five thousand (5,000) revolution per minute. This is the first attempt in the Institute in converting petrol fired engines to Electrical power driven. It is hoped that further R & D will result to more efficient and economic version of the Electric Car.
