Maharshi Bhardwaj in his book Brihad Viman Shastra has given the recipes for making many instruments. In one chapter he describes an instrument called GuhagarbhaDarshanYantras, which helps to detect any arsenal hidden underground. This instrument has many parts, but this paper we report the results of our efforts to prepare three instruments: Panchloha( sutra No 38-41), Pargrandhik Drav (sutra No 42-46) and Chumbak Mani( sutra No 47-50). It is observed that the instruments work like a photoelectrochemical cell, where solar energy is converted into electrical energy. A flux material developed is very reactive and can dissolve sand, iron and platinum even at 600°C. Chumbak mani which behaves like a magnet shows metallic as well as semiconducting properties. It is concluded that the given in the book for the preparation of these materials are genuine. It is also suggested that there is a need to carry out experiments on all other recipes described in the book to find out their usefulness.

Abstract


Maharshi Bhardwaj in his book Brihad Viman Shastra has given the recipes for making many instruments. In one chapter he describes an instrument called GuhagarbhaDarshanYantras, which helps to detect any arsenal hidden underground. This instrument has many parts, but this paper we report the results of our efforts to prepare three instruments: Panchloha( sutra No 38-41), Pargrandhik Drav (sutra No 42-46) and Chumbak Mani( sutra No 47-50). It is observed that the instruments work like a photoelectrochemical cell, where solar energy is converted into electrical energy. A flux material developed is very reactive and can dissolve sand, iron and platinum even at 600°C. Chumbak mani which behaves like a magnet shows metallic as well as semiconducting properties. It is concluded that the given in the book for the preparation of these materials are genuine. It is also suggested that there is a need to carry out experiments on all other recipes described in the book to find out their usefulness.
