6th April 1660
The testing of the Devaraya atmospheric steam engine went on for two whole days, and fortunately, there were no problems found in the working of the machine. This was especially miraculous since a steam engine is a thing that had never been seen in the world before. Getting it right on the first try should have been impossible. However, if you think about it, it is not too surprising because Vijay has a higher technical vision. He can consider everything that could go wrong with the machine even before its construction, while others can only find out the problem one failure at a time.
Vijay called for Bhaskaracharya and arranged the next matters. His work in the research facility was done; his need was no longer required. With the design drawings and experience, the researchers can now independently build a steam engine if necessary.
