About Cryogenic Engine:
'Cryogenic is the study of substances at very low temperature in which gases like nitrogen, hydrogen and oxygen become liquid at minus 150 degree or less.
'This is the reason we called this as cryogenics engine, which use liquid hydrogen and oxygen as fuel that are stored at minus 253 degrees and then ignited to burn at plus hundreds of degrees centigrade .
'Cryogenic Engine was first used by US in 1963. India took almost 20 years to develop Cryogenic Engine.
