Gasoline engines and diesel engines used by cars and trucks, and jet engines used by planes, need a supply of oxygen from the air to make them work. Things are different for submarines, which operate underwater where there is no air. Most submarines except nuclear ones have diesel-electric ...
It would not be wrong to say that many of us have had this question buzzing in my head since childhood. But as they say, necessity is the mother of invention. So, submarines have their means of producing oxygen continuously to help their crew stay underwater for days at a stretch. The ...

Cruise missiles come in a number of variations (see the links at the end of the article for more information) and can be launched from submarines, destroyers or aircraft. Left: AGM Tomahawk air-launched cruise-missile loaded on a B-52 Stratofortress Right: Ground Launch Cruise Missile (GLCM)...
Essentially, these are the only controls — heat to make the balloon rise and venting to make it sink. This raises an interesting question: If pilots can only move hot air balloons up and down, how do they get the balloon from place to place? As it turns out, pilots can maneuver horiz...

Why Do Diesel Submarines Have To Resurface? Diesel engines generate power through the process of internal combustion (the word ‘internal’ simply indicates that the diesel is burntinsidethe main part of the engine). Note that internal combustion engines are different from external combustion engines...
The most amazing section of the video is arguably the part where the gyroscopic bicycle wheel is able to hang in the air like this: The ability of a gyroscope to "defy gravity" is baffling! How can it do that? This mysterious effect is precession. In general, precession works like this...
