Miniaturized fast submarines, and their sophisticated usage from the fun to the scientific and military world.
Picture I http://kimmontaidearvioita.blogspot.com/p/miniaturized-fast-submarines-and-their.html Kimmo Huosionmaa New ultra-fast midget submarines can have many usages in the field of underwater systems. Below the text is three links, where introduced the new kind of midget submarines, what is extremely fast, and what can jump to the air, and what ownership would not need special permissions. Those midget submarines can also operate long-term under the surface if the air inside the vehicle would be clean. And if the air would be recycled thru the active carbon filters, that would give very long operational capacity. The power system can be based in the conventional combustion motors, what could also recycle the exhausted gas thru the filter, what separates the carbon from the carbon monoxide. But the fuel cells can also be used in this kind of spacecraft, what can be very sophisticated. There would also be systems, what allows to use the bicycling technique for rotating...
