this happen,oakley necessity? In fact, the so-called thermal value is the heat emitted by the oxidation of the fuel in the atmosphere, and to know 8 kg oxygen for the oxidation of one kg of hydrogen per kilogram device + fuel together does not produce 1 kilowatt-hour of electricity. Anyone can imagine 12 kilowatt-hours / kg storage capacity, the Jinlong battery on the extent of China's satellite and spacecraft significance.
The Jinlong batteries are also used in plasma Micro momentum propeller. Many people obsessed with a spectacular back and forth in the The U.S. space shuttle, for example, that there is no air in outer space to the amazing speed of 8000 m / s along the orbit flight, it is the quality of more than 40 tons. Speed ??changes, angle changes have to rely on the pusher, even deceleration is true,official jerseys. Even hydroxide as the propellant (which is the highest energy), the ejection velocity of the gas, but also of 4000 m / sec, according to the momentum conservation law, if using one ton of propellant, it can only make the shuttle speed increase (decrease ) 100 m / s, the speed just change the eightieths of!
Plasma thruster is a completely different concept, which enables easily ionizable metal material is converted into a plasma, and then
?Plasma in a magnetic field to accelerate to 100 km / sec ejected. Such engine has practical use, but the thrust is very small, 1 kg weight class are considered the With hundreds of dozens of tons, compared to the hundreds of tons of thrust rocket engine can only be regarded as Do not u
