Factually the power generation situation on border and the needs of navigation are flexibly set.
In a specific embodiment, the lift unit also includes：Hydrogen balloon and/or helium balloon.
Specifically, hydrogen balloon (the entitled Hydrogen Balloon of English) is that lightweight is bag-shaped or cryptomere object is full of hydrogen,
The object that can be floated up by the buoyancy of hydrogen is just hydrogen balloon.Hydrogen balloon typically has rubber hydrogen ball, plastic foil hydrogen balloon
It is several with cloth coating hydrogen balloon.Specific hydrogen balloon cost is relatively low.
But it note that hydrogen and other objects friction generation electrostatic using hydrogen balloon and run into naked light, high temperature, electricity fire
Flower, can make the combustion of hydrogen of inflammable and explosive property explode, therefore can be used as needed.
Further, it is also possible to using the helium balloon filled with helium, wherein, helium (Helium), for one kind of rare gas.Element
Name derives from Greek, and original meaning is " sun ".Helium is colourless, tasteless gas under normal conditions, and helium is can not uniquely to mark
The material solidified under quasi- atmospheric pressure.Helium is most inactive element, does not form what compound substantially.The application of helium is mainly
As protective gas, therefore compared to hydrogen balloon, will not combustion explosion, security and reliability are high, but cost is higher, because
This can as needed and specific usage scenario choose extra lift unit of the suitable balloon as lift unit.
In addition, the lift that hydrogen balloon or helium balloon are provided can be determined by equation below：
Gravity and aerostatic buoyancy of the balloon by itself.
Hydrogen gravity in self gravitation=balloon gravity+ball；
Aerostatic buoyancy=air averag density * g* balloon volumes；
According to Newton's second law：As long as aerostatic buoyancy-self gravitation=ma>0, you can lift is provided.
In a specific embodiment, the device of solar generating includes solar film battery.
