Electric-jet engines or plasma-jet thrusters can connect with solar energy.

The plasma-ion thrusters and plasma-jet engines can have virtually unlimited operational time. The problem with electric jet engines is that they must have electricity from somewhere. 

There are two ways to make virtually unlimited operational time for aircraft. The first one is to use nuclear power. 

And that kind of system is otherwise easy to make. But nuclear power technology is an extremely dangerous thing. A damaged nuclear reactor can deliver highly radioactive containment to a very large area. If that craft will drop. It can cause nuclear pollution in large areas. 

There is the possibility to make solar-powered aircraft that use plasma jets or plasma ion thrusters. The idea is that the aircraft. Much like a U-2 spy plane would fly at high stratospheric attitudes. In those altitudes, long wings are necessary.

Those wings can be coverer by using solar panels. The thin air makes low friction. And it makes it possible that this system can fly at quite a fast speed. But solar-powered aircraft can also be hypersonic. Energy production can boost by using windmill turbo generators. 

But another way is to make hypersonic aircraft that use plasma thrusters or plasma jet engines. The system bases the ability to make origami-type lightweight solar panels that can be pulled inside when the craft is not using them. The hypersonic aircraft can jump away from the atmosphere, open its solar panels. When the batteries are loaded that craft can drop back into the atmosphere. 

While traveling in the atmosphere, the aircraft can use a windmill turbogenerator. For slowing the emptying of batteries. 

The fact is that the solar-windmill generator combination can use along with remote loading systems. The remote loading system can shoot the aircraft by using radio rays.  '

For loading the electric systems in the night time. The thing is that imagination is the limit in futuristic concepts. Energy production with green systems is a very interesting thing because there is always a risk of accidents.

Cheap WIG (Wing In Ground) aircraft and the capacity of that technology

The new era of aviation is so-called cheap aircraft, what can be equipped with same engines as cars, and what are easy to control. Above the text is a link to the video, of EKRANOPLAN of WIG (Wing In Ground) vehicle, what uses hybrid-motors. Those engines are actually electric motors, what is connected to a generator and car motor. That system gives this kind of aircraft capacity to use normal petroleum as fuel.


WIG-technology means that under the airplane is made the air cushion, and the airplane is laying on it. The system is actually quite easy to make, and it needs only the flaps what makes dam under the wing of the plane. This flap turns down, and it can give airplane the capacity to flight very low altitude with very high speed.

The air cushion makes this kind of low-level flight safe. Those WIG-flaps are tested in carrier-operative fast attack aircraft because that allows the plane attack against ships at very low altitude and high speed. But that technology can give more capacity for cargo-aircraft, what carries very heavy cargo because it can give the extra upthrust to airplanes.


WIG aircraft could be very large, and that’s why it fascinates many actors. Those aircraft can carry troops and tanks to beaches at very high speed. And this is the reason, why the Soviet Union tested high-speed low-flight amphibious aircraft in Caspian sea. This aircraft was delayed, but the smaller craft would be still in service. The similar technology what is used in WIG-aircraft can also give the airplane capacity to fly extra high altitude.


If the wing of the aircraft would equip with the flaps, what is turning downwards that would dam the air under the wing. This would help aircraft to fly in the stratosphere. If under the outer edge of the wing would be put the small plate, what is downwards, can it stop the stabilization of pressure and even that gives high-altitude aircraft like U-2 spy-plane capacity to fly extreme high altitude, but then all the wing would make overpressure under their area, the airplane would fly even higher.  And if the motor would get oxygen from the bottle, it would give thrust in the near the limit of space.
