The ESA:s "Solaris" satellite made the historical energy transfer test from the orbital trajectory.

The energy transmitter of power satellites can use:

*Laser that operates in visible, IR, or UV frequencies. 

*Microwaves

*Radio waves 

To transmit energy to the ground.  

The ESA:s "Solaris" power satellite transmitted energy to Earth in the new experiment. The power satellites could be one solution for Earth's temperature rise. They can act as the solar shield that will cover the sun. And those power satellites can also transmit energy to the Earth in the form of laser rays or microwaves. That means power satellites can give multiple solutions in one package. 

Power satellites are not a new idea. The Boeing and Lockheed Martin corporations made the first research for those satellite-based power systems in the early 1970s. The reason for that was the energy crisis, but those plans were buried because of high prices. 

Another reason for that was materials that were not yet advanced enough. At that time. There was no nanotechnology. That means the structures were heavy. And they were hard to make. 

And also other technologies like AI that controls the entirety were not advanced enough. But now engineers and researchers can create larger solar panels that can fold themselves. So those solar panels can be like origami. Also, things like miniature shuttles and remote-controlled robots can help to create extremely large structures. 

Or otherwise, power satellites can also be a group of small-size satellites. In that kind of system, the power satellites are like a swarm. And they can aim their energy beams at one single point. By using extremely thin material is possible to make lightweight solar panels that can open themselves like blinds. And the body of the satellite can be very small. 

That means even large-size power satellites can launch into high orbit by using heavy launch vehicles. Those power satellites can give energy supply to the entire world. But power satellites can also use as killer satellites. If their energy beam hits another satellite or any other thing they can be extremely deadly. 

The power satellites can jam the GPS systems simply by covering the target areas using plasma. But those power satellites can also destroy even ground vehicles and structures if their power delivery is powerful enough. Those systems can also destroy ICBM missiles. 

The powerful radio, microwave masers, or laser systems can drop aircraft from the airborne. But those systems can also destroy ground targets. And they could be very useful tools against drone swarms.

The power satellite can also act as a high-power communication tool, and if its transmitter is flexible enough it can also be used as a radar platform. That system can have the most high-power radars. That has never been created before. 

And that thing makes those systems somehow complicated. But power satellites can deliver clean and safe energy for the entire planet. And they can make many things different than they were before. They are powerful tools in all areas where is a need for energy.
