How to secure a data center's energy supply?



The lack of electricity will shut down almost the entire infrastructure. That means that energy is a good way to blackmail Western society. Damage to energy infrastructure can cause terrible situations. If we think that the entire stale is left without an electricity supply, that causes situations where communication and other things are in danger. 

In petroleum stations, the pumps will not work, and telephones won't work. In the case of the war, military personnel will not get messages to regular mobile telephones. 

But what if only the data center or computer infrastructure will shut down? In the military world, computers will control things like air defense systems whose mission is to shoot down enemy missiles. 

The data center requires a lot of electricity. Those data centers can play growing roles in national security and military systems. The robots that operate on the field outsource their complicated data handling processes or "thinking" to those systems. The robot communicates with the data center. There is the AI that connects all systems on fields under one dome. Data centers also play a big or even dominating role in a modern environment. 

Communication between the data center and field-operating systems happens using relay aircraft, stratospheric satellites, and satellites. The term stratospheric satellite means drones that have the same missions as communication or some other satellites. 

The growing role of the data centers causes situations. Where those systems are more and more attractive targets for enemy attacks. The high-power EMP weapon or nuclear- or conventional strike against data centers or their communication can destroy or damage the brains of the systems.  

One of the answers to the power supply problem can be the miniature nuclear reactors. The mini-nuke or portable nuclear reactors offer a good alternative for power supply. But there is always a small possibility that somebody tries to damage those miniature nuclear reactors. The miniature nuclear reactor uses molten salt for cooling. They can offer a solution that separates the data center from the power network. 



Orbital data centers, are they the answer to the data center's energy problems? 

Orbital data centers are solutions that address energy challenges faced by data centers. The orbital data centers can be one large satellite. Or they can use cloud-based architecture. The cloud-based system is a swarm of satellites whose computers are connected together. 

The cloud-based architecture means. Those satellite groups or swarms can communicate with each other using radio waves, coherent radio waves, or laser beams. Those laser beams can travel freely in space. Or those satellites can be connected. To each other using optic fibers. Those satellite swarm bases are in the existing technology. 

Those satellites can travel to the orbiter in regular rockets. But the problem is that they must have some kind of protection against solar storms. The satellite swarm must also be far enough from Earth that it can avoid orbital collisions. Things like electromagnetic shields that can push ions away from the satellites are necessary.

And then another thing is that. Those data centers or data satellite swarms's functionality must be confirmed in the case. That somebody tries to damage them. There is always the possibility that somebody puts the nuclear weapons on orbital trajectories. And then detonates that system. That kind of EMP pulse can destroy the satellite's electronics.

The next-generation biological solar cell could be useful in green energy. And in the power supply of manned space stations

The long-term space mission that is limited inside the asteroid belt is also challenging. The spacecraft or space stations can travel between Mars and earth by using ion motors that get their electricity from solar panels. Also, the Mars- and moon stations can use solar panels for energy production. The same technology that is used in Mars or Moon stations can use in the isolated research stations on Earth. 

And places like Antarctica can use to develop this kind of technology. The idea is that those stations are used to test things like closed-cycle life-support. If food can produce at the moon station, that radically decreases its costs. And moon station can use to test the technology, that is needed for the Mars station. 

There is a possibility that spacecraft or space station gets at least part of their electricity from a biological source. In this case, biological solar cells can use along with regular solar panels. When we think about the use of biological solar panels at isolated places, that thing makes the station more energy efficient than before. Even in the dark seasons the ability to recycle part of the energy that is used in the greenhouse. 

That is producing food is making the system more energy efficient. The solar-power can use along with things like wind generators. And in the summertime in Antarctica, the operators can fix wind generators when solar panels are used to make electricity. Also, biological solar panels can recycle part of the energy that is used in greenhouses. 

But the thing is that the living solar cells that are photosynthetic and can create electricity from living vegetables are an interesting alternative. In that case, the same system can create electricity, it can clean the air by using photosynthesis. And that kind of living solar cell can also offer nutrients for the spacecraft's or space station's crew. That thing allows using limited space more effectively than otherwise. 

Developing green energy is important. And always at the beginning of the system is in small-scale systems. But then those systems can escalate to everyday use.
