Unless you’ve lived under a rock, you’ve probably seen terrible images coming out of Ukraine. Broken houses and apartments, injured people (especially children) and any other image of death and destruction has been heartbreaking. But there is some good news coming out of the country earlier this month that shows that it is quite difficult to get a solar power plant out.
At first glance, the damage to the Merefa Solar Generation Power Plant looks horrible. There are solar panels and parts of solar panels everywhere and a large crater on the ground deep enough for a man to get on, and then some. He appears to have detonated a bomb, in large part because he detonated a bomb. It was connected to a Russian ballistic missile that had been aimed at the plant.
You can see both damage and surveillance images of the missile attack itself in this video:
“This type of damage is typical of a rocket or projectile hitting solar power plants in Ukraine,” Ignatiev said. “It should be noted that the station was built in a swampy area with geogrids, so the station’s support structures were damaged locally as a result of the missile attack.”
But according to PV Magazine, it’s hard to keep a good solar plant low. The equipment at the 3.9-megawatt plant went out quickly, disconnected the rows of damaged cells, and reconnected as many work rows as they could. The result? 1.8 megawatts of solar energy still enters the Ukrainian grid, which is almost half of the energy originally produced by the plant.
“Staff were able to disconnect the damaged chains and the 1.8 MW of power now provides clean, green electricity to the grid,” said Stanislav Ignatiev, general manager of the facility’s owner, Solar Generation.
The Merefa plant is located about 30 kilometers south of Kharkiv and supplies clean energy to the city of Merefa. For nerds and solar professionals, it has 325 W Talesun photovoltaic modules and 27 kW Fronius ECO 27.0-3-S inverters.
One key thing we can learn from this missile attack is how robust and resilient solar power generation can be. By being able to lick and go halfway, this solar power plant is capable of doing something that most fossil fuel plants probably would not be able to do after a missile attack. If this had been a coal or natural gas plant, things like refrigerant loops, fuel supply lines and other critical components would probably mean that even in a multi-turbine plant, little or no electricity could leave the plant during weeks. or months.
For solar plants? Computers can regenerate at least some power, if not most. Then, repairs can be made while the rest of the plant continues to supply vital electricity to the civilian population. Add to that the fact that there are usually a large number of plants spread over a wider geographical area, and it is difficult not only for war, but also for natural disasters to completely eliminate electricity from an area.
Therefore, we have another reason why renewable energy can be good for national security, and this is as true in any other country as in Ukraine.

This self-induced magnetic field interacts with the electric current flowing from the anode to the cathode (through the plasma) to produce an electromagnetic force (Lorentz) that pushes the plasma out of the motor, creating thrust.
Can Earth’s magnetic field be used for propulsion?
If you want something to levitate, you have to generate a non-uniform magnetic field. A large magnet on the ground is one way to do this, but it leads to instability. And you should have the magnet with you wherever you go, so you have to drag a large magnet on the ground to blow up something small.

Using solar energy is a great way to help reduce the carbon footprint that is harmful to the environment. It also does not emit greenhouse gases and other toxic chemicals. Solar energy is a self-sufficient renewable energy resource.
The mere act of accelerating something in a certain direction (the rifle bullet or the hot gases of an escape rocket) creates a force just as it acts in the opposite direction (Newton’s third law). This reaction is what drives a spacecraft up or through space, regardless of the presence of earth or atmosphere.
What propulsion is used in space?
What do rockets use for space propulsion? The rocket’s main engines use a combination of liquid hydrogen and liquid oxygen. Hydrogen has the lowest molecular weight of any known substance, making it ideal for maintaining the weight of a relatively small rocket. When combined with liquid oxygen, hydrogen creates the most efficient thrust of any rocket propellant.
What does NASA use for propulsion?
Interplanetary vehicles also use mostly chemical rockets, although some have used ion propellants and Hall effect propellants (two different types of electric propulsion) with great success.
What is used for thrust in space?
NASA is analyzing two types of nuclear propulsion systems: nuclear electric propulsion and nuclear thermal propulsion. Nuclear electric propulsion systems use propellants much more efficiently than chemical rockets, but they provide little thrust.
Can you have propulsion in space?
As the exhaust gases go in one direction, the rocket goes in the other to keep the total momentum of the system constant. This change in thrust gives the rocket the “push” to move forward. We call this thrust the thrust of the rocket, that is, the force exerted on the rocket.
How does a spaceship accelerate in space?
There is no atmosphere in the outer space, so turbines and propellers cannot operate. This explains why a rocket works in space but a turbine engine or propeller does not work. There are two main categories of rocket engines; liquid rockets and solid rockets.
How fast do spaceships accelerate in space?
A rocket provides the means to accelerate a spaceship. Like the jet engine of an airplane, a rocket creates too much thrust to take advantage of Sir Isaac Newton’s third law (see above).
How does a spaceship turn in space?
To reach the minimum altitude required to orbit the Earth, the space shuttle must accelerate from zero to 8,000 meters per second (almost 18,000 miles per hour) in eight and a half minutes.
How does a space shuttle accelerate?
To rotate your spaceship, shoot a pair of side point thrusters near the opposite sides of the spaceship. To stop spinning, fire in the opposite direction.
What propels a rocket ship?
The main propulsion system consists of the external tank (ET) and the main engines of the space shuttle (SSMEs). This system, together with the Solid Rocket Boosters (SRB), provides the force (thrust) needed to accelerate to the speed of approximately 7.85 km / s required to reach orbit.
What makes a rocket ship move up?
In a rocket engine, fuel and a source of oxygen, called an oxidizer, are mixed and blown up in a combustion chamber. Combustion produces a hot exhaust that passes through a nozzle to accelerate the flow and produce thrust.
What makes rocket ships fly?
Thrust must be greater than weight A rocket is launched when the force of the thrust pushing it upwards is greater than the force of the weight due to gravity downwards. This unbalanced force causes a rocket to accelerate upwards.
How do spaceships propel themselves?
Like most engines, rockets burn fuel. Most rocket engines convert fuel into hot gas. The engine expels the gas from the back. The gas advances the rocket.
