Letters to a friend _ Commercial Flywheel Energy System

 Hello friend(s),


To understand the potential energy of a weighted flywheel, let's look at how a commercial flywheel energy system works. The energy available is calculated in this fashion. 
Kinetic energy, or your power out, is determined by the angular momentum of the flywheel.
Angular momentum is mass times velocity times the radius of the flywheel.
  We can use this to size the flywheel we will need to create torque from the 12V DC motor to the generator circuit.

Military dictatorship USA

The Turd and his military dictatorship have begun the invasion of North America. Military assets have been and are continuing to be deployed at strategic points. The public announcement of the military annexation of the southern border and the buildup of armor, serves a few purposes. We have effectively sealed the border, now no one here will be able to escape to the south. The armor battalions can maneuver both to the south and attack Mexico, while providing military support to the Gestapo that is seizing control of Los Angeles. Large scale concentration camps can be established in Southern California on the illegally annexed land.    lot of fuckery    Resistance means more than just sitting down when the shooting starts. I am not a willing sacrifice, and you should not be either. Martyrdom is death. The death of democratic people is their goal, their primary objective. They will laugh as they shoot you point blank. They want you to sit down, and die.    W...

Fighting Nazis

Fighting Nazis. I have been knocking Nazis down, for many years now. My favorite conflicts have been at the many metal shows that I've seen. It is great fun, to knock a Nazi down. Make 'em cry...    The band Dark Angel was opening for Slayer. It is very aggressive music and a favorite of the NeoNazis. Lots of targets, much fun to be had. There was one of the enemy on the dance floor; you know, with the swastika tattoo, confederate flag on the denim vest. A real piece of shit.     This Nazi kept spinning around and the crowd kept falling back. So I made a run at him. I saw the blade in his hand, just as he lunged at me. He tried to open my forearm, but he missed and hurt the person next to me. There was blood spray on my shirt. Shortly after that, he was disarmed and dog piled. Carried out on a stretcher. The beat down was well deserved. fuck Nazis #antifascism

Nazis are masters of violence.

Nazis are masters of violence.  That is their strength, their power.    Fear of violence, fear of humiliation, fear of death; that is how the nazis work, fear is a tool. They thrive when they terrorize. And they are counting on our acceptance, the acceptance of extermination. That is why they always say that they are not nazis; that the real Nazis are the antifascists. Or, just because you don't like someone that doesn't make them a Nazi...      right?    So no one will notice the Gestapo in our streets? Or tanks rolling down the streets of the nation's Capitol? That is the purpose of the lies, to blind you to the truth of what is actually occurring. The Nazis are here.     We have become a surveillance state similar to Palestine, just a larger prison with more guns. Be cautious with your communications, we are all under constant surveillance. Our country is occupied by a foreign backed military dictatorship. We are all in danger....
