3. ### Complex Dielectric Permittivity

Complex Dielectric Permittivity!!! Homework Statement Calculate the power dissipated per unit cycle in a dielectric medium per unit volume in terms of the dielectric loss and the strength of the electric field The previous question was: Why does the dielectric permittivity of a material in...
4. ### Casimir's Energy

Sorry if i posted this in the wrong section. Iv just read about the casimir force which can cause 2 parallel plates 2 move towards each other in empty space. Where does the plates kinetic energy come from?
5. ### Another free energy proposal

A friend of mine asked me where the energy comes from in this setup: Imagine a fan/windmill inside a box. The fan is only allowed 2 turn clockwise and is connected to an axel which exits the box. The atmosphere will keep the air inside the box at, well, atmospheric temperateure. Every so...
6. ### The Future is written?

Lets say we mastered near lightspeed travel and instantaneous communication using quantum teleportation. Then we send the spaceship off to someplace 1 lightyear away. It turns around and for a brief moment travels twords earth at near lightspeed. During this moment the spaceship asks earth how...
