Why water has the highest specific heat capacity of any liquid ? 

How atoms carry thermal energy?  

We must look into atom's structure first.

Atom is made from a positive charged core (name it C), an positive charged inner shell (I) connected to an negative charged outer shell (O), and a floating negative charged fluid (F). The Core and floating fluid are constantly oscillating under unbalanced attraction and repulsion force from the double shells..

The amount of charge of the C, I, O and F defined atom's properties.

Metal atoms have stronger I and weak O, therefore have more floating fluid and it is locked closer to the shell shell. Makes metals a better conductor.

Oxygen atoms have bigger C, weak I, strong O and no floating fluid. therefore C can oscillate at same voltage but carry more energy, and oxygen can be more active.

I suspect that oxygen's  resonance frequency matches atoms on the sun. The sun could be made from oxygen.

This is the basic ideas. My math sucks, please help me to improve the theory if you can. 

Energy and Atom

Nowadays energy storage is a hot topic. But do we know how atoms store energy and what exactly is energy? We don't. 

It is important to realize that in physics today, we have no knowledge of what energy is. We do not have a picture that energy comes in little blobs of a definite amount. It is not that way. -Feynman

We know atoms are made from oppositely charged particles, we know atoms are constantly vibrating.

Vibrating charged particles/atoms carry oscillating electrostatic force, is that energy? Does hotter matter/atom carry more energy and vibrate faster?

Scientists talk about fusion energy, why can't they fusion electron and proton to produce energy? How much energy can be released by fusion electron and proton? What is preventing them from colliding under tremendous Coulomb's force? It is the strongest attraction force existing in the universe and it is the only force existing between electron and proton in atoms. 

The present theory of the atomic structure is heavily flawed. If atoms are formed from the electron clouding/waving/orbiting around the nucleus, what happens when gas molecules collide? What happens when diamond cuts glass? What is preventing the electron cloud/wave/orbit crashing into the nucleus? How can atoms form into solid and incompressible matters?

My Atomic Structure Theory

A positively charged core with a positive charged inner shell connected to a negatively charged outer shell, and a floating negatively charged fluid. The core and the fluid are constantly oscillating at the radius direction due to the attraction force from the inner shell and the repulsion force from the outer shell.

Facts we know so far are:

1. Atom must be able to attract other atoms in order to form into matter.

2. Atoms must have an incompressible surface/shell/boundary to be able to form into solid matter.  

3. Hardest matter is formed from atoms that have the strongest attraction force/binding force. 

4. Atom carries the oscillating electrostatic force/heat/thermal energy, so it must have moving parts that can carry kinetic energy and potential energy. 

5. At room temperature, gas matter atoms repel each other. Liquid matter atoms attract each other weakly. Solid matter atoms attract each other strongly.

6. Temperature is an internal property of the matter, it is proportional to the thermal energy density/AC voltage of the matter. All matters are formed from atoms, all atoms are constantly oscillating and carrying alternating electrostatic force. The current flow direction is the heat flow direction. Thus the second law of thermodynamics.

7. Atoms are perpetual machines, AC generators, transformers.

8. Atoms carry the code of life.
