Water to Ice expansion creates MASSIVE pressure, like crush a submarine 100x over sort of pressure.

It set me to thinking; "Well.., geez! That's an

*awful*lot of energy. Where does it come from?"

So I did some novice calculations (which I've written in average-joe English steps below so if you follow along you will understand rather than glaze over as with most scientific papers. I encourage you to do so in order for my thoughts to have meaning)...

-Pounds of pressure per square inch exerted by expanding ice: 43,511 lbs (19,736 Kg)

-1 inch = 2.54 cm (Converting to metric)

**-Energy needed to change 1 kg of water by 1 degree Celsius = 4200 joules**(To melt or to freeze, you need to move that much energy.)

-Weight of 2.54 cubic cm of water = 0.00254 Kg

(runs the math)

**-2.54 cubic cm requires 10.67 joules to freeze from 1 degree Celcius to 0.**

(runs more math)

-Force exerted by the expansion of 2.54 cubic cm of water freezing to ice =

**19,736.26 Kg pressure**

-Distance traveled (You need to know distance and time traveled to make use of work/force calculations.)

ice grows by about 9 percent from liquid = 2.8 mm (rough estimate)

-Energy required to lift 19736.26 Kg over 2.8 mm =

**542 joules**

Soooo... While it takes about

**11 joules**of energy to change water 1 degree C between liquid and frozen, doing so generates

**542 joules**of energy.

Melting would take another 11 joules of energy, which would drop the weight, releasing the potential energy.

Rinse & repeat.

Now.., engineering complexities aside.., (it takes some work to visualize mechanisms which could aim and capture that energy in a useful form) that seems like an absolutely

*massive*return on energy investment. Completely out of proportion.

Is this an example of Free Energy?

*Extreme*thermodynamic disobeyence?

Why have I never heard about this before? You'd think the magnet wheel people would be all over it.

What am I missing?

Or...

Is this an example of genuine free energy? -Which we have all apparently missed for some reason?
