dead battery forever

[AntonioLao]

Why do cellphones need to be recharged frequently? Why can one charged battery last a lifetime? The surprising answer is intimately connected to the different phases of Gibbs free energy for most chemical reactions. These distinct stages of change of Gibbs free energy are the differences between enthalpy and the product of entropy and absolute temperature: G=H-TS. It indicates that all thermodynamic processes tend to strive toward the dynamic equilibrium condition such that Gibbs free energy is a minimum approaching zero, implying that enthalpy (H) is always slightly greater than the product of entropy (S) and absolute temperature (T). However, at absolute zero the enthalpy is exactly equal to the Gibbs free energy regardless of the corresponding values of the entropy.

On the one hand, the enthalpy is given by the sum of internal energy (U) and the product of absolute pressure (p) and oriented volume (V) which could be negative depending on the underlying physical geometric topology. If the oriented volume is negative and the magnitude of the product of p and V is equal to the absolute value of U then the enthalpy is exactly zero. The consequence is that G is identically zero and the cellphone can never be recharged and the final outcome is a dead battery forever. On the other hand, if the absolute pressure is zero regardless of the positive or negative value of the oriented volume, the Gibbs free energy is identically equal to the internal energy: G=U. Wherever and whenever this happens, G becomes the zero-point energy of quantum vacuum fluctuations of squares of energy. Consequently, the physical geometry becomes a hyperbolic Bolyai-Lobachevsky topology of negative curvatures, contrasting the Riemannian topology of Einstein’s general relativity of positive curvatures.

Okay, Antonio,

How is it, that I have a solar calculator that I acquired 25 years ago for $12.00, and the little marvel still works like a charm, and I assure you that living with me is not easy.

Why can we not have a cell phone with a solar battery?

Perhaps it could not be turned on all of the time, but it could serve for emergency calls out, (as folks with radio phones in the bush for years had regular standby and broadcast times) and limited standby, made known to close acquaintances.

I own a cell phone that is only used as indicated above, as I, for one, do not choose to be on call to the world at large.

Unless you are 'inner circle', you can call the 'Bionic B----', who is on standby 24/7/365. And yes, I am so quaint that I actually check my e-mail and messages.

'Twitter' or twitterpated has an entirely different context with me, lol...

Back to batteries. Why no solar cell phones, or have I just not noticed their existence? (Yes, she lives in a world of her own imagining, and it's not half-bad...)

Label, you will have to use moonlight to charge your calculator for the next 6 months. Just be careful not to divide by zero, as always.

Stop right there! The keyword I think is the word 'solar' which is equivalent to the word 'light' or electromagnetic radiation. Light is really pure energy and the purest light travels at lightspeed in absolute zero of temperature. All impure lights travel at lesser speed where and when they interact with matter at much higher absolute temperatures and much less efficiencies. A battery made of pure light (photons) instead of electrons will I think last forever. And this is true also for cellphones or computers that run using the amplified stimulated coherent light of lasers. These are future technologies waiting to be realized.
