Day 491, Battery talk time

Today let's talk about what we can learn from history.

On the left:

Smart phone that has been on battery for almost two days.

On the right:

Legacy technology that doesn't use a battery yet doesn't need winding.

Embarrassing story to endear the speaker to the audience:

There have been times where I have forgotten to charge my phone, oh boy did I feel a schmuck.

The 'but wait' moment:

But wait.  Isn't there a better way, a way that means it doesn't matter if we forget to charge our phones?

The proposition:

Of course there is, why not harness the natural energy of the environment?  Kinetic energy available to all.

The reveal:

We should be using recharging technology like we have in the self-winding watch.*

That's what we can learn from history.

Applause, etc.

End of talk.** 

* Modern phone design starts with the case, what is fashionable for the type of phone and what its ability to dissipate heat is.  This determines the maximum power consumption in Watts that the phone can have.  Each feature of the phone has a cost in Watts and the premium features will be at the head of the queue, the techies then have to determine how to allocate resources across the other features.  There may be a bun-fight over how these are distributed and it will be a compromise.  The battery has a major part to play in this and the amount of space that a mechanical recharging component takes up would be of major importance.

** This talk lasted well within the twenty minutes allocated, so plenty of battery life left here.
