Good Cheap Materials for Batteries

[Bret Cahill]

1. NaCl

2. NVPS (Not very pure Si)

3. Carbon

4. Polymers and cheap metals.

Remember, the efficiency doesn't need to be all that great.

Why not make a battery out of chocolate?
That way, when the battery runs down, you can
dispose of it by eating it.

Of course, the downside is your tractor
will attract ants.

Funny.

Thanks for the chuckle,

Not if the tractor is also made out of chocolate.

Picture the (Australian only?) Cadbury's choclate commercial
"wouldn't it be nice..."

We still waiting for those "thermodynamic limits" that can help
account for the energy density of batteries being less than 10% of
liquid fuels.

Engineers pretty much know the reasons a diesel or gas turbine or
Stirling operate at less than 50% Carnot but designers apparently are
staggering around in the dark when it comes to energy density of
batteries.

You have to consider whole-cycle cost, including
disposal cost.

I don't think you'd be willing to eat barbed wire.

On the other hand, a Lindt Excellence 9V battery
might be a whole 'nother story.

Because they already tried that. Which is why the people with
*Engineering brains*, rather than scientoon salesman gimmicks,
invented BIO-DIESEL, neo Wind Energy, Adaptive PV Cells,
POST-FORD Batteries, POST-McDonald's Holograms, Post-AT&T Fiber
Optics,
HDTV[]. CD+rw, DVD-stack, RISC++, XML, USB, AAVs, AUVs, and
Drones for the
idgits.
