I've been playing chemistry for a while and battery technology interrests me
but it's a lot more complex/challenging than I'd hoped !

As a side experiment / novelty / curiosity
(I already have graphite levitating above NdFeB magnets)
I fancy building a solid state cell

there is a lot of free energy nonsense about

but in there is some useful info.

I already have zinc and copper cans, graphite and magnesium rods and quite a few chemicals
and provided not too toxic/explosive/expensive I'll consider any materials.

So, I have two questions;

1) anyone here got any advice / hints / tips on cell construction/composition?
especially regarding longevity ?

2) I will need a low voltage, low power, long life, demo load,
I've so far considered an LED (boring) and a small d.c. motor (not long life)
so any suggestions for an interresting load ?

A cheap 433 MHz radio module uses very little power and gives off a lot of short audible transmissions if you live in a suitable area.

Geiger counter?

a geiger tube would require an inverter which is too many parts for a LOW power load

433 MHz transmissions .. I'd need a receiver for it I suppose ?

any other ideas ?

a small windmill replica... visually attractive and appealing, and relaxing too... you can even make it so it has a don quichotte style

They are $0.5 to $1 on ebay. You can also make one yourself.

I have a 'thing' about windmill models;
when my son was in lower school I helped him to make a windmill
we used balsa wood etc. and put a small dc motor driving the blades via balsa pulley gearing.
The teacher said that it was too good so it must be a kit and marked him down! Grrr!!!!

Maybe I need to build one to overcome my 'thing'

................................................. .................................................. .
since posting the question I've been looking at the 'EZ Spin' motor on YouTube

can be 3D printed and has been designed for crystal cell demo's ..
I may get my son to print the 6-pole version one ... thinking ...

--------------------------------------------- ---------------------------------------
for the actual crystal (solid state) cell I'm considering a cell made of
Magnesium/Magnesium Nitrate/Silver Nitrate/Silver ... a very expensive primary cell

but âˆ’2.372V and +0.7996V = over 3V per cell and pretty/shiny.
Need to do some small scale tests first.

I'm glad of having hit the 'thing' ;)

I've done a little more reading and thinking and realised that
crystal cell batteries rely on water (of crystalisation or hygroscopic or deliquescent absorbtion)
Real crystals don't conduct electricity ! (some exotic synthetic crystaline structures can)
so I'm putting this project on hold for now,
until I come accross dry electrolytic crystal structures that I can make.

... seems I will not be the saviour of mankind with my zero-point energy, perpetual motion, environmentally sound anti-gravity time-warping batteries ...
maybe I'll build a crystal radio instead .....

Sulaiman why give up so quick theres a 1000 light bulb prototypes to make

On a serious note, all energy seems to come from the sun, so pertual motion machines etc are in the same bucket as fusion research, but the only difference is one knows they are hitting a brick wall

If there is a AC source that could be classed as renewable, a liquid electyle could be used, with the liquid none reactive with the electrode, the ac source should stop the corrosive effects, when you draw current, they might start to corrode, but then use a diode to stop the positive or forward direction of voltage of the AC source, and you should be left a back EMF.

and a liquid turns solid at colder temptures, I think it has to do with energy or something, I don't know maybe Ge/Se/As etc, with small pockets of liquid.

Any others?
