Battery Science

[SpeleoTrog]

On the way out of a dig today, the discharged drill battery was definitely heavier than on the way in when fully charged.

I've made a scientific deduction therefore and have decided that, when all the charged electrons shot out into the drill, they must have been replaced by stray gravitons rushing in to fill the gap.
I'm going to write this up into a more detailed thsis and publish it soon


(Of course, it may just have been my arm getting tired on the way out)

The Lithium Irons flatten the Lithium so it looks bigger. Things that look bigger feel heavier.

Is it not just covered in mud? No idea if your dig is muddy, just a random guess based on previous experience..

Sedimentary, my dear Watson.

Do you have steel toecap wellies? All that electricity gets converted to magnetism in the motor and therefore the drill is attracted to your wellies.

Clearly, a Nobel Prize awaits you guys.  :bow: :bow: :bow:

Clearly, the added mass is through the capture of "Dark Energy". Obvious, really, that dark energy and dark matter should be found in caves rather than in space!

More likely the discharged battery is acting like a dowsing rod and being attracted to the huge chamber below your dig.

It's quite simple really.

Lithium is an anti-depressent. When the battery is full it will therefore feel much lighter and easy going. When run down it will feel much the same as any of is in the same situation, heavy, sluggish & hard to move.

You're stealing my jokes again, Mark.

Sedimentary, my dear Watson.

You're stealing my jokes again, Mark.

Hey, we're a double act!

 

[maxf]

is your battery half full or half empty ?

 

[Rhys]

Sedimentary, my dear Watson.

You're stealing my jokes again, Mark.

Hey, we're a double act!

I seem to recall that our double act was once dubbed "T**t and C**t" by someone who didn't appreciate our humour. I never worked out which one you were...

Simple, the energy (E) in the battery has been converted into mass (m) according to Einstein's famous equation:

E = mc?

where c is a consonant.

The battery chemistry is important as lead acid batteries gain weight faster than lithium ones due to the density of lead (11.34 g/cm?) as opposed to lithium (0.5 g/cm?).

Which must prove that volts (v) are a vowel?

Should we consult Carol Vorderman?

Consult Carol Vorderman - that doesn't add up.

Anyway, it's a well known fact that all the difficult software is thrown to the outer tracks of a hard drive by centripetal force. I think that this backs up the premiss of the OP regarding batteries cos it's all to to with electrons.
