I think it's obvious that if your lap top is fully charged it must weigh more than if it had no charge because technically it is carrying more power but I'm not sure if penguins have knees

E=mc2 , where E is energy, m is mass, and c is the speed of light in a vacuum (fixed).

So from the equation the answer is yes.

Things a bit slow at Greens? Try this for a conversation starter,

"Women talk more - 20,000 words a day compared with 7,000 for the average man - and they talk twice as fast"

For most housebound men it simply means buying a longer garden hose.

What productive use/s could the information be put to though?

I know your still sleeping, just wanted you to know, you are the first person today to put a smile on my face

Just for you half Pint!

Assuming the battery is completely sealed (ie no vents), then there would be no weight gain. For every electron that flows into the battery, one electron flows out.

In any case the total mass of electrons transferred for each ampere-hour of charge is ...

(1 ampere hour) / (elementary charge) x (electron mass) = 20.5 micrograms

It is quite a conundrum, Billeeeeeee, now Ihave to decide if I power up the laptop before or after I take off on my adventure.
Life's questions are always there for contemplation. Certainly given me something to think about over the next couple of days!!!

What about the penguins

dorian · Guru

Edit:

I realise it's only a bit of fun, but AFAICT the "energy-mass equivalence" weight gain for a fully charged house battery would be about 50 nanograms.

(12 volts x 100 ampere hours) / (the speed of light squared) = 48 nanograms

If you could convert 1 gram of mass completely into energy, you could power 3300 average NSW homes for a full year.

1 gram x (the speed of light squared) = 2.85 megawatt years

(1 gram x (the speed of light squared)) / (7500 kilowatt hours) = 3329

Way too hard to even think about here at the Garden of Eden, Uncle Fester. If I were you I would go have a nap instead.

SnowT · Guru

just wondering if that is different for the different types of batteries..

ie Lead Acid compared to Lithium[LiFePO4y]

As Lithium suck up more power do they gain more weight..?? or is that more relevant to State of charge..?

Penguins don't have knees, I don' think- but then again i have been wrong once!

Greetings thedes, I can say this with confidence, !!Yes!!, Penguins do have knees, I'm very excited about this, also thedes, do you think the humble Penguins, is Evolving into a bird of flight, or is the penguin Evolving from a bird, of flight to a bird that only walks and not fly's..?????? May I also say this,,??? Rocky Lizard , has been studying the white breasted blue eyed Atlantic Penguin, for 7 years , I believe,,,???? stay excited Nutters, Billeeeeeee

Hmmm interesting question. A bit like one I ponder sometimes, if a tanker truck has to deliver a load of Helium, does the truck get lighter the more Helium it takes aboard?
