How much electricity can be made from one gallon of electrons?

how heavy would one pound of electrons be?

We can know all electrons are in the gallon if we give up any hope of knowing the momentum of the gallon.

a pound

Even if you managed to isolate the electrons and store then inside a bucket, their repulsion force would make they pew pew all over the place

...

depends on the pound used

all the atoms in a bucket of water have electrons.
so fill the 1 gallon bucket with water and then measure the electricity

Im pretty sure if you gathered a gallon of electrons in one place they would produce a godawfully huge explosion

How large a place are we talking?

Don't know about gallons but a liter has about 7.4e20 coulombs I think.
Now this:
A cube of (0.1*0.1*0.1)m^3 contains 1 liter.
The diameter of an electron is about 6e-15 m.
What is the pressure inside the cube?

A place with the volume of a gallon, maybe?

Easy enough if we use an old school definition of electron radius.

1 gallon = 0.0243 m^2

The classical electron radius (or Lorentz radius -- obviously with modern physiques we understand the electron to be a point charge) of an electron is = 2.82E-15 m.

Plugging that into the volume of a sphere equation returns an electron "volume" of 1.18E-14 m^2.

(0.0243 m^2) / (1.18x10^-14 m^2) =
2.057E12 electrons in one gallon.

(2.057E12 electrons) * (electron charge) =
3.3E-7 Joules.

What amount of electricity this could generate requires more info, but if we moved each electron in the gallon across a potential difference of 1 volt, then the total voltage would be simply: 2.057E12 eV.
