The total mass in the system is constant.
As the reactor gives off energy so it reduces in mass, and as the battery charges it takes on the mass.

Not it is not, that's the whole point. The entire reason for having the equaiton 'E=MC2' is to tell us the ratio between mass and energy. You can turn mass into energy and energy into mass. The amount of energy you get from a given mass is described by E=MC2.

Nuclear reactors work by changing mass into energy. Batteries work by re-aranging mass (i.e. by changing the location of electrons etc.) but they don't change mass into energy. The former is a much much more energy dense process (millions of times more) which is why you can get a massive amount of power from a small box.

The mass of a nuclear reaction is decidely not constant, that's how it works.

To put it another way...the reactor turns mass into energy. That energy is used to produce light in the flashlight. I.e. it goes somewhere. If the mass was constant, you'd be getting something for nothing. I.e. you'd get the energy from the light and get to keep all your mass...

Dazzle goes by Einsteins laws of physics and you're stuck in the past with Newton's playground stuff.

No, I think that mass is turned into energy which flits off as light, or is stored in the batteries of the flashlight.

Like I said, you can't get more energy and keep the same mass.

Yes, it does. Despite the fact you're sticking stuff together, the resultant fusion products have lower mass than the two parts you started with. The same holds as you stick heavier and heavier atoms together until you get to Iron-56, at which point you have to add energy in order to get heavier atoms.

That's why Fusion only provides energy with elements lighter than Iron-56 and Fission only provides energy with elements heavier than Iron-56. Both will work with any element, but outside those limits you'll have to add energy.

The reactor has to get lighter...like I said. Not sure what you're getting at.

That's not what Einstein said, according to E=mc2 a battery gains mass when it is charged up. You may not believe his theories* but that's what the question asked about. It doesn't matter how the energy is stored it still creates mass.

* I don't blame you, he's been proved wrong before but in this case has been proved right. Well, I guess until Quantum physics can tell us why he's wrong.
