How does a office worker make money without working in a gold mine or an oil rig

Because labour has value

Yes, and labor can produce electricity.

And labour can be traded

I think I will make a bike that can charge a battery.

The concept is workable

I think it will be like that

Let's see if someone has already made something like that

So what, you work in an office and get paid in batteries?

@Undead Mockingbird someone has

@Ronano credit card

No physical currency

Energy credits

In the end, only energy has value.

Big reform

@Undead Mockingbird yes

Because, anything you might want is related to energy.

This is like that Black Mirror episode

Oil-energy

If you eat food, it's to create energy.

Gold-labour-energy

If you pay someone, you pay them to exert energy and spend time.

Just make energy currency then. Go the the roots

Energy is the ultimate value in the universe.

That's true, but people usually differentiate the 'type' of energy based on its context

Most people do not think of it that way

As in

"I'm going to work" doesn't usually translate to "I'm going to go and expend energy"

oil currently is ultimate currency.
together with gold and silver.

@Undead Mockingbird How much cycling to charge my phone?

I think I might get such an adapter for my bike, because then I can drive around and charge my iPad.

I'm not sure. That's a good question.

you can caculate it if you want.

aye, it probably has an output wattage and amperage

the motor it uses

I think I can build this myself.

Instead of putting in a light bulb, you can convert your bike to produce electricity.

Most bikes, especially in europe, already have a dynamo powered light.

If you just remove the bulb, you can solder connectors that lead to a battery
