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

I should be able to mod my bike to charge my phone.

Add some solar cells, too.

` it probably has an output wattage and amperage`
lol.
A x V = W
but yeah

You should just go nuclear

I just mean it has information somewhere on it 😛

The iPhone 8 has a 1960mAh battery

So, at 3.7 volts that is ...

7.4 Wh

WAIT WHAT

That'sa tiny battery

Wait, is that wrong?

Someone give specs please

apparently it's 1821mAH

I guess it is a couple of generations old, but even so

small battery, Apple

Okay, let's just round it up

Let's say you ned 10Wh

Let's see how much you would have to pedal.

Dang, I can't find how much energy that thing generates.

He has it in the video briefly.
