I will go try figure out how much would 1 energy credit be worth

10min with my quik math

Not sure tho

It would take an hour about to charge it then.

But is my theory possible?

Definitely

2000mah @ 3.7V is about 10Wh

You need to figure out what it can do and also what it's worth - they're slightly different

If it draws 10 watt, it would take an hour to charge from totally empty to full

That's not terrible

So, you can produce more, but you can't "squeeze" it into the battery faster than that

I mean, it's exercise 😛

I really should learn how to ride a bike

pedaling produces up to 200W, but you only need 10

can you store the rest?

So, you need to have patience, but you will not have to exert a lot of energy.

You can basically have a reclining bike, read a magazine, and if you lightly pedal, like the grannies at the gym, you can charge your phone, easily.

By this guy's estimates, you're doing worse in terms of cost and footprint

It will still take you an hour, but the maximum draw of your phon eis 10W, so if you hook it up to your bike, you can ride around and listen to music as long as you want.

Imagine being in the wilderness, you are out of battery, but have your bike with you. Just ride around for an hour and the battery will be full.

I think that would actually be really, really cool.

Also, you can screw an adapter into a light bulb and convert it to usb.

That shouldn't take me longer than an hour or so to solder.

So you can charge 20 phones in one hour.

I wonder how to set up my brainchild currency system

I just need to build something similar for a bike lamp, and that's it.

Cuz I am definitely onto something here

Oil values are dropping rn

Dang, I will actually see if I can sell this in Europe.

So one hour divided by 20 to get time it takes to make enough electricity to charge one phone

Yes, I think so.

Those are just rough estimates, but a biker produces about 200W of energy.

Apparently, the charging draw for an iPhone is about 10W.

Energy loses and so on...

And phone is Wh not just W but yeah

One joule is worth this much 0.0000115522875816

as of current oil prices

You can probably use your regular Apple charger. Even if you pedal too slowly, it shouldn't bother the adapter.
