How much electricity do you want from the pedal machine? If you want just enough for a few LED lights and want to spend the hours pedaling, maybe might be worth it.
I think it is a waste of time and resources to generate any decent amount of electricity with pedal power. It's possible, but quite involved. You are far better off hooking the bike to the appliance and grind your grain with a mill. Pump some water, hook it to a sharpening wheel, hook it to a makeshift washing machine. ...................
If you think you can make an 8 ft diameter wheel that runs perfectly straight and spins perfectly and most likely has a fly wheel that is also perfectly true, and you want to spend a lot of hours manually spinning electricity, you might get enough electric to run a few things.
I think finding a temp job for a week and getting a solar panel or two then instead of pedaling electricity you spend time with other chores and let the sun do the generating. 25 years of sun electricity for a weeks work in 2018.

So chains come in two basic varieties, metric and "standard".
Pitch on Standard chains come in 1/8" increments and the first number equals how many '1/8's. So #40,#41,#42,#410, etc. are all 1/2' pitch (same as bicycle chain).
A standard size frequently used on go-carts, etc. is a #35 which has a 3/8 pitch , that's probably what you have. Measure it from the middle of one tooth to the middle of the next.
If it's smaller than 3/8 pitch, then it's probably a 8mm pitch metric chain.

However, since you are searching for the chain without any samples to work with... I'd suggest finding a local bearing distributor and take your sprocket to their counter and get their help in sussing out what pitch it is.
Bonus: they can sell you the parts you need! I'd also go armed with the shaft dimension for the bike end (use calipers or a micrometer) so you can get the correct bore on the hub to fit the bike.
You might also find roller chain at a GOOD hardware store, or an outdoor power repair shop, that you might be able to try some different chains to your sprocket...but they won't likely have the bike side sprocket you want.
So, you'd just be "showrooming" to purchase online later...
If you happen to find some chain, sometimes the plates are stamped with the pitch, and that's a great help...
If you measure ten links and divide the result by 10 you can increase your precision, and maybe tell the difference between metric and standard pitches that are close in size.

You need as good an efficiency as it is really hard work to make a useful amount of power. The average person can do 200 watts for a short time and maybe 50 for a more sustained period.

They are inedible!!!
The flower petals have spikes on them, which makes them about like eating thistles. They are fibrous, so take a lot of chewing.
With the petals being too fibrous to eat, the rest of the flower is even more fibrous. Still with the same spikes as the rest of the plant.
And that resinous taste!!! It is super concentrated in the flowers. A disgusting taste that I don't want anywhere near my mouth.
I've tried eating a lot of things that are supposedly edible, and I might eat them if I was hungry. However sunroot flowers are something that I would not attempt to eat no matter how hungry I was. Bleck. Ugh. Yuck. Spitting.
