What is the best way to generate and store power from short bursts of a spinning wheel? Answered

I have a wheel that spins up to 508RPM for a period of approx 20 seconds. It does this every 2 minutes for approx 20 mins then it stays motionless for up to one hour.

How can I generate and store enough power to power a wireless router and slr digital camera charger?

The budget is up to $1000 USD.


So, have the generator charge something like this and then have the supercapacitor feed into a resistor to charge a 12v lead acid battery, which in turn connects to a DC>AC inverter, which will give you 110v mains power to connect to the router and camera charger.

What is this wheel and what makes it spin?
If you put load on it you'll affect whatever it is.


From that,

Starting question:

How much power does the camera and router take ?

You have, as I read it 200seconds every 3600 to generate enough juice to run the pieces you want, so you need the power rating of the pieces X 18 (making ZERO allowance for losses) from your generator. So, if the load is "20W", you need 400W of generating/storage capacity, rounding up again, say 500W.

So your wheel has to deliver 3/4 of a horsepower - and that's making some rule of thumb allowances for losses, and thats for a constant load of 20W.
