I bought it on Amazon. I will power it via solar.
I have 5 bar of shs to play with.
I will ask the cad crew to conjure up a turbine and then make it all from stainless and running at 300 / 500 bar.
Then we should get some tidy centrifugal going.
The wife and I have been discussing seting up something like this for the kids to watch TV or play video games.
Hook it up like solar to a back up battery bank.
They make alternators that you attach where the rear tire goes now if im not mistaken. Im not electrical savy but was looking at something similar here for my property but we have great wind gusts so I’m going to let nature do it with a windmill instead . More costly but less of a risk for me.
You can also put a full bridge rectifier on the output from a brushless DC bike motor (wheel) and pull electrickery that way (generates 3-phase AC till you rectify it).
don’t remember. I was presumably trying to get from 60rpm to 1800 rpm so 30:1 would seem appropriate. looks to be more than that. which might have been deliberate (might have been targeting alternator’s sweet spot).
might also be that it was actually the first alternator pictured that required 1800rpm (to work without 12V on the stator)…
