That would reduce the total current. How fast is the process? Maybe rim rotation on nylon rollers but not a wheel. Steel bits in an anodizing bath make big holes in the aluminum (not certain about brass nipples). Aluminum nipples would anodize into the rim. Somehow you have to attach an electrode to the rim. -- JS |

It's impossilbe to get less than 100A at 240V service in a US house these days; 200 is a lot more common in new construction. Well, it was just my gut feeling. My house is about 50 years old. New houses might be different. My brother should know. He's an electrician. -- JS |

I looked around and I see Aussie electric cookers rated at 8.7 KWm Australian standard seems to be 230 VAC -10% +6% so a worst case would be feeding the cooker with 207VAC or about 43 amps. Likely the house Entrance is at least double that so if you turn the lights out you probably have enough power to do the rims :-) Might be cheaper to just plan on buying a new rim every once in a while :-) I came to the same conclusion. Similar economics to bitcoins? (price roughly compares with the electricity cost required to mine one) |

Similar economics to bitcoins? (price roughly compares with the electricity cost required to mine one) Same economics of everything really. For example gold miners are currently processing one ton of material to yield 1.6 grams of raw gold, add processing, transit and certification costs to that. And yet the market is active.
