50 Carbon Arc Electrodes 5/16 By 12 Inch Rod Rods Reviews

“Great deal, less than $20 with shipping and they lack the copper coating (just want the carbon). Grinding these into powder and pyrolysing it via salt water elecrolysis with high current AC over a metal screen (not sure if that's a common technique, discovered it by accident a couple months back] to form activated carbon powder without needing to build a blast furnace or use strong acids/bases) for use in a paste that will go into homemade electric double layer capacitors (ultracapacitors) that work at excessively high voltages for EDLCs based on a technique I found tonight. The torroids ordered the other day are probably going to be useless until I find a new experiment for them, as I've decided to go with an even cheaper and more stable solution than 210KVA worth of transformers - 210KVA worth of ultracaps for about a 1 hour runtime (approx 3024 Farads @ 500V) - with modern ultracapacitors this comes to a bit over $18,000 if bought at wholesale prices (due to the cost of stacking 2-2.5V ultracapacitors to work with 500 volts, 3024F @ 2-2.5V is only about $40-60). Due to the significant cost difference (these rods, a few household chemicals and some flashing from home depot should be enough to meet my needs) I might end up selling my version of these HV ultracaps.”
