We were able to do aluminium casting ~640-660C using a furnace that we made from a broken vacuum cleaner and a bucket with a hole in it. :D https://wiki.london.hackspace.org.uk/view/Project:GingeryFurnace Using a smaller 24V fan as the air input, with a renewably-charged battery, and sustainably-farmed charcoal, the whole system was carbon neutral :D So 570C for Zn4Sb3 is perfectly feasible. :D 3 comments
It would be interesting. :D I've never worked with German Silver before. :D I read how the recipe for the metal was nearly lost due to the anti-German feeling after WW2, but i've never played with it yet. :D Plus the press-fit design for the plug-caps could be pressed from sheet metal. The hardware and jigs to do that are really simple, and they've fallen out of patent decades ago. :D If they produce enough power, then attach them to meshnet nodes, and put them everywhere. :D |

its worth a try - at very least if the cells work you should be able to get enough solar power to charge batteries that could run all the routers / networking / telecoms hardware in the hackspace, independently of UK Power Networks (good for resilience if there are power cuts)
