Have you seen the price of the boat anodes!! I might start making them lol.
I am working on a chemical process with a chemist from SA, its simple in design and not greatly efficient, but we hope to turn the black gunk back into MNO2.
Apart from my little spin off project we are looking for ways to recycle the black mix back into MNO2 so the only wastes in theory should be the paper/steel and waste solutions, most of the waste solution we can recover alot of the chemicals from.
I know it seems pointless but sometimes I learn most from this kind of thing, also those graphite rods sell really well cleaned up! very useful and saves my MMO electrodes for special electrolysis, you can get the MMO coated Tungsten sheets easy from the states but they seem hard to find in the UK.
My set has Rhodium in the mix and makes great chlorates/perchlorates (not that I would make those
).
I also want to mess with salt bridges and split cells, I have a few ideas I want to try out so I can make a decent split cell. I have 10 old car batteries awaiting some looking at, I read a paper a few weeks ago that has given me an idea for a lead acid battery.
The other new project I need more info on before I mention it or John will be all over me in a flash lol, I need to double check the paper but if its correct then a home made hydrogen fuel cell might be possible. As soon as I know if the patent and paper are legit I will get his opinion on it, handy having a Chemist on an electronics forum!
Building my new fume cabinet next week, I need a bigger one and want a bit more height to it. I couldnt afford a new one so decided to custom make one.
Oh and the project I did last week I might post up with pics, I made a tiny solar panel with microscope slides, its pathetic in output but interesting to do.
