Iron Battery - What Worked and What Didn't

Image
When I left the Iron Redox Flow Battery overnight connected to the AA battery, and switched on the pumps again in the morning, I immediately noticed brown liquid flowing through the pipe into the tank, so I asked AI what happened (novice here too !!😇), then I had to understand how exactly a battery works. So buck up, now we are going into depths of battery science, but first the basic- Current is how many electrons can you push in the circuit per second, voltage is how hard you can push them, current density is how many electrons can pass through battery electrode per unit area per second. The higher the current density; faster the battery charges, lower the current density; slower the battery charges. But remember, per unit area, so the total amount of current flowing in the battery is dependent on area of the electrode also. A good battery crams as many electrons possible as quickly as possible in a unit area of the electrode. For instance, when you connect a fast/turbo charger to y...

Guide to Making you own Iron Battery

So, when looking for a cheaper alternative to Vanadium batteries, I stumbled upon all iron chemistry,  the absolute cheapest battery chemistry possible, using only iron, the most mined element from Earth's crust. The metal so cheap that its literally the basis of human civilization. No need to heat the battery, no need to check supply chains, Iron is so abundant that you can find it wherever humans are. I was convinced, Gemini gave me the broke college kid solution. So I ordered Iron chloride from the internet, you know how much lab grade 500g highest purity cost me ? Rs 800 ($8), that's pennies as compared to Vanadium. So before I give you step by step procedure of building you own Iron Redox Flow Battery we need to understand how it works. Working of Iron Redox Flow Battery Similar to Vanadium, Iron redox flow battery has iron on both sides, on both sides it is in Fe2+ state, when it charges on the positive side it converts Fe2+ to Fe3+ (loses 1 electron) and on the negative ...

Iron-Chromium, The Natural Choice. Or Is It ?

 I'll be honest, I didn't dream of Iron Chromium Redox flow battery in my dreams, nor did I have any secret information from NASA. I did what any other 22 year old would, ask Gemini about it. If you ask Gemini or ChatGPT about VRFBs, there are high chances that it will suggest alternate chemistries also. Now that can be a good thing or a bad thing. If you know a little bit electrochemistry, it would spit out a very obvious answer. If you don't, you'll go down the same rabbit hole I did. AI doesn't know your intentions. So it acts as the most efficient information summarizer, and that's great, if you just want information, not if you want action. So one of the first alternatives to VRFBs Gemini suggested was Iron - Chromium, and it made a lot of sense because Iron and Chromium are commodity metals, Iron is literally the most mined metal on earth and chromium comes third [ source ]. Their commodity prices are - Iron - $110 per ton   (at the time of writing) Chromi...

The AI Data Center Power Problem And Who's Going to Solve It

Image
 I love AI, its the perfect expert and assistant, I always wished for. I am very sure so do most of its users, yes there are some problems with it. But I am sure world's best engineers sitting in these companies will solve them. But here's a problem 99% of coders cannot possibly solve in their cubicles, and it decides how your favorite AI behaves, power supply. Let's talk about Claude, because I am using Claude nowadays, but I have seen a very similar pattern in Google's Gemini Pro (student version) and ChatGPT. So feel free to generalize this issue Free User Experience If you have asked any AI model to perform complex tasks for you, or make complex decisions, most AI models take time, somewhere between a few seconds to sometimes Claude taking minutes to draft documents. Not a dealbreaker, but I wish it was faster, since I am so used to speed now. Also as a non-premium user of any of the AI models, I have also seen that they hit a limit. In many cases for premium users ...
