You'll find in practice they can afford a cheap led light and battery what they need is a charger for their phone (And clean water/micro-nutrients/medicine/sewage~=clean water) And wow, potato batteries are a scam. Fool I am. So boiling them won't release more energy to electricity... I guess... I'll need to sit down and work it out. I don't get why a cheaper fluid that doesn't rot won't work ok then. Why is there no web page explaining this Sci Fair scam. Why a potato over salty water? Or a steak. Or a lump of dirt. What's the relationship between a potato having energy and the fact it's used in potato batteries.
