Some people in devaloping countries still can’t have electricity for their basic needs like turning on a lamp.
ESPIN is an innovative portable electricity generator using the flow of water to produce a reasonable voltage for personal usages. Rivers are the main focus of ESPIN’s design but there’s the possibility of using any sort of hydraulic flow like the waste waters of factories.
It’s is easy to use, fill the weight bag with stones, tie the ESPIN’s cable/rope to it, and put it in the river. When the blades start spinning the other side of the cable/rope has your electricity.
