How to Recycle Scrap Metal into Electricity - Rust Power!
Yes, you read it right! It’s actually very easy to recycle scrap metal into electricity. The amount of energy locked up in plain old metal may surprise you. Think, how much you can get from a simple dry cell, a flashlight battery. Yet, it uses only its thin zinc case as fuel. In numbers, a pound of zinc (in the right type cell) will produce about .61 kilowatt-hours (kwh) of electricity; scrap iron .56 and aluminum 3.7 kwh/lb. That means that a 2,654 pound Chrysler le Baron (if at least 80% of it is really steel) should have about 1.189 megawatt-hours of hidden power.
The only difference between the zinc fuel in a dry cell and the zinc coating on a galvanized nail… is its shape! So in order to extract the hidden power in metals, all you need to do is build some simple homemade batteries, and hook them directly to your radio, TV, or other DC appliance. For AC appliances just insert a commercial inverter that converts your free DC into AC. It’s as simple as that! I ran my boom box for 8 straight hours on gum wrappers!
