We move to the lab to get a better idea about the parameters of the earth battery between the metals. I will also conduct a load test from the water battery we create

Overview
We use filtered water as our conducting substance. All the components will be tested to each other and look at surface area and what impact it has for electrical potential and current.

Load test with the evaluation board. the voltage drop is not high which indicates that not all power available is used by the circuit. That need to be considered when we deploy that in the ground and have to match it to the load.

First Summary
In this simplistic replication we can establish that various metals to each other have
different potential levels. Our test is performed with filtered water and not with distilled
water. The result is almost the same. With standard test probes we measure the
resistance with over 1 mOhm which is expected from demineralised water. The picture is
different when we use copper stripes which brings down the resistance to 35K. Here
the electrodes influence the resistance by creating a stronger electron flow. Our Earth
battery is a water battery. No electrolyte is in use to perform a galvanic reaction to
increase the potential and current. Magnesium is however high reactive and is creating
an oxide and therefore electron flow in water. Lead plates are used in wet cells for the
automotive industry. In order to increase the energy density we have to decrease
the resistance without adding salt or acids. We will focus on that in the next video.
