Hi, Something I have always wished someone else would try. :)
1) wrap a coil around a strong magnet (or maybe just an Iron rod?), that is aligned with the Earth's magnetic field, such that the Earth's field lines are concentrated in the body of the magnet (or Iron rod). 2) Attach a capacitor to the coil such the resonant frequency of the tank circuit matches the Schumann resonance. 3) See if any energy can be harvested from the circuit. Regards, Robin van Spaandonk Drive your electric car every second day and recharge it from solar panels, on the roof of your home, on the alternate days. The other days, drive your spouses car, and do the same with it. "Charge when the Sun shines".
