In order to create a \”lightning bolt\” for their test, the team first generated an alternating current through a transformer. They then channeled that current between a gap that was a little under an inch thick, surging 200,000 volts — well within the average strength of a typical lightning strike — in the form of a bolt of electricity. The signal was then transferred into another controlling transformer, where it was able to charge the battery of a Nokia Lumia 925.
