It only works because the LC circuit has a high "Q" and it peaks up at resonant frequency, at the expense of current. It is sort of like a torque convertor for electricity. Now in most applications a minimum voltage is required and you will counter the small current by using a capacitor to accumulate power, at a usable voltage, until you have enough to briefly do something. I would make a YouTube video if I could be arsed, but way to busy right now.
