Enocean has been making battery free wireless light switches for almost 15 years. I've personally used them for about 8 years and love them. They're a lot more expensive then the $1 quote in the article but still cheaper than an electrician. They work with a strike to a piezoelectric element to make energy and transmit the signal.

Oh nice. My parent's doorbell is a wireless one and I thought it was a trick. That they hid the battery and sold it with false advertising.
