I suspect I can light an LED from local RF fields. Gotta try that some
time. Free illumination!

A crystal set can be very loud in a city, near an AM station. Must be
milliwatts with a longwire antenna. Some clever circuit might harvest
several stations.

A good LED is visible in room light at 1 uA, just over a uW. And
barely visible in the dark at 1 nA.
