This circuit converts surrounding radio frequency waves to electric power. It can provide 40 Volts at 10 Watts indefinitely. The output power can be improved playing with the antenna. Placing the antenna near large metal objects gives more power. [...]

This is a Constant Current Source LED Driver, When the LED driver Upper-NPN is driven by a voltage thru 4.7K the LED lights up. Assume that the Lower-NPN at bottom is absent. The current via LED and NPN is limited by R. 20mA may be ok 15mA even better. Or LED blows even transistor goes.
