Re: Powering LEDs from raindrops.
Quantifying "100 LED bulbs" is not very helpful. Single LEDs typically need 3.5 to 5 volts at currents of 10 mA-50 mA.
What matters is how LONG can a single LED bulb with these specs be powered.
Watts = volts x amps.
Watt-hours (or watt-seconds) is the metric we need, not volts. Watts x hrs.
I hate reading science articles written by/for non engineers.
