    Yeah that’s my point, the energy you can actually harvest is ridiculously small. Even if it was slowly charging a capacitor with this harvested power and saving it for later use, how often can i use the switch before depleting the energy faster than it charges? “oh sorry, you’ll have to wait 5min to turn on your lights again, It’s not quite charged enough”
