At this point, Air-gen generates “a sustained voltage of around 0.5 volts across a 7-micrometre-thick film, with a current density of around 17 microamperes per square centimeter,” enough power to run small electronics.
17 μA is perhaps the current drawn when the device is off.
They also expect it to soon provide power for mobile phones the user will no longer need to recharge.
1 cm² for 17 μA. Say you only charge the phone at 100mA at 5V. That would require 5 square meters of this stuff (63 square feet).
