Прототип генерирует ток около 150 мА при напряжении 5 Вольт. Если подобный генератор сделать более компактным и вмонтировать в мобильный телефон или планшет, то с его помощью можно будет круглосуточно подзаряжать аккумулятор.

The prototype generates a current of 150 mA at a voltage of 5 volts. If such a generator to make a more compact and integrated into a mobile phone or tablet, then it can be used to recharge the battery around the clock.
