What engineers are just not trying to screw the solar panels. Mobile phones, laptops and even cars - all of this, with varying degrees, is able to replenish electrical power at the expense of the sun. However, it is recognized that only a few of these devices are doomed to success. Whether the invention of Iqua will receive due distribution is only time will tell.

This is the usual bluetooth headset, equipped with a small element that generates electric current from solar energy. The idea, as I personally think, is very worthy. The only question is how long the headset will have to be charged and how long it will last from a single charge, because bluetooth is very voracious.
At the moment, the exact specifications of the device are unknown, but it is possible that they will soon be announced by the manufacturer.
