Knut Karlsen has come out with both of genius, as well as a simple idea – batteries, which are capable charge without any additional devices.

In order to realize its intention, Knuts use of flexible solar energy accumulators, and some wires from the damaged Nikon lens. So far, though such a charging mode has been developed exclusively for C-size batteries, but it is reported that the production will soon fall into the size of other devices.
Among other things, the new battery takes exactly the same spot as us usual. It is expected that in future, such devices will be equipped with the capacity of the producer.
