The Mint Battery is a concept gadget that explores the use of kinetic energy to keep an AA battery charged. Rather than using energy from a wall socket or solar panel the Mint Battery looks in to the idea of being able to shake the battery to create charge.
To fit everything needed to make it work the Shakenergy Mint Battery is about half the capacity of a regular rechargeable battery (maybe 750mAh – 1000mAh). What the concept shows is the charging unit being placed at the bottom of the cylinder and the half sized battery sitting just above that.
As it’s only a concept it is unknown if the Shakenergy will ever be made. Various factors such as charge time also need to be taken in to consideration. Still, a quite cool idea though regardless of it being practical or not.
