Mint Energy has developed an extremely useful concept design, that could help spell the end of dead batteries. Their Rechargeable Battery combines the battery itself, and the charching mechanism all within the standard shape of an AA battery. Half of the object is filled with a rechargeable Ni-nH battery, and the other half contains a magnet based charger, that you simply shake to charge.

Someone watched “The Matrix” too many times. Humans converting food into kinetic energy are even less efficient than mixing together chemicals, so this is yet another way to spend money and harm the environment while feeling good about oneself.
Fortunately, the effect will be just about negligible.
