CibbuanoKinetic energy batteries are getting even better

"That's awesome."
Rolex came out with a self-winding watch that used the motion of your arm swinging to keep the watch wound.
Then they used the movement of your arm to charge a capacitor, which powers a quartz crystal, allowing the watch to last even longer.
Even better, railway stations are looking at harnessing the vibrational energy of commuters' footsteps to power lighting.
M2E Power is going one step further, making more efficient microgenerators to power batteries.
It's for a Defense prize... the DoD has been looking for an answer to its battery problem: each soldier carries a helluva lotta batteries to power all the equipment they carry. Since they are instructed to use fully charged batteries in the field, this means that there's piles and piles of batteries being discarded.
From the article:
"According to M2E Power's website, its system is five to seven times more powerful than existing applications of the technology. So soldiers using the M2E microgenerator should have an easily renewable source of power.
"With the flashlight and other applications of this technology, the magnet has to pass all the way through the coil before it can generate electricity," says Regan Rowe, director of business development for M2E Power. "Our core innovation is that the magnet starts to generate electricity after it passes the width of just one wire." "
