That will please the battery makers if it works ......

looks like a scam to me. Reminds me of the Tesla scam now making the rounds via the internet.

The technique will work but there is little evidence that there is sufficient stray power to accomplish storing enough energy to power anything that requires frequent power like a radio or flashlight. Perhaps a clock or something like that might be feasible.

I worked on top secret military stuff years ago that used radio beams to store power in sensor devices. It was a focused beam of high power however/

The headline is typical reporter hyperbole, but in the article they talk about very low power applications like clocks and remote-controls. Hardly 'eliminating batteries'.

Sort of like the atmosphere clocks that are self-winding using changing atmospheric pressure. Cool idea, but for very limited applications.

Nice article Chris, this only the beginning of what I see as leading us to
the eventual source of all our power and energy requirements of the future.
There's an immense amount of free energy around us and in space just waiting
for us to develop the technology to tap into it. In two hundred years time
humans will look back at us and think how fairly primitive we were then with
regards to the technology we used to generate our power.

there is no abundance of free power. Solar is the most intense and it is of low quality (temperature) and therefore will be difficult to harness efficiently.

Solar power is yesterdays discovery....we've only just turned the fourth corner
on the Chiliagon of scientific discoveries yet to be made. A hell of
a lot of corners yet to be turned here, a hell of a lot of new discoveries just
waiting to be made....I very much suspect I know what one of them will be?

I have wondered from time to time whether our bodies generate or could be made to generate a mild electrical current that could power certain low power devices such as cell phones, watches and etc.

I have a backpack with solar cells which load a battery I can use to recharge my cell phone. But I think it's not strong enough to recharge my Sony camera, also the cables provided do not fit the camera, so I cannot even try.

You been watching The Matrix?

You should be good to go for about 500W :-)

If you get a multimeter out you can see that your body does generate some voltage. However, it's rather small. From the left pointer finger to the right pointer finger I'm generating about 25 mV right now.
