"It has NO batteries" and then proceeds to show the plates of the "battery". Idk, if it worked good with ocean water, maybe, but you could practically power a led with a potato so I see it more as a science demonstration, it's cool, but not the greatest thing since sliced bread. I wonder what the life expectancy of the electrode plates are.
There's another one out there that shows one with larger electrodes, I think they were rated for appox 250 total hours run time and replacement plates for about 4 bucks.
