Why not just use coconuts and a bicycle, like the professor did on Gilligan's Island?
Joking aside, a bicycle with a generator would be more efficient, and importantly more practical. Efficiency also exposes that energy conservation can not be overcome with fads. Just my humble opinion.
This is an obvious hoax. The device harvests rotational energy by interaction with a gyro which freely rotates inside the ball? What powers the gyro? 6 watts? How long can it output 6 watts? How long to purify a cup of water at room temperature with 6 watts? As for emergency light with energy harvesting, I have a LED flashlight with a crank generator that requires just a few turns to run for at least 15 minutes. Much more practical than playing soccer in the dark to recharge a ball, then plug in the light. It also is small enough to fit in a pocket or a desk drawer, not so with a soccer ball. As for this not being a hoax since it has been shown in the media already, since when can we assume that this does not mean it is a hoax?
At first, I figured this was going to be easy to make fun of...people who don't have electricity now have a means to charge their phones. ???
Practially, though, a means to sterilize water would have a huge impact on many people. For us with a limitless supply of safe water at our fingertips, it's had to imagine many people have no safe water or any means to make it safe. Being able to charge a Steri-pen or equivalent would be a leap forward.
@robatnorcross: Actually, it's assembled in the U.S., and is intended for distribution in the developing world. Did you even read the article? It's a actually a neat idea. It's not an April Fools joke; Popular Mechanics covered it in 2010, and the BBC covered it last year. I think it's a creative concept, and one that makes a lot of sense.
What a great way to call attention to energy harvesting. It's also interesting that the developers are involved in a Kickstarter program. We're seeing Kickstarter get mentioned a lot these days. Just in the past few days I've heard it mentioned in a breathalyzer application for iPhones and in a new electronic basketball (we'll have an article about that one in the next few days).
Yes, that was another point that I didn't mention in the story, but also it could be good for many practical applications for anyone, which is why they are doing the Kickstarter campaign. Alison even shared a story of when she was at a music festival and needed to charge her iPhone and wished she'd had a SOCCKET to do so. I myself go camping a lot and find myself out of battery for my devices all the time. I have a charger in my VW van but it saps the van's battery. so I don't like to use it too much. A SOCCKET would be perfect. I'm sure this technology can be applicable to all sorts of playing balls in the future.
I think something like this is great for anybody and not just people or countries with energy poverty. Imagine just having it around for charging your phone after a game or having a light when walking back to your car after a game. But one question I have is would a country like North Korea jail anyone with possesion of the ball? I think in my case I would like to see it come in a basketball.
With erupting concern over police brutality, law enforcement agencies are turning to body-worn cameras to collect evidence and protect police and suspects. But how do they work? And are they even really effective?
A half century ago, cars were still built by people, not robots. Even on some of the country’s longest assembly lines, human workers installed windows, doors, hoods, engines, windshields, and batteries, with no robotic aid.
DuPont's Hytrel elastomer long used in automotive applications has been used to improve the way marine mooring lines are connected to things like fish farms, oil & gas installations, buoys, and wave energy devices. The new bellow design of the Dynamic Tethers wave protection system acts like a shock absorber, reducing peak loads as much as 70%.
