Put That Cup of Coffee to Real Use and Have it Charge Your Device With the onE Puck

onE Puck

Kickstarter sure does bring some fascinating products to the attention of potential buyers. The newest one to catch our eyes is the Epiphany onE Puck charger. What makes this different from any other conventional charger is that this one requires no wall outlet for its power. Ever. The onE Puck only requires your hot cup of coffee or cold glass of beer to make sure your device never goes dead again. Cool, right? 

Using a simple heat engine, the charger takes either the hot or cold energy and magically transforms it into battery juice for your device. Since I don’t know the science behind it, I feel like Steve Jobs when I say, “it just works.”

They are on Kickstarter for $115, but once the early bird-type of discounted chargers are gone, they will sell at retail for $150+. Yes, that seems quite steep for a charger, but then again, the idea of having a charger that will never need a wall outlet is pretty cool. Check out their page and the video below for more info.

    Scientifically, this gadget can’t charge a battery with 5.3 watt-hours capacity, more than 2 percent!

    would this work if I put the hot side face down on a heating vent/radiator that happens to be next to my desk? I’m heating my house anyway…..

  • PseudoK

    But I still need electricity to heat my coffee or cool my beer.

  • Robocop

    This works differentiating the temperature between the sides. So if you placed the Blue side (cold) on a cooler metal table and then put your tea or coffee on the coaster, the temperature changes would create more power. Similarly if you put an ice cold beer/soda/water, etc on the blue side while the RED (hot) side was on your leg or inside of a warmer apartment, it would be more powerful. Yes $115 is a lot but the majority of it is going to their sister project that is working on water power using this tech to aid 3rd world countries…in a sense you donate $75 to their charity and get a cool $40 charger

    Or……you could plug it into a wall for pennies

    I don’t know why this is posted here, none of us sit in Starbucks with our Macbooks & iPhones.

    • sbux!

      Wait… You dont?
      And here i thought i was so cool sitting here in bux with my macbook doing something that is undoubtedly very important…hence the reason that i chose starbucks and their hard wooden chairs over sitting on my warm couch at home.

      i would be the hippest hipster in starbucks with this. getting it just so i can permanently sit there with my super smug face

    If this uses a heat engine, it is moving heat to make electrons flow. If this is the case it is either moving energy to or from the beverage you have sitting on it. Therefore, if you have coffee on it, it will take heat away from the cup, if it is a “cold beer” it will move heat energy to the beer. This will make you glass of whatever colder or hotter quicker. So this is not a good buy to me.

    • Droidzilla

      I believe this uses a liquid medium to drive pistons that rotate a standard generator. Hardly very efficient, but it ought not make your beer warm.

  • http://profiles.google.com/potentialender james netzer

    Like I’ll really put my coffee tethered to my phone. Just waiting for it to spill on it.

  • mustbepbs

    This is why I hate Kickstarter. It gives naive people with disposable income an outlet to fund morons with bad ideas.

    • Droidzilla

      At least it keeps it all in a closed loop.

      • mustbepbs

        Not if I have to read about it in my news feeds.

  • http://twitter.com/NathanWright11 Nathan Wright

    It’s been a long time since I took physics, but I’m pretty sure “cold energy” isn’t a thing.

    • Droidzilla

      Well, technically “hot” and “cold” are just energy states relative to surroundings, right?

  • Chris

    An iPhone on the picture? No wonder that thing is overpriced. They probably slap an “i” in front of the name when it is ready for release.

  • http://www.deathbycone.com Jared Kotoff

    How does it make energy from cold drinks???

    • http://twitter.com/starnovsky Stan Tarnovsky

      Same way as it takes it from hot ones. Device works on temperature difference between room and the drink. Works both ways.

  • Superdroid

    Well if you are a hockey player you can charge your phone while playing hockey. That’s cool.

  • EvanTheGamer

    Not sure I’m buying this concept. Hmm…and not sure if it’s worth $115.

  • Charlie Ham

    Id rather pay the 150 for it then get the device next to it freefor two years

  • Justin Howard

    This is a cool concept but I think I’ll stick with my Targus portable charger, on a full charge it charges my RAZR twice. My phone is plugged into the wall most of the time anyway so

  • http://twitter.com/hightweetts Tareck A

    Sounds like a disaster waiting to happen. I wonder how many people will get water damage from this.

  • joejoe5709

    Far too expensive for what it does, but this is a very cool idea. Agreed – they should find a way to use body heat!

  • Jonathan

    I bet it works using something like this: http://en.m.wikipedia.org/wiki/Thermoelectric_generator

    • Jonathan

      Sorry for the mobile link. On my Nexus 10, as always.

      Unless he discovered some amazing new physics, which I’m guessing he didn’t because he would be getting a big fat check from a large company or the government and not be on Kickstarter, you’re probably right. With that in mind, I don’t know how the inventor expects this to work.

      The amount of energy produced is proportional to the temperature delta between the hot and cold side of the device. These devices are used on spacecraft with hot 30-40C electronics on one side and -269C space on the other side and they still don’t produce that much energy relative to that application.

      Also consider the huge thermal resistance between the cup bottom and surface of the device… this thing would be lucky to power a digital watch.

      Well, if it does get off the ground, make sure to place the blue side of the puck in a bed of ice, use an aluminum coffee mug with no insulation on the bottom, place it on the red side, then press down hard to reduce thermal resistance the entire time.

      • CapnShiner

        Maybe you’re supposed to use thermal grease on the bottom of the mug like a CPU heatsink.

    • Luxferro

      It clearly states it uses a sterling engine. http://en.wikipedia.org/wiki/Stirling_engine

      How it works, I have no idea.

  • termiNader

    What a terrible price point. Make it at most $75

  • Thomas

    F that cheap ass Pebble Watch when you got cool stuff like this !!! /throws blank check ;)

  • http://www.facebook.com/jason.geiger.35 Jason Geiger

    Cool concept, but putting a candle on it seems like it would work better. I only charge my phone while I sleep so wouldn’t be functional for me.

  • JBartcaps

    I don’t drink coffee.

  • Tom Z

    This reminds me of the BioLite Camp Stove that will charge your devices via USB.

    • Gadgetskopf

      Got one of these. Love it.

  • http://www.facebook.com/people/Dominick-White/642535026 Dominick White

    Cool idea but not worth the price

  • Kumar

    What about Cofee Spills?

    • mustbepbs

      Well he DID mention the $500 paper weight.

  • Austin00

    Put a candle on it then it can charge forever!!

    • Austin Warren

      But the heat doesn’t travel the the bottom of it. The surface of whatever you place on it needs to be heated.

  • XvierX

    Find a way to turn my body heat into a charger and I’ll buy.

    • http://www.facebook.com/profile.php?id=505617824 Yannick Mark Perryman

      Maybe you didn’t see the Matrix..

  • Trevor

    Cool concept, but definitely not worth $150 to me. I’ll stick to electrical outlets for the time being.

  • moelsen8

    If this was $20 I’d be all over it. Cool stuff.

    • Austin Warren

      “help the world” but let’s make it expensive first. Solar energy is cheap. This should be too.

      • michael arazan

        And you can probably sit on it or put it under your arm for 30 minutes or more or other heat points using your body to warm the device for a charge. While camping you can foil wrap rocks or potatoes in the fire and then set it on it. Has a lot of heat transference potentials other than hot mugs of coffee

    • http://twitter.com/morpheus282 William

      I’d go as high as $45. $115 is a bit ridiculous. It would take several 55 gallon drums of coffee to pay for itself at that price.

  • R

    lame

  • Will

    But, how much juice will it put out per cup/bottle?

  • MotoRulz

    $150 really? So your coffee stays warm for what.. 5 minutes? This is sooo not worth it.

    • Austin Warren

      My coffee stays warm for a while. What are you smoking?

      • MotoRulz

        Mine does to when I drink it right out of the coffee pot..

        • EvanTheGamer

          LOL!

    • Chris Hollenbeck

      Maybe if it worked off body heat……

    • EvanTheGamer

      It’s $115 though..

    • http://twitter.com/MI95SHO MI95SHO

      Unless your coffee cup is super efficient, your loosing the thermal energy out the bottom/sides of the glass anyway. Shouldn’t reduce the time it stays warm by much.

      • WAldenIV

        The bigger issue is how many people need to charge their phone early in the day when coffee is most prevalent? The idea of using this at home with a cold beer makes a lot more sense to me.
