PeltierBeer

    Guinness is supposed to be drunk at room temp not 8-10 Deg C.

      Your research should include the side of the can, where it says "Serve extra cold".

      bah!

      drinking warm guiness is like having sex with the lights off, you miss all the best bits.

      You can check their website then.

      Note, IE. Ireland. The real stuff.

      Enjoy in the pub or at home in cans or bottles. Chilled, of course. We recommend 6C for GUINNESS® Draught and a cooler 3.5C for GUINNESS® Draught Extra Cold. Your GUINNESS® Draught in cans should be chilled for a minimum of three hours before serving, and chilling for even longer will simply add to the ultimate experience.

      Guinness is supposed to be drunk however the fuck you enjoy it most.

      If you like it boiling, while you're juggling knives, and with three shots of ammonia added, then that's the proper way for YOU to drink guiness.

    Power over CAT5 is quite handy, 20m of network cable should be enough to get me out in the sun with cold beer.

    Hi, MacDork. Yes, your understanding of thermodynamics is probably ok. It's your ability to read the article and grok it that's coming up short.

    He used a Peltier junction. Look it up. It's an active, solid-state, heat transfer device. It can move heat against the thermal gradient, when supplied with power.

    IOW, run current through a Peltier and one side gets colder than ambient, and the other side gets warmer. Reverse the current, reverse the effect. Add a fan to the hot side to get rid of the heat, because they are limited to a max temp differential between the sides.

  9. As a beer geek... by Hayzeus · · Score: 5, Informative
    The temperature beer should be served at depends on the beer. With the exeption of some barleywines, beer should never be served warm or even room temperature.

    Ales in the british tradition are typically served at "cellar" temps -- around 55F-60F. Continental lagers are best a little colder but generally not below 45F. A few belgian styles do better even colder, but never ice cold (38-45F).

    If served ice cold, beer tends to lose most of it's flavor and seems thinner. The same is also true to a lesser extent with increasing carbonation. In the case of an american pilsener like bud, you're not missing much if the beer is ice cold. In the case of a fine czech pilsener like Budvar, you'd be missing a lot.

    This thing couldn't work in a million years.

    The thermometer isn't in the beer, it's hooked directly to the copper plate atop the peltier device.

    Without a crystal goblet and gobs of thermal goop, he's going to cool his thermometer probe and some air and not much else. Actually, he should just leave the beer in the can. Aluminum has a thermal conductivity of 205 W/m-K, and glass does 0.8 W/m-K. The thinner can* and 250X increase in k will make his project more successful, but still a candidate for /. troll of the year.

    I'd be willing to bet that the metal rails of that "caffetiere" are transmitting more heat to the sides of the glass than the copper plate is taking from the base.

    * - say the base of his glass is 4 mm thick, and the can is 0.2 mm thick (it could be less), then the glass will have a thermal conductance of 200 W/K and the can will have a thermal conductance of 1.03e6 W/K.
