Beanzawave: The World's Smallest Microwave


Conventional microwaves are some of the biggest energy hogs in the house, using 750 to 1,100  watts of power when in use—more than both refrigerators (725 watts) and washing machines  (350 to 500 watts). But the Heinz Beanzawave, billed as world's smallest microwave, could cut the energy necessary to warm up small items like cups of soup and tea.

The Beanzawave, which measures just 7.4 inches tall by 6.2 inches wide and 5.9 inches deep, doesn't even need to be plugged into an electrical outlet.  The device contains a USB port, so mid-afternoon snacks can be heated up at the computer without expending excess power. In the future, Heinz might experiment with lithium ion batteries—making the Beanzawave ideal for camping trips. Heinz claims that snacks can be warmed in under a minute thanks to intense heating action from a combination of cell phone and radio frequencies.

The mini microwave is being developed as a partner to Heinz Snap Pots, baked beans in single-serving containers. The Snap Pots, available in the U.K., fit perfectly into the Beanzawave. But the $160 device will only be released commercially if consumer feedback is positive and if component prices drop in the near future. At its current price, the Beanzawave isn't much cheaper than a conventional microwave.

    This is Awesome ! The market potential for this item for folks who also live "off the grid", campers and folks living the RV lifetsyle would be ENORMOUS ! The ability to heat canned foods, or heat up a cup of water on nothing but 5 volts would be incredible ! I have a camper that uses nothing but a 12 volt solar panel system with a motorcycle battery for storage. I have been searching endlessly for some means to heat canned good and cups of water without an open flame gas cooker in the camper, or without other types of portable 12 volt portable cookers that quickly drain my 12 volt solar storage battery. This item could change lives for people in remote areas who need a quick hot meal, who have no substantial electricity. GO FOR IT ! I WANT ONE NOWWWWW ! Even at $160

    This is great! I've been wanting someone to come up with a mini, mini microwave for years. I want one for my back porch (shaped like a birdhouse?) and one to put next to my recliner (shaped like a candle?).  I would absolutely pay the $160 for it....especially if they could come in "designer" shapes.  I just HATE cool coffee and tea....I want them hot....and having one of these next to me so I don't have to keep getting up and reheating would be wonderful!  I'm not being totally lazy, I have some physical problems and this would be just "what the Dr. ordered"!  I hope you get a lot of requests for them so they will become available....even if they have to look like the prototype. But, I think my suggestions have merit & would be more appealing to the ladies.  Thank you.

    It's something new! USB-connected microwave! It's great if it really saves energy.

    '''Your compaint about the power used by a microwave oven doesn't make sense. A refrigerator (725 wattes is on 24 hours a day, so it uses 18 kilowatts of electricity a day. A microwave oven (1000 watts) is used let's say 30 minutes a day, so its total electricity consumption is 0.5 kilowatts!""
    His was better. An average fridge uses about 18cents a day max, not $1.80 as your numbers.

    Wow! I want one of these.Check this out.How about two vertical perforated microwaveable tubes on a small round stand in which you can insert 2 hot dogs to heat up.Would go good with the beans.Food for thought.I have only one question, how hot does the food get?

    This is clearly a viral marketing gimmick for Heinz. I don't even believe that this thing works, given that even Only Technology News can only put out 4.5W. Isn't it pretty, though? Why don't we get Heinz blue cans here in North America? I guess we need a picture to tell us what Money exchange.

  • Jim Arthur

    What a pretty appearance. That is real amazing combination of science & technology. Undoubtedly it is the sign of 21st century flops

    Firstly, i'll take one when it comes out, so many possible uses, i would get my money's worth.

    To those that say it cannot power it because USB has low wattage, did you read the complete story plants pictures?

    "use of a combination of mobile phone radio frequencies to create the heat to cook both on the outside and within in under a minute."

    Every time you use a microwave you are bombarding your food with electromagnetic radiation not unlike the radiation that your cell phone emits and picks up on to make a call with respect to frequency. The difference is intensity. In a microwave oven the frequency and amplitude is calibrated to excite individual water molecules in a microwave oven which, in turn, heats your delicious beans. Microwave ovens focus a lot of this radiation in one small area (the amount of photoelectric energy exerted per inch is going to be MANY orders of magnitude higher ( free high school diploma ) on a surface in a microwave than, say, on the surface of your brain while you gab on your phone about how awesome/attractive you are). Cell phone radiation, like all radio frequency radiation it is non-ionizing, meaning its not going to change your DNA, i.e. your not going to get cancer from your microwave or your cell phone. Show me peer reviewed material in a reputable medical journal that proves me wrong, you won't find it.

    well, the best thing to come along since Snappy-Wrap!
    (actually, if you do the numbers you'll see it's all a mad jape...
    and April 1 has passed!)

    @Mark Agreed. If I can get my hands on some information about the Beanzawave's energy consumption, I will certainly compare.

  • Mark Bergen

    If you are looking for an energy efficient way to heat up your beans, there is no point comparing a microwave to a fridge or a washing machine. This device in not a replacement for a fridge or washing machine, so the comparison is silly. If you want to make a meaningful comparison, you need to compare it to something it could displace such as a normal microwave or a cooker.
