Self-Heating Can

nickprecision writes "Ontro has been working for a while, and they are about ready to get to the public market. Quite a nifty little self-heating can... imagine the uses. Read up so you know about it when your friends pull one out on the ski hill."

  1. Already In Europe by Dave500 · · Score: 5, Informative

    Just a sidenote - in Europe (well - London) Nestle already sell similar cans of self heating coffee. Works quite well - shame about the taste of whats in the can though. I can't remember the reactants - but the oxidser is diluted hyrogen preoxide.

    Quite neat really: a cup of coffee (two versions: white, and white+sugar), with a little capsule on the bottom. Press the button (filled with red gel), wait a couple of minutes, then drink!

    It looked like a nice idea, but I didn't try it - mainly because of the price: £1.30 IIRC, which is about $2. It seems a bit much IMHO for a normal cup of takeaway coffee, even if it does have a neat self-heating function! Good for camping trips, perhaps, but not in the roadside service station where they were selling it: you can buy normal fresh coffee for the same price and get a seat and newspaper to go with it...

    Clearly neither you, nor the dumb-assed moderaters who modded you up, nor the other dumb-asses who posted the exact same thing as you, nor the dumb-asses who modded them up, bothered to follow the link.

    If you had, you would have seen:

    "While on a trip overseas in the early 1990s, Ontro's founders, Jim Scudder and Jim Berntsen, came upon an interesting product ... a beverage container that would heat its contents without the benefit of external energy sources (microwave, heating element, etc.). They soon found similar products in other parts of the world, but all had two very significant problems."

    Followed by information about what makes their product different.


    This is what is known as promoting your product. What do you think they would say? Our product is exactly the same as the others? It's more expensive?

    There is nothing revolutionary about this product. It works in pretty much the same way as the products available in Europe and other places.

    Don't be so critical of other posters and moderators. People might think you're a dumbass yourself.

    The huge flaw in their design is that it contains Calcium Oxide. AKA Lime. AKA Quicklime. AKA a substance used in manufacturing steel and paper, in glassmaking, in waste treatment, in insecticides, and as an industrial alkali

    Oh no! It's a chemical with various uses! It must be bad for you!

    You forgot to mention that it's a substance that has been integral to American cuisine for just about ever.

    Corn is steeped in lime, AKA quicklime, AKA Calcium Oxide, to form hominy (if you're in the South,) or posole (if you're in the Southwest.) It It is dried and ground to make masa, which is used to make corn tortillas (ordinary cornmeal won't work), and tamales. Treatment of corn with lime or other alkali unlocks essential nutrients such as niacin which our bodies cannot obtain from untreated corn.

    Sheesh. Next I'll be hearing people panic about the pollution of the oceans with Sodium Chloride and Dihydrogen Monoxide.
