But beyond that they hide a very cool, very safe little feature for households with small children.

The childproofing is really pretty simple: When you're done cooking, or when the stove top is not in use, simply remove the magnetic discs from their holders and the unit is effectively impossible to turn on. Presto change-o, no toddlers running around your kitchen screaming to child services that they have third degree burns on their hands and arms.

And as the picture implies this is an induction unit that's the perfect fit for your eclectic collection of cut in half skillets and other cookware. [Press Release via Born RIch]

<![CDATA[Cooking with Magnets: An Intro to Induction]]> Induction stoves may be making their way into restaurant kitchens, but for home cooks they're still a mystery. Fortunately, Wired product editor (and food geek) Mark McClusky volunteered to enlighten us:

It took me nearly an entire evening in the the kitchen at Alinea before I realized what was weird about it. Sure, there's the stunning intensity of the chefs as they prepare Grant Achatz' intricate dishes, and the nearly-operating room level of cleanliness. But that's not what struck me one night at the end of service. What struck me is that I didn't know where the stove was.

You see, in most restaurant kitchens—like most home kitchens—the stove is the focal point of the room, the place that all the action revolves around. If you're running the sauté station in most big restaurants, you're the man, the line cook who's banging out the most food in the hottest, most extreme environment. You're the alpha cook.

Not so at Alinea. Of course there's a stove, but it's much smaller than you'd expect for a kitchen that puts out a couple of thousand plates a night, just four burners and a flat top. Instead, the chefs at Alinea do the vast majority of their cooking using induction burners, portable ones from CookTek.

Induction is just plain cool. Instead of using a flame like gas, or radiant heat like standard electric burners, induction burners use a magnetic field. The field creates heat through the property outlined in Joule's first law—you do remember your thermodynamics, right?—in which current passing through conductive material generates heat.

So what? Well, a couple of things. First, induction is super-efficient. Induction burners convert about 85% of the energy you pour into them into heat, compared to about 70% for electric burners and 40% for gas. That means you'll spend less to cook on induction.

And since the burner itself doesn't create heat, it stays cool to the touch—take the pan off, and you can put your palm on it. That also means that they don't throw off ambient heat like gas or electric, so the kitchen stays much cooler.

Then, there's the responsiveness of induction. Like gas, when you turn it off, there's no residual heat from the burner, just the pan. Plus, there's the flexibility of portable burners like Alinea uses. Frying something smelly? Got an outdoor power outlet? Set up a portable burner, and you can keep the stink out of your house. Want to keep soup warm at a party? Throw a burner on the buffet, and you're good to go.

The one thing to keep in mind is that your pans do have to be magnetic. That might be a pain in the ass, especially if you're hip deep in anodized aluminum pots. But the good news is that some of the cheapest (and most fun to use) cookware around—cast iron—works amazingly on induction burners, as will all your fancy pots as long as they've got some stainless steel kicking around in them. If in doubt, grab a magnet from your fridge door to check.

As far as specific models to check out, Circulon makes a nice burner, and Spanish appliance giant Fagor has one. For the best combo of power and price, check out the Max Burton 6000, which puts out 1800 watts for just $125 retail.

That's how to cook like they do at the best restaurant in America. Or, really, it's how to cook with the same methods. The talent is up to you.

<![CDATA[New Induction Cooktops from GE Are the Highest Wattage Ever]]> Our cooking experience barely goes beyond "Fire. Bad. Keep. Away," but these GE Monogram and Profile induction cooktops have the highest wattage element from an induction cooktop ever. The 3700-watt cookers use magnetic fields to heat up your food, as opposed to gas or electric cookers. Induction cooking's been around for a while, but as evidenced by the small shot of a bunch of ice cubes sitting on the same plate as a tray of boiling water, this technology is fancy. Just cause they're as close to Star Trek as you're going to come in the kitchen, save for the microwave or something. [GE]

<![CDATA[Wireless Gadget Charging Makes World Debut July 9]]> Remember those WildCharge wireless chargers we played with back at CES? They're almost here. You'll be able to get one July 9.

Thoughts of hand cancer aside, the way these WildChargers work would require a couple of physics classes to completely understand. The layman's explanation is that it uses inductive charging—the type you see in Sonicare toothbrushes—that will charge your gadget just by placing it on a sheet.

Some more familiar companies other than WildCharge such as Apple, Motorola, and NTT DoCoMo all have their own wireless charging devices in development as well.

What's the point of all this wireless charging? Mostly convenience in not having to have multiple chargers and charging adapters, which may win out over our current favorite charging system, the Chargepod.

<![CDATA[Wireless Docking for iPhone, iPod Coming?]]> In yesterday's patent application Apple filed for its multi-orientation docking station for the iPhone, there was even more tantalizing information: Apple may be preparing wireless docking for its iPhones, iPods and other devices. The technique will use voodoo called induction, and involves hiding coils underneath the surface of a device and its cradle, with the ability to wirelessly transfer data and power.

Here's the evidence:


From the patent application:

"The inductive coils are typically hidden from view behind the housings of each device and therefore they are more aesthetically pleasing than electrical contacts, which need to be exposed in order to operate effectively... Furthermore, inductively based systems are more robust than electrical contacts. For example, there are no contacts to wear out and/or oxidize."
We saw similar technology at CES demonstrated by Fulton Innovation with eCoupled, using inductive coupling to transfer power across thin air. Even though Apple mentioned a similar technique in its patent application, this part of the equation already exists. Expect to see this wireless juju showing up on Apple products and many others in the near future.
