This scares me a little. It’s a little bag with a heating element in, which claims to cook your lunch when plugged in via USB. In reality though, 60C is barely warmer than a cup of tea – certainly not enough to kill any bacteria. Don’t rely on it to grill a steak beyond “rare”.
On the other hand, if all you’re doing is heating up your cous-cous, then my objection isn’t so pronounced. Who knows? Maybe in the hands of Heston Blumenthal it could be a force for good. Now there’s a program I’d like to see – Heston Blumenthal’s USB Lunchbox.
