Non disposable barbecue

Problem: A conventional barbecue requires lots of work, lots of carrying, lots of cleaning.

Previous solution: A conventional disposable barbeque is a misnomer. It lacks the key component of a barbecue, namely foodstuffs.

New solution: The non disposable barbecue is a single frozen unit, carefully constructed so that the top layer contains mixed frozen meats and barbecuable items, below which exists a rudimentary slow-burning grill, and below which one finds a perfectly optimised blend of fuel within a slow-burning shell. Upon ignition, the fuel cooks the foodstuffs to perfection, which are at this point consumed. The fire continues to consume the remainder of the barbecue. Nothing remains but a little hot ash.

Drawbacks: 1) You don't get to choose your foodstuffs, as they are preselected by unit purchased. 2) There's no chance of a traditional over-cooked or under- cooked item.

       The grill plate will be a technical challenge, but [+] anyway.   

       A material that's heat-resistant, but water soluble - maybe clay-based - would probably be best.

       //The grill plate will be a technical challenge,//   

       The existing disposable - er... things? already solve this. They use a fine steel mesh. With heat moisture and oxygen, they essentially rust into nothingness on the scale of weeks.

       What about magnesium for the grill? Protect it from direct flame during the "cooking" phase so it is only transmitting (relatively low) heat to the food, but allow it to ignite right at the end (remove food quickly before this happens...).

       // remove food quickly //   

       Get the combination of alkali metals right and you've actually created a "pop-up" barbecue ...

       Do they license the technology from Fiat ?

       //Do they license the technology from Fiat?//   

       I assume it was all off-patent long ago. Fiat, Lancia, BL, MG & even Merc were doing a fine job back in the 70's

       Yes, but that's a bit like all the "me too" Dyson clones; it's Fiat that originally perfected the idea.

       There is a problem with the name. As described, it is nonetheless possible to dispose of this item before it is unwrapped and used.

       [pocmloc] has identified the flaw with this, and I am afraid it may be insurmountable
vincevincevince, Oct 01 2020
  

       // insurmountable //   

       Well, maybe not, could you not use brackets, or a little plinth or something ? Or even double-sided tape ?

       //[poc], please make your way to the stage to receive your complementary six-pack of Rentisham's Special Old Peculier ... "//

sp. 'complimentary', unless [poc] already has a six-pack of RSOP...
hippo, Oct 02 2020
  

       I always have at least one six-pack.   

       Now back to the problem. If the item was made big enough it would not fit into any kind of bin and thus would not be disposable? There must be a better way to satisfy the specifications.

       Maybe the answer is in the packaging: The non-disposable barbecue should be wrapped in packaging which says "Disposable barbecue" on it. Taking off this packaging reveals the product itself, which has "Non-disposable barbecue" printed on it. So, if if you dispose of the product before use, you need not be troubled that you are disposing of a non-disposable item, because it says 'Disposable' on it.

To avoid the knotty paradox of some devious person removing the outer packaging to reveal the 'Non-disposable' label and THEN disposing of it, the product should be designed such that removing the outer packaging initiates the chemical reaction which will ultimately cause the barbecue to ignite, cook your food and self-immolate.
hippo, Oct 02 2020
  

       Genius, [hippo]. In fact all you need is a big sticker marked "peel to ignite" covering the prefix "Non-"   

       However this makes marketing tricky since you are trying to sell the "Non-disposable barbecue" and yet all of the products on the shelf are labelled "[peel to ignite]disposable barbecue".   

       I suppose an image of the product just after peeling could be shown on the packaging, so that the "Non-" was visible in the image but not on the item itself?
pocmloc, Oct 02 2020
  

       Surely just marketing it as "Latently non-disposable barbecue" will make everything clear to the consumer?
hippo, Oct 02 2020
  

       Or stab to ignite. The cooking exposes the meal.
wjt, Oct 03 2020
  

       //it is nonetheless possible to dispose of this item//   

       Surely this problem is soluble with robotics and cyber-stalking. Once you've bought and discarded it, it will creep out of the bin and follow you home.

       And feeling aggrieved, house sized barbecue.
