Some food contrasts go well when eaten together. For instance, some people like Sweet-n-Sour ribs. Some people like a nice cold drink to go with their hot meal.
The Hot-n-Cold Plate has one half for keeping hot foods hot, while the other half keeps the cold foods cold. A Peltier Effect electric heat
pump maintains a temperature gradient which keeps the hot half of the plate hot, and the cold half of the plate cold. It's powered by a rechargeable battery and can be plugged in to a wall outlet.
You can keep your hot hamburger and bun on the hot half of the plate, while keeping your cold crisp slices of pickle and tomato on the cold half. Slap it all together just before biting into it, and enjoy the complementary contrasts in your mouth.

The basic concept appears to be a pretty old Idea [Vernon, Jan 08 2014]

Be aware that battery life will be pretty low -
Peltiers are hungry. |
|
| |
The plate should actually be two separate, removable units - probably
in stainless steel - rather like a sandwich toaster. Then they can be
removed for washing, and new ones just dropped in (held by magnets
to maintain good contact ?) |
|
| |
Low partition between the halves to prevent inadvertant mixing. |
|
| |
Heating peltier under one side, cooling on the other, linked by a
heatpipe or just a big block of Aluminium. |
|
| |
Small insulated assembly area off to one side ? |
|
| |
Yeah, I was going to mention some more stuff like that, including also color-coding the 2 halves to make it obvious which is the hot half and which is the cold half. |

Not an issue, you can claim some of the electricity
back by incorporating a second Peltier. This will use
the temperature difference generated by the first
Peltier to generate current. |
|
| |
Just a matter of joined up thinking. |
|
| |
if IR lamps are anything like Peltier elements, simply
reverse the polarity on the lamp. |
|
| |
Actually I like this idea a lot. It'd be pretty simple to
incorporate a microcontroller with
thermistor/thermocouple sensors. You plop your
hot/cold dish on the plate. Initially, the plate does
nothing until the temp readings stabilize... they will
be either hotter or colder than RT. Then, the micro
controller just maintains that temp. |
|
| |
This would be very useful for people who find
themselves temporarily without good waiting staff. |

Oh no, not again … we forgot that your Great-
Aunt Malevolentia was staying over New
Year. |
|
| |
Presumably she appreciated her Christmas
gift from Sturton, which does not surprise us;
however, it was clear from the beginning that
any situation involving your Great-Aunt and
Sturton's well-intentioned, inadvisable but
sadly all-too-successful attempt to combine
an industrial ceramic Assegai blade with a 2-
stroke powered grass trimmer was going to
end badly for someone. |
|
| |
How many did you lose this time ? Not all of
them, shirley ? |
|
| |
She's not actually an "aunt". It's hard to say what
she is, exactly, but "adopted vagrant" comes
closest. We were very pleased when, this
Christmas, she stopped biting the dogs. |
|
| |
Incidentally, Sturton sends his best wishes and
says that he will return your "items" as soon as he
can work out how to get them through customs. |
|
| |
The intercalary also says to say "hi". Hi. |

Vernon - this Hot-n-Cold plate isn't just limited to hamburgers. I just used the hamburger as an example. Wow, was that Jason Alexander's real hair? |

read up on your thermodynamics, you can not gain
more electricity than the original peltier used, and
since you are suddently using head to power a peltier
the plate wont get warm... |

It's OK, any electrical energy deficit can be made
up with power from a small wind turbine, which
will work anywhere on account of it being
powered by an electric fan. The fan is solar
powered, which would normally present
difficulties at night, however, a bank of floodlights
should solve that problem. |

This is a Hot-N-Cold Plate, which means it's just like a regular Hot Plate, but it also does Cold. The purpose of this is so that you can have both hot and cold stuff served together. |
