HEAT RETENTIVE PLATES

Hello,
I have invented a new type of ceramic "heat retentive plate" that you
preheat in a microwave oven for just one minute, it stays HOT for 1/2
HOUR and the rim remains cool for easy handling.
Please see:
http://www.heatstoragedish.com
I will answer any questions and teach anyone interested how to make
them.
The plates are great for steaks, but I use them daily at home for
everything.
Truly yours!
Juan

P.S... By the way, I believe this is the first "functional" change to a
ceramic plate since the discovery of ceramics in China and Japan in
10,000 BC

Excellent concept!

I for one would be very interested in your method, even if I never
made a single plate. I'm guessing maybe some sort of silicon
carbide microwave susceptor (judging from the cutaway view
shown on your site). But I'm impressed that you can make this
work without undue thermal stress on the rest of the plate.
Is the susceptor insert perhaps able to move relative to the
more-conventional ceramic surrounding plate? From the drawing
that looks possible, but I'm mystified how to do that without
having it rattle. Good work!

And thanks for the offer to share the secret.

Best regards,

bob, sounds like a scam to buy his plate. much like a perpetual motion
machine. if a plate retained heat so well, it wouldn't do much good in
keeping steaks warm either.

take a brick out of a raku kiln for 1 hour & you'll see a good deal of
heat "retained" lost to understand the scale of his claim. it'll reach
room temp in an hour, maybe 1/2 hour.

THAT's from 1800F... AND it'll keep steaks warm...

now, pull anything from say 400F out & leave it sit. ~ room temp
pretty quick. (even zapped in a micro)

the claim doesn't make sense in the heattransfer world which is why no
such device has been discovered in 10,000 years... unless it's an
exceptional insulator which doesn't keep steaks warm.

see ya

I don't see him claiming anything that violates any laws of physics.
A plate is a big mass, relative to the food you put on it. If you
put food on a cold plate, the food will cool down faster than if
you put it on a warm plate, because the food is transferring heat
to the plate due to the temperature difference. As I understand
his design, it just reverses the situation so the plate is as hot as
or hotter than the food. As a bonus, the plate apparently has
embedded in it a big slug of some substance that heats up via
microwaves. That extra mass will further extend the temperature
decay time. Nothing tricky about that, it's just like heating
a heavy plate in a conventional oven before you serve the food.
His invention is all about heating it quickly in the microwave,
without cracking the plate.

Yes, but the mass of the "energy reservoir" will - by definition -
require a large amount of energy to heat it up sufficiently.

Whether it is possible for this to be practical will depend on whether a
standard microwave oven could lead to the absorption of sufficient
energy in 1 minute to provide a sufficient reservoir of energy to
maintain the plate's temperature for eg 30 minutes.

Also it needs to be borne in mind that the "standard" part of the plate
will not be heated by the microwave energy and therefore the internal
reservoir also needs to provide sufficient energy to bring the rest of
the plate up to its "hot" condition.

I'm far from convinced !

Hi Bob,
It does not rattle because the separation between the pointed bosses
and the heater is only about 1 millimeter, the susceptor is simply iron
particles and red earthenware. I can say it because the patent will be
published in a couple months, it won't be a secret anymore. the market
is huge.

Hi Steve, it is not a scam, the trick is releasing the heat at a
controlled rate according to the stefan-Boltzmann law., it is not based
on insulation but containing the radiation in a tight cavity. If the
surrounding temperature of the radiating body is high enough, it will
contain the radiation.go to this site, look for radiation, then
stefan-boltzmann and look at the formula.. if you have more questions
(doubts) please let me know.

steve,
I forgot, you can't buy them, I have the only working prototypes.
By the way, If you prehea t them for 1:15 minutes, they remain HOT FOR
45 MINUTES.(140deg. F after that time). I can teach you to make them.or
rather post so that everybody learns. just let me know.

Thank you, they really work, I use them every day, I also have coffe
mugs, those were a piece of cake after solving the problem of thermal
shock in the plates.

Bob,
The trick is not only the mass of the heater or susceptor inside the
plate, but
how efficient it is to capture microwave energy very fast and how it
is released at a controlled rate. I capture about 1200 Watts minutes of
energy and release it at the rate of about 37.5 watts per minute, that
is like having a light bulb of 37.5 Watts inside your plate.
Could you post this to all your groups?
I'm new to this. I will really appreciate it.
Juan
