They already invented that and called it a fridge. But I like your maxi concept. Rapid cooling for about 30 seconds. I suggest spraying liquid nitrogen particles at a controlled rate at the said food. I can think of an infomercial
Mom: Oh dear, what will I ever do with this left over orange juice
Announcer: 'Tired of thinking over that left over orange juice ? Fear no more. Maxi-wave oven is here.'
Mom: Maxi-wave oven ? Oh but what does it do ?
Announcer: What ? You dont have one ? Maxi wave oven quickly freezes your left over juice and turns them into instant ice cream. Now watch as we turn your "liquid refreshment into energy replenishment" TM.
Mom: Wow ! How could I have been living without Maxi-oven all my life ? This is the greatest thing since sliced bread.
Announcer: But it now, only 1.99 (Conditions apply)
As for hot cubes, you can try placing your beverage at the intersection of two high velocity proton beams inside the LHC. That will give better results than red hot coal and you get free higgs boson particles in your beverage. What more could you want !
A block of carbon may work. I'm not sure in the difference between graphite and the carbon blocks I saw in school chemistry but the school ones didn't shed material like pencil graphite does (you don't want that in your drink)
The very irresponsible trick we were told was to hold a carbon block in tongs over a bunsen burner for an extended period which is required so the block heats all the way through. Once it is heated through and holding a large amount of heat energy, quench the block in water for a short period so that the outer layer is cool to the touch then hand it back to your (unsuspecting) teacher to pack away. Slowly, due to the poor conductivity of heat, the heat moves back to the outer surface making the outer surface extremely hot again and possibly burning the building down. Don't try this at home.
I guess what you're looking for is something with high specific heat (to hold lots of heat energy), higher thermal conductivity (to make the heat available), non-toxic, doesn't fall apart, and available in multiple appealing colors. Then you store the blocks in your custom heating device so they are ready to use then drop them in your fluid to be heated.
Or you can use a microwave over, stove, existing exothermal reaction heating doobie or any of several existing solutions.
Wow, the block of carbon trick sounds really interesting. It should be a CSI plot. Maybe it is.
It doesn't solve Muse's problem though. What we need is another state of matter, say solid-2, into which liquids can transition at higher heats. We'd have to work out rules for when liquids would become gas, and when solid-2. Once we work all this out, we can simply freeze-2 (we need a better verb for this) water into solid-2 cubes in the rethermorator (nice, huh?) and presto: hot cubes, which would melt-2 into water as they heated your favorite beverage! Sure, we have to alter the physical properties of the universe, but it's not like they're written in stone or anything.
While we're at it, let's make F = 0.5 ma. We'd get better gas mileage ... and shed some pounds without having to exercise!

I interpreted it as "is there a (cube shaped) solid that can added to a drink to heat it up"
I'm not sure whether this solid should also undergo a state transition (ie melt) as it is not specified.
One very dangerous solution would be (water or inert gas or non-toxic gas) ice pressurised to the point of sublimation (where the state transition is solid to gas without an intervening liquid state) and then super heated past it's sublimation temperature. Depending on the energy required for the solid to undergo the state transition, such a solid could potentially release energy to the liquid while at the same time turning into a gas that would (hopefully) have little or no effect on the beverage being heated. Keep in mind this is likely to be an explosive transition and again not recommended at home.
Superheating involves carefully heating something past its state transition without incurring the state change. It has been mentioned before but one way to see this (for a third time not suggested to try at home!)
1) get two coffee mugs and give one a thorough clean with detergent and rinse clean.
2) fill the regular cup with tap water and the cleaned cup with distilled water
3) heat both cups in a microwave (at the same time) until the regular tap water begins to boil
At this point the distilled water should also be past the boiling point of water and ready to release steam but does not due to a lack of nucleation points for the gas bubbles to form.
If you add a nucleation source at this point (like a tea bag) it will suddenly boil and spit scolding water and burning steam everywhere and has probably caused burns to many people.
