For anyone who's always eating on the go, you now have another option to manage hot meals while commuting without requiring the use of a microwave or toaster oven.

Currently on Kickstarter, the HeatWave Go is a self-heating lunch box that uses infrared technology to warm up meals. It reportedly doesn't affect nutritional value, but provides enough heat to quash bacterial growth while ensuring food remains tasty and moist.

If you’ve ever been to an infrared sauna, you may have noticed that the heat radiants more evenly over your body compared to the heated rocks that leave your extremities feeling a bit cooler and your torso hotter due to the heat waves reaching a range limit.

Warming up meals in a toaster oven likewise results in uneven heating, with the top portion getting dried or burnt and the middle part ending up lukewarm if the element is located on the top – the reverse is true if the element is on the bottom.

With a microwave oven, emitted microwave energy is changed to heat energy that is absorbed by the water molecules in food, causing them to vibrate. This cooks the food only, leaving the container unaffected. High-water-content foods like vegetables are cooked quickly and efficiently in a microwave.

However, this also results in the bottom portion being scalding hot if a meal is sauce-based like pastas, and the top portion being undercooked with random cold spots. Microwaves also cannot heat frozen microwavable meals internally with high enough temperatures, or long enough to fully kill bacteria such as salmonella or listeria due to inconsistent heating.

The HeatWave Go features a stainless steel reflective insulated cover and an infrared heat lamp tube in its top section, located above a food-grade stainless steel lunch box. Utilizing this combination, it's able to achieve a uniform temperature with no direct contact with the food, thus resulting in what the creator claims is “100% heating without dead angles.”

Infrared heating works by transferring the heat directly to the food which warms up and re-radiates the heat evenly throughout. Warming a meal completely takes about 15 minutes, with the temperature reaching 55 ºC (131 ºF) to ensure adequate heating that does not damage nutrients and prevents bacterial contamination.

Remote monitoring of the process allows for unsupervised usage, and is made possible via an app that's programmed to display real-time temperatures and to send completion alerts when the meal is fully warmed.

You can get your very own HeatWave Go lunch box for a pledge of US$99 – the planned retail price is $159. If all goes well in funding and production, it should start shipping mid-2026.

Should of made it battery powered. People at home have microwaves. People at the office have microwaves. But people who work a trade job, often don't have a microwave, or sometimes a power source. The market for this is someone who's mobile, which means portable, which means CORDLESS.

I totally agree with @Smokey_Bear although many will prefer non-microwaved food. Just off the top of my head though, when researching far-infra-red home heating, I remember the ‘science’ being described as “only heats the surface of objects and you’. So this product will totally rely on heat absorption from the surface of the food. That won’t work with drier foods like pasta or anything else with spaces in between the food. I’m guessing this is really only for wet foods. In fact, I just asked GPT to verify: What far-infrared actually does
Far-infrared = long-wavelength infrared (roughly 8–15 µm)
It: • Is strongly absorbed by water • Is absorbed in the first 0.1–0.3 mm of food • Turns into surface heat only
So when FIR hits food:
The outer skin heats up, then the heat must slowly conduct inward.
That’s the slowest possible way to heat food.

I don't see how heating the top surface of the food is superior to heating the bottom and sides of the food via direct conduction; both rely on conduction within the food. If your meal consists of fairly dry food (noodles, rice, etc) with some moist chunks lurking inside, neither method will work well, drying the outer material (and making it less conductive) before the moist chunks heat up enough. That meal example would be best heated via microwaves. No one ideal method for all possible meals. I expect the marketing for this gadget carefully chose meals that would heat up well by this method.
How about a contest: this gadget vs other ones, with test meals selected by someone other than the ones selling the gadgets.

All heat is infrared radiation.

Article makes no sense. Had plenty of microwave ready meals cooked from frozen and I lived but I certainly wouldn't use this... the recommended core cooking temperature to kill Salmonella is 75C... the above says this does 55C...
