With over 200 million metric ton being harvested annually, rice is one of the staple foods for most of the world. That works out to be somewhere in the neighborhood of 7,257,477,920,000 grains of rice, in case you were wondering. And in order to cook all of that rice, you’d need something like 170 billion rice cookers. Or would you?

Japanese developers have created self heating boxed rice, which (with the simple addition of cold water) steams itself. The rice is precooked at 4,000 atmospheres of pressure, which preserves it. An exothermic agent inside the box reacts with the added water to heat up the rice in about 15 minutes. It’s designed for disaster areas, but according to the news report, the product is currently on the market, and side dishes are in the works. “Hotto! Raisu” is about $2.75 per box, which includes pickled ume plums. Now if they can figure out how to prepare more items by adding water, I can finally learn how to cook.
