The energy efficiency of the appliance will only be a small dent in the energy consumption of cooking the rice. Most methods rely on boiling the water. Heating water up doesn't take very much energy - about 4 kJ/kg/K. This means that heating 1 liter of water from 20 C to 100 C takes about 320,000 Joules (1 kWh = 3,600,000 Joules).

Once water is heated up to 100 C, the next step is boiling where you phase change from liquid to vapor. The specific enthalpy of vaporization for water at atmospheric pressure is about 2000 kJ/kg, so the one Liter of water would take 2,000,000 Joules to completely vaporize. You could weigh your pot before and after cooking to see how much water you vaporized.

Let's assume you have 1 kg (about 1 liter) of water and 1/10 of it vaporizes. The minimum energy for this is about 500,000 Joules assuming 100% efficiency. Divide by efficiency, so if the appliance is 90% efficient it would be around 550,000 Joules, while 80% would be about 625,000 Joules.

So, to answer your question, the most energy efficient method will minimize vaporization. Soaking the raw rice for a few hours will help reduce boiling time. Then use a standard issue rice cooker, which should stop the boiling process as soon as the rice is finished.

Maybe we'll find Black Mesa

Maybe Microsoft will be giving a discount on the licenses to the affected people

You can't even imagine these kinds of numbers

With or without Ammonium chloride?

It might be fun to see a good KSP 2. I never got the official KSP 2 because of the reviews, but KSP original is still awesome.

Time to start designing a self-sustaining perpetual train

I take lungs now, gills come next week.

From my understanding, they won't start the procedure until the person is declared dead and the heart stops. It may seem morbid that they're waiting for someone to die, but they're not going to start hacking someone who still has a heartbeat much less is awake. They didn't "stop" the procedure because he was showing signs of life, they didn't start the procedure because he wasn't showing signs of death.

Pikachu dong? NSFW

About once a year, we get a Netflix subscription for about two months. Catch up on everything we want to watch, then cancel it.

After 6 months, Netflix forgets about you. Does that mean we count as a new subscriber every year? How many people like us are inflating their new subscriber number?
