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.

Dang it, you’re technically correct. The best kind of correct.

I just looked it up on Fandom and they concur, although he possibly has a doctorate in art history.

Zoidberg has an MD, should at least be right of center.

And I don’t think Doc Oc or Robitnik have medical degrees. PhD, but not medical.

Sorry, looking for DX only

They’re affiliated with two universities. Their card can only list one affiliation. When the organizer asked which university to list, they said “probably University X”. Most people would have simply put “University X”, but since the person said “probably” the organizer decided to be literal and also put “probably”.
