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 either a standard issue rice cooker, which should stop the boiling process as soon as the rice is finished.

Starting to change from some to most to all.

How long do I need to ponder the orb until I develop this kind of power?

Differential calculus? That looks more like algebra. Their speed is constant.

Earth - any water repellant fabric, probably synthetic

Venus - I'd go with Teflon and extend it to the ground

Titan - SCBA

Neptune and HD 189733b - something hard and durable but lightweight. I'd go with titanium. Chainmaille extending to the ground.

OGLE-TR-56b - tungsten, with a mobile support apparatus.

They'll pass legislation to give the authority to the governor if they get a republican back in. They just want to make sure it's not the wrong side spending the money.

Feels like something Pratchett's DEATH would do, just to piss off the auditors

Jackfruit recipes (beehaw.org)

So, I bought several bags of frozen jackfruit thinking I would use the slow cooker to make some BBQ. Then I realized that it's ripe jackfruit, not young jackfruit. What can I do with it that's not a smoothie?

Off by a couple orders of magnitude there, Alex. Setting for $55M per year for the next 30 years would work.

This was predicted on the post about Beeper
