> Aboard the ISS, the issues with baking in particular are a question of power. The entire station runs on about 75 to 90 kilowatts per hour of electrical bandwidth. Silicon Valley Power estimates that a conventional electric oven uses 2.3 kilowatts, which is about 3 percent of what’s available on the ISS. Heating and cooling are both just extremely energy-expensive. > So a conventional electric oven will probably never find a place on a spacecraft. So the ISS has a usage range 75 to 90kw, and the oven needs 2.3...and that makes it a no-go? The ISS crew is only 7; it's not like you'd need multiple ovens to feed all of 'em. And for most foods, you can time your cooking to have direct sun on the solar arrays (vs. using battery) for >90% of the energy that the oven will need.
