Okay, it's a Kickstarter, so it may never happen, but:
https://www.kickstarter.com/projects/1103525718/morphcooker-the-all-in-one-electric-camp-stoveCute versatile design, but the real question is the power source.
I'm guessing a power tool size battery, maybe 100Watt-hours or so?Ah:
The Morphcooker is using high-end Lithium Ion batteries. It has 16 cells, where each is 2600 mAH at 3.7 volts, with 2 parallel groups of 8 in series, for a total of 29.6 volts at 5200 mAH.
Assuming 45g per 18650 cell, that's consistent with their quoted battery unit weight of 750g. I suppose that's no worse than carrying a bottle of liquid hydrocarbons around, except one works for a meal and the other lasts a week or two. Boils water at a speed that makes a Trangia look quick.
But ...if you can get access to it, electricity's a fairly universal fuel. You're unlikely to start any fires with it. You could safely use it indoors. You can bake with it. With sufficiently reliable solar charging (I'm picturing boats and velomobiles in warmer climates) you could be completely off-grid.
It's a bit niche, but I'm sure someone will find it useful. Interesting that it's become practical, and an idea worth revisiting as the cost and energy density of batteries improves.
