Necessity is the second cousin twice removed of stupid inventions

My sister-in-law keeps forgetting to plug in her crockpot, making for disappointing meals. One of her cousins suggested that she needs to find a slowcooker with an alternate energy source. I’m surprised that no one has thought of this solution before.

Car battery powered crockpot
I’m now working on a version powered by AAA batteries. I figure it will take only about 600 or so to cook something, so stay tuned!
