That's hilarious!

I sometimes idly wonder about harvesting the heat from various components, like we're Apollo astronauts getting every last smidgen of efficiency from our craft. In my daydream, I have wall sockets for dumping heat back into the house from, for example, the fridge, or the excess heat from the oven. I know it's not at all practical, but the idea of a hyper-efficient home is deeply appealing to me :)

That's a really fun idea. I always loved the concept of circular systems, terrariums and the like. I'd love to try and do the calculations to get oxygen-neutral with the plants in my house vs my own exhaled breath, or treat and reuse water on a local level.
