Here's a cool composting project that my wife would never let me try in a million years.
What's that honey? You ran out of hot water in the shower? Okay, let me go throw some coffee grinds on the compost pile and that'll get it cooking again.
Ideas like this are still way too raw to actually benefit anyone. But hopefully some enterprising inventor will stumble across this and come up with a way to build a compost bin that can be used to heat water and make it look nice enough that home owners associations won't come knocking on your door once you start using it.
Just think about all of the problems that a home composting system that could also heat hot water would solve.
- Less waste - Most of your garbage would be composted
- Free compost - No more buying fertilizer and the garden will look great
- Free hot water
- Free heat
