I've done a fare bit of work with composting over the years and finally have a compost bin design that is small, can capture the heat produced but doesn't require the backbreaking work of turning every two weeks.
My calculations show you could harvest £2000 of heat energy and quality compost from this system all you have to do is feed it and empty twice a week.
Use the heat for you home/office, greenhouse or even a swimming pool all for free, and you get 170 bags of compost for the garden.
