My wife came across the Jean Pain compost water heater recently, and I've been really intrigued by the idea. I haven't found a great compact design though, and most of the information I see online treats it more like a fun project than something that could be iterated on and refined. Would love to find somewhere to trade ideas on this and potentially replace some or all of gas water heater.
I helped build the e-commerce site for Tilmor[0] when they were starting up. They build easily repairable mechanical farming equipment for small to medium sized farms with an emphasis on organic farming. It's a really interesting niche that I think will continue to grow. I'm 6 years out from working for them and still think of their products fondly.
I love this. Great work. Huge fan of digital experimentation. It's an art form I feel isn't as popular these days. I've had an idea on the backburner for a bit now of doing a digital quarterly with contributions like this. Kind of a digital experiment punk zine. Maybe it's too niche, but I feel like it could be a good time.
