Wow, I really thought desalination would be something like factor 10 more energy expensive.
Regarding your greenhouse: Does it sit flat on the earth? I'm thinking about lowering the greenhouse at my parents house somewhat into the earth, I think 2 feet would already help with keeping it warmer...
- Mistletoe 4y agoNo it just sits on the ground. I went down a whole rabbit hole recently about how to keep a greenhouse warm in winter. Being below ground would probably help somewhat. A lot of people do something like this- https://ceresgs.com/environmental-controls/gaht/ https://ceresgs.com/environmental-controls/gaht/ I did the math and used a kill a watt to monitor the usage and just doing a little space heater hooked to an Inkbird temperature controller was plenty economical for me. I have cheap electricity where I live though. About 30 cents a night when it is freezing outside. So absolutely worst case scenario would be $9 a month which I can handle for how much joy it gives me to be able to grow plants in the winter.
- martin_a 4y agoWow, that's sure another level of tech with the ground heater. Not sure if you can DIY that thing... Sounds great with your energy prices. At that rates, I'd go for electric heating, too. :-D
