odd question for inventors
This is probably going to sound like an odd question, but is there a solar powered device that I could put in a small tub of water to prevent it from freezing. It doesn't get all that cold here normally. 'Though it was cold enough last night for my rabbit's water system to freeze. It's about a gallon of water in a bucket with tubes going to each cage and a nipple on the end that they can lick for water. I could probably insulate the tubes better but that won't help if it's got cold water flowing into it. I've seen water heating systems for livestock in the feed shop. They are a heating element that you emerge in the water. But they all seem to need an electrical source and I've haven't seen any that are thermostat controlled. It would be silly to keep it on when the water is warm. Also, there's no electricity down to where the rabbits live.
so, tell me, is there a solar powered, temperature controlled, water heating device available for an affordable price or has this yet to be invented? If it does exist, how many batteries, at what strength, would it require to make the heating work?
I'm off to carting hot water from the house to the rabbit's home for the rest of the morning if anyone needs to get in touch.
