1 year agoI drink cold brew coffee for the slightly lower acidity, but I actually bought a commercial cold brew maker a couple months back. You load in as much ground coffee beans as desired, top off with water (usually a 4:1 water to coffee ratio, by volume), and leave to soak in the fridge for 12-24 hours. I usually make 2ish gallons each time, which last me a couple weeks.
Edit: It’s expensive, I know, but it: is dish washer safe, holds a tons of coffee, and is quite sturdy. There are other similar kits on Amazon but I brew for myself and a flatmate, so we go through a decent amount of coffee.
I am no electrician, but this looks to be applicable to longer sections of pipes. Instead of the heat being focused to just the areas reachable by visible light, this would allow for thawing around bends, longer distances, tighter / smaller spaces, etc.
It still uses power to generate heat, but that 60W will likely be way more efficiently applied to pipes. Bulbs will be quite lossy because heat goes through the air to reach nearby pipes (and any other nearby objects), whereas this is physical wires applied directly around said pipes.
