This is perhaps the most simultaneously beautiful and asinine thing I have ever seen on the Internet. A gas grill “attachment” that heats an 8000-gallon swimming pool 20 degrees in 48 hours using “only” 3.5 tanks of propane. Um, dude, that’s still $50! Not to mention what has to be several hundred bucks worth of copper pipe and untold hours with a torch (and, oh no, more propane!). By contrast I’m pretty sure my permanently-attached and dedicated pool heater could boil off my entire 10,000-gallon pool in that span of time and for less money.
