That fitting is installed between the hot and cold supply lines at a single location/fixture in the house, usually the farthest away from the heater. Then, a compatible tankless heater can use a pump to push hot water out while pulling the cold water back in through the cold supply line - so no extra recirculating pipe has to be installed. You trigger the recirculation with a switch at the fixture, on a schedule, or with an app/smart home device.

The first one was done in Jan 2022. The patient, David Bennet, survived for 2 months.

And you need to buy 2 if you don’t want to rebound!

By my napkin math, from 32 billion km away, a 2deg error means Voyager 2 is pointing to a spot 1.12 billion km away from Earth (at right angles). That’s roughly the distance from Earth to Saturn 😅

Turns out there’s only about 0.25 kW of energy in a lightning bolt - which costs maybe 5-10 cents in the US - so it’s not really worth it.

Does anyone know the opposite solution? I have a MBP that always wants to be awake - particularly bc of Google Chat notifications or if my Bluetooth mouse gets bumped — is there a setting or program that will keep it asleep unless it’s opened, or even until a key is pressed?

Not right now, it’s the only item in the ASAP milestone though!
