That has actually been picking up steam on social media if I remember.
The idea is that you have a bar of soap + a harder bristled brush (IKEA sells cheap ones but there are probably BIFL ones) and then you just froth up some soap on the brush with one hand and then use it to scrub the dishes.
I think those people used special soap formulations though that weren’t just a dove bar


Spinning up and down hard drives repeatedly drastically reduces their lifespan though. Once a day or so, fine, but if you set a 30 minute idle time or something and it spins them down a dozen times per day, you are putting acceleration forces on the drive many more times than intended.
If you have to buy a new HDD twice as often because you spin it down, any financial or environmental savings is instantly negated and in the end it is much, much worse in both respects.
