Water from A/C overflow

Sounds like a good idea, Kiwoka. The water has been condensed from the air that passes over the a/c evaporator and should be very pure. The amount you get will depend on the humidity of the outside air.

This sounds like a great idea. You may have found an idea for a niche market! I might investigate doing the same on my Jackaroo, as it produces heaps of water in Sydney. Just be aware when doing this that you don't get water backing up into the condenser. You need to ensure that if your tank gets full, any extra water being produced still has a path to be expelled. Another problem may be that if your car is on an angle, say a steep descent, you have to ensure that the water in your tank doesn't rush forward and up the pipe into the condenser (and maybe into the cabin). Just some thoughts. But done right, it is an absolutely great idea!

Sounds like a great idea but i'd be weary about drinking the water from an air conditioner condensor, they are known to be breeding grounds for
bacteria like Legionella. I'm no expert but the theory is that the large volumes of air that pass through the condensor help accumalate any air borne bacteria into the water collected.

The 'guys' from Qld Subaru Club have this listed as an easy mod for their members cars. In a Forester the pipe is easily pulled back from firewall and plugged into a 'Coke' bottle. If you are not sure about the water quality it could be boiled - but it is certainly a great source of water that shouldn't be overlooked.

you could use that water for washing ,showers etc and save your drinking water.
Always a good idea to have more than one supply anyway.
you should have a break of about an inch between the ac outlet pipe and the hose that goes to the storage tank, you could wrap a thin piece of foam around the break to stop dirt getting in.
