Rapid Cooling A Hot, Parked Car

The sun is blazing out there but you couldn’t park your car under the shade. Blasting A/C isn’t a good option since you first have to endure the hot air. Wouldn’t it be great if you can cool down the car before you get inside and give your poor A/C a little help?

A friend found a clip from a Japanese show with this tip from an air dynamic professor.

What do you do?

  1. Roll the driver side window all the way down
  2. Close all other windows
  3. Open and close the front passenger door at least 5 times (you don’t slam the door shut, just close and open normally)

In the video the car went from 41.6 C (106.88 F) to 33.5 C (92.3 F) , with the outside temperature at 30.5 C (86.9 F).

How does it work?

It works not by pushing hot air out the driver’s window but by sucking cool air in with the passenger door.

Notes: (from the video)

  • Be careful not to jam your fingers under the door lever
  • Make sure there are enough space for you to open your door fully
  • Be sure other cars and people are in a safe distance

A friend tried it and said it works well. Let me know if it works for you, too!

Best Green Carpet Spot Cleaner

UPDATE: Folex has replace this as my #1 carpet spot cleaner (12/16/2015)

Reuse is a good idea. Using something until they can no longer function is even a better idea. That’s why we have the need to spot clean our carpet.

After trying all kinds of big name carpet spot cleaner and not getting the results I wanted, I decided I should at least go green.

Naturally It's Clean Carpet Spot CleanerAs a test, I bought a bottle of Naturally It’s Clean Carpet Cleaner, expecting it to only work as well as the other cleaners I’ve tried. I soaked a pretty dirty spot waited 5 minutes, dried it with an old t-shirt. Wow, that spot is now clean!

I was so impressed, I went to Naturally It’s Clean web site and found out that they have products for floor, kitchen, laundry, toilet, and more. They are all non-toxic, safe, and made in USA. If you want to find it locally, use their “Where to Buy” tool.

I’m trying their Kitchen cleaner next.
