You probably know that the radiator in your car cools your car’s engine. It does this by allowing outside air to flow through the radiator core thus cooling the fluid circulating inside. The problem is that cars aren’t always moving so years ago engineers designed special fans to physically pull outside air through the radiator. This is an especially important process when a car is running yet standing still -picture getting stuck in a traffic jam.
Air conditioning (AC) systems are pretty simple. You turn them on, cold air blows out and soon the inside of your hot car is nice and comfortable. It’s almost magic but ever wonder how this all works? Exactly how do you make “cold air” anyway?
It doesn’t happen often in newer cars but all cars can develop “vacuum leaks.” It’s a situation where a hose or engine gasket has failed and outside air gets pulled into the engine while its running. This can create all sorts of problems, some of them being significant but most just leading to poor engine performance. In general, fixing a vacuum leak is something that you leave to your mechanic but they are worth learning about. You never know when a mechanic is going to say to you, “you’ve got a vacuum leak that I have to find.”
Going green isn’t always easy, particularly for some folks at the lower end of the economic spectrum. This is a challenge all green activists must confront.
As civilisation develops, concerns about the environment are at an all-time high. However, technology enables innovation like never before, and a lot of exciting new green technology is on the anvil. Here are four major new green technologies that promise to make the world a better place.
