The minds at Black & Decker have created a thermal leak detector that can help you save a lot of money (and energy!) during the winter months. The gadget works by using an infrared thermometer that detects variations in temperature, even if there’s only a difference of one degree.

The thermal leak detector projects a spotlight onto the area that you’re inspecting, shining a blue light wherever it detects a leak. People can use this information to seal up any air leaks around pipes, walls, ducts windows or doors, leading to less energy consumption. Plus, drafts are annoying.

As somebody who has recently sealed up every window in her house with those plastic sheets that you blow dry tight, I’m pissed this isn’t on the market already. Even worse, Black and Decker are teasing us…it won’t be available until Spring!

When it does come out, it’ll only cost around $40. That’s not bad, considering the amount of cash you can save on your heating bill each month. As more and more companies come out with neat innovations like these, I have a feeling more and more people are going to be going green (if for no other reason than to save money).
