This handheld heat detector lets homeowners check for thermal leaks by translating the complicated readouts common in pro devices into three simple colored beams. Scan your house for drafty windows and doors, and a spotlight will change from green to red or blue in areas of hot or cold. Plugging up all the small leaks in your home (loose power outlets are a common culprit) can help you save as much as 20 percent on your energy bill.

But then when your house is airtight, you choke on your own pollutants and suffocate from lack of fresh oxygen.
Ahhh Brian, in the summer you can easily alleviate your worry about 'lack of oxygen' by installing a Coolerado air conditioner... notice it's on the PopSci Best of 2009 list under Green Tech. The Coolerado is a fresh air induction system. Further, nobody has ever suffocated in a house from the indoor home pollutants reaching a dangerous level. Obviously always make sure to have smoke detectors and a CO2 detector if you have a gas furnace. Houses naturally 'breath' and I'm sure you open the door several times a day even in the winter. Nature will equalize pressure, oxygen, etc. Your fears are unfounded good sir.
