Air infiltration into your house is the number one enemy of your home heating and cooling efficiency. Wall switches and electrical outlets which are located on the exterior walls of your home can serve as ports of entry for outside air. Insulating these potential thermal leaks is simple and cheap to do.

You can get inexpensive foam outlet seals at any home or hardware store. They are simple die cut foam shields which go between your outlet plate and the wire box in the wall. These foam insulators can potentially shut off air leakage entering your home from behind switches and outlets.

The process is simple and goes like this:

Would it not be living in the world of perpetual bliss to be able to flick a single switch that could turn off your entire house during your hurried morning routine? Well, not the fridge or air conditioner, but just about everything else that's considered non-essential?

Not only would a product like this save an untold reserve of energy that's being needlessly drained from nearly 99 percent of homes across the world, but it would be the ultimate green hack. When you get home, just flick the switch again and everything comes on. How proper!

Would the market be interested in something like this? I think so, as the ranks of the eco-conscious continue to grow in the face of incessant global warming and iceberg-melting media coverage. If only electrical system designers would make this an option on new homes, I think many would opt for it. What do you think?

Are you one of the millions who tosses away a good portion of the day sitting in traffic and wasting inordinate amounts of time during the process? Welcome to the club, as recent reports state the average San Jose citizen wastes up to 54 hours per year just sitting in traffic. I think the total is easily more than that, and if you've driven in Silicon Valley traffic before, you're probably inclined to agree with me. In other areas, the figures range from 20 hours to 70 hours per year. Bleh!

Hey, we're not yet to the point in the future where flying cars ala' The Fifth Element have arrived, so what is the solution? If you're into cheating the system, how about a way to gain access to all the green traffic lights that you can? If you're into reducing the number of stops your lane of traffic has and you drive a smaller car, truck, scooter or motorcycle, listen up.

For about $6 or so, you can probably score some 3M exterior mounting tape and a pair of small neodymium magnets. With those two items, you'll fool most current traffic stop induction systems into thinking that Scion is a Ford Expedition -- and with that disguise, you'll gain access to much faster green lights. I'm trying this one soon after a short trip to the nearest Home Depot. Get the dibs using the below video. (NOTE: This may be illegal where you live!
