Refrigeration Innovation: A Cooler Idea to Save Energy

You can make a refrigerator that consumes only 10% of the energy of your current model, runs almost silently, and stores the same amount of food. And you can do it with only minor alterations to an energy-hogging chest freezer. Australian inventor Tom Chalko shows you how.

With all the recent advancements in energy efficient appliances and electronics, manufacturers have been lauded for their hard work at reducing the energy impacts of a typical household.  
 
And it is deserved. Take for instance the refrigerator. Just 20 years ago a typical fridge would burn 800 or more kWh’s per year. 10 years ago that got cut down to 500. Not 350 kWh’s is par for the course.
 
But every now and then, someone comes along with an innovation so simple, and so brilliant (in that hidden under your nose kind of way) that it makes all the hard-earned advancements seem moot. For the refrigerator, that someone is Australian inventor Tom Chalko (PDF).
 
He had the idea to convert an old chest freezer (a known energy hog) into a SUPER high-efficiency refrigerator using nothing more than an internal thermostat hacked into the compressor. The result is a almost nonexistent 100 watts per day (the equivalent of a 100 watt light bulb going for an hour). That is approximately 1/10th the energy use of the most energy efficient (standard size) refrigerator currently on the market.

Plants & Pests: Will Bonsall’s Advice on “Wee Beasties” in the Garden

“From a plant’s point of view there is little difference between a cutworm, a woodchuck, a blight spore, and, for that matter, us.”“These are all things that in one way or another prey upon it. It is an inevitable constraint of all living things: We escape one peril only to ultimately succumb to another,” so […] Read More
