With the first-floor walls poured, it's time to erect the structure for the rest of the house before my panels show up. Does this look a little overbuilt? Well, there's a very good reason why folks don't build flat-roofed houses in the Great White North: It's called snow, and it's heavy. It makes little sense to design a house that would allow snow to sit on the roof, stressing the structure, instead of just sliding off.
Even though I spend most of my time thinking about geothermal heating systems and backyard solar plants for my green home, in the end, a house is a house; holes must be dug, foundations must be laid, steel delivered and erected, and so on. Here's a look at our progress in that less glamorous but wholly necessary department.
Any green home worth its weight in compost draws heavily on solar energy. Mine is equipped with all the standard offerings, such as a solar-powered boiler, the subject of my last column. Trouble is, the sun doesn’t always shine. So to make up the difference during cold, dark winters and rainy spells, I’m turning to another eco-friendly energy source: my backyard. The two 325-foot-deep geothermal wells I’m boring there will use the constant 50°F temperature of the Earth at that depth to meet all my extra heating and cooling demands.
Next week I’m going to build the primary steel staircase for the house. Over the last 24 hours the design has changed more than three times. It’s not that I don’t know what I want, it’s just that I have a crazy architect, Timon Phillips, and an even more crazy friend, Vin Marshall, who engineered and designed what I’m calling the “mouse tower” concept and will be welding it with me. (Lesson one of a DIY build: If your friends are as nuts as you are, nothing in your home is going to be normal or easy.)
Polaris has just introduced an electric version of the Ranger 400 side-by-side. This is very exciting to me. As you may remember, I'm the guy who built a rather non-green jet turbine side-by-side, but 114 dB does get old after a while.
Every home needs lights. But for the Green Dream? Forget copper wire between lights and light switches, three-way switches and batteries; I’m looking at Verve’s lighting control system—-a wireless solution that uses radio frequencies to control a home’s lights, allowing you to put your light switches wherever you want--on your wall, in your pocket or even the dash of your car.

No, it's not a death ray. The folks at RawSolar are creating what looks like a very affordable solar thermal tracking dish. This is a mini version of the concentrating solar power systems you see commercially in the 25 kilowatt range.
Pre-fab panels instead of a wood frame save cash and energy

In the past 20 years, I've lived in some pretty weird places — a leaky loft, a sailboat, an old carriage house that I rehabbed myself. Makeshift bachelor pads were fine until I found myself with a wife and two small boys.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
