Have you ever heard of the concept of an “Earthship“? I was introduced to the concept by my brother-in-law about 14 years ago and was blown away. What is an Earthship then? In a nutshell, an Earthship is an Eco-friendly home, made predominantly from recycled materials, designed to be as close to “off-grid” as possible.
The concept of Earthships arose in the halcyon flower-power days of the 1970s in various states in the southern USA. The concept seems to have developed by Michael Reynolds, an architect from New Mexico. As you can see in the linked Wikipedia article, his idea was not without problems, but it was, none-the-less revolutionary. Michael has a website where he educates about, demonstrates and promotes the Earthship technology. The site has designs for a number of systems that an Earthship needs if it is to meet code (see figure 2, below). Continue reading What the heck is an Earthship? … maybe an idea whose time has come!→
I often hear pundits decrying the aggressiveness of drivers. It is hard to disagree with the premise that aggressive driving is bad, but the picture isn’t as simple as the pundits would have you believe.
For one thing, not all aggressive driving is “actively aggressive”. The pundits rarely discuss the passively aggressive drivers, like the folks that drive in passing lanes. They also often fail to look for root causes for the driving aggression.
I have been thinking about this issue for a long time and think I have a few suggestions on how to reduce aggressive driving. My suggestions are in the form of tips and I have organized these suggestions around four possibly overlapping groups of people … 1) the aggressive drivers themselves, 2) traffic planners, 3) other drivers and 4) law makers. There probably isn’t much new here, and I hope it doesn’t appear to be condescending, but aggressive driving is an issue that has been bugging me for years so I wanted to add my two cents to the conversation.

The City of Ottawa has a nice new web page that acknowledges the existence of solar energy, and in particular solar domestic hot water (SDHW). The site, which can be found on ottawa.ca gives information about two different types of SDHW systems: a CSA approved factory packaged system and not factory packaged system. Both types of installation need a building permit.
Both installation types must be installed by a qualified installer (CanSIA certified) but non-factory packaged installations must be certified compliant with CSA F379.1-09 (the reference standard for SDHW) and with the Ontario Building Code by a professional engineer licensed in the Province of Ontario.
This doesn’t sound like a lot of help, but when I had my solar system installed, there were no guidelines or standards available and we had to slog through a morass of bureaucracy to get our installation approved, so that guidance is very welcome.
This information should make the process of installing SDHW more transparent and it should really reduce some of the risks to the homeowners and installers. Good job Ottawa!
