What the heck is an Earthship? … maybe an idea whose time has come!

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).

Scientific American Article about the Dangers Associated With CF Light Bulbs

Scientific American Article about the Dangers Associated With CF Light Bulbs As a follow-on to my earlier article about various technologies for lighting your home, I wanted to post this link.  As the date for conversion of all light bulbs from incandescent looms near there is a lot more is being said about the safety […]

Solar Lights Recycling | Your Solar Link

I am constantly looking for good environmental blogs and have been following a really good one lately named “Environmental world for all”.  The site is authored by a university student in peace studies with minor in environmental studies. One of the author’s recent posts discusses the benefits of solar LEDs for use as Christmas lights.  It is a […]

Hybrid cars – one buyer’s thoughts

Back in 2009, my family bought a 2010 model year Honda Civic Hybrid. The chart in the dealership, which was produced by an independent tester, gave the Civic a rating of 60 miles per imperial gallon (mpg) in the city and 66 mpg on the highway. A review of the Natural Resources Canada (NRCan) website […]

Solar light bulbs for pennies (Isang Litrong Liwanag/a litre of light)

A litre of light

I just ran across a wonderful innovationthat seems to have been around for a few years but just now seems to be garnering widespread attention. The innovation seems to be the brainchild either the Massachusetts Institute of Technology or of Mr. Illac Diaz of the Philippines. It is as brilliant in its simplicity as it is as a light bulb. I am going to leave the description of the “bulbs” and how they are used to the foundation (and to two interesting YouTube videos (describing the why and how). One of the linked videos below describes this as an idea out of MIT and that makes sense because that institution seems to focus on a lot of simple projects to help the poor (see my earlier blog about solar powered water desalinators that were developed by MIT folks).

City of Ottawa – Help for Folks Installing Solar Thermal

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 […]

How do you decide which green technology to use to light your home.

One thing that has always bothered me about being an environmentalist is that there is never enough good information available to the consumer allowing them to make intelligent decisions.  Case in point … what kind of lightbulbs to use in the house to reduce the total carbon footprint and to be generally green.

For years now, we have been asked to consider moving to compact fluorescent lightbulbs because they last longer and they are far more efficient than the incandescent bulbs we have used for the last hundred years or so.  Continue reading “How do you decide which green technology to use to light your home.”
