Construction is set to begin on a $150 million-plus solar powered greenhouse in South Australia’s Port Augusta

John [jpratt27] has published an excellent summary of a new plan to develop a new solar-powered greenhouse in South Australia.  This plant will not only produce fresh vegetables but will also be used to desalinate water in a very arid region.  A few more details are needed about how the resulting salts will be dealt […]

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.

Conservation International – A blog to make a difference

One of my colleagues showed me this site today and it looks really good.  This is a link to their blog page.  This group has some pretty high priced help on their roster.  From Harrison Ford to Hillary Clinton, they seem to have the bases covered. One of the environmental movement needs more of is […]

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 […]

Solar Thermal – What to do when the power goes out!

I spent 6 months living in Kathmandu back in the 90s.  It was commonplace for the power to go off each evening for 2 or more hours and to cope with the outages everyone had battery backups and gas-powered generators.  But over here in Canada we have never needed battery backups or generators to keep things running.  […]

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 […]

Failsafe systems for solar hot water

As I mentioned in earlier blog entries, my system has a number of failsafe features to maintain system heat and pressure within tolerable boundaries. In the summer, the system dumps excess heat into the swimming pool, and in the winter it dumps the excess heat into a radiant water heater in the basement. This spring […]

Power Surges and Drops – Causing Electrical Problems?

I don’t know if you have noticed it too, but there seems to be a lot more power outages and surges these days.  I’m not talking about the 20 day variety like the one that hit us during the ice storm, but rather the one and two second ones that seem to come in bunches […]

OpenEI Blog: Solar-powered desalinisation

I just ran across this interesting post about a small (1000 gallon per day) and smaller (80 gallon per day) solar-powered desalinization unit that could be deployed quickly and cheaply in disaster zones where potable water is hard to come by and electrical power even harder to come by.  You can read more about it here: […]

So, what solar equipment do I need to buy (part 1)?

 Solar system components  When you start to think about a solar system, you have to remember that the industry is relatively new in Canada.  It has been used in Europe for decades, but its penetration on this side of the Atlantic has been marginal until recently.  That means that you have to be conscious that […]

But, it’s always cloudy and cold here! What good is solar heat here?

It is a sad fact, but if you don’t get any sun, you don’t get any solar heat.  But even the grayest areas of the country get a significant amount of sun.  Thermomax, a is a Canadian company that uses European technology to provide solar hot water products.  Its web site has done a great job […]

How does solar thermal work?

In my earlier post I discussed how we decided to select solar hot water in our new house, but before we made the decision we had to understand something about the technology so that we could evaluate the options available to us.  In this post, I will be describing the components involved in solar thermal systems in very […]

Solar Hot Water – Not easy, but worth it!

When we bought our new house about 4 years ago, we wanted to be able to take some control over the utility costs so that when energy prices rise, we would have a bit of protection. There are lots of technologies out there that are environmentally friendly, but not all of them are suited to […]
