Fraudulent Clean Energy IdeasA woman from the Los Angeles area contacted me the other day about the all-new “wind car.”  I had hoped to see something interesting, but no, it was as I feared: a chassis on wheels with a battery and the fan on top that supposedly charges the batteries.  She directed me to the fellow who’s raising investment capital to build and sell the idea, and he told me, “It’s not good that electric vehicles have a limited range.  You can drive this to New York.”  (more…)

Carbon Dioxide and Climate Change Denialism

A friend sent me this piece on CO2 concentrations in the Earth’s atmosphere, and writes: FYI just in case you have not seen this.

Yes, that’s interesting. As I may have mentioned, I know a few of these people personally, e.g., Professor Ramanathan (he goes by “Ram”) at the Scripps Institute (pictured below) here in Southern California. (more…)

Yet understanding renewable energy, and certainly all the terms and jargon that fit around solar energy, isn’t entirely easy. That’s why this article hopes to debunk and hopefully explain to you, in more simpler terms, what things you should know if interested in powering your home by solar means. (more…)

It is now fashionable to drink your favourite beverage out of a paper cup labelled as eco-friendly, but what does a label like this really mean and what are the implications once the drink has been consumed? (more…)

Like All Aspects of Long-Term Environmental Damage, The Cost Ocean Acidification Is Hard To Nail DownSince the Industrial Revolution, the pH of the oceans has declined from 8.2 to 8.1, largely due to the absorption of CO2 and the formation of carbonic acid.

What’s a lousy 0.1 in the scheme of things?

Green Building Trends in Australian ArchitectureRegardless of all the marvels man has achieved in the past, it is the sad fact that we as a species most often blindly follow the mainstream in any art and cultural form, frowning on all those who think differently. This is why someone observing modern global architecture would conclude that there are only three construction materials used in modern architecture. (more…)

Capturing Carbon in Useful ProductsA very bright reader “BreathOnTheWind” (love the name!) comments on my post on carbon sequestration:

Somewhere deep in the core of my being I feel that the answer for carbon must be to find a use for it. If carbon becomes a useful consumer and/or industrial product then dumping it in the atmosphere would be to ignore a revenue stream. I am seeing some possibilities for this. Batteries and other materials are being made with the newly created material graphene. This is a pure form of carbon. Also there are recent articles that suggest carbon fiber could become a very important manufacturing material for automobiles. (more…)

When It’s Climbing a Mountain or Installing Solar PV, We All Accomplish A Great DealAs a result of attending my college class’s 35th reunion in 2012, I somehow was appointed “class secretary.” This means that I’m about half way through a five-year term in which, every three months, I gather, edit, and aggregate notes from anyone wishing to tell the world about his/her exploits since our graduation in 1977.
