Right after the inception of 2GreenEnergy almost exactly 10 years ago, I made a few clean energy infographics and promoted them, especially for use in schools.
I never did one on climate change–and I’m glad I didn’t, now that I’ve seen this masterpiece. (more…)
The sign here hasn’t tolerated Santa Barbara’s seaside weather too well; the top-most section in Spanish is mostly peeled away, and the bottom, in Arabic, is splashed with mud. I present it nonetheless, to make the point that the people here tend to be kind and gentle, not to mention intelligent and well-educated. (more…)
It’s shocking how little most Americans know about cities outside the U.S. The Russian city of Arkhangel’sk has a population of more the 350,000, roughly the size of Anaheim, CA; New Orleans, LA; St. Paul, MN, and Cincinnati, OH…..yet I doubt that one person in a thousand here has ever heard of it; I certainly hadn’t.

When analyzing Tesla’s outselling Porsche on the Continent, one could say that the latter is a brand of car whose bloom is off the rose. Far off. It was fashionable in the 1980, at least in California, to show off your Porsche on our enormous network of freeways. As suggested in the photo here, guys bought them to attract (shallow) girls, and presumably had great success. (more…)
The chart below staggers the mind, if only insofar as it makes us think about the $6 trillion we’ve spent in Iraq and Afghanistan, and what we could have done with that money. (more…)
In a ruling last week, King County Washington Superior Court Judge Timothy Bradshaw found that “Comcast violated the Consumer Protection Act more than 445,000 times when it charged tens of thousands of Washingtonians for its Service Protection Plan without their consent.” Each wrongful monthly charge was a separate violation, so, in most cases, there were multiple violations per customer.

Here’s the way I like to explain building integrated solar PV (BIPV): “It’s not on the roof; it is the roof.” This is clearly destined for greatness over the coming years, especially as more states and other countries follow California’s lead in requiring net energy neutrality for all new construction.
Having said that, there are good designs and bad ones. The one shown above looks both light weight and as efficient as possible, given that the PV itself covers most of the roof surface.
The same can’t be said about the design on the right; looks like a loser in the marketplace to me.
Here’s a video on the proposed use of piezoelectricity (electric power produced when mechanical stress is applied to certain crystals) in walkways. This is a neat concept, but it’s extremely impractical, with the possible exception of extremely highly trafficked areas, e.g., the doorways to and from Grand Central Station in New York City. (more…)
At this point, Biden is almost as abhorrent to environmentalists as the Republicans are, principally because of his tepid response to climate action, which, presumably, he adopted so as not to alienate conservatives. It would be far better for the vast majority of Americans if everyone wishing to defeat Trump were to rally around a true progressive. (more…)
I get submissions from readers that “challenge” the laws of physics at the rate of four or five per year. Over time, I’ve become kinder to such people in my replies; I used to be fairly brutal, but there’s no reason for that.
A gentleman from Germany writes: Attached are some documents that explain how this gravity-powered engine works, and provides a scientifically fully proven theory that allows such devices to be built. (more…)
