It’s the birthday (1632) of the philosopher Baruch Spinoza, whose most important ideas, according to the Writer’s Almanac, were that “everything in the universe is made of a single substance, and that everything in the universe is subject to natural laws. He also argued that the soul and the body are not really separate, but two parts of the same thing. He believed that God did not stand outside the universe, but rather that the universe itself was God, and that everything in the universe was perfect and divine.” (more…)

Every day, it seems we read more about hydrogen fuel-cell vehicles, most of which appear to be written purely to further confuse people who don’t really understand this in the first place.  An excerpt from the article linked above: “Fuel-cell vehicles …. can operate on renewable hydrogen gas.”  As the author must know, the concept of “renewable hydrogen gas” has no meaning at all.  (more…)

I’m sending a “2GreenEnergy Alert” (e-newsletter) to our subscribers in a few minutes with the subject line: “Cashing in on the Skyrocketing Electric Bicycle Market.”  I’ve just added a company in Seattle with a unique approach and capability to the retail e-bike space to our list of clean energy investment opportunities, and, even though the amount of cash required is tiny compared to some of the larger deals, I think this is an exciting opportunity for the right person.

Here’s an article that discusses the compass direction that solar panels should face, both to maximize total power and to create the optimum alignment of peak generation with peak load. Although I found this interesting, the most intriguing part is this: we’ve had solar panels on our roofs for 40 years and we’re just now figuring out which way to aim them? I guess I too would also assume it best to point them in the direction of the equator, i.e., south if you’re in the Northern Hemisphere,  but it seems a bit strange to be having an epiphany on this as we go into 2014.

Here are a few words on the climate talks in Warsaw, based on yesterday’s New York Times article – just a few – since I have nothing constructive to report, nor, in my heart of hearts, do I think any level of accord is even remotely possible.  As always, the talks bog down between rich and poor nations on the question of who should pay for relief for climate-related disaster.

I’m working with a young writer who aspires to publish content on OTEC (ocean thermal energy conversion) on a number of different high-profile sites, so as to educate as many people as possible on the subject, and to drive traffic to the hot new website EmpowerTheOcean.com.  I thought readers may be interested in what I’m advising him to do:
