Does the Mercedes Concept Car (F 015) Represent the Future of Transportion?

Does the Mercedes Concept Car (F 015) Represent the Future of Transportion?  Since the Mercedes-Benz F-015 is an electric vehicle (with both batteries and fuel cells), one might think it would have EV fans dancing for joy about this incredibly futuristic car. And the language that Mercedes uses is certainly lavish enough: The result is more like a carriage than a rocket ship. Passengers “inhabit” the Mercedes-Benz F 015 rather than drive it, and the interior has the visual cues and physical features of a mobile office rather than the usual jet-fighter cockpit.

Personally, I’m betting against all this extravagant use of interior space for even the wealthy (actually, extremely wealthy) consumers to “inhabit.” Read more ›

Smart Money Isn’t Betting Against Tesla Motors

Smart Money Isn't Betting Against Tesla MotorsTesla Motors’ stock price may be a volatile as the devil. But it’s steady drumbeat if innovation and promotion sure isn’t. Here’s the latest in what they’re saying about their network of charging stations that require you to pull off the road for as little as 20 minutes: Superchargers enable long-distance travel for free, for life.

That’s some powerful and concise language there. Read more ›

Taking Good Ideas In Cleantech Forward: One Can’t Please Everyone

Taking Good Ideas In Cleantech Forward: One Can’t Please EveryoneI hope readers here check out the comments as well as the posts themselves; there really are some good ones.

Frequenter commenter “MarcoPolo” has some pretty right-wing/libertarian beliefs, and, as I’ve told him, “We just need to “agree to disagree” on most points in terms of political philosophy—and even most of the science associated with sustainability.”

Having said that, I normally try to read all comments carefully, especially when they counter my beliefs, to see if there is some concept from I might benefit.  We learn most from our efforts to disconfirm our beliefs, rather than hunting around for things that support what we already think.  Read more ›

Outlook for Geothermal

Outlook for GeothermalA colleague mentioned that he was one of a large number of investors who had lost money in Raser Geothermal in the 2000s (the “aughts”).  I’m well aware of how little talent is required to be a Monday morning quarterback, but from what I know of the pros and cons of geothermal generally, this sounds like it was a bad idea from the beginning.

The concept behind Raser was compressing the timescale required to get a geothermal plant operational by doing the drilling and the plant construction at the same time.  Read more ›

Offering Concepts in Sustainable Energy Here Is, In Fact, Preaching to the Choir

Concepts in Sustainable Energy Are, In Fact, Preaching to the ChoirIn response to my recent piece: In Terms of News and Ideas, Most Americans Live on a Bizarre Little Island, my colleague Bob Huff writes: You’re preaching to the choir. I couldn’t agree more. US news in just one new distraction after another to avoid having to address real, resolvable issues (which require an understanding of facts).

Bob: Yes, unfortunately, “preaching to the choir” is an unavoidable aspect of this 2GreenEnergy enterprise; I get unsubscribes from people who think I’m Chicken Little cum Leon Trotsky, Read more ›

Great Statements Have Their Own Beauty

Great Statements Have Their Own BeautyWe all have a certain appreciation for statements of important facts that are so concise and finely tailored that the words themselves offer a profound beauty.  Students of the U.S. Civil War recall the ceremony at which Lincoln delivered the 273-word Gettysburg Address, which followed a much longer speech made by one of the most well-regarded orators in history, Edward Everett, consisting of more than 13,000 words and lasting over two hours.
