Don’t we all feel our hearts warmed when we realize that a friend “has our back?” Frankly, I don’t particularly feel that my back needs protecting, but I did write recently:

A radio talk-show host reviewed my book the other day with an eye toward having me on his show. He wrote back just now: … I found it to be interesting, though I should tell you I’m one of the people who don’t believe in global warming….I also believe we have enough fossil fuels to last for hundreds of years if we were allowed to get it … I think it (having you on the show) would make for an interesting segment.

A friend wrote back:

Sounds like a potential ambush to me. I strongly suggest you spend some time memorizing these talking points about Global Climate Change before going on the show.

I’m grateful; I feel very well taken care of. I urge everyone who happens to be interested in the subject of global climate change to check out the link my buddy provided above; it is, IMO the most up-to-the-minute treatment on the subject.

Frequent commenter Cameron Atwood writes:

I’m not sure if you saw this speech by MLK referenced in Chris Hedges’ recent piece, but here’s a link, and it seems as applicable in the present day as it was 44 years ago.

To which I respond:

Chris Hedges is one of the most brilliant minds in our world today.  And by any standards, MLK was a supremely enlightened guy. Was he in Socrates’ league?  I don’t know, but as time passes, it becomes ever clearer that the world is forever a better place because he was here.

To whatever minuscule degree, I wish to die believing the same about my own presence here.  And as an off-the-charts coincidence, I came across this quote twice in the last 24 hours:

“Be ashamed to die until you have won some victory for humanity.”

– Horace Mann, address at Antioch College, 1859

That’s a fairly cool standard to which to hold oneself, don’t you think?

[youtube http://www.youtube.com/watch?v=44EaTcV_-4o]Here’s an interview in which I discuss a company that appears to have made a considerable breakthrough in zinc-air batteries, enabling the sale of product at $160/kWh. If this is “for real,” which I believe it is, the potentials are enormous, for a number of reasons. First, it makes possible, for the first time, the storage of electric energy in large-scale for the power utilities, in turn allowing us to bring more renewables into the grid-mix. At the same time, think of what this means for electric transportation, where a huge percentage of the cost of an EV is its battery pack. Of course, price is not the only consideration – especially when it comes to EVs – but the other characteristics look acceptable as well.

Of course, the world has every right to be skeptical of the company and its claims, having seen zinc air batteries “trotted out” every year or so for the last four decades, and investors have been routinely disappointed – and in some cases actually duped. The issue is optimization. It’s easy to optimize one parameter, but at the expense of others. I’m reminded of the old saw: “You want it inexpensive, soon, and of high quality. Pick any two.”

But again, I happen to believe these people have made the breakthrough they claim. “The only thing it has in common with past efforts in this arena is that it uses zinc and it uses air; everything else about the design is unique,” the company’s president told me when I first met him in his office in New York a few months ago.

[youtube http://www.youtube.com/watch?v=fmoVgU93Z44&w=420&h=315]

In this interview, I discuss a radical new approach to run-of-river hydrokinetics where the water is falling far over a short distance, e.g., a waterfall. The company’s solution is extremely straightforward and would be easy for a wily competitor to steal; it is for this reason that they play their cards very close to their vests, and have gone to an almost unimaginable extent to patent their IP internationally. Will anyone win here – besides the patent attorneys, that is? I believe so.

There are many sites around the world where this solution is perfect, and will produce totally clean power, 24/7/365 at an incredibly attractive rate in terms of levelized cost of energy (LCOE), meaning the average cost per kilowatt-hour when all factors are taken into consideration: the construction, the fuel, operations and maintenance, and decommissioning.

PhotobucketA radio talk-show host reviewed my book the other day with an eye toward having me on his show.  He wrote back just now:

It most certainly will be an interesting segment. I always try to be polite with everyone, and especially so when I’m on the air, but if the subjects of the science of climate change and peak oil comes up (and one has to think it’s likely they will) I propose to ask the host to provide his background in climate science and geology. If, as I suspect, he has none, I’ll gently point out that I honestly don’t understand how intelligent people like him have beliefs that diverge from the commonly accepted positions of science.

I know there are people who believe in astrology, or that the Earth is hollow, as examples. But why? All I know – or think I know – about cosmology or geology is what I’ve read in textbooks in school, or in papers more recently, which are essentially digests of the positions of modern science.  And here, the preponderance (to say the least) of the evidence regarding the formation of the planets would suggest that a hollow Earth isn’t at all likely.

I would even go so far as to say that I’m incapable of seriously entertaining an idea that flies in the teeth of all this.  Shouldn’t anyone be?

Personally, I defer to the thousands of scientists who have spent their lives studying the issue, noting that 97+ of them think that global climate change represents a serious threat to life on Earth.

The work of all these people means something to me.  Why did we study science if we intended to ignore it?

PhotobucketOn Sundays I like to take a hike of 6 or 7 miles, sometimes including a stop-off at the Ballard Inn, where I sit on the porch and read the Sunday paper. Relaxing there yesterday afternoon with a glass of lemonade, I came across this Doonesbury cartoon on global climate change, which I thought I’d bring to readers’ attention, as it’s another example of Garry Trudeau’s hilariously keen insight into the ways of the world.

In my opinion, Trudeau is a genius, and has more than earned his position as one of the world’s most esteemed social and political satirists. It will be a sad day for the world when he retires.

[youtube http://www.youtube.com/watch?v=52yfsAihk3Q]In this short video, I discuss a new twist on pyrolysis to create high-grade biodiesel from a stream of waste-tires. Some of the many appealing aspects of this approach are:

1) It’s modular; each plant costs less than $5 million to build.

2) The technology is proven; it’s been running 24/7 in the Ukraine for the past two and a half years, and

3) It’s “omnivorous.” It’s very easy and quick to convert to another feedstock if necessary.

Clean energy investors interested in pursuing this should let me know.

[youtube http://www.youtube.com/watch?v=3V3DnBFkUec]Here’s a short video in which I discuss a terrific investment opportunity I’ve encountered — a wonderful design for an electric bicycle. Even the “EV doubters” believe that e-bikes are going to become an increasingly important component of transportation in the world’s ever-more congested urban areas, and in my estimation, this design is destined to become super-popular.

Why Are Investors Bearish on Clean Energy?I called my friend, 2GreenEnergy Associate and clean energy finance expert Bill Paul for some advice the other day. “I have a client with a breakthrough in battery chemistry, and I’m trying to find them a manufacturing partner in the electric vehicle space.  Where do you think I should look?” I asked.

By the word “where,” what I meant was “At what companies?” But what I got from Bill was this: “My first suggestion is that you forget everyone and everything in the United States.” (more…)
