Go Green Expo, Part 2: Hanging out with Matthew (Modine) and Ed (Begley, Jr.)

Green Is King!

On the second day of New York’s Go Green Expo, the first day in which it was open to the general public, the place was packed! On an almost freakishly beautiful March Saturday, with the temperatures climbing at least twenty degrees above normal, hundreds of people chose to spend their day off right here, at Pier 92, to check out the cutting edge in sustainable living for every aspect of their lives.

However, I couldn’t allow myself to be distracted because I didn’t want to miss the “star” speakers today. Now, I should clarify my position here vis-a-vis the Celebrity Thing. Some years ago, I worked — and believe me, it was work — as an extra in movies, on TV and in commercials, so I was rubbing elbows with famous people on a daily basis. And the big names generally didn’t impress me very much. I mean, it’s really hard to have much reverence for a person, no matter how well-known, while observing him or her pouncing on the food from craft service with the same shameless gluttony as oneself. But activists do impress me, and I’m fascinated by the combination of show-biz success and sincere ideals. And today’s program offered not one but two such stars: Matthew Modine and Ed Begley, Jr. Indeed, the latter has become as famous for his environmentalism, if not more so, than his (non-reality show) film and TV credits.

Mr. Modine, who was sporting an impressive beard (he’s currently appearing in the Broadway production of The Miracle Worker), spoke to us about two topics: the fortieth anniversary of the first Earth Day, with a current campaign to drive the movement forward called the “E Campaign,” and an organization he founded called “Bicycle for a Day” to encourage city dwellers to use bicycles rather than motor vehicles as their main source of transportation.

To that end, he showed a brief video of himself (sans beard) happily bike-riding around New York City — without a helmet. Afterwards, poor Matthew was taken to task by an audience member for his lack of headgear, and she refused to let the issue go, taking up Modine’s, and the audience’s, valuable time. Hey, lady, I wanted to say (but didn’t), you’re way off-topic: this is an environmental expo, not a personal safety expo!

When Modine was finally allowed to talk about what he came to discuss, he had interesting things to say. He observed that the 200-plus-year-long Industrial Revolution, which has been responsible for transforming the earth and which now threatens our very lives, is but a split-second in the geological history of the earth, which is itself but a moment in the history of the universe. He seemed to be saying that the things we think are so important are actually insignificant in the great scheme of things, and we can begin to turn things around when we realize that.

He gave an effective answer when someone asked him about Obama’s nuclear policy: “It’s a temporary solution to a permanent problem.” He pointed out that, even if the proposed plants actually get built, aside from the problems involved in the dangers of uranium mining and of nuclear waste, there exists only enough uranium to supply our energy needs for 20 years. “Should we spend billions of dollars for 20 years of energy?”

Modine also had another intriguing idea: instead of bailing out the auto industry, subsidize it to switch from the manufacture of autos and trucks to light-rail transport. In the 19th Century, not only America but relatively non-industrialized nations like Russia sacrificed to create viable rail networks in their countries. Those networks were themselves sacrificed to the almighty auto. It’s time for America, said Modine, to revive this cleaner mode of transport.

After his talk, when I asked him my standard question (“The future of solar is…?”), Modine answered, “The future of solar is almost eternal energy.” He clarified by pointing out that the sun, like all other heavenly bodies, must one day become extinct. Hey, I’m not like little Alvy Singer in Annie Hall: I’m more than happy to concentrate on life on earth in the next eon or two, and let what comes afterwards take care of itself!

I was expecting no less than an outstanding presentation from Ed Begley, Jr. — and he did not disappoint, in either the informational or comedy departments. He began by pointing out that his marriage to his beloved wife Rachelle boasted the only pre-nup agreement to include carbon credits. He also complained because his wife accused him of being insensitive to her needs, just because he bought her a hemp thong for her birthday. Talk about petty!

He soon turned serious, but not solemn. Surprisingly, he did not attempt to refute the climate change deniers (of which there were most probably precisely none in that audience). Instead, he focused on assertions that were totally non-controversial. He began with the adverse health effects of air pollution around the world, as well as the contamination of ground water with such substances as benzine, pesticides and herbicides. He reminded the audience of how the Cuyahoga River in Ohio caught fire from pollution in 1969 and how fisherman on the Hudson came back from the Vietnam War only to find themselves unemployed because of river pollution.  

Yet, unlike most environmental prophets of doom, he took care to point out the good things that have already happened. Thanks to the Clean Air Act, the smog in L.A. has been cut in half. Due to the Clean Water Act, rivers no longer catch fire and the Hudson (though far from ideal) is much cleaner. Even the hole in the ozone layer has shrunk.

“If we do this [environmental reform] smart, we won’t go broke!” What is good for the ecology may also be good for the pocketbook, Begley insisted. He recalled the first Earth Day forty years ago, and said that part of the reason he chose to participate in that event was to honor his (Republican) father, the wonderful actor Ed Begley, Sr. , whose conservatism ironically taught his more liberal son how to conserve.

As a poor struggling actor in the 1970s, he entered the green lifestyle modestly. His electric car was more like a glorified golf cart. Yet it was cheaper to plug it in than to buy gas for a “real” car, and it required practically zero maintenance. He bought a solar oven, then bought solar-powered water heating in 1985 (when there were no subsidies). Finally, he went all the way and got solar electric in 1990. But his ultimate innovation was to build a fence for his house out of recycled (white) plastic water jugs. (Actually, I had seen this infamous fence in the charming film Pittsburgh with Begley and Jeff Goldblum, and wondered at the time if it was for real.)

Begley summed up his message as “don’t ever be discouraged.” He pointed out the two lies about the environment currently being promulgated in the culture and emphasized that both of them must be fought:

  1. There really is no environmental problem;
  2. There is an environmental problem, but it’s too late to solve it.

Alluding to the Climategate so-called scandal, he compared it to the O.J. Simpson trial, in which Mark Furman’s behavior was enough to get all his evidence against the former athlete thrown out. Thus, some “wacky emails from East Anglia” were enough for some people to conclude (falsely) that the whole climate change evidence was fraudulent.

Referring to the theory that the melting of the polar icecaps are due merely to natural causes, Begley pointed out that, even if one accepts that idea, everybody knows that human-made CO2 would make such “natural” warming even warmer. “Why put a feverish patient in a sauna?” he asked.

He strongly disagreed with Obama’s stance on nuclear power, because:

  • “I don’t want more fissile material for people to get their mitts on;”
  • Nobody wants either a reactor or nuclear waste near where they live; and
  • Both people and computers make mistakes.

Asked whether the cost will come down on solar panels, he said he thought the price would become much cheaper than before. But he said that this would probably happen with solar panels covered with amorphous coatings, which are indeed less expensive, but also less efficient.

Begley said several things with which I disagreed, such as his comments in favor of cap-and-trade, but at the end I gladly joined the audience in the enthusiastic applause. Yet when I headed for the booth where he was signing copies of his book, Living Like Ed, I felt some trepidation. Would he be annoyed that I did not buy a copy for him to sign, since I am, as they say, “in transition,” and thus could not really afford to purchase it?

I greeted him and he warmly shook my impoverished book-free hand. I asked him my standard question.

“The future of solar,” he said, “is government subsidies to move things along quickly.” Then I took his picture (twice) and moved on to make room for the next person in line.   

I should point out that because of a problem either with my camera itself or (more likely) the lab to which I brought the film for development, my pictures of Matthew and Ed unfortunately do not exist for me to grace this blog.  You have only my report of the event to go on. But I think I have conveyed how interesting and inspiring it was.

Go Green Expo, New York City, Part I

The first day of the New York edition of Go Green Expo took place yesterday (3/19) and at the very least it demonstrated for me the extent to which green consciousness has permeated our culture. (This day was dedicated solely to businesses and the press and was not open to the public; Saturday and Sunday, the expo is open to everybody.) “The nation’s leading eco-focused, interactive green-living showcase,” as the press material describes it, housed in a gigantic space at Pier 92 in the far west side of Manhattan, contained areas devoted to Energy & Conservation, Home & Building, Travel & Transportation (including some very nifty-looking cars), Business & Electronics, Health & Beauty, Foods & Beverages — even a Kids Zone. “Go Green Expo focuses on going green without sacrifice [emphasis mine].” (I am a bit skeptical about that last part: assuming such a thing is desirable, is sustainability without sacrifice even possible, at this late date?)

Solar power was not slighted at this event. Walking in from the registration area, I came upon the booth for Mercury Solar Systems, which is headquartered in Port Chester, New York, but also has offices in Connecticut, New Jersey and Pennsylvania. and describes itself as “one of the leading solar integrators on the East Coast.” The man behind the counter, David Weiss, was a most upbeat fellow, very enthusiastic about his product. Asked how he got into the business of solar, Weiss said, “I wanted to sell a big-ticket product that was good for the earth and also fun to talk about, though for a while, I wasn’t sure what that product would be.” To the question of how he overcomes customer resistance to solar power, he cited what he considered the three main customer misconceptions:

  1. The Northeast is lousy for solar;
  2. The technology is too expensive;
  3. It looks ugly.

Weiss was happy to refute all of these assumptions (he thinks the Northeast is actually better for solar than Florida). He also refuted another argument buyers use to postpone installing the technology: that some amazing breakthrough in solar tech is just around the corner that will make it much cheaper and/or more efficient and that therefore they should hold off on buying solar until after this great event occurs.

“It’s not going to happen,” said Weiss. According to him, “in the last 20 years, solar energy has only gotten one or two per cent more efficient.” He said that the important things for the salesman to accomplish are to explain the rebates that are available through state legislation, and make people understand that there is no point in waiting. Asked when solar sales will start skyrocketing, he answered, “They’re skyrocketing now.”

Bill Wang of American Renewable Energy (ARE) (“one of the leading solar integrators on the East Coast,” as its brochure states) also believes that the main problem is educating the buyer — as well as government officials. To that end, he has been in touch with the mayor of Philadelphia to try to increase awareness of how the city can adopt solar power. The company sees itself as “a bridge between traditional ways and a renewable energy future.” To that end, he is willing to partner even with the fossil fuel industries, oil and coal, to try to get them to “come on board” the solar revolution. He predicts that by 2013, 22%, over one-fifth, of homes will be powered by some form of renewable energy. Asked why they are doing this, Mr. Wang said, “to benefit our children and grandchildren.”

An outfit called Solarrific had a booth containing all kinds of imaginative solar-powered (and dynamo-powered) gadgets. These included a stick light that changes color and a tile light, both designed to illuminate outdoor areas (such as a garden). There was a solar-powered battery recharger that worked with AA, D and 12-volt batteries. Most interesting was a solar-powered bug zapper that works both indoors and outdoors. (This seemed to me a good alternative to those aromatic flying insect killers that can only be safely used outdoors.) Other things Solarrific marketed included a solar water fountain kit, a combination cell-phone-charger, light and solar panel, and a solar caddypack.

A pleasant French fellow by the name of Patrick of Solar LED Innovations sold very elegant-looking solar-powered flashlights and tube lights, which doubled as cell-phone chargers. They were manufactured by employees hired from Handi-Crafters, a service whose clients are developmentally disabled. When I asked Patrick about the future of solar, he said that solar was now the most dynamic form of renewable energy. He pointed out the often-cited statistic that solar power use has been rising 50% annually, in effect doubling every two years. He said that solar is becoming more affordable and that new creative uses are being found for solar power all the time.

The last word of this post belongs to Bradford Rand, the President and CEO of Go Green Expo. When I asked him his opinion of the future of solar, he answered as follows:

The future of solar is omnipresent: a clean, sustainable, renewable energy source that will continue to grow through the 21st Century. It is an area of knowledge that will generate tremendous economic growth and a clean environment and help rid us of the curse of dirty energy.

Of Tasty Cars and Tasteless Politicians: A Tale of Two Energy Conventions

According to all the reports I’ve read on the MIT Energy Conference, held last weekend in Boston, it was really two conferences. Conference One proved that, with the right funding and the right minds to take advantage of it, tremendous things are being done (and even more can be done) in the field of clean energy research. Conference Two proved that, outside the golden world of green tech science, the same old climate change denying and sheer incompetence still reign in the less-than-golden world of public policy.

First the good news: the breakthroughs, real and potential, by MIT researchers, whose work on clean energy tech was praised by Barack Obama last fall, are truly impressive. One team is exploring the potential of particles called excitons, the mechanism for light emission in semiconductors. The goal would be to create thin-film, non-tracking solar cells with power efficiencies greater than 30%. Another team is exploring ways to replace expensive copper parts in solar thermophotovoltaic (STPV) systems with cheap plastic parts. The principle is that, as long as there is some kind of heat source, the cell can generate light, which in turn can generate energy even when the sun isn’t shining.

A third team is dealing with a related problem: energy storage, a major difficulty with intermittent energy sources, like wind and solar. Compared to 15% in Japan, only 2.5% of the capacity of the U.S. energy grid can now be stored. The solution that one scientist has proposed are gigantic liquid metal batteries (to be kept at temperatures of around 700 degrees Celsius) to act as “frequency regulators” that would keep energy flowing to consumers if power from the energy source is suddenly cut off. A fourth team is working on a cobalt phosphate catalyst that would split water into hydrogen and oxygen cheaply. If research is successful, three liters of water could conceivably power a home. This technology would be particularly useful for the developing world, where there is often little or no existing electricity-generating infrastructure.

But the star of the conference was unquestionably… Lola! Lola is a Formula 3 racing car, created by the University of Warwick, constructed entirely of renewables, including carrots, potato starch and flax, and fueled by… chocolate. Developed over 9 months at a cost of $200,000, it has a top speed of 135 mph and can go from zero to 60 in 2.5 seconds. Its engine runs on diesel, not gasoline, and can even run on fuel derived from chocolate factory waste and other vegetable-based oils. Its radiator even converts ozone back into oxygen, literally cleaning up the atmosphere as it runs.

In dramatic contrast to these encouraging — even astonishing — innovations is the decidedly uninspiring, indeed downright depressing state of national energy policy. Of course, we already knew that the facts were grim. But Nobuo Tanaka, who spoke at the conference in behalf of the International Energy Agency (IEA), brought us down even further with his statistics on the state of climate change and what is really needed to combat it. The multi-trillion dollar investment that is needed to stabilize the climate would require, according to Tanaka, the construction and deployment of:

  • 18 nuclear power plants
  • 17,000 wind turbines
  • At least 2 huge hydroelectric plants
  • 94 (I have no idea where he gets that precise number) new solar power plants per year between now and 2030.

And all that is only to maintain the projected target of 450 parts of carbon emissions per million in the atmosphere, which would nonetheless still raise the earth’s temperature 2 degrees Celsius. As I disagree with the viability or safety of nuclear power plants (see previous post), a lot more wind and solar generators than Tanaka’s estimate would be required to compensate. And many activists and others think that 350 parts per million is the only safe target. Yet Tanaka insists that the target of 450 per million is “science fiction” if this massive investment does not take place.

One  of the chief conference speakers was John Rowe, CEO of Exelon, the nation’s largest electric utility company and the owner of the biggest fleet of nuclear power plants in the U.S. He stated that pro-climate government regulation was “in my economic self-interest.” (This statement apparently makes more sense now than it would have a short while ago, since President Obama mysteriously decided recently that nuclear power is renewable energy.) Rowe emphasized that the government should establish and maintain a steady, consistent policy, and the American consumer should understand that there’s no free lunch: combating climate change is going to involve some personal cost. However, he rejected government regulation as a solution. Bringing out a chart of what he called 27 potential EPA regulations, he referred to it as a “train wreck” that would cost utilities billions of dollars and provide jobs only for lawyers.

He asserted that carbon pricing — either a carbon tax, or cap-and-trade (preferably the latter) — was the only way to fulfill the four goals of a viable energy policy:

  • Cleaner energy
  • Greater energy security
  • Job creation
  • Lowest possible cost.

Senator Jeff Bingaman of New Mexico, chairman of the Senate Energy and Natural Resources Committee, who gave the closing keynote speech, brought back the latest news from the Beltway… and it was not good. In contrast to Rowe, he affirmed that clean tech could not be realized without a major shift in government policy, including new regulations. The chances of that happening soon in partisan Washington, however, said Bingaman, are slim. He perceived a pattern whereby the U.S. creates an innovation (e.g., the lithium ion battery) that somebody else then manufactures and profits from. His four-point program for a viable energy policy would be:

  • Support clean tech R&D;
  • Aggressively increase manufacturing capacity of clean energy;
  • Create a more favorable domestic market for clean energy;
  • Increase tax credits to bring the above goals to fruition.

The consensus of many of the experts of the conference seemed to be that our underachieving government was hardly the whole answer to the problem… but it could be doing a whole lot more.

To me, all this suggests two burning questions:

– Will our civic leaders ever emulate the intelligence, much less the creativity, of our clean tech scientists?

– And will today’s songwriters follow the example of the car-loving musicians of yesteryear and create hit songs about the new edible car? (Note: The title “Lola” is already taken.)

Britannia Still Rules… in Solar

President Obama has lately been busy advocating the comeback (after over thirty-five years!) of nuclear power plant construction, a policy wrongheaded in every respect – for our ecology, for our economy, even for our safety and that of our children and grandchildren. Instead of claiming to meet the climate change challenge by employing discredited “solutions” from the past, our cousins across the pond have, much more wisely, been looking to the future. The British government is doing what some mainland European governments (particularly Germany) are already doing and what governments everywhere should be doing: motivating people to use energy in a more sustainable way.

Following up on a policy it first made public in July 2009, the UK’s Department of Energy and Climate Change (DECC) recently announced the amounts of a new tariff, effective April 1, to help persuade their citizens to change their source of electricity from fossil fuels to renewables. This plan, called the Clean Energy Cashback, or the Feed-In Tariff (FIT), will provide families who invest in renewable energy systems – solar, wind, hydro or biomass – with a deal unprecedented in the UK’s history.

Not only would UK consumers be paid for any excess energy their homes contribute to the local grid, they would receive cash from the government for energy they use themselves. Participating households would receive a credit of 41.3 pence per kilowatt-hour (equivalent to about $.65), about four times the market value of the electricity, and would get a bonus 3 pence ($.05) for every kilowatt-hour exported back into the grid. In other words, householders can earn money as well as save it. The annual benefit in electricity savings would be equivalent to about $220 and the reward itself would come to about $1400. The amount would be adjusted over time for inflation. And it’s all tax-free, too.

Ed Miliband, the secretary of DECC, was quoted as saying, “The guarantee of getting an income, on top of saving on energy bills, will be an incentive to householders and communities wanting to make the move to low-carbon living.” One British family, the Colquhouns, spent the equivalent of $19,200 on their solar panel system and under the new policy, at a return of more than 8%, can expect to break even in less than 12 years. (The rate and duration of the tariff depends on the type of energy used and other factors.)

The policy is in line with the UK’s target of generating 15% of all energy from renewable sources by 2020. The government predicts that, by 2020, 2% of all electricity demand will be met by such small-scale renewable installations. The UK currently generates 5.5% of all its electricity from renewable sources, as opposed to 2% in the U.S.

The British public seems to have embraced the idea. According to one survey, 71% of UK homeowners said that they would think about installing a low-carbon system if they were paid enough. One of the side benefits of the situation is that some households that install renewable energy systems like solar may see the value of their homes rise: the houses themselves would generate energy income. Small-scale energy generators would also provide protection against rising fossil fuel prices. The construction industry is positively ecstatic: it is predicting a $42 billion dollar windfall (and lots of jobs) from new and retrofitted solar systems.

However, the policy has also met with considerable criticism on both the Right and the Left. Environmental groups object to it on the grounds that it doesn’t go far enough, because the tariff is too small. (The government claims that, since these incentives will be funded by a small annual extra charge to those who do not take part in the plan, it could not make the tariff higher because that would be unfair to non-participating households.) Dave Timms, of Friends of the Earth, was quoted as saying: “Ministers have been far too timid with a policy that could make a significant contribution to cutting emissions and boosting energy security.” Meanwhile, in a bizarre contrast to the situation in the United States, with its fanatical right-wing climate skeptics, UK Conservatives (“Tories”) have not only jumped on the FIT bandwagon, but have declared the policy “long overdue” and accused the current Labour government of “lacking ambition”!

Space Is the Place, Part I

In my youth, practically everything having to do with outer space conveyed a glamour that nothing else quite matched. Astronauts were to me near-mythic beings, more heroic than soldiers or cowboys. (John Wayne, after all, never had to cope with zero gravity.) Outer space was the place — more than any foreign country or remote area on earth — where nearly any possibility could be imagined. On TV and video, I devoured just about everything that had to do with space, from epic visions like 2001: A Space Odyssey to fables such as ET: The Extra-Terrestrial to the sleaziest sci-fi dreck… much as wholesome meals and sugary junk tasted much the same to my hungry and undiscriminating palate.

So there is a sense of satisfaction for me, after absorbing so much fantasy, in the idea that one of the greatest real-life wonders of space is its potential to help save humanity from our energy emergency through space-based solar power (SBSP). Something like the concept of SBSP has existed, at least in fiction, since 1941, when Isaac Asimov published the short story Reason, which is set on a spaceship from which energy is beamed by sentient (and highly temperamental) robots to distant planets. In 1968, the notion was promoted from science fiction speculation to science theory by Peter Glaser. Many people, including the Department of Defense, have recently been taking SBSP very seriously indeed. Everybody’s talking solar… but why is it so important?

SBSP, if and when it is successfully implemented, might well solve many of humanity’s energy problems. The sun is the most constant and dependable source of energy on earth. In what appears to be the “darkness” of space, there is, in fact, no night: solar panels could receive sunlight 24 hours a day, with no interference from the atmosphere nor any obstruction through bad weather. All this, of course, does not mean that space solar power will or should replace terrestrial solar power. But if and when it becomes viable, it might well become the main energy source for many on this planet.

Three basic elements are necessary for a viable SBSP system:

1. a way to transform, in space, the energy from the sun into electrical energy and collect that energy;

2. a way to transmit this collected energy from space to earth;

3. a way to receive on the earth’s surface the energy from space and distribute it to users.

The good news is that much of the technology necessary for making SBSP a reality not only exists, but is actually quite commonplace. Commercial space satellites — the machines necessary to carry out the first element above — have been in existence since Telstar, launched way back in 1962. Photovoltaic (PV) cells for harnessing solar energy are of course in increasingly common use. (Even the International Space Station employs solar arrays, though strictly for its own use.) As for the second element, both microwaves and lasers have been proposed as the means to convey solar energy from space to earth; both these technologies are well advanced. For the third element above, rectangular antennas (called “rectennas“) are the most commonly proposed method of catching the energy from space on earth.

So what’s holding us back?

The most significant problem seems to be one of scale… and here is revealed the “profitability paradox” at the heart of the SBSP project. Simply put, to produce the sheer quantity of electrical power necessary to make the program affordable would seem to require devices of colossal size and complexity, both in space and on the ground. But the fact that the devices need to be so large and complex makes creating and assembling them deeply problematical… and potentially unprofitable.

It has been estimated that an adequate receiving antenna in space (which would, of course, be only one part of the entire satellite) would need to be a kilometer (over six-tenths of a mile, or about 11 football fields long) in diameter — which is almost two miles in circumference and over three-tenths of a square mile in area. How to get such a Godzilla of a device into orbit — and keep it functioning once it’s there — may be the biggest single challenge of SBSP technology. And then there’s the rectenna, an enormous structure in its own right, estimated at perhaps 10 kilometers (6.2 miles) wide and 14 kilometers (8.7 miles) long… though at least no one has to lug the damn thing into space. (Note: the dimensions above represent one theoretical estimate; Solaren, the California-based corporation, envisions a satellite array several miles across, while the Japanese space agency, JAXA, proposes a receiving station on earth that would “only” be 1.8 miles wide.)

The Good, the Bad and the Irrational

Now that we’ve finally left behind that unmourned year, 2009, the Internet seems to have arrived at a consensus on two seemingly contradictory premises vis-a-vis solar power. These are: a) last year was a very rough year for the industry, and b) the outlook in general for solar in 2010 and beyond is fair to excellent. In other words, if the battle of the solar industry with the fossil fuel giants could be compared to a prizefight, the round just ended has left the challenger seriously battered, but still standing and primed to charge out of his corner swinging when the bell rings again.

Predictably, in the aftermath of the financial collapse, the cleantech sector suffered a decline by just about any measure: sales, profitability, stock prices, even venture capital. Even so, the statistics can deceive. Investment was actually up significantly in 2009 from just two years ago and solar, among all the renewables industries, is the undisputed leader, pulling in $1.4 billion from investors (the second biggest was biofuels), more than a quarter of the whole renewables market. Most sources are predicting a good year for solar in 2010, or at least the beginnings of a recovery.

Strangely enough, one of the main problems with solar in 2009, according to one blogger, has been oil… or rather, people’s quite illogical perception of it. Very little oil goes towards creating electricity, he noted. Yet when oil prices decline, so does the demand for solar. How can this be?

For Americans, there seems to be some kind of psychological block when it comes to investing in new tech, so long as those good ol’ familiar fossil fuels can be had at bargain prices. And, despite all warnings, Americans have never really bought into the idea of resource depletion (never mind global warming). They cling, like primitive peoples, to the atavistic myth that oil and gas, like diamonds, are forever, unwilling to grasp that renewables will, sooner or later, become absolutely necessary. Call it the Palinolithic Effect.

So even though solar advocates, despite the economy, are standing at the crossroads of a major breakthrough for human sustainability (and survival), here comes stubborn human irrationality — like Eli Wallach‘s sinister Mexican outlaw — blocking our path. Paging Clint Eastwood!
