Can nanotechnology and biotechnology help cities go green?

Friday, October 26th, 2007

For example, Tim Method, Environmental Coordinator for Indy’s Department of Public works, explained that half of the city’s energy expenditures are for sewage treatment. And when we get a good rain, which happens about fifty times a year, raw sewage overflows into our creeks and rivers. Fortunately, the city plans to spend almost $2 billion over the next twenty years to fix that problem.

But what can emerging technologies like nanotechnology and biotechnology do to help green our cities? Nanotechnology is advancing water treatment significantly, and one Australian city is even using methane from wastewater to power a treatment plant. Advances in nano-solar cell technology could also enhance programs like Indianapolis Power and Light’s Green Power Option, which allows customers to specify an amount up to 100 percent of their monthly electricity to be generated by environmentally friendly, renewable resources.

I’m looking forward to helping make Indy GreenPrints a reality and introducing environmentally friendly and energy-saving nanotechnologies and biotechnologies where appropriate.

Nanotechnology could have prevented Minneapolis bridge collapse

Monday, August 6th, 2007

minneapolis_bridge_collapse.jpgAs inspectors sift through the debris of the Minneapolis Interstate 35 bridge collapse, I can’t help but think how nanotechnology could have prevented the tragedy. If a network of nanosensors or microsensors like the ones currently in place on the Golden Gate Bridge had been in place on the Minneapolis bridge, they might have warned of impending failure. Microsensors in place on the Golden Gate Bridge give a real-time, comprehensive picture of the bridge’s performance. They can measure stresses at any point along the structure along with their potential impact on the rest of the bridge.

Nanosensors and microsensors combine low manufacturing costs, compact size, low weight and power consumption, as well as increasing intelligence and multi-functionality. Their market is predicted to grow from $36 billion to $52 billion in 2009. I wouldn’t be surprised to see it grow even faster as engineers look for new ways to prevent disasters like the Minneapolis bridge collapse.

A critical step: design science and the Ilulissat statement

Sunday, July 1st, 2007

ilulissat_thumb.gif“Are you spontaneously enthusiastic about everyone having everything you can have?” That’s the question posed by R. Buckminster Fuller in Critical Path. Like most people, I would answer with a hearty “yes”. But like most “haves”, I get a little nervous if it looks like providing for others is going to cost me some of my comforts. When that happens, I remind myself that more for today’s “have-nots” doesn’t have to mean less for me.

Rather than taking from the haves and giving to the have-nots, we can achieve equality by making more efficient use of the resources we already have. Our earth and sun provide us with all the resources we need for all of us to live well, if only we are willing and able to steward them properly.

As Fuller observed, “. . . humanity now—for the first time in history—has the realistic opportunity to help evolution do what it is inexorably intent on doing—converting all humanity into one harmonious world family and making that family sustainingly, economically successful.”

I often wonder if nanotechnology and biotechnology could be the keys that open a new world so rich in wisely utilized resources that we can all live well. And apparently, I’m not alone. The week of June 11, 2007, thirteen of the world’s leading scientists gathered in Ilulissat, Greenland for the Kavli Futures Symposium, “The Merging of Bio and Nano: Towards Cyborg Cells.” They felt so strongly that nano and bio will have such a profound effect on humanity that they issued a statement unanimously stating their position in The Ilulissat Statement, “Synthesizing the Future: a Vision for the Convergence of Synthetic Biology and Nanotechnology.” Among their conclusions:

“The construction of arbitrary genetic sequences comparable to the genome size of simple organisms is now possible. Turning these artificial genomes into functioning single-cell factories is probably only a matter of time. On the hardware side of synthetic biology, the train is leaving the station. All we need to do is stoke the engine (by supporting foundational research in synthetic biology technology) and tell the train where to go.”

So, all we need to do is tell the nano-bio train where to go! They make it sound so easy! But many people believe that the tracks these technologies must follow have already been laid, their direction already determined by political or corporate interests.

Bucky Fuller was not one of these people. He believed the critical path technology and humanity will follow will be determined, not by politicians or corporations, but by individuals working together to create a critical mass powerful enough to direct and, as necessary, redirect the train. The discipline required to steer it? Not political or financial clout, but “the design science revolution.”

In other words, technology itself isn’t enough. It must be guided by design principles. The Ilulissat Statement is very much in harmony with ecological design principles, as are Fuller’s principles. That’s the vision of Green Technology Forum as well, to encourage the use of ecological design principles in the application of nanotechnology and biotechnology. It’s a strategy that can benefit business and consumers, and can help us build the kind of world envisioned by luminaries like Fuller and the Ilulissat group.

Nanotechnology and green technology converge at Cleantech 2007

Thursday, May 24th, 2007

santa_clara.jpgThis week I’m in Santa Clara, California for the joint Nano Science and Technology Institute and Cleantech 2007 conferences. Collocating the conferences was a great idea, generating a wealth of discussion and ideas on nanotech applications for green technology. I gave a talk on nanotech for green building, and hundreds of other oral and poster presentations covered everything from energy to transportation and new materials.

By my estimate, this year’s conference drew even more attendees than last year’s, which topped 4,000. The ever-present Vinod Khosla spoke of technologies for replacing oil and coal as “the only green technologies that matter,” and said that new green technologies must pass “The Chindia Test,” meaning that to make a difference they must be affordable in the Chinese and Indian markets.

In another keynote, Lawrence Dubios, vice president at SRI International, struck a similar theme, saying that in order for new green technologies to succeed they must be “painkillers and not just vitamins.” Watch for nanotech advances in solar technologies, he said, noting that the cost of silicon (the primary material in conventional solar cells) has doubled in the past year.

While I was there, Matt Laudon, TechConnect executive director and organizer of the conference, invited me along with seven other green tech experts to form the first Cleantech organizing committee. We’re looking for ideas for Cleantech 2008, to be held in Boston at the end of May, so if you have any ideas please leave a comment.

Venture capital takes center stage at World Congress on Industrial Biotechnology

Monday, March 26th, 2007

disney_swan_dolphin_resort_2.jpgLast week I took part in the World Congress on Industrial Biotechnology and Bioprocessing, a powerhouse event in Orlando, Florida, that brought together industry leaders, venture capitalists, and academics for an intensive discussion of current and future trends in industrial biotech.

Biofuels were of course the hot topic, and experts were enthusiastic about future developments in that area. Vinod Khosla of Khosla Ventures speculated that cellulosic biofuel could be cost-competitive with corn by 2009. Dr. Jens Riese of McKinsey & Co., who shared the podium with Khosla during a plenary lunch, said he expects we won’t see that until about 2012, depending on the cost and availability of feedstocks. Reise also observed that it’s farmland economics and fuel security that are the big biofuel drivers in US, whereas in Europe it’s the environment.

Among the many insights into biotech venture spending was Andrey Zarur of Kodiak Venture Partners, spelling out exactly what venture capitalists are currently looking for in biotech:

Small-scale wind power

Point production of energy (distribution costs of centralized energy are too high)

Energy storage

Insulation

Auxiliary systems that integrate any of these
