Integrating Wind and Solar Energy: German Virtual Power Plant Shows How to Do It

German Combined Power PlantOver at ThomasNet Green & Clean today, I’ve written about a groundbreaking pilot project called the Combined Power Plant. See the article, “German Combined Power Plant Demonstrates Real-Time Integration of Renewables.”

What these scientists are doing is using networking technology to integrate 36 separate solar, wind, and biogas installations into one “virtual power plant.” Combining multiple sources like this allows them to balance out the various sources, solving a key problem in the integration of renewables into the electric grid.

Can The Economy Keep Growing Without Destroying the Planet?

Over at ThomasNet Green & Clean earlier this week, I explored the topic of “Decoupling” as it applies to economic growth and its connection to environmental damage and the depletion of resources — see “Decoupling: Can Humanity Prosper Without Plundering and Poisoning the Planet?

The write-up extracts the essence from a report by the United Nations Environmental Programme (UNEP). The authors lay out the basic argument and data for decoupling. The report’s authors believe that innovation is the answer:

Innovation now needs to be harnessed for resource productivity and environmental restoration… innovations that contribute to decoupling through reducing environmental pressure and contributing to sustainability during economic activities.

Are Speculative Bubbles Ever a Good Thing?

Over at Bubbleconomics, I wrote recently about the effect of speculative bubbles on innovation — see “Speculative Bubbles: Good for Innovation?

For a long time, I’ve thought that the so-called “Internet Bubble” from the 1990s was actually a good thing in many ways in that it sparked technology and business-model innovation and trained a generation in a new way of thinking about business and communication. Networking pioneer Bob Metcalfe agrees with me, as he says in a 2011 presentation:

We saw from the many Internet Era bubbles that investment, speculation, inflation, competition, and collapse are tools of innovators against the status quo. Bubbles accelerate technological innovation.

The Coming Energy Internet

Over at ThomasNet Green & Clean, I’ve posted “Is an ‘Energy Internet’ Emerging?” I’ve included some insights from networking pioneer Bob Metcalfe, also Thomas L. Friedman and Jeremy Rifkin, as well as my own thinking about the increasingly networked energy grid.

In an email conversation, Metcalfe acknowledged to me that “energy can be viewed as a thermodynamics problem or a government policy problem,” but he thinks that ultimately  “it’s best instead to view energy as a networking problem.”

In a presentation, he gives a bit of history:

“While building Internet 1.0, the Arpanet,” during the 1970s, Metcalfe says in his presentation, “I remember this clearly, we did not say that our goal was YouTube.” And yet, “video is most of what the Internet now carries.”

So, he asks,

What will be energy’s YouTubes?

Undo: One of the Greatest Innovations in Computing

The Undo function — a life-saver.

From “Behavioral issues in the use of interactive systems,” Lance A. Miller and John C. Thomas, International Journal of Man-Machine Studies, Sept. 1977:

A more complex situation, however, occurs … when a user wishes to “undo” the effects of some number of prior commands — as, for example, when a user inadvertently deletes all personal files. Recovery from such situations is handled by most systems by providing “back-up” copies of (all) users’ files, from which a user can get restored the personal files as they were some days previous. While this is perhaps acceptable for catastrophic errors, it would be quite useful to permit users to “take back” at least the immediately preceding command (by issuing some special “undo” command).

Now if they would only invent an Undo button for one’s personal life.

Chart shows how much radiation you would absorb from various sources

This chart from XKCD shows the ionizing radiation you might absorb from various sources according to the standard sievert (Sv) measurement unit.

The interesting thing about this chart is it allows you to compare radiation absorption of a wide range of activities from the smallest risk, sleeping next to another person (tiny risk); to something greater but not really that bad in the end, such as being 50 km away from the Fukushima site in Japan; to something catastrophic, like being next to the Chernobyl reactor core after its explosion and meltdown. The chart helps you to understand where a fatal radiation dose stands within that great range.

XKCD gives a disclaimer that the chart probably contains mistakes and warns that “if you’re basing radiation safety procedures on an internet PNG image and things go wrong, you have no one to blame but yourself.”

The following image is linked from the original — click on it to inspect the original at full size.

Gulf Disaster: Sparking an Explosion of Innovation in Oil Cleanup?

Sickening as it is, the unfolding oil disaster due to the runaway gusher in the Gulf of Mexico (the terms “leak” and “spill” hardly seem adequate) is giving rise to a flurry of innovations in oil cleanup that should result in more effective responses to such crises in the future.

Watching BP and the federal government flounder around these first several weeks of the disaster, many individuals, small businesses, and local officials in the Gulf region have stepped forward with cleanup solutions, some sophisticated and well-thought-out, some not so much (see “Battling oil with ‘Cajun ingenuity.’” But the point I’m making is that it’s interesting to see how a crisis like this is useful as a stimulus for innovation.

I’ve been able to dig up a few CNN reports that show examples.

Dragonfly floating triage center for cleaning oiled birdsI was particularly struck by a report just today about two boatmakers who have quickly generated a kind of floating “M*A*S*H” facility for cleaning up oiled birds. The unit is based on the design of shallow-draft fishing boats that can easily maneuver in coastal waters and marshlands. Birds can be picked up, cleaned, and released right from the boat, without the time-consuming process of taking them into land-based facilities. (See “Boatmakers: Oil officials ignoring bird-saving boats“)

As is often experienced by innovators within large companies and organizations, the two Alabama boatmakers, Mark Castlow and Jimbo Meador, have run into problems getting uptake of their innovation by the large bureaucratic entities running cleanup efforts.

CNN made calls to find out why the solution has not been exploited by BP and the government. The CNN journalist says that, “The unified command center admitted that juggling all the offers of help has been a problem.”

One of the boatmakers says, “It’s one of the most frustrating things I’ve ever been involved in.” So far, they have been able to produce a prototype boat with funds from private donors, including musician Jimmy Buffet. From here on out, they plan to produce a new boat every seven days.

When I heard that actor Kevin Costner was getting involved in cleanup efforts, my first reaction was, “Oh, ha-ha, he should get together with Brad Pitt and George Clooney, ha-ha!” But thanks again to CNN, I have learned that, in reality, Costner and his colleagues at their company, Ocean Therapy Solutions, are actually selling BP a cleanup device that he and his brother, a scientist, developed during the early 1990s.

Costner’s machine is a device for separating oil from water. His largest machine has about a 5′ x 5′ footprint, weighs about 4,000 pounds, and can separate 200 gallons of liquid a minute, separating oil and water at 99.9 percent purity on either side.

Costner brought the machine to market over a decade ago, but couldn’t raise any interest until the current crisis. “I guess people just thought spills were over,” he tells Anderson Cooper of CNN. But to the contrary, he says, “Spills occur on a daily basis. Someone said enough oil spills on a daily basis that every seven months we’re having an Exxon Valdez out there. It’s just, out-of-mind, out-of-sight. It takes something like this to happen, where now we’re all pointed at it.”

Costner took his product for years to government agencies and private industry with no success, but now BP has ordered 32 of the devices. Costner tells CNN, “I’ve had to be kind of silent the past few weeks as this machine was put through a lot of hoops, and it just passed everything that BP could throw at it.” (See Cooper’s video interview with Costner, “Kevin Costner’s solution to oil spill.” See also Ocean Therapy’s news release, “BP to Proceed With Costner Centrifuge Devices to Cleanup Gulf Oil Spill.”)

1947 Texas City Disaster and Its Effect on Industrial Safety

What should companies be doing to prevent disasters such as the ongoing catastrophe in the Gulf of Mexico, with its tragic loss of life and environmental devastation? Granted, some disasters are just ‘Black Swans’ (see Nassim Nicholas Taleb’s writings on this topic) and can’t be predicted. But company safety procedures can go a long way toward mitigating the risks of accidents and their potential effects.

Having served as a company safety officer and having written about industrial safety some years ago, I was very interested in the experience published today by Robert X. Cringely on his I, Cringely blog — see “Doing the Right Thing.”

Cringely republishes a comment from one of his readers, a Monsanto engineer, who recounts how Monsanto learned from the calamitous April 16, 1947, industrial accident at Texas City harbor. That accident was caused by a fire on a ship, not by Monsanto. However, the resulting explosion destroyed Monsanto’s plant, along with other facilities at the port and thousands of homes. Almost 600 people were killed. (See the Wikipedia article on the Texas City Disaster and the series of photos at the Portal to Texas History.) Here’s an aerial view of the Monsanto plant and the port after the accident:

As a result of Texas City, Monsanto developed a stronger culture of safety, says Cringely’s reader:

They developed technology to better control chemical process. They developed standards to built safer facilities. They didn’t do this alone. They worked closely with other chemical companies. The whole industry invested in best practices and shared what they learned. When I started my job [in the 1970s] I was given a set of “standards” consisting of 3 binders, each 6 inches thick — serious reading.

Union Carbide’s terrible accident in Bhobal, India, in 1984 also became a crucial lesson for industry players. Soon after Bhopal, Monsanto officials had “reverse-engineered” the disaster and reiterated company policy, emphasizing that “all plants are to be built to USA or local country safety standards, whichever is better.”

Further studies within Monsanto after Bhopal had a profound effect on the company’s business:

The result of the study was sweeping changes in how much material was stored in each facility. Many processes and lines of business were deemed too risky to continue and were shut down. Monsanto walked away from tens of millions in business to reduce risk and improve safety.

Monsanto also instituted new programs to train and equip local first-responders where its plants are and to reduce emissions “far exceeding EPA rules.”

These comments emphasize the value of adopting the stance of a “learning organization.” What kinds of company policies and practices can go the furthest in preventing accidents, loss of life, and environmental damage — and in minimizing the effects when accidents do occur?

One Reason Youtube Is a Great Resource: Khan Academy’s 1,200 Educational Videos

Many people think of YouTube as a big time-waster with nothing but videos of animals dancing and guys getting whacked in their privates.

But as time goes on, I become more and more conscious YouTube as a great resource in many respects. For example, in my work as a writer and analyst, I’ve been making good use of corporate videos on YouTube, where it’s possible now to access in-depth presentations by company executives, scientists, and other experts.

Thanks to a mention yesterday in Boing Boing, I’ve learned about Khan Academy, which now has over 1,200 educational videos on YouTube. Using a very simple “chalk talk” format, Salman Khan, an engineer and manager, provides 10-20-minute video presentations on a huge variety of topics, including science, history, math, finance, economics, and more.

These videos would be useful as quick reviews or knowledge fill-ins for students, both adult and child, or for parents who are trying to help their kids with their studies. I also find them useful as a writer who needs to be able to get up-to-speed quickly on economics and finance topics.

Khan creates his videos on a tablet computer with pen input. Here’s an example of a video explaining the basics of banking:
