Randy Sarafan/Instructables.com: chalkboard table

by jonathansoroko on March 4, 2010

Randy Sarafan defies easy description. He's clearly a polymath of some sort, a provocateur of more than one sort, and a cannon (perhaps loose perhaps not) on the deck of technology. Even a quick look at his work makes it clear that his excellent contributions to "appropriate technology" don't preclude the occasional foray into inappropriate technology. He's also the author of the funniest collection of unanswered1 correspondence since The Laszlo Letters2.

Mr. Sarafan has posted a recipe for a simple chalkboard-surfaced table on the outstanding  and ever-useful Instructables.com.

Chalkboard Table design by Randy Sarafan

While Sarafan's design assumes Ikea trestles, this can be managed with sawhorses, or leaned against or mounted on a wall.The only indispensable items are chalkboard paint, a relatively smooth surface (Sarafan's table was made of MDF) and chalk.

The point is that, with inexpensive, easily available materials, it's possible to create a graphic representation of, for instance, a neighborhood - for planning purposes - or even in the midst of a crisis. While rolls of butcher paper are also available quickly, they're not easily erased as revisions and updates are required. There are, of course, more sophisticated variations: magnetic white boards permit the use of objects and markers (for streets, vehicles, people); acetate overlays over maps permit drawing with grease pencils; GIS applications permit much more nuanced data manipulation.

But this will work- and can be seen and worked on by more than one person at once - without electricity, without much more than a smooth surface, chalkboard paint, and chalk.

We'll try to post some other variations on simple "sand-table" solutions in the near future.

Vermont Senate Voted to Shut Down Vermont Yankee

by L J Furman on February 27, 2010

Vermont Yankee, on the Connecticut River

Vermont Yankee, on the Connecticut River

The Vermont Senate voted 26 to 4 to close Vermont Yankee.  While proponents of nuclear power claim that the plants can be run safely and economically, Entergy, the Louisiana company that operates the plant, is now known to be running Vermont Yankee AT A LOSS! Economics is not the issue. The Vermont Senate isn't interested in the profitability of an enterprise. What is at issue is whether Vermont Yankee can be operated safely and whether Entergy can be trusted to operate Vermont Yankee safely. By a vote of 26 to 4, the Vermont Senate answered those questions with a resounding "NO!"

An Entergy Executive responsible for Vermont Yankee testified under oath to two state panels that there were no buried pipes at Vermont Yankee that could leak tritium.  This testimony is now known to be false. The Entergy executive has been relieved of his responsibilities. (Click  here.)  According to NPR (here) "Entergy Nuclear chief executive J. Wayne Leonard did not identify the official by name. But he described the executive relieved of his duties in a way that could only apply to Vice President Jay Thayer.

State Senator Peter Shumlin, Democrat, Wyndham, asked "What's worse, a company that won't tell you the truth or a company's that's operating your aging nuclear power plant on the banks of the Connecticut River and doesn't know that they have pipes with radioactive water running through them that are leaking? And they don't know because they didn't know the pipes existed. Neither is very comforting."

Vermont State Senator Randolph Brock, Republican, St. Albans, who in the past has supported Vermont Yankee, said “If the board of directors and management of Entergy were thoroughly infiltrated by antinuclear activists, I do not think they could have done a better job of destroying their own case.”

Entergy claims that no tritium has turned up in drinking water, but that claim must be verified. The Connecticut River, which flows past Vermont Yankee, probably should be checked for Tritium.

Officials at Entergy, the Louisiana company that owns Vermont Yankee, are trying to sell Vermont Yankee, Indian Point, and three other nuclear power stations in the north-east.

It is a similar design to the Oyster Creek nuclear power station, in New Jersey, operated by Exelon, which is also known to be leaking tritium.

Mercury and Orcas

by L J Furman on February 27, 2010

An orca in the open ocean

Tilikum, an Orca, attacked and killed Dawn Brancheau, a trainer at Seaworld, Orlando, on Wednesday, Feb. 24, 2010.

As reported in Asia One, Ric O'Barry and Dave Phillips of the Earth Island Institute have called for a federal investigation into the death of Ms. Brancheau.

In their statement, O'Barry and Phillips said,

"SeaWorld allowed public and trainer contact with an orca that was a known risk, and after three deaths they're suggesting that it actually continue.... We believe this situation warrants the immediate initiation of a federal investigation into SeaWorld's possible negligence and violations of the Marine Mammal Protection Act....Along with sadness of this tragic event we can't help feeling anger toward those who insist upon exhibiting these wild creatures in habitats that can drive them to violence."

Let's look at this from another side.

  • Orcas eat fish, as do other whales, dolphins, and humans.
  • Fish are high in mercury. (All mercury pollution comes from human industrial activities, much of it from burning coal in power plants).
  • Mercury causes brain damage.

This leads to a few questions:

  1. What is the level of mercury in the Tilikum's brain and central nervous system?
  2. Is it causing nervous system damage?
  3. Is  Tilikum "Mad as a Hatter?" Is he suffering from Minamata's Disease?

The Kyoto Box, a solar cooker which retails for €15 (about $20 USD) can boil 10 liters (2.64 gallons) of water in 2 hours. So apart from its primary uses - cooking and water purification - it can probably be pressed into service to sterilize medical instruments.

The manufacturer, Kyoto-Energy, has offices in Indonesia, South Africa, and headquarters in Kenya, which suggests local production.

According to the WHO, 1.6 million people die worldwide annually from gases produced by indoor cooking. 1

The Kyoto Box, then, has a number of virtues:

  • no scale requirements; because they're entirely autonomous, one or one million in use will have an effect;
  • reduction of indoor air pollution deaths; and used in scale, a reduction in outdoor air pollution as well;
  • reduction of water-borne diseases via water purification, and food-borne diseases via cooking;
  • lowering of energy costs;
  • where wood is used for fuel, a reduction of deforestation, with the long-term effects of mitigating flood risk and increasing the availability of lumber and tree shade

  1. More than half of the world’s population rely on dung, wood, crop waste or coal to meet their most basic energy needs. Cooking and heating with such solid fuels on open fires or stoves without chimneys leads to indoor air pollution. This indoor smoke contains a range of health-damaging pollutants including small soot or dust particles that are able to penetrate deep into the lungs. In poorly ventilated dwellings, indoor smoke can exceed acceptable levels for small particles in outdoor air 100-fold. Exposure is particularly high among women and children, who spend the most time near the domestic hearth. Every year, indoor air pollution is responsible for the death of 1.6 million people - that's one death every 20 seconds.  Source: WHO Fact Sheet, "Indoor Air Pollution and Health, " dated June 2005.

Tiger Woods & Subprime Mortgages

by L J Furman on February 26, 2010

Tiger Woods may be a great golfer. But I wouldn't buy a mortgage from him. Here's why.

(click to stream audio)

Economics II: Macroeconomics and Political Economy

The way for the government to stimulate the economy and to avoid or climb out of a Depression, as John Maynard Keynes wrote, and as President Franklin Delano Roosevelt proved with the New Deal, is to invest money and resources in infrastructure, not to lower taxes or put money in the hands of private businesses. This latter tactic, which New Jersey's new Governor, Chris Christie1 is trying, was not proven to work by President Herbert Hoover and proven not to work by President George W. Bush.

Keynes' basic analysis rests on two evident economic phenomena. One is the different effects on the Keynsian Multiplier of government revenues collected as taxes and government revenues not collected as tax-cuts. The other is the basic response of people to a “Deep Recession” or a Depression.2

If a Recession is a series of calendar quarters in which there is a decline in GDP, a “Deep Recession3” or a Depression is characterized by a recession in which there is a general reluctance to invest in new staff or new projects on the part of businesses and individuals. A portion of any income, tax refund, or tax cut is saved. Money is hoarded. Money spent by the government is obviously, spent. The Keynsian Multiplier of money spent directly by the government is greater than money provided to businesses by tax credits because the government spends money directly, while individuals and businesses spend what they must and hoard what they can. For example, for every $1 Million the government spends purchasing goods and services, $1 Million is added to the GDP. However, for every $1 Million of taxes the government cuts, there is $1 Million the government doesn't spend, a chunk of that $1 Million is spent, and a chunk that $1 Million is hoarded.4 When the government spends directly, particularly on domestic infrastructure, the Multiplier is, in a word, multiplied.

Obama's tax incentive to hire people, is partially neo-classical, supply-side economics of the type favored and proven ineffective by Hoover and Bush. However, to the extent that it generates jobs, it will help the people whos jobs are created, their families, and the economy.

Robert Reich, a Keynesian economist, said5,:

“The best and fastest way for government to prime the pump is to help states and locales, which are now doing the opposite. They're laying off teachers, police officers, social workers, health care workers, and many more who provide vital public services. And they're increasing taxes and fees. ... We need a second stimulus directed at states and locales. “

Paul Krugman6 seems to agree. The only way to avoid a Depression is for the government to spend money. Lowering taxes doesn't work when people are reluctant to spend. However, the government must create jobs that will reduce the deficit in the future.

Wars don't do this. As President Bush demonstrated, wars create jobs that increase the deficit and deplete the economy by destroying capital, both human and physical. Investing in local clean, sustainable energy and rearchitecting the health care system in the United States, however, are ways to use government spending today to reduce future deficits.

Local Clean Sustainable Energy

Suppose we were to install a 50 kw photovoltaic solar array and a 2,500 liter (660.4 gallon) solar hot water heater system on every school in the United States. That's approximately 100,000 of each.7 Suppose each solar electric system costs $7.50 per watt, or $375,000, and each solar hot water heater would cost $50,000. That's $425,000 per school, at 100,000 schools that's $42.5 Billion. .

Because these are powered by a natural process – sunlight – rather than non-renewable fuels, and because of relatively low maintenance costs and operating costs, these systems will pay for themselves quickly and last a very long time, they will pay for themselves over and over. The return on investment is between 10% and 16% for PV Solar and 20% to 33% for Solar Hot Water. This is outlined in Table 1, below.

The ROI is higher when you factor in the external benefits of clean, renewable energy – there is no pollution, and therefore are no health effects from pollution.

One way to use the deficit to stimulate the economy in a manner that is consistent with reduced long term deficits is thru the development of clean energy resources, such as solar electric and hot water systems on the nation's public schools.

Health Care

In July, 2007, President George W. Bush said “People have access to health care in America. After all, you just go to an emergency room.8” While Emergency Rooms are well suited for acute conditions – emergencies – such as the traumas of car accidents, gunshot wounds, and broken arms, they are ill-equipped for chronic conditions such as hypertension, diabetes, cancer. If a person with diabetes was to go to the emergency room, the emergency room staff would say “We can't help you. Come back when you're in a coma, or you need your leg amputated.” Similarly, while the Emergency Room can't manage hypertension, it can treat the heart attack or stroke suffered by a person with hypertension.

Assuming Pres. Bush's statement is accurate, then the approximately 47 million, or one out of six, or 15.46% of Americans who don't have health insurance only have access to health care in an emergency. This means that the Health Care System can handle non-emergency health care for five out of six Americans, but is not capable of meeting the non-emergency needs of one out of six, or 15.46% of Americans. This means we need about 15.46% more doctors, nurses, medical office staff, hospital staff, medical offices, and hospitals. For every 100 medical doctors practicing today, we need 115.46. For every 100 nurses, we need 115.46.

According to the Bureau of Labor Statistics, there were about 661,000 physicians and surgeons in the US in 2008 and are about 2.6 million Registered Nurses, RN's, today.9 If this is sufficient for the 357 Million Americans who have health insurance, then we need an addtional 102,191 physicians and surgeons, and an additonal 401,960 nurses, and they need offices, examining rooms and other infrastructure. However, we can't just push a button and create 102,191 physicians and surgeons and 401,960 nurses out of thin air. It takes nine years to train a physician and three years to train a nurse.10

Paul Krugman on Banking, Securitization, and The Canadian Model

In his recent columns in the New York Times, Paul Krugman11 has discussed the banking industry, the banking debacle, banking reform, and the Canadian model for banking regulation and banking risk management. He quotes testimony by Jamie Dimon of JP Morgan Chase and Lloyd Blankfein of Goldman Sachs. In hearings of the Financial Crisis Inquiry Commission, Dimon basically said “this was business as usual.” Blankfein, however, said “it was an act of God.” While they disagreed about the cause of what happened, they agree with the solution: “Let bankers be bankers. If the government regulates banking, the economy will crumble.” It appears that we tried this deregulatory approach, and the economy crumbled.

“Securitization” of loans, in which bad loans are bundled with good loans and sold, doesn't limit risk, it rewards risk. In terms Tiger Woods or a Wall Street banker should be able to understand, Securitization is like sexual activity and HIV AIDS. Suppose one person has 100 relations with 10 partners, 10 with each, one of whom is infected with the HIV AIDS virus. Suppose another person has one relation with each of 100 partners, one of whom is infected with the virus that causes HIV AIDS. Clearly the first person has a higher risk of infection. However, the second person is also at risk. In the case of securitization of “toxic assets” the bankers were rewarded to have relations with as many people as possible. They didn't minimize risk. They spread it around.

The Canadian banking model limits risky loans, limits bank leverage, and limits securitization. This is what Obama must do. He must demand and enforce regulations that require transparency in banking, regulate derivatives, eliminate incentives for bankers to make bad loans, create incentives for bankers to make good loans; to practice what might be called safe banking. Regulations, for example, like those mandated by Glass Steagal.

Patrick Henry once said. “Give me liberty or give me death,”

Today he might add, “Entrust my money with cautious bankers.
