Tweet I am presenting “Beyond Fuel: From Consuming Natural Resources to Harnessing Natural Processes,” a discussion of the hidden costs, or “economic externalities,” of nuclear power, coal, and oil, and the non-obvious benefits of wind, solar, marine hydro and efficiency at the Space Coast Green Living Festival, Cocoa Beach, Florida, Sept 17, 2011. The festival [...]

Tweet It sounds too good to be true: * 100 gigawatts of offshore wind, $300 Billion, * 100 gw of landbased wind, $200 Billion, * 75 gw of solar, $300 Billion, * 75 gw of geothermal, $200 Billion. * 200 gigawatt equivalents of efficiency – $200 Billion. * 100 & Clean, Renewable, Sustaianble [...]

Tweet On Ayn Rand, Objectivism, and Climate Change Ayn Rand would not “believe” in climate change. She would try to objectively determine whether the theory correctly modeled the data. While it is legitimate to question both the conclusions of scientists and the methodologies by which data are gathered, denying objective validity of the data, which [...]

Tweet On May 25, 1961 President John Kennedy said, “I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the moon and returning him safely to the earth.” (Kennedy library and NASA) Ten years ago, before Sept. 11, Jim Gordon and his team [...]

Asking a nuclear engineering professor “Is radiation bad?” is like asking Charlie Sheen “Is cocaine bad?” Wind and water turbines, geothermal systems, and photovoltaic solar modules produce power without burning fuel. While there are resource footprints in the manufacture, installation, and maintenance of these facilities, there are no mines, no wells, no wastes to manage in their ongoing operation. Shouldn’t we be asking “How do we get utility scale base load power from wind and sun?” Shouldn’t we be figuring out “How to shift from a fuel-based energy paradigm to a sustainable paradigm?”

After Fukushima, the question is not: “Can we meet our needs with renewable, sustainable energy systems?” but rather it is “How can we meet our needs with renewable, sustainable energy systems?”

How Loud Is A Wind Turbine? Our friends at Treehugger re-published this graphic from GE, which builds wind turbines. If you’re standing next to a utility scale wind turbine, then you’ll hear it. At 300 meters, which is as close to residences as we can build them, they are about as loud as a refrigerator. [...]

Strange and counter-intuitive as it may seem, burning coal produces more radioactive waste than nuclear fission. And it’s not regulated. Back in 1993, Alex Gabbard, of the Oak Ridge National Laboratory, published “Coal Combustion: Nuclear Resource or Danger” in ORNL Review. Gabbard built on the work of J. P. McBride, R. E. Moore, J. P. [...]

Second in a series (1, 2) that began on “Earth Day” (0). “In order to make Policy, you have to be good at Politics.” – Deborah Stone, “Policy Paradox” I like and respect President Obama. I think he’s a well educated lawyer and law school professor, with a good grasp of the Constitution, and the [...]

The unfolding disaster at the Deepwater Horizon rig in the Gulf of Mexico, which promises to be an environmental catastrophe, (click here) the recent disasters at the Upper Big Branch coal mine in West Virginia, and the Kingston, Tennessee fly ash retention pond demonstrate that fossil fuels are dirty and dangerous. Safety and environmental protection [...]

Monday, April 4, 2010, in West Virginia, at least 25 coal miners were killed and another four remain unaccounted for in a methane gas explosion in a coal mine owned by Massey Energy. As reported in the NY Times, “In the past two months, miners had been evacuated three times from the Upper Big Branch [...]

Abstract. By burning fossil fuels we have put 3.6 trillion tons of Carbon Dioxide, CO2 in the atmosphere1 in the last 200 years – most in the last 60. This has changed the concentration of atmospheric CO2 from 270 parts per Million, ppm, to 390 ppm, an increase of approximately 31%. This increase of atmospheric [...]

The same messages can be communicated by signalling the letter "K" in Morse code via signal lamp. (While a proper signal lamp may be ideal, a flashlight, probably best employing red LEDs, will certainly fit the bill).
In Morse, the letter "K" is represent as Dash - Dot -- Dash.
The ICS also has a subset, the Medical Signal Code, which uses three-character phrases to communicate brief medical messages.
