I believe that #thermonuclear fusion may be the #future, but in all this type of #research, #energy balance does not take into account the energy consumed to obtain the right conditions in which the fusion can take place... So writing about a positive balance completely misses the truth.

Online book talk tomorrow from University of #Oslo:

In the fall of 1961, President Kennedy somberly warned Americans about deadly radioactive fallout clouds extending hundreds of miles from H‑bomb detonations, yet he approved ninety‑six US nuclear weapon tests for 1962. Since the #nuclear attacks on #Hiroshima & #Nagasaki there have been over 2,000 nuclear tests; we envision the Cold War as a period in which nuclear weapons were not used when in fact statistically there was a nuclear detonation every 8.6 days between 1950-1989. Millions of people lived downwind from those nuclear tests, and #thermonuclear tests raised radioactive fallout into the troposphere and stratosphere which eventuated in global distribution of radionuclides. Millions more lived near nuclear production sites, or accident sites like #Chernobyl and #Fukushima. These are the “global #hibakusha.”

#ITER -International #Thermonuclear Experimental Reactor- being built in #Cadarache (#Marseille,#France) is also based on #Tokamak
and it will cost EUR 24,000 million - it is 5th most expensive project in history of Humanity-
After construction it was determined that objective of ITER would not be to produce energy but would have zero power: produce same one that it consumed
Also indicate that energy is released in 7 min.for every 30 min. of operation:
it is pulsed, so not commercially useful

Of all #Infinity, #We can #Live only within a couple vertical #Miles of #Flammable and #Oxidizing #Atmosphere on a rather average-sized #Planet spinning at 1000 mph while #Orbiting a naturally formed 4.6 billion-year-old #Thermonuclear #Hydrogen #FusionReactor at a speed of 66,000 mph which, from a #Distance of roughly 93 million miles, happens to be able to #Supply us with nearly all the #Energy needed to #Us.

Today in Labor History February 5, 1958: The U.S. Air Force lost a Mark 15 thermonuclear bomb in the water near Tybee Island, near Savannah, Georgia. The B-47 bomber was on a simulated combat mission. It collided with an F-86 fighter plane, midair, and jettisoned the bomb in order to make an emergency landing without detonating it. Sources vary on whether it was a “dummy” bomb, or if it had a plutonium core. If it was a “dummy” bomb, it still carried 400 lbs of conventional high explosives, enough to do considerable local damage. However, Assistant Secretary of Defense W.J. Howard, told Congress that the Tybee Island bomb was a "complete weapon, a bomb with a nuclear capsule" and one of two weapons lost that contained a plutonium trigger.

For a truly terrifying history of the history of nuclear weapons systems and accidents involving nuclear weapons in the United States, read Eric Schlosser’s “Command and Control.”

Today in Labor History January 31, 1950: President Truman ordered the development of thermonuclear weapons (Hydrogen bombs). The U.S. tested the first thermonuclear weapon in 1952. It was developed by Edward Teller. H-bombs consist of a nuclear fission primary stage, much like older atomic bombs. The fuel for this stage is usually 235U or 239Pu. This is followed by a nuclear fusion reaction using the heavy hydrogen isotope deuterium and tritium. Modern thermonuclear weapons use lithium deuteride. The nuclear fission stage creates a temperature of over 100 million Kelvin (180 million degrees Fahrenheit), flooding the radiation channel with X-rays. The X-ray energy implodes a plutonium spark plug, compressing the secondary stage and driving the plutonium into a supercritical state that drives a fission chain reaction. The fission products heat the thermonuclear fuel to 300 million Kelvin, igniting the fusion reactions.

The One Thing Everyone’s Ignoring About the Fusion Energy Breakthrough

“Our #thermonuclear weapons have fusion ignition that takes place in our weapons, so studying fusion ignition is something we do to support the stockpile stewardship program,” Mark Herrmann, Lawrence Livermore’s program director for weapon physics and design. “In addition, fusion ignition creates these very extreme environments that we have no other way to access on Earth. In this experiment, for the first time ever, we were able to put some samples of materials that are important for future stockpile modernization efforts”

“Fusion is an essential process in modern #nuclear weapons, and #fusion also has the potential for abundant clean energy,” said Marvin Adams, “As you have heard, the breakthrough at NIF has ramifications for clean energy. More immediately, this achievement will advance our national security in at least three ways.”

I worry about war between the US and another major power more than I worry about #ClimateChange . Even if it doesn't go #thermonuclear , there's a lot that could go wrong.
