ENERGY OF THE FUTURE

How It Works


Fusion occurs when the nuclei of two atoms join together to become one. The results: energy, a heavier nucleus, and a free nucleon. A nucleon is an elementary particle that can exist in either a neutral (as a neutron) or a positively charged (as a proton) state.

Researchers have found that the most useful elements for fusion are the hydrogen isotopes deuterium (one proton and one neutron) and tritium (one proton and two neutrons).


Fusion Reactors: Magnetic Confinement
Tokamak
“Tokamak” is a Russian acronym for “toroidal chamber with axial magnetic field.”

“There are two ways to achieve the temperatures and pressures necessary for hydrogen fusion to take place:

Magnetic confinement uses magnetic and electric fields to heat and squeeze the hydrogen plasma. The ITER project in France is using this method.

Inertial confinement uses laser beams or ion beams to squeeze and heat the hydrogen plasma. Scientists are studying this experimental approach at the National Ignition Facility of Lawrence Livermore Laboratory in the United States.
Let’s look at magnetic confinement first. Here’s how it would work:

Microwaves, electricity and neutral particle beams from accelerators heat a stream of hydrogen gas. This heating turns the gas into plasma. This plasma gets squeezed by super-conducting magnets, thereby allowing fusion to occur. The most efficient shape for the magnetically confined plasma is a donut shape (toroid).”

Advantages

Fusion creates a lot of energy, a huge benefit in a world increasingly demanding more power to operate both low-tech and high-tech machines.

The product of fusion is helium gas, which is not radioactive. This means that there are no radioactive wastes to store, or wastes that can be used to make weapons. There may be some very short-term radioactivity as the fusion products react with the container walls, but any fusion power plant would be designed to meet safety standards. Researchers believe that a decommissioned plant, one that no longer operates, would remain radioactive for 50 to 100 years. This is a much shorter period of time than for nuclear fission reactors.

Unlike nuclear fission, fusion reactions cannot run out of control. Any unusual event in a fusion reaction causes the plasma to extinguish itself.

HOW WOULD A MELTDOWN HAPPEN?

Turning to developments in Japan, where smoke is rising yet again at the crippled Fukushima nuclear power plant.

Aerial pictures of the quake-stricken Fukushima Dai-ichi nuclear power plant shot last Wednesday revealed the full extent of the damage of at least two of its troubled reactors: Units 3 and 4.

Workers have been trying to get power back to restore the cooling systems after last Friday’s powerful earthquake. They have now been evacuated from the area amid fresh concerns of a radiation leak and a potential nuclear metldown.

PRESS REVIEW – March 17, 2011
The Associated Press
LOS ANGELES — The U.S. government and scientists insist that there’s no threat of radiation from Japan endangering people on the West Coast — but that hasn’t stopped roughly 1,000 worried Californians from flooding a state hotline.

Sir John Beddington Top British Scientist Reviews Risks

Access the transcript of the conversation with the Chief Scientific Officer with David Fitton at the British Embassy in Tokyo on 15 March. Sir John Rex Beddington, CMG, FRS is the Chief Scientific Adviser to the UK Government and Professor of Applied Population Biology at Imperial College London, (March 15, 2011 update).

A few words about his view of what’s happening:

“It’s serious again for the local area. It’s not serious for elsewhere even if you get a combination of that explosion it would only have nuclear material going in to the air up to about 500 metres. If you then couple that with the worst possible weather situation i.e. prevailing weather taking radioactive material in the direction of Greater Tokyo and you had maybe rainfall which would bring the radioactive material down do we have a problem? The answer is unequivocally no. Absolutely no issue. The problems are within 30 km of the reactor.

And to give you a flavour for that, when Chernobyl had a massive fire at the graphite core, material was going up not just 500 metres but to 30,000 feet. It was lasting not for the odd hour or so but lasted months, and that was putting nuclear radioactive material up into the upper atmosphere for a very long period of time.”

“The problems with Chernobyl were people were continuing to drink the water, continuing to eat vegetables and so on and that was where the problems came from.

That’s not going to be the case here.”

Review of Japanese Nuclear Meltdown & Jet Stream Map

 


Officials insisted that unless the quake-damaged nuclear plants deteriorated into full meltdown, any radiation that reached the United States would be too weak to do any harm. Washington had “hypothetical plots” for worst-case plume dispersal within hours of the start of the crisis, a senior official said Sunday. The aim, the official added, was “more to help Japan” than the United States, since few experts foresaw high levels of radiation reaching the West Coast.” (Energy Department officials, speaking on the condition of anonymity)

The Future After the 2008 – 2009 Crash

March 2009 The Atlantic

How the Crash Will Reshape America

The crash of 2008 continues to reverberate loudly nationwide—destroying jobs, bankrupting businesses, and displacing homeowners. But already, it has damaged some places much more severely than others. On the other side of the crisis, America’s economic landscape will look very different than it does today. What fate will the coming years hold for New York, Charlotte, Detroit, Las Vegas? Will the suburbs be ineffably changed? Which cities and regions can come back strong? And which will never come back at all?
