Nuclear Fusion

In 1898, the U.S. government funded an expensive project to build the first successful flyer. Sam Langley was given $1.3 million (2012 dollars), with which he hired a large staff, purchased all manner of supporting equipment, and built a large four-winged flyer. In 1903, Langley's project attempted two test flights. Both failed miserably. The public wasn't surprised. Flight was "thirty years away, and always would be." Nine days later, two bicycle mechanics made the first successful powered flight. Their total expenditure, in 2012 dollars, was $25,400. Our own Kitty Hawk moment may be closer than we think.

Where our Current Power comes from
  • Oil
  • Natural Gas
  • Fission
The Future Clean Energy Power
  • Fusion
  • Solar
  • Wind
  • Water
What is Fusion?
  • Powers the Sun and Stars
  • In Fusion, two atoms of the same lightweight element, usually an isotope of hydrogen, fuse into a single atom of helium; rather than than splitting apart huge nuclei like uranium which takes place in Fission.
  • With Fusion there is no chance of a meltdown and relatively little radioactive waste. Radioactive waste is the most serious side effect of Fission
  • Gives off lot of energy, more than nuclear Fission
  • Carbon Free Clean energy, unlike oil or natural gas
  • Inexhaustible
  • 24 by 7, rain or shine
  • Fusion plants are no larger than existing fossil fuel plants
  • February 27th, 2014: GLaDOS explains nuclear fusion for NASA
Why is this important to me?
    Current Power
  • Limited Resource
  • Harmful to the environment
  • Even with solar, wind, biofuels, carbon capture, the use of oil is not going down because we are going to keep increasing how much energy we use
  • Fission creates high-level radioactive waste for hundreds of thousands of years
    • Fusion
  • Limitless - Supply of fuel can last longer than the sun - The deuterium extracted from 10 gallons of water would weigh about a tenth of an ounce and could supply enough electricity to last an average U.S. consumer for about 15 years.
  • Clean - Carbon Free
  • 24/7 - It does not matter whether the sun is out or rain clouds are overhead
  • Creates lot of Energy
  • Two very small nuclei are fused together instead of splitting large atoms like uranium or plutonium
  • Only a maximum of 100 years of Radioactive waste, rather than what fission puts out with a half-life up to 15 million years

The future of fusion energy
Why has it taken so long?
  • Building a fusion reactor is probably the most difficult problem that humanity has set out to solve so far.
  • Remember how magnets repel each other? Atomic Nuclei do much the same thing, only greater. This is the coulomb force which has to be overcome; the repulsive force between two nuclei. That has been the biggest problem to getting Fusion going.
  • Most techniques use ‘plasma’ heating to get the individual atoms to collide.
  • But recently what the Americans are doing with lasers holds great promise.
  • Now it seems everybody in the world is trying to get fusion going.
When will it be here?
  • The easy joke is that fusion energy is the power source of the future and always will be! But with all the potential good coming out of Nuclear Fusion, as opposed to Nuclear Fission, there are a lot of organizations working on it.

Here are just a few of them:
  • February 12, 2014 - Giant Laser Complex Makes Fusion Advance, Finally
  • In October 2013, "The BBC understands that during an experiment in late September, the amount of energy released through the fusion reaction exceeded the amount of energy being absorbed by the fuel - the first time this had been achieved at any fusion facility in the world". This is big news, the latest experiments agree well with predictions of energy output, which will provide a welcome boost to ignition research at NIF, as well as encouragement to advocates of fusion energy in general ... National Ignition Facility - Nuclear fusion milestone passed at US lab...
  • On March 15, 2012, the NIF's array of 192 lasers fired a pulse of energy that generated 411 trillion watts of peak power - 1,000 times more than whole of the United States uses at any one moment. The total energy created as the pulse was generated, was calculated to be 2.03 million joules, making the NIF the most powerful laser – about 100 times more powerful than any other laser in existence.
  • In the first week of July in 2012, the NIF's 192 lasers shot a pulse of 500 trillion watt (500 terawatt) onto a tiny target which holds the hydrogen fuel capsule, which must be compressed to about 100 times the density of lead.

    Nuclear Fission from Thorium:
    Conclusion
    It was my goal today to introduce you to Fusion power. I am sure once we get Fusion going we are not going to have to worry about power anymore. But I'm sure we are going to have to vote on building new plants for fusion use.

    My hope today is that you now know something about Fusion and are in favor of it.

    More funding needed - The world spends $7.5 trillion on energy, but roughly $15 billion on public sector energy-related research every year. That is about 0.2% of sales, which is a very small sum, and much of this goes on routes to energy conservation, renewables and private sector research subsidies, in the shape of tax rebates. To get an idea, British Petroleum set aside $20 billion to cover the cost of the Gulf spill.

    Now here's what happening in nuclear fusion today:
