First a quick note before getting to the topic nuclear fusion generators.
NASA.gov website has had a change that threw me for a loop and I should have expected it but I guess a slow learner.
I got my NASA Headquarters list server email that said welcome aboard and then a follow up email telling me I was not on a new list but just a name change. Then while trying to find some information on fusion engines at http://www.nasa.gov/

Subscribers to the email list for NASA News Releases may have received an email this weekend welcoming them to the list:
This is not a new list, merely a new return address. Over the weekend, NASA migrated most of its web services, including some of the agency's email lists. Users have not been subscribed to any new lists, and they will continue to receive one copy of each news release.
Despite the wording of the original announcement, members of this list cannot send messages to be distributed via this list, nor is its membership public.
To unsubscribe from the list, send a message with the word "unsubscribe" (without quotes) to hqnews-request@newsletters.

What the Heck Happened to NASA.gov?June 29, 2013
Notice anything different?
To start with, we've got a refreshed look, lightening the site's color palette. We hope this will address some of the complaints we've had about clutter and the page being hard to navigate visually. But that's just the beginning.
You've no doubt noticed that the navigation buttons are gone from the NASA Home Page. The topics are still there in the "Popular Topics" drop-down menu to the right of the main news stories. We moved them there to make more space for live events. When we solicited feedback on what people wanted from NASA.gov, the most-popular idea (among those we could actually implement) was to make live events more prominent. So here is where we'll be putting links to launches, major press conferences and speeches, planetary encounters and anything else we want to draw your attention to.
Over the past 50 years or so tens of billions of dollars have been spent on nuclear fusion research, yet just as some projects are beginning to get into their stride doubts are growing and funding is under threat; especially from the US.
After failing to achieve break-even last year, the fusion reactor being developed at the Lawrence Livermore National Laboratory's National Ignition Facility (NIF), is now under threat of having its funding cut, and congress is also reconsidering the contribution that it had promised to the international ITER fusion project in France.

You may have already viewed the video at The Objective Standard link from the Lockheed/Martin Skunk Works presentation.
I found TOS Blog informative as well and got me thinking about fusion generation in general.

Skunk Works to Deliver “Energy for Everyone”

At anther link, the lead scientist, Tom McGuire's PHD thesis was mentioned in the comments, and I have been reading. My math is not that great but our 6 year old granddaughter was finding numbers and letters in the many equations. I had put it down and the next day started again. I asked her where we left off and she told me "30", that is, page 30. Right on.
Even though I don' fully understand the math, Tom passes on a lot of historical information and tells an interesting story of his thesis work. It was a long road an in his acknowledgements he mentions, "I’d like to thank my advisor Ray Sedwick for supporting me through the years (7.5, but I’m not counting)."
If you didn't check out the file before I think you will find it an interesting read. (which I am still trying to digest)

The lead scientist Tom McGuire mentioned in the presentation did his Phd on “Inertial Electrostatic Confinement Fusion Devices” – you can read all 250+ pages of it at http://ssl.mit.edu/

If you want to fly missions to far away places in the solar system it would be helpful to have some kind of continuous thrust that could be used to provide acceleration for half the journey and continuous thrust to slow down if you want to orbit the celestial body. Such missions have been proposed and a nuclear power source would be handy.
Lack of money and opposition to launching nuclear power sources can get in the way of success. Then there is the problem that present nuclear power sources are often massive. Deciding whether to include humans adds to the mix of problems that need to be overcome. You can read about the proposed Jupiter Icy Moons Orbiter (JIMO) mission or Project Prometheus to get a feel for the politics involved.
You can get a lot of heat from nuclear fission (atomic bomb, splitting apart heavy elements) or nuclear fusion (hydrogen bomb, putting light elements together). Generally speaking, bombs don't make for good sound bites to the general public, although throwing bombs out behind a pusher shield have been suggested.
So many creative ideas that make for good science fiction but are hard to achieve in the here and now. I live over a hill fromLawrence Livermore National Laboratory that is noted for its work with powerful lasers and have some really fast computers. Their job also has to do with monitoring our nuclear stock pile and finding ways to ensure a nuclear device would work if called on to do so but no more blowing up the real thing.
Creating a nuclear fusion generator using their lasers to help in ignition at the National Ignition Facility, that then might be used to generate electrical power, makes for good sound bites. Taking a long time to have success and costing a lot of money, doesn't play well with the budget watchers. Playing your national defence card may not work either.

Funding Disappears for Nuclear Fusion Following Poor Progress
By James Burgess | Wed, 26 June 2013 21:35
After failing to achieve break-even last year, the fusion reactor being developed at the Lawrence Livermore National Laboratory's National Ignition Facility (NIF), is now under threat of having its funding cut, and congress is also reconsidering the contribution that it had promised to the international ITER fusion project in France.

==============================
The World Nuclear Association (WNA) is the international organization that promotes nuclear power and supports the many companies that comprise the global nuclear industry. Its members come from all parts of the nuclear fuel cycle, including uranium mining, uranium conversion, uranium enrichment, nuclear fuel fabrication, plant manufacture, transport, and the disposition of used nuclear fuel as well aselectricity generation itself [1].
Together, WNA members are responsible for 95% of the world's nuclear power outside of the U.S. [2] as well as the vast majority of world uranium, conversion and enrichment production.[3]
The WNA says it aims to fulfill a dual role for its members: Facilitating their interaction on technical, commercial and policy matters and promoting wider public understanding of nuclear technology. [4]
Accredited to the United Nations, the WNA is an independent, non-profit organization, funded primarily by membership subscriptions.
The WNA was founded in 2001 on the basis of the Uranium Institute, itself founded in 1975.

==============================
On a daily basis World Nuclear News provides free and accurate public information on the subject of nuclear power.
The goal of WNN is use plain English to place comprehensive coverage of nuclear power in context using background information, expert commentary and links to relevant authoritative sources. Because they are researched from original source and written in-house by experienced journalists, WNN stories may be freely reproduced under certain licence conditions.
The WNN service is supported administratively and with technical advice by the World Nuclear Association and is based within its London Secretariat. It draws on the WNA's global network of contacts in industry, academia, research institutes and intergovernmental agencies that includes key personnel in enterprises that account for virtually all of the world's uranium mining, nuclear fuel manufacture, equipment production and nuclear power generation.
