They Started A Chip Company

Yep. The above gentlemen have started a computer chip company. GreenArrays. And you thought making chips was a young man's game? It is true the young guys can work harder. But old guys can work smarter. And with enough coffee, on occasion they can work just as hard.

The chip company is more than old news to many of my readers.

What is new is that they have started a blog. It will be chock full of tips and entertainment - if banging bits entertains you. GreenArrays Tech

And in that vein I too have started another blog. GreenArrays and Forth. Which will document my explorations as a beginner. A journey similar to the one I made at IEC Fusion Technology.

Microsoft Looks At Polywell

Well not Polywell directly. More like a fusor. A program started by Richard Hull at the instigation of Robert Bussard and Tom Ligon.

Here is part of a message on the subject I got forwarded to me by e-mail.

On April 28th 2011, the Microsoft Corporation held its annual Hardware Summit. This year’s theme was “Envisioning the Future”. The Summit was comprised of three primary technical offerings. The first was the Hardware Summit itself with featured presentations and keynote address. The second was a vendor showcase, and finally there was also a “Garage Science Fair”. I was unaware that a decision was made at Microsoft Headquarters early on to move our offering from the “science fair”, to the “Featured Speakers” forum. We directly followed Dr. Brian Greene the keynote speaker on the first day of the forum. Our team was offered to several hundred corporate employees, as nothing less than professional scientists.

The cool and collected demeanor of our team under extreme pressure, as well as solid execution of their operational duties left the audience drop-jawed. Many of the early arrivals began snapping pictures with their cell phones, and forwarding them to other employee’s. The result is that we concluded with standing room only. Dr. Brian Greene, noted author and physicist from Oxford University was conducting a book signing on the first floor when he heard about our team. He left his signing to personally attend the rest of our presentation. Below was the write-up on the Agenda. Next Wednesday, Channel 9 from Microsoft will be here to film us in action. And we hope to do a presentation at the Pacific Science Center sometime this summer. The reactor was reviewed in detail by fire, security and nuclear safety personnel who found us to be in compliance for the show.

You can find out more about what they do at The North West Nuclear Consortium.

The North West Nuclear Consortium is a privately held youth group currently meeting in Federal Way Washington. It was created in direct response to needs expressed by both parents and students of public and private schools in South King County. They feel that Technology and Science curriculums are no longer interesting to students, due to budgetary constraints, and changes in school policy brought about by the abuse of tort law. Mr. Greninger leads a Christian fellowship at his home, and felt this was a challenge his group could not ignore. Starting in mid-2009, Mr. Greninger begin visiting a local youth camp with a “high voltage” show, in which he demonstrated large tesla coils and Van De Graaff generators, as well as other “gee-whiz” physics.

The youth group that was spawned through these shows now meets at Mr. Greninger’s home and studies one of the most exciting high end physics curriculums in the state.

Polywell - Positive Results

Alan Boyle has the latest on Polywell.

A Navy-funded effort to harness nuclear fusion power reports that its unconventional plasma device is operating as designed and generating "positive results" more than halfway through the project.

And that is not all:

"It's a very nice machine," he said. "I like what we have so far. It's quite well-built, relatively flexible to actually explore a lot of areas and find what's best. Achieving the plasma for fusion is obviously a tall order. ... You don't just push the pedal on a Ferrari and drive the car. Like an F-18 or a stealth bomber, you have to learn how to operate it properly."

And:

Park figures that the money provided under the WB-8 contract should last until the end of the year, depending on how efficiently the EMC2 team is able to stretch the money out. By then, the engineers in New Mexico and their backers in the Navy should know whether it's worth going ahead with the next step, perhaps even with the big demonstration reactor. Park hopes that WB-8 will be the last small-scale experimental machine EMC2 will have to build.

"This machine should be able to generate 1,000 times more nuclear activity than WB-7, with about eight times more magnetic field," said Park, quoting the publicly available information about WB-8. "We'll call that a good success. That means we're on track with the scaling law."

Don't expect weekly updates about EMC2's progress. "Currently all our funding comes from the Navy," Park said. "That's our customer. Our customer desired that we keep most of our progress confidential. ... They're somewhat concerned about making too much hype without delivering an actual product."

Go read the whole thing.

Thanks to the boys at Talk Polywell for the heads up. Good discussion of the implications there.

ITER Meltdown

The International Thermonuclear Experimental Reactor (ITER) did not melt down from an excess of energy production. It is melting due to budget excesses.

It has been billed as the solution to tomorrow's energy crunch, but ITER, a massive fusion experiment by seven international partners, is under serious threat from a present-day problem: the financial crisis.

In a meeting on 26 May, the cash-strapped member states of the European Union (EU) were unable to agree on how to find the additional billions needed to finance construction of the giant reactor, which is sited near St-Paul-les-Durance, France. The EU is set to contribute 45% of the construction costs for ITER, which some estimates now put at €15 billion (US$19 billion) -- three times the 2006 cost estimate (see 'The ITER rollercoaster').

Left unresolved, the impasse in Europe will, at best, delay the project further. At worst, it could cause ITER to unravel entirely.

All the while Polywell Fusion and other small fusion programs are getting along on budgets 1/100th the size and are actually making progress towards answers.

Polywell - No BS - No Excuses

Alan Boyle's Cosmic Log has a new article up on Polywell Fusion.

You won't hear Rick Nebel talking about fusion as a challenge requiring billions of dollars and decades of experimentation. For the past couple of years, Nebel heads up a handful of researchers following the less-traveled path to fusion at EMC2 Fusion Development Corp. in Santa Fe, N.M. That path involves creating a high-voltage chamber to sling ions so energetically at each other that at least some of them fuse and release energy.

EMC2 recently created a buzz in the fusion underground by reporting on its Web site that a series of experiments was able to "validate and extend" earlier results reported by the late physicist Robert Bussard. The company is now using a $7.9 million contract from the U.S. Navy to build a bigger test machine, known as WB-8. (WB stands for "Wiffle Ball," which refers to the shape of the machine's magnetic fields.)

What's more, Nebel and his colleagues are now seeking contributions to fund the development of what they say would be a 100-megawatt fusion plant - a "Phase 3" effort projected to cost $200 million and take four years.

"Successful Phase 3 marks the end of fossil fuels," the Web site proclaims.

Success isn't assured. The WB-8 experiment could conceivably show that the approach pioneered by Bussard, known as inertial electrostatic confinement fusion or IEC fusion, can't be scaled up to produce more power than it consumes. And if Nebel's team comes to that conclusion, he doesn't plan to pull any punches.

"No B.S. and no excuses," Nebel told me over the weekend. "If it looks like we have a problem with this, we're going to tell them."

Now that is a really different attitude from what has gone on in ITER. It was obvious to me a few years ago that the program was in trouble. But only in the last year have they admitted it by slipping the schedule by almost three years. So far.

You can read my earlier post on what I learned from EMC2 at WB-D which has some nice pictures of experiments and their proposed 100 MW device.

From time to time there are people reading here who need to be brought up to speed on fusion I'm reposting my usual: You can learn the basics of fusion energy by reading Principles of Fusion Energy: An Introduction to Fusion Energy for Students of Science and Engineering

I'm a big fan of small fusion projects. Especially after hearing what Plasma Physicist and author of Principles of Plasma PhysicsDr. Nicholas Krall said, "We spent $15 billion dollars studying tokamaks and what we learned about them is that they are no damn good." And they seem really hard to build even. And who knows, if the Polywell experiments being done by the US Navy are successful the ITER project may just wind up as a big hole in the ground in France.

Atmospheric Fusion Reactions

My friend chrismb at Talk Polywell alerted me to this Russian paper on atmospheric fusion reactions caused by Deuterium - Deuterium (heavy hydrogen) reactions in lightning.

To produce thermonuclear reaction it is necessary, firstly, to have nuclei with a large quantity of neutrons available, for example, deuterium nuclei, and secondly, these nuclei should possess sufficiently high velocity and merge together upon collision, having overcome the Coulomb barrier. It turns out that all these conditions are observed in the course of a stroke of lightning - such a conslusion is evident from calculations by B.M. Kuzhevsky, Ph.D. (Physics&Mathematics), head of the neutron research laboratory, Skobeltsin Scientific Research Institute of Nuclear Physics (Moscow State University).

Deuterium is always present in water: on average, a molecule of DHO (water, where one of hydrogen atoms is replaced by deuterium) falls to 6,800 molecules of H2O. That means - taking into account the quantity of water vapour available in the atmosphere (i.e. 5õ10^-4 g/cubic centimeter) - there will be 10^15 deuterium atoms per cubic centimeter. In lightning, these atoms turn into ions and are capable of gathering speed up to considerable energy. With the lightning canal diameter varying from 2 millimeters to 5 centimeters, and discharge duration making the ten-thousandth of a second, it proves that billions of deuterium atoms will have time to start reacting with each other and to generate precisely two times less atoms of helium-3 and neutrons. These neutrons already possess enormous energy - 2.45 MeV. However, in the atmosphere of our planet they are capable of living at most for 0.2 seconds, during which they will inevitably meet with nitrogen atoms and be absorbed by them. This time period is sufficient for neutrons to fly a distance of one or two kilometers.

The calculation has been also confirmed by experimental data. The DYAIZA facility developed at the Institute and installed in Moscow at the Vorobyevy Hills repeatedly recorded neutron emission peaks during thunderstorms, their magnitude exceeding that of the background by hundreds of times.

Several important conclusions can be drawn from the above effort. Firstly, this helps to solve a long-standing puzzle: why cosmonauts on board the MIR space station observed high neutron background in the area of the equator. Keeping in mind that thunderstorms permanently burst out in this region, it is easy to guess where high neutron background comes from. Secondly, the same mechanism should also work in the atmospheres of Venus and Jupiter where thunderstorms are also frequent and sporadic neutron streams should arise there.

In effect the atmosphere has been running its own fusor experiments for billions of years.

Venture Capital Likes Fusion

If you read my post Investing In Polywell you would know that venture capital seems interested in funding fusion start-ups. We now have more confirmation in this Finance Business article.

A prominent venture capitalist, Wal van Lierop, of Chrysalix Energy Venture Capital, has begun to invest in companies (such as General Fusion) who are providing patents and technologies for economical fusion power. in a recent interview at the Clean Tech Investor Summit (which we're very sad we're not attending), van Lierop said that he expects large energy companies to start thinking about building fusion plants within the next five years.

As we've noted before here at EcoGeek, the best way to track down that technologies are going to (very shortly) change the world is to watch what the venture capitalists are doing. these are people who basically make ridiculous sums of cash by predicting the future...and investing in it. and since they've got so much riding on their bets, they like to do a lot of research.

Often this is research that people like me (because I don't have billions of dollars to invest) can't do. So I follow the VCs, and pay attention to what they're saying.

And what van Lierop is saying seems almost crazy, on the surface. But dig a little deeper, and things start looking exciting. despite sounding like a comic book hero, General Fusion's technology is very realistic. in a world where we're all used to hearing that "Fusion power has been twenty years away for twenty years" hearing that it's five years away is pretty remarkable.

Yes. It does seem remarkable. Except if you have been reading articles of mine like: We Will Know In Two Years or less. Or one of my more recent ones like: Advanced and Delayed.

Let me also say that I have been approached several times over the last few years to personally develop a project that would reach the fusion goal faster than any government project. One of these days I will connect either with my own project or as an assistant to some one else's project.

New IEC Fusion Research Group Opens

Space Ports reports the opening of an IEC Fusion Research facility to develop fusion for spacecraft propulsion.

AVRC has been awarded a contract by Wise County's Industrial Development Authority to manage a $7 million energy research center now under construction in the Lonesome Pine Business and Technology Park [PDF] in Wise, VA focused on the development of inertial electrostatic confinement aneutronic fusion energy at the Appalachia America Energy Research Center along with other projects in a significant energy technology portfilio.

Plans are in the works to conduct a multimillion-dollar research project in Wise to develop fusion technology into a cheap source for everything from electricity to spacecraft propulsion. Invented by the University of Illinois at Urbana-Champaign's Dr. George Miley, the process involves pumping aerosol boron plasma into a spherical container where it is made very, very hot. The atoms begin to fuse, creating energy.

The project will start small, with about 6-8 researchers, and could employ 20-28 researchers within 18 months.

That is interesting.

Whose work is this based on? George Miley who I mentioned in A New Theory Of Electrodynamics. A look at the AVR page on fusion has some more hints.

The Intertial Electrostatice Confinement (IEC) Fusion Propulsion technology being promoted by AVRC was developed by Dr. George Miley.

Fusion reactions release an enormous amount of energy which is why there is such a large push for research in harnessing the energy for propulsion systems. A fusion propulsion system could have a specific impulse about 300 times greater than a conventional chemical rocket engine. Fusion-powered rockets would use hydrogen as a propellant, which means it would be able to replenish itself as it travels through space.

I wonder how they plan to fuse hydrogen which is very difficult to fuse because it requires converting a proton into a neutron to make the reaction work. Or maybe they just plan to use hydrogen gathered in space as reaction mass and plan to fuse something else. Sort of like a modified Bussard Ramjet.


AVR has a slide show in pdf of their design. It is a variant of a Farnsworth Fusor operating with 600 to 800 volt drive which will burn Hydrogen and Boron 11. I wonder how they plan to make it work with such low drive voltages? Perhaps their plan to begin with a Deuterium-Helium 3 fuel has something to do with it.

This paper [pdf} indicates that they are planning to use the IEC design as just a thruster to start with.

A novel plasma jet thruster, based on Inertial Electrostatic Confinement (IEC) technology, is proposed for ultra maneuverable - space thruster for satellite and small probe thrust operations. The IEC Jet design potential offers an unique capability to cover a wide range of powers (few Watts to Kilowatts) with good efficiency while providing a plasma jet that can start with a large diameter but be narrowed directionally to focus on targets The IEC thruster uses a spherical configuration, wherein ions are generated and accelerated towards the center of a spherical vacuum chamber A virtual cathode forms in the high-density central core region, combined with a locally distorted cathode grid potential field, extracts accelerated ions into an intense quasi-neutral ion jet. Thus, the IEC thruster is roughly analogous to a planar electrostatic ion thruster "folded" into spherical form. Estimates suggest that its electrical efficiency would match conventional plasma thrusters, while offering advantages in design simplicity, reduced erosion giving long life time, reduced propellant leakage losses, and high power-to-weight ratio. Heat rejection is eased due to large heated surface areas making the unit especially well suited to high power operation.

That might work. And if it does fusion could come later.

Kind of like the progression in piston pump technology. First you build pumps. Very handy. Then you apply steam and pumps become a power source. Then you figure out how to burn the fuel inside the cylinder and you get an internal combustion engine. Let's hope we can compress the development cycle from hundreds of years to a couple of decades.

The Current State Of Fusion

Alan Boyle at Cosmic Log has the latest broad look at the state of Fusion. He discusses the state of laser fusion. The the $3.5 billion American National Ignition Facility seems to be doing well. But what excites me is that he has some indirect news on The Polywell Fusion Reactor experiments.

The dark horse in the fusion race is an approach known as inertial electrostatic confinement fusion, or Polywell fusion. This method, pioneered by the late physicist Robert Bussard, involves designing a high-voltage cage in such a way that atomic nuclei slam into each other at high speeds, sparking fusion.

That is the hope. Now what about some news?

In September, EMC2 Fusion was awarded a Navy contract, backed by $7.9 million in stimulus funds, to develop a scaled-up version of a Polywell fusion reactor. Development and testing of the device is expected to take two years, and there's an option to spend another $4.4 million on experiments with hydrogen-boron fuel (known as pB11).

In the past, EMC2 Fusion's Richard Nebel has been able to describe the team's progress in general terms, saying that he was "very pleased" with the performance of an earlier test device. But now, with more Navy money on the line, Nebel has been constrained from saying anything about the project. The fact that the research is continuing, however, appears to indicate that the results have been promising enough to keep the Navy interested.

My sources on the project have dried up as well. No one is talking. I am running on unsupported rumors and conjecture. Some think that the silence is a cover up for failure. Being a fanboy I'm more inclined that they are so wildly successful that the Navy doesn't want to let the cat out of the bag any sooner than they can help. Reality is probably some where in the middle or worse. The design is so simple that if the Navy gets it to work no country is more than 5 years behind in producing a working model from scratch (given a crash program).

As you know I have been closely following the progress of the WB-X contracts at EMC2. If you want to get deeper into them:

The DOD Looks At Energy Security

The gentlemen and gentlewomen at Talk Polywell have come across a couple of major finds. The first is a discussion of American energy security and its military implications. Energy & National Security: An Exploration of Threats, Solutions, and Alternative Futures [pdf].

Abstract – Findings of multiple Department of Defense (DoD) studies and other sources indicate that the United States faces a cluster of significant security threats caused by how the country obtains, distributes, and uses energy. This paper explores the nature and magnitude of the security threats as related to energy—some potential solutions, which include technical, political, and programmatic options; and some alternative futures the nation may face depending upon various choices of actions and assumptions. Specific emerging options addressed include Polywell fusion, renewable fuel from waste and algae cultivation, all-electric vehicle fleets, highly-efficient heat engines, and special military energy considerations.

Interesting (to say the least) that Polywell gets a mention in the very beginning of the paper. We have come a long way since the Polywell program was nearly permanently shut down in 2006.

The second paper is about funding for various quick reaction [pdf] programs by the DOD. The interesting bits are on page 11 of the document. Look at just how small the effort was in fiscal year 2008.

EMC2/IEF
Boron Fusion The objective of this project is to continue research towards a proven, validated, and reviewed and approved final design basis for engineering development and construction of full-scale clean nuclear power plants. Boron/hydrogen reactions are radiation-free and non-hazardous and well-suited to direct electric power applications to Navy propulsion, as well as to modest scale ground power plants/systems, able to be run without fossil fuels. Such power plants would revolutionize DoD power systems applications and requirements.

FY 2008 Accomplishments:
This project continued research towards a proven, validated, and reviewed and approved final design basis for engineering development and construction of full-scale clean nuclear power plants. Payoff would be elimination of the need for fossil fueled plants.

WB-8 Contract Progress

The US Navy has just published a Justification and Award for EMC2's Polywell Fusion Reactor experiment.

The highlights:

* The award is for $10 million
* WB-8.0 report to be delivered 30 March 2010
* WB-8.1 report to be delivered 30 March 2012

The WB-8.1 effort is contingent on success with WB-8.0 experiments.

What does all this mean? It is possible that there has been much more progress than was expected. You can read about the expected progress at: We Will Know In Two Years. That was published in May of 2009. The minimum time expected for results when that was published was 18 months which would have been November of 2010. Actual time from the prediction to the end of the WB-8.0 contract is 10 months. Of course this is speculative. It may be that we won't know until March of 2012. Which would make the actual time line almost three years and not two.

Polywell Gets The Dough

EMC2 has gotten almost eight million dollars to do further experimentation on the Polywell Fusion concept.

Energy Matter Conversion Corp., (EMC2)*, Santa Fe, N.M., is being awarded a $7,855,504 cost-plus-fixed-fee contract for research, analysis, development, and testing in support of the Plan Plasma Fusion (Polywell) Project. Efforts under this Recovery Act award will validate the basic physics of the plasma fusion (polywell) concept, as well as provide the Navy with data for potential applications of polywell fusion. Work will be performed in Santa Fe, N.M., and is expected to be completed in April 2011. Contract funds will not expire at the end of the current fiscal year. This contract was not competitively procured pursuant to FAR 6.302-1. The Naval Air Warfare Center Weapons Division, China Lake, Calif., is the contracting activity (N68936-09-C-0125).

I think this is the award based on the solicitation discussed here and here and here.

Evidently the $2 million promised in May was just a place holder and the actual funds are significantly greater. This means that the work on WB-8 and the engineering for WB-9 will go forward with the next milestone in April of 2011. Which is in accord with Rick Nebel's promise that We Will Know In Two Years.

A Word For The Sceptics

I was looking at the comments to my American Thinker article Fusion Energy and came across an interesting sequence of comments I had missed earlier. The first comment is by a sceptic. There are earlier comments by him in the comment section.

Posted by: WR Jonas Jun 19, 01:18 PM

I have spoken out here about my skepticism based on a provable dynamic and truth. There will always be ample reasons to spend other peoples money. To give this research or any other some noble purpose or cause does not necessarily make the aims correct or worthwhile.

If we were still shooting rockets at the moon and coming up empty or failed we would have stopped it a long time ago. This canard of ,try until we run of money, is the basis for continuing a proven failure. Because it is Navy project doesn't give it any greater chance of success.

So , how about we put the fusion research industry on a time, results or dollar limit to see if it is ever going to produce anything. Any takers?

I added the emphasis. And then there is a reply to the question by Rick Nebel:

Mr. Jonas:

I'll take you up on that.

It seems Rick is confident of getting a yes/no answer on time and within budget for the question "Is it worthwhile to scale up the Polywell Fusion Concept to the size of a modest (~100 Megawatts) net power reactor?

And what is Rick's time frame? The answer Rick gives is "We Will Know In Two Years."

ITER Fusion - 100 Years Away

The BBC reports that tokamak fusion may be 100 years off.

The Iter project was set up three years ago to build an experimental nuclear fusion reactor in the south of France.

But construction costs alone have more than doubled and some scientists now argue that the development of fusion as a commercial power source is still at least 100 years away.

The ITER guys have a well paid flack you can watch at the BBC link extolling the virtues of ITER. He calls it the world's biggest science experiment.

Compare that to the applied research on the Polywell WB-8 Fusion Reactor test which is now gearing up. And with the experiments already completed and contemplated We Will Know In Two Years if the design can produce limitless fusion energy. Or if it is just another interesting science experiment. And the answer won't cost $20 billion either.

The Boys At Talk-Polywell Have Struck Paydirt

The boys at Talk Polywell have uncovered the details of the WB-8 contract [pdf]. Those details can give us some insight into how WB-7 has gone. From the looks of things - rather well.

The current effort will build on what has been completed under these previous contracts as well as requirements to provide the Navy with data for potential applications of AGEE with a delivered item, wiffleball 8 (WB8) and options for a modified wiffleball 8 (WB8.1) and modified ion gun. The objective of this procurement is validation of the basic physics of the AGEE concept as well as requirements to provide the Navy with data for potential applications of AGEE. It builds upon previous concept-demonstration bench top versions of plasma wiffleballs. As such, it comes under the FAR 35.001 definition of applied research. The contract will be for a wiffleball 8 with 2 options for modifications to the wiffleball based upon it’s success.

OK. They are going into deeper validation. Which means WB-7 went OK.

3.1.1 The Contractor shall construct and test a small-scale MG Insulated, Wiffleball Polyhedral Device, WB8. WB8 shall be built based on results of WB7 (built under contract N68936-03-C-0031) and shall utilize design and performance knowledge gained from test of prior WB machines.

3.1.2 The design shall use circular coils around each main face cusp axis. The device shall use emitter electron gun arrays and an ion beam drive. The machine will be operated in magnetic fields with pulsed currents. WB8 shall be operated at a magnetic field strength of approximately 0.8 Tesla, which represents an increase of 8 times the magnetic field strength of previous WB machines. Improvements over previous WB machines in WB confinement, ion energy and fusion reactivity are expected as a result of these changes to WB machine design.

3.1.3 Within 20 days of completion of testing of the WB8, the contractor shall deliver a report detailing the results of the experimental testing of this MG Insulated, Wiffleball Polyhedral Device, WB8. The report shall provide sufficient information to guide programmatic and design decisions about further, refined design efforts for similar devices. The report shall address the plasma dynamics of WB devices, and shall address the scaling laws that apply to polywell fusion. (A001)

Circular coils means that there will be no significant change in geometry. That is good. Apples to apples comparisons. An increase of field strength by a factor of 8 means - if the scaling laws hold a factor of about 4,000 increase in power out. If WB-7 was similar to WB-6 it means an increase from 3 neutrons a shot to 12,000. A real countable number i.e the error bars will be much lower. A count of 3 can actually be considered a count of 3 +/-2. That is a big error bar. For 12,000 the error bar is on the order of +/-100 about 1%. That makes improvements or degradations of 5% easily detectable. Where as in the first situation (WB-6/7) changes that doubled or halved the output rate would be hard to detect.

3.1.4 Within 30 days of build and test of WB8, the contractor shall provide a predictive model of WB behavior including data points for detailed 2D/3D profile measurements of plasma density, ion energy and WB magnetic field structure during follow-on tests to validate the scientific basis for a Polywell fusion power reactor, and guide further research. The contractor shall coordinate with the Government for a program review meeting at the contractor’s facilities to be held no later than 40 days after the testing of the WB8 and shall provide the detailed predictive model and data points at this program review meeting.

3.1.5 The contractor shall deliver a periodic progress report specifying status information of the experimental testing of the MG Insulated, Wiffleball Polyhedral Device, WB8. (A002)

The magnetic profile of an operating device is critical for knowing how the device actually operates. Without that it is very difficult if not impossible to design in improvements.

3.1.6 The contractor shall deliver a conceptual design for a follow-on fusion demonstration device, WB-9. Conceptual studies will focus on the feasibility of extending the WB-8 results to this device and determining the suitability of this concept as a fusion reactor. This design will be delivered at the end of the contract.

So the program is starting to take on a life of its own. A WB-9 device is already under consideration even before experiments on WB-8 are even completed. This indicates a fair amount of confidence in the forthcoming results. Excellent.

Now here comes what I consider the most critical requirement of WB-8testing.

3.2.1 Enhanced Ion Drive with PB11 (proton/boron 11): Based on the results of WB8 testing, and the availability of government funds the contractor shall develop a WB machine (WB8.1) which incorporates the knowledge and improvements gained in WB8. It is expected that higher ion drive capabilities will be added, and that a “PB11” reaction will be demonstrated. The contractor shall investigate and validate the plasma scaling laws with respect to B-field, voltage and reactor size. The contractor shall investigate the feasibility of a neutron-free fusion power reaction using a polywell WB machine. It is anticipated that improvements in WB confinement, ion energy, and fusion reactivity will be demonstrated in WB8.1. Improvements over the WB8 predictive, computational model are expected, which should yield a better understanding of the WB fusion reaction thus allowing optimization of the WB machine.

3.2.2 The contractor shall deliver a report detailing the results of the experimental testing of WB8.1. The report shall provide sufficient information to guide programmatic and design decisions about further, refined design efforts for similar devices. The report shall address the plasma dynamics of WB devices, and shall address the scaling laws that apply to polywell fusion, and the feasibility of the PB11 reaction. The report shall address the conceptual requirements for a polywell fusion reactor capable of generating approximately 100mW. (A0001)

3.2.3 Within 30 days of testing, the contractor shall update the predictive computer model of WB behavior created under paragraph 3.1.4 using the PB11 reaction and shall deliver the model within 30 days of completion of initial tests specified in paragraph 3.2.1.

The fact that they are contemplating work on the pB11 reaction is very encouraging. That fuel is one of the most difficult to burn in a fusion reactor. Which means testing with lesser fuels (or simulated fuels) has gone very well indeed.

At 100 milliwatts for a follow on reactor they are starting to get into the power range. If they can get that kind of power with .3 m dia. coils and .8 T fields, then a reactor with 3 m coils and 10 T fields should produce about 2.5 Mega Watts if the scaling laws hold.

And just as a little kicker:

3.3.1 The contractor shall develop an enhanced ion drive system that is compatible with Wiffleball 8.1 and projected future wiffleballs. The ion drive system shall be capable of injecting protons (ionized Hydrogen), and ionized Boron 11. The ion drive system shall be capable of generating ions in sufficient quantity to fully fuel the wiffleball fusion machines.

If they are going to fuel even a small machine the ion guns are going to have to be capable of multi amp currents - each.

Well that is my first cut at digesting the news. If you want to figure out more a look at all the links at Talk Polywell will be helpful. I especially liked this inventory [pdf] of items purchased since about 1999.

All in all the new contract has a lot of good news. To sum up:

What it means about past work: it went well.
What it means for the future: verifying engineering rules
More: there is a plan to test the Hydrogen/Boron 11 fuel combination
More: They must be confident of results since they are planning a WB-9

Why hasn't Polywell Fusion been fully funded by the Obama administration?

The Future Of Energy

I don't agree with all the prescriptions presented. However, his outline of the problem is good for some critical thinking. The secret word is Terawatt. But a terawatt is only a rate of delivery. To be really useful it has to be ready to go when you need it. That would be terawatt-hours. And terawatt-days. And terawatt-months. And terawatt-years. And then comes reliability. Can the production be sustained? What is the up time? Is the resource seasonal? Can it be matched to demand?

I do like his idea about upping the research budget to $10 billion a year. I know. A quick ramp up will encourage a lot of waste. The problem is that you never know where a good idea will come from. Suppose we spend that amount in inflation adjusted dollars for 20 years. That is $200 billion. Suppose we only get a significant pay off from 10%. If that 10% covers even half our energy supplies (i.e. what ever technology that is developed is cheaper than the alternatives) it will have paid for itself.

There are a lot of interesting ideas available. Pebble Bed Reactors, Molten Salt Reactors, and others.

We need to phase out subsidies for solar and wind. When they become economical they will roll out on their own.

My thoughts? Well they drift back as always to The Polywell Fusion Reactor.
