Mike,

If you wrote this as a parody you were successful. ha ha. If you wrote with any seriousness, you need to find another profession. I looked at it quickly and can only say that essentially every single claim that you have put down is false. It would take me half an hour just to explain what is wrong in the any one section. Just trying to provide some accurate feedback from a scientific perspective.

Frank, sorry this rebuttal is so long. I felt it necessary to completely answered all of your objections, and, in conclusion, with all of your arguments refuted, you must agree with me. : - )

Thanks, I appreciate your support.

If you want to get smart with the wordplay, then you would be better off spending your time contemplating what responses you will give to the examiner. Smart-alec answers won't wash with the USPTO. You need to know how you will address the matters I've mentioned above;

i) the claims are unspecific and replete with terms that do not specify, with required clarity, the claimed subject matter, ii) the invention is not enabled, iii) undue experimentation will be required, iv) there is no credible assertion that the invention will perform the claimed utility.

plus I am sure you will get examiners comments that match what I posted for you to consider, wrt the prior art.

I will elaborate briefly on just one section of your proposal with my comments in CAPS:

a.) positioning the fuel at the focus of a spherical laser cavity so that--WILL IT LEVITATE SINCE ALL MATERIALS WILL VAPORIZE AT THESE TEMPERATURES.
i.) the fuel will not be able to effectively cool by radiating away light--WILL IT NOT RADIATE PROPORTIONAL TO T^4?
ii.) the reactors structural components are well shielded from the explosion,
making larger yields and higher gains possible--WHAT IS THE SHIELD MATERIAL THAT CAN DO THIS AND HOW IS IT SUPPORTED? HOW DOES YOUR "PUMP" ENERGY GET IN IF THERE IS A SHIELD THERE?
b.) making the cavity laser-active, by pumping it with enough light to cause
an upper-state population inversion--WHAT IS THE LASING MEDIUM AND WHAT IS THE EXCITATION MECHANISM?
c.) squeezing the fuel, so that
i.) the fuel becomes hot and radiates brightly (sonoluminescence) ARE YOU GOING TO DETONATE AN ATOMIC BOMB TO ACHIEVE THIS COMPRESSION? AND THIS IS NOT SONOLUMINESCENCE.
ii.) the fuel’s radiation creates an outgoing laser cascade HOW DO NEUTRONS STIMULATE ELECTRONS FOR LASING ACTION?
iii.) the fuel is in a state of pre-compression when the cascade returns--WHAT IS PRE-COMPRESSION, IS THAT LIKE UNCOMPRESSED?
iv.) the fuel is further heated and compressed by the powerful laser effect EVEN IF THE OUTGOING ENERGY WERE LASER PUMP ENERGY, WHICH IT IS NOT, IT STILL WOULD NOT MEET THE CONDITIONS FOR LASING


I will spare you and the group with any further elaboration but I hope you are getting the point.

Ignition is a term that applies in situations where the energy gain (from fusion) exceeds the energy losses (from all cooling channels). In situations where an increase in fuel temperature causes the fusion rate to increase faster than the cooling rate, positive feedback will lead to higher and higher fuel temperatures, resulting in a runaway reaction. The ideal ignition temperature is defined as the lowest temperature at which ignition can occur. If the rate of cooling can be decreased (for example, by reflecting EMR back into the fuel), then the temperature at which self-heating exceeds cooling (aka the ideal ignition temperature) will be lower, because fewer fusion reactions would be required to maintain the fuel at a given temperature.

["...provisions for pumping electromagnetic radiation..." ??? EMR of what nature?

UV, VL, IR, RF? What's the channeling method?


I think 872 nm laser diodes could pump the Nd:glass (~1055 nm) coolant. Fiber-optic cables could be used for delivery into the sphere. The quantum defect is 83%. The projected cost is less than 1 cent per Watt of peak diode power. The electrical-to-optical efficiency is over 70%, which is an order of magnitude better than NIF‘s flash lamps, and by selecting a glass with sufficiently high Nd3+-doping concentration, absorption efficiency can be near unity. Modeling shows that ~50% of the excited ions decay when the diode pump pulse is ~365 microseconds. And, compared to NIF, BSF saves an additional 10%, because it does not consume power cooling three thousand laser slabs.

Patents require precision. A counterexample: outer- and inner-planets.

I’m not impulsively driven to start construction on some half-baked plan. If my invention is destined to fail (which everyone seems to think it is), then it must have weaknesses. I want to focus on the weak spots, so an accurate assessment of its feasibility can be made. Where should I look?

Perhaps I’m missing the point, but doesn’t use of the term “acoustical medium” imply some intention to exploit acoustical properties? Yes, just about any liquid would work, but I only considered hydraulic fluid.

A bubble’s movement and position is controllable, from a distance, like a tractor beam.

Re: laser ICF + Sonofusion = BSF

Frank, : - )

a.) positioning the fuel at the focus of a spherical laser cavity so that--WILL IT LEVITATE SINCE ALL MATERIALS WILL VAPORIZE AT THESE TEMPERATURES.

Sorry, I’m confused. Levitate what? The gaseous bubble of fuel? What temperatures? The temperature inside the reactor changes with each pulse. Please elaborate.


i.) the fuel will not be able to effectively cool by radiating away light--WILL IT NOT RADIATE PROPORTIONAL TO T^4?

Yes, but its more complicated. During compression, the plasma inside the bubble gives off volumetric bremsstrahlung radiation, having a power loss of 5.34x10-23 n2 T0.5 erg s-1 cm-3. This radiation becomes thermally equilibrated in an opaque medium of which only the blackbody surface emission is observed for strongly driven bubbles, according to the Stephan-Boltzmann law, Q/A = s T4. But, it is important to realize that, because the inside of the sphere reflects electromagnetic radiation, the rate of reabsorption taking place at the surface of the bubble occurs in direct proportion to the rate of emission. The surface of the bubble obeys Kirchoff‘s Law: “emissivity equals absorptivity“ on a per wavelength basis, so that an object that does not absorb all incident light will also emit less radiation than an ideal blackbody. For a given laser intensity (W/cm2), the temperature (K) on the surface of a laser heated bubble can be calculated, using the constant s = 5.67x10-12W/cm2K4. When dealing with non-black surfaces, the deviations from the ideal blackbody behavior are determined by both the geometrical structure and the chemical composition.

ii.) the reactors structural components are well shielded from the explosion,

making larger yields and higher gains possible--WHAT IS THE SHIELD MATERIAL THAT CAN DO THIS AND HOW IS IT SUPPORTED? HOW DOES YOUR "PUMP" ENERGY GET IN IF THERE IS A SHIELD THERE?

Sorry, I should have explained, it is the coolant material itself that acts as a shield.

b.) making the cavity laser-active, by pumping it with enough light to cause

an upper-state population inversion--WHAT IS THE LASING MEDIUM AND WHAT IS THE EXCITATION MECHANISM?

The coolant is doped with a rare-earth element, like Nd, making it laser-active.

The coolant inside the sphere gets laser-pumped, using fiber-optic feed lines.

c.) squeezing the fuel, so that

i.) the fuel becomes hot and radiates brightly (sonoluminescence) ARE YOU GOING TO DETONATE AN ATOMIC BOMB TO ACHIEVE THIS COMPRESSION? AND THIS IS NOT SONOLUMINESCENCE.

High temperatures can be achieved inside of a bubble if a spherical arrangement of piezoelectric actuators outside the bubble are triggered simultaneously, causing an intense pressure wave to be constructively amplified as it travels across an incompressible fluid toward the bubble. Starting the laser cascade does not require extremely high temperatures, so atomic bombs are unnecessary. (figure 18)


 
ii.) the fuel’s radiation creates an outgoing laser cascade HOW DO NEUTRONS STIMULATE ELECTRONS FOR LASING ACTION?

Sorry, I was referring to the temperature dependent black-body electromagnetic radiation, not neutron radiation.

iii.) the fuel is in a state of pre-compression when the cascade returns--WHAT IS PRE-COMPRESSION, IS THAT LIKE UNCOMPRESSED?

No, I meant to say that the fuel is in a state of high acoustical compression when the laser cascade returns, so that the laser can increase the compression even further.

iv.) the fuel is further heated and compressed by the powerful laser effect EVEN IF THE OUTGOING ENERGY WERE LASER PUMP ENERGY, WHICH IT IS NOT, IT STILL WOULD NOT MEET THE CONDITIONS FOR LASING

You are mistaken, the laser energy comes from the diode-laser pumps. This energy is fed in through fiber-optic cables and disperses inside the sphere prior, causing an Nd dopant population inversion. The liquid laser medium has properties that satisfy conditions for amplification of black-body emissions.


I will spare you and the group with any further elaboration but I hope you are getting the point.




Frank Sanns


 

The patent you mentioned, titled “Tabletop nuclear fusion generator,” is a non-functional tinker-toy, incapable of generating efficient power or high neutron flux. I agree with the USPTO’s decision, that the invention is not “useful.” It cannot produce efficient nuclear fusion. It is nothing like my thermonuclear power plant. Thermonuclear reactors have to be big so that the fuel can be maintained at sufficiently high densities, temperatures, and under a long enough confinement time to burn significant amounts of fuel with energy gain. They should also have shielding, more than a meter thick, to contain dangerous neutrons.

Without even beginning to address the physical aspects, the point I'd say is terribly weak is the maths.

Unless you can represent it in a mathematical form, then you have no hope of progressing the idea. *This* is what you should AND CAN look at - you only need a bit of paper.

The thing is - as far as I can tell you're claiming pumping liquid glass with lasers to induce fusion in gaseous bubbles within it. OK, sounds like a plan. Now tell us the specifics - how much power will these lasers need to generate to accomplish this, what temperature will this lead to in the glass versus the bubbles of fuel, how much heat are you hoping to reflect, how efficient will it be (losing 30% efficiency in the shells at 10kW is 3kW, can you shells be made to handle that power) etc., etc..

These types of questions are what makes your patent application 'indefinite'.

What you have is an idea whose scope [let alone mechanisms] have yet to be defined in enough detail to determine any quantities you might need to create this device. Maybe it does work, but maybe it needs to be 800,000 miles in diameter for it to work.

Here's an example; I have an idea where you feed hydrogen into an evacuated space, and the force of gravity alone will pull it all together so close that fusion will happen.

It's a great idea!!! But we *know* that needs to be 800,000 miles in diameter!!! So unless you can turn your idea into a bunch of equations then it is impossible to deduce the bondary parameters of what you need to do. And if you can't find enough information on it, then maybe it's because *you* need to try pumping liquid glass with lasers first to see what happens.

Do the lasers need to be 10W lasers and 1us pulses, or do they need to be 10 petawatt lasers with 10 femtosecond pulses? Who the heck knows?

So what you have to ask yourself is; this is a blank piece of paper in front of me and I have access to the most powerful personal computers in history, so powerful they could blow my mind clean off. Do I think I'm lucky enough to solve fusion power for humanity? Well, do ya'!?

>I’m not impulsively driven to start construction on some half-baked plan.

There, you said it yourself: "half-baked."

This thread will be closed since it is becoming a noisy distraction and is quite distant from our community's experience with real, small-scale, experimental fusion. Indeed the hodge-podge of half-baked ideas in evidence could be critiqued from a myriad of different directions, but most fundamentally for the purposes of forum discussion viability, this is stuff that stands a zero-point-zero percent chance of theoretical or practical development in its current state. The discussion so far tells us pretty much all we need to know about the discussion to come: sarcasm, chest-thumping, bickering about irrelevant details, and a steadfast reluctance from the inventor to reduce his idea to practice or break it down into bite-sized chunks.

When (if) the time comes that this is a "fully-baked" idea, let's have a new thread to treat the new developments. To me, fully-baked means practically approachable, supported by credible scientific precedent, and serious (as evidenced by leveraging the appropriate expertise and making tangible investments in preliminary research). That may seem like a high bar for introducing new ideas to our site, but ideas are a dime a dozen and we have to draw the line somewhere.

Thanks for your understanding.
