Thank you for understanding and considering the idea properly. I also wonder what would happen to the pellet during the pulse.
Maybe it would be finely compressed,
maybe it would need precise location and speed control,
maybe it would need special form for pellet,
maybe it would need ionization in some way.
maybe the use of lasers to preheat it could resolve the squishing problem and that could result in a hybrid laser inertial dpf.

Still we are at the birth of a fusion energy research field and I expect lots of mixing and matching from all the fusion concepts in all the design areas when we are further down the road:
confinement, thermal management, radiation management, bremsstrahlung control, fuels, switches, capacitors …

I am not a physicist, but please don’t dismiss my idea out of hand. Take a look at it this way:
You have 2 parameters in fusion, pressure and temperature. AFAIK they are interchangeable – the more pressure you apply the less heat you need. I would think that the amount of gas used for each shot is pretty small (or otherwise the e=mc2 would blow up you building), so the heating requirements should be small. The pre-compression could be done in pellet or BOC form. The pellet outer layer serving as a container (like liquid gas canisters).
I am not sure about the circumstances of the process, but:
Heating it up could not be an issue with a lot of pulse energy going into heat and small amount of gas to heat.
On the other hand, compression might be an issue, because you fill the whole vacuum chamber with loose atoms
and you must capture enough of them during the pulse and then use the energy of the pulse to compress (the pulse should be affected [weakened] by gas pressure).
Edit:
So having the gas pre-compressed should weaken the pulse less. And BOC transition into fusion plasma could be pretty instantaneous
without letting it separate the atoms to much.

I hear you on the investment thing. There needs to be a sea change in micro-investing for us little guys. That would take a whole lot of lobbying and law changes.

Tnx. Any luck on the Profounder front?

Ok, I subscribed to the FFS membership, because I saw the cost was pretty low (I think it was much higher before). I hope this will help with funding a little.
I would donate, but i am pretty poor and need to take care of a lot of people in my extended family and soon I will have my own 3’rd kid – so I am looking more for investment opportunities, than just donations.

Just want to point out to you that without cheap energy space travel is too expensive 😉

My understanding is that they get that way by reinvesting otherwise idle capital to (hopefully) make more to invest. A lack of leadership could make it look like hoarding, which would also be dumb because it makes the hoarded money even more taxable.

The scenario you described above sure looks like it’s straight out of Obama’s playbook,imo, designed to socialize America.

Thats the question:Invest in what? The biggest ROI might not be most beneficial for society. Actually if we believe in former world bank president, usually the crappiest projects get green light.
I think the government thinks it is easier to transfer wealth in large quantities, so instead of millions of transactions a few thousand each (supporting the entrepreneurs) it likes to do a few transactions in thousands of millions (support the banks) and the banks that receive this low interest government guaranteed loans just re-loan it at much-higher rates to stupid projects that they don’t care about pocketing the difference. So it is a very lucrative middle man position. I think in this age of technology we should have the means to eliminate it, but the question is how hard it is. My computer should explode any second now….

IMHO “Skepticism and the Scientific Method” is a very important topic.
I dont have much problem with others, but just to put some arguments forward:
ZPE – you need a place to put all the quacks or they will start making up conspiracies.
Also as far as I know a lot of topics we nowadays consider science were pseudo-science once. Some people consider FF to be it.
I for myself am interested in seeing evidence, whenever it comes from.

Fusion power would inject plenty of resources into the economy to over-employ every person on the planet in creative positions.
Why cant the every politician, scientist and business man see that all the solutions lie in solving the energy problem?

It seems to me of questionable value to promote aneutronic fusion at this stage of the game, as I’m not clear what the “ask” is, what action you want people to take. I would think that what is needed far more is hard dollars invested in the research, but that isn’t going to come from the general public (and presumably is better handled by LPP than the FFS).

The public thinks that there is already a fusion research that is being worked on by ITER and NIF.
If we don’t change this preconception well have fusion in 20-50 years or maybe it will still be away by this much then…

Probably a start

I scared of 2 things:
1)War fueled by fusion power
2)Runaway pollution and garbage mountains when manufacturing costs become unimportant

The unreliability of renewable’s results in increased cost to address this issue.
Basically the most important part in energy is the cost and reliability can be factored into that (high reliability = no cost to address this issue).

I don’t see myself a multi-load tether as a solution without improving the concept because it means that the strength of the tether must be increased to accommodate more load.
Actually I even wonder: what is the advantage of using a tether? Basically the only problem it addresses is avoiding reaction mass.
I would love to compare different lifting concepts on efficiency and see their advantages:fanned lifter vs plane vs balloon vs tether.
I think probably balloon would be the most efficient method for lifting.
Of course it would work only until the edge of atmosphere where you would need either a tether or reaction mass (balloon gas?).
That could reduce tether strength requirements and allow for multi-tethering or maybe produce a totally new orbital lifting concept combined with some innovative propulsion concept (dpf?).
