I have nothing against more fusion research, its just stealth companies that I find untrustworthy, if they did their research in a more open academic setting…

Though we will have some water shielding to protect the crew from neutrons, a much lighter magnetic bubble (such as M2P2) will deflect the charged particles of the solar wind. If the bubble is large enough (many miles) the solar wind can propel the craft.

Of course water is heavy! But when you have 1million ISP engines you can have a battlestar galactica ship worth in shielding with massive engine arrays and still travel to pluto and back with only 10% of you mass in fuel! Have you read the Scientific American article on spaceship shielding?
Basically a magnetic shield would be a gross hazard for the crew, would require a large cryogenic support structure and expensive superconducting magnets. A magnetic bubble would require fuel (to be plasmafied) and though it could shield against solar wind it would be useless against high powered cosmic rays.

Artificial gravity can be generated aboard a small craft by revolving the crew

Well if you find it questionable then could you at least admit to the possibility that they are just jerking it for the money?

Here how a stealth mode companies works:

Why not just use the DPFs to propel a very larger ship with water tank shielding and enough space for artificial gravity?

Lets be realistic here: a DPF is not a vonder engine, sure its has a ISP between 100,000-2,000,000sec but its does not have much thrust, this makes it great for speeding from planet to planet but a DPF could not “take off” from anything larger then an asteroid. So DPF does not answer the hardest problem there is in space travel: getting off the earth. Unless of course you use some DPF powered laser/maser array to

Preaching to the choir?

[Transmute]

There probably a scam, I don’t trust stealth mode companies.

I’ve heard of EEStor before and I’m still very skeptical of their claims, until I see it work its just a nice dream (just like F2)

[Transmute]

There are several post peak oil energy economies, for this forum I’ll focus on three:

F2 economy: Fusion providing most if not all the input energy. This is base on the unlikelihood of cheap F2 coming out as advertised and quickly.

Transition: Solar, wind, biomass, coal gasification step up as oil falls down. Coal would provide continues energy while solar and wind provide intermittent energy that would be used to charge EV or make hydrogen. Biofuels and coal gasification supplement dwindling oil in doing everything electricity and hydrogen can

Oh good I was worried you guys needed two decelerators (one in back and in front).

I don’t prefer wikipedia as a source, rather I scrolled down to the references at the bottom. It best to hear from the horses mouth, rather then from hundreds of random dingbats that tell you second hand what the horse said. (www.wikitruth.info plug here)

True with electric cars taking up most gasoline you could cut oil use in half (gasoline represents 45-55% of oil use), and thus extend existing supplies, but even if you choose to ignore the probable (we can agree its

I’m not going to argue about global warming, Darwinian evolution was highly debatable in its first few decades, heck there are still people to this day that preach a

[Transmute]

Good point, I was thinking that F2 would come online in a post peak oil environment where oil would be ridiculously expensive anyways even with an influx of alternative fuels. Global warming is not the only concern; limitations in extracted fuels supplies is the other. At present we have (probably) reach the maximum supply rate of conventional oil sources and should expected a decrease rate from now one (enhance

[Transmute]

Not to seem laconic but “if” is the problem: if it works and if its as cheap as advertised, if not well at least it makes a nice x-ray generator :p

Aside for the “if” my focus is on the energy economy. Grossly cheap electric power from focus fusion power plants (F2) will automatically out-compete just about everything else. Anyone that has enough money to make conventional power plants will already have enough to make arrays of F2s, in fact because of the scalable nature of F2 reactors (~5MW a piece, potentially small enough be shipped on a semi-truck) it might be cheaper to forgo maintenances on some types of existing power plants and phase in F2s on the spot! Grossly cheap electricity will also change the economic order of fuels: today fossil fuels are the cheapest sources of energy in most places, F2 will flip the order around with electricity the cheapest, hydrogen (from electrolysis of water) second cheapest, followed by hydrogenated depolymerization of biomass. One problem is that F2 powered coal to oil conversion would also become economical and competitive with F2 powered biomass to oil (hydrogenated depolymerization), biomass would not add any net CO2 to the atmosphere, coal as we all know does. So even though F2 would cure our energy problems via the automatic demand of economics, it would still require both a political and social conscience demand to make sure it also cures are environmental problems. I think that was Cara initial concern, Cara obviously wants a perfect pollution free world and erroneous believes solar means that: solar will not provide enough cheap energy to clean up all polluting systems, we would still suck every last drop of cheap oil and dig up coal for decades to come. F2 on the other hand could achieve that, because with F2 even garbage is economical to recycle, coal could be dropped out because of its environmental concern without worrying about its economic side-effect because the alternatives will be there and they will be cheap.

[Transmute]

Not really, for example no one on this thread has mentioned economic side effects of a renewable energy. At the very least I added details or provided different aspects to the combined answer to Cara questions and argument. It would be best if you either stated an argument against or for the thread starters position, rather then criticizing the quality of others statement, doing so makes you look like someone who did not come here to have a intellectual discussion but to start a pissing contest. just a friendly word of advice, my friend.
