you DO have to put in energy for every fusion to take place, so the whole payload can't explode uncontrollably. You could, of course, fuse more fuel at once than intended, but I believe this isn't an easy mistake to make due to the large input energy that each atom requires to fuse. You'd need to simultaneously send more fuel into the chamber, input a dramatic amount of extra energy than in spec, and still maintain tight magnetic control over the larger mass.

The one working on this is Dr. Slough, for those interested. Been following his work for about a decade. His design, if/when it works, can also produce electrical power. Small correction for 0:34-1:01: solar panels produce power, not energy. It would take about 1.7 hours for stated 0.7 km2 of solar to produce stated 845 GJ, assuming a standard 200 W/m2 panel. Or, with average USA weather (CF=24.7%), you would need 0.00054 km2 to produce that energy within a year. Math: 845e9 J /(.7e6 m2 * 200 W/m2 * 3600 s/hr) = 1.68 hr, 845e9 J /(365 dy/yr * 24 hr/dy * 3600 s/hr * 200 W/m2 * 0.247 CF * 1e6 m2/km2)=0.000542 km2

Well, you got a lot of the theory right ... except for the fusing to become more massive part. It's the opposite actually ... When the hydrogen reactants fuse to produce a heavier element helium, the overall mass is reduced, which is where energy is supposedly going to come from during the fusion process. e = mc^2 ... resultant helium-4, is lower in mass, by about 0.7%, than the reactants that went into creating it, which is where the energy comes from.

Excellent video, this propulsion system would not be good for interstellar travel however because it consumes lithium. Whats needed for interstellar travel is a fission rocket that consumes only uranium or plutonium. A ship that travels at a constant 1g acceleration rate can get to Alpha Centauri in 3.6 ship/7.3 Earth years (and that includes turning the ship around half way and decelerating) or span the entire diameter of our galaxy in 12 ship/113,000 Earth years. The ship would achieve about .95% light speed after about 1 year. A 10 ton ship would need a mere 10 tons of continuous thrust. If you want to see a new fission rocket concept watch my video "liquid plutonium rocket" it also has info on the constant 1g acceleration method.

a kugelblitz black hole would actually be the most efficient drive system, but you basically require gamma ray mirror, which I don't think are possible, but like if you can make them then you can make a kugelblitz black hole. Also you need a stupid amount of energy, but like the sun puts out a bunch of energy and you "only" need like 10% if the suns output to make a kugelblitz black hole, and if you have a gamma ray mirror you can probably make a gamma ray laser, which you also need to convert the suns energy into gamma rays because you need to focus enough energy in a little bit bigger than the plank length, which means you need the highest energy 'light' to stand a chance. bonus if you have a gamma ray mirror is that you can reflect the energy coming off the kugelblitz black hole, rather than the brute force method of blocking the gamma rays and turning them into IR which can be reflected to create thrust, also if you have near perfect gamma ray mirrors you can theoretically maintain a very high power kugelblitz black hole as the lower the mass the higher the output, but also the shorter the lifespan.

Alpha and Gamma radiation doesn't stick around, and Alpha particles will get stopped easily by even the thinnest of barriers. and Gamma radiation while can penetrate decently thick concrete wouldn't go very far in atmosphere so its definitely possible. Open cycle Fission rockets on the other hand would definitely have long term radiation contamination problems.

We already have the technology to get to Mars in a month or two using Nuclear Thermal Rockets. During the 1960’s Project Rover, the Phoebus-2A had a power level of 4 Gigawatts of thrust with an SI of 840 seconds. Open-Cycle gas-core NTR designs could provide a specific impulse of 3000-5000 seconds. Project Orion involved creating spacecraft that use fission pulse propulsion where a manned design could get to Mars in about 7 days. If we can get around the danger of nuclear spacecraft accidents, nuclear fission rockets would open space for colonization for today’s world. I think the reason they are not used today is because of the stigma behind nuclear power dangers. Of course, fusion would always be better for obvious reasons but there are remarkable technologies today and in the past that are very underrated.

Wow you misunderstood this concept greatly. The lithium liner is not to contain the reaction, it's meant to start it in the first place by compressing the plasmoid to stupid pressures when it is suddenly imploded with the help of magnets. Think "crushing a tin can", only you crush it so hard that the droplets inside fuse and explode. Afterwards the lithium makes up most of the propellant, due to it being converted to plasma that gets channeled by the magnetic nozzle. No problem with ions getting trapped anywhere, the plasma is electrically neutral at the macro scale, same amount of positive and negative charges inside.

That's a really cool texh I wonder if once we have a ship yard build on orbit ion thrusters will win out I feel like fusion is just so unessercly needs to have perfect condition kinda reminds me of the nuclear explosion as thurst method awesome stuff can't wait for future space travel im currently 22 and I hope I get to see it

I think you’re greatly underestimating how feasible it is to colonize Mars with conventional rockets. The rocket you use as an example (Falcon Heavy) is not made for mass transportation between Earth and Mars. That job is for Starship, which is being designed to transport up to 100 people to and from Mars or the Moon at a time while also being cheaper per launch than any of SpaceX’s already cheap current rockets due to its full reusability. For comparison, SpaceX is targeting just $2 million per launch of Starship to LEO, at which point it will take around a dozen refuelling missions in LEO to fill back up to full. This gives us a very rough estimate of around $26 million in launch costs for a mission of 100 people to mars, just $260k per person, which is expensive but far from unaffordable. I have no doubt that one day fusion rockets will take humans all around the solar system, but at least for Mars it’s possible to begin colonization within just a few years with conventional rockets, compared to a few decades at the bare minimum with fusion.

Beamed power propulsion is currently possible and not only beats fusion, but also antimatter Combined with proposed magnetic reconnection electric propulsion, extremely fast trips to Mars could be made. The orbiting solar powered laser stations required could perhaps be developed in a fairly short time frame.

Some observations. You compare this fusion drive to a falcon heavy. Why ? It was never really intended for this, but starship is. Secondly, I'm not sure where you get strong enough magnets to compress the plasma enough. Our current efforts at getting fusion going are the size of factories. I think fission rockets are a much more feasible solution for now. It's something we could build now with our current technology. I do agree on the benefits of a faster transfer speed to Mars. The general hard radiation is pretty constant, but the danger of coronal mass ejections from our own sun varies a lot through the 11 year cycle. Right now we're coming out of a low (tried to see sun spots a few months ago, no luck there haha) but it'll peak in 6 years or so and go back down again. I doubt that we'll send any manned vehicle to Mars until getting close to the next minimum, so maybe 10 years from now. I suspect that Elon Musks drive partly stems from the realization that he needs everything ready by then, or he'd have to wait another 11 years or so.

Should also mention that you would only need ~10 grams of uranium 235 to release the same amount of energy, which is 10x more, but like your fuel is stupidly more dense like 10 grams of uranium takes up 0.000525 litters of volume, while 1 gram of liquid hydrogen takes up 0.01 litters or 19x the volume for the same energy, so your tanks need to be 19 times bigger and you need to keep the hydrogen at cryogenic temperatures, and you also need a pumping and liquification capabilities and many layers of tank to stop the hydrogen escaping. while your Uranium could be contained in a plastic baggy, and that would actually stop the radiation given off by U235 as it's a alpha emitter, so while yeh the fuel it's self may be more energy dense weight for weight, the actual systems involved in containing the fuel would make fission a better option, that ignores the reactor, you can make a pretty light weight fission reactor if you skimp on shielding the whole thing and only shield the direction in which you have crew and or equipment sanative to radiation, a fusion reactor not so much.

I would LOVE to see this CG idea mated up with a Full starship (Here after SS.)? Kinda like the idea that one SS would bring the drive up and put it into a parking orbit. Then they would send up a number of fuel SS to be in waiting for the Crew SS to arrive. Then the Crew SS launches, meets up with the refueling SS allowing them to return for refilling, then the Crew SS would move and dock with the Fusion drive module before lighting the candle as it were and making the trip to Mars. Once in Mars orbit the Crew SS would detach from the Drive module and use the fuel onboard and it's chem raptors to land the SS and complete their mission. Once they are done they could then launch the Crew SS and meet up with the Drive module before making the return burn back to Earth! This would be a truly epic use of the combined tech and I could easily see the SS being able to make this much more possible. Also just a note that was overlooked in your data is that while with CURRENT operating rockets you are correct you failed to take into account that the SS has a MUCH higher payload to orbit ratio then anything currently out there PLUS will be slated to cost a fraction of the operating cost that even the Falcon Heavy currently dose.

If you use He3 the reaction is easier to start and control and you have less radiation as if I remember correctly that reaction doesn't give off lots of neutrons.

I give a lot of hope in the development of the process, but I would have to say it would need to be tested thoroughly before any lives are risked in a journey like that. Engines are marvelous things when they work, but often the more complex that you make something, the more chances there are for it to malfunction at some point. Perhaps, as crazy as it sounds, when the scientists think they have it right, a small version of the ship could be sent by remote, crewed with a few A.I. bots, and plenty of sensors to monitor everything on board, and have the ship make the trip and return to orbit a few times, as proof of concept. You can simulate something, and make short runs to see operation, but only when you put them through the constant stresses of real operation will you truly know how well your design will perform. I truly hope to see the start of that before my lifetime is over, and wish our best and brightest the best of luck in this goal!🙂

The electrostatic or ion thrusters require independent power sources: Either solar cells or a modest nuclear reactor. Multiple junctions solar cells with mirrors operating at high temperatures have entered the 40% conversion range. Small reactors are possible but invoke political issues more than technological. Prepositioning equipment into Mars orbit and landing supplies with robotic orbital transfer systems - essentially a "tug" - even if it takes many months the robot doesn't care.

I think the first missions to Mars will be done with nuclear thermal (fission) rockets. Both the US and Russia are working on them, and at least the US plans to fly them on the SLS (unsure if that's as a replacement for the 2nd stage, or as an additional stage). The NTR is another great technology to allow missions to Mars to get there quicker (or with more payload, or some of both). I just hope it pans out, and that we don't get an unreasonable amount of protests about what the public thinks is effectively "the other N word" (yes, Nuclear's reputation is that bad to the layperson, despite it being one of the cleanest sources of energy we know of).
