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.

Great vid as always, love this tech that is probably going to happen in some form of fashion, just wish it got hear for me to see. fingers crossed. Curious, Issac Arthur's channel got me hooked on Orbital Loops. What is your thoughts on alternatives to getting off earth? Sky hooks are another that seem pretty neat, at least for non living cargo. This was around the time I was reading SevenEves by Neal Stephenson which seem to have some solid science in it and started my curiosity for these epic mega projects that will probably only be under a global effort and think that too is also a few generations yet to come. Another idea after we get enough production in space is building a laser highway to mars and back, would change the cost considerably and I personally see the tech being spawned from how we inevitably start dealing with Kessler Syndrome. We will have to clean up the orbit, personally i think swarm tech will pay dividend's here. cheaper, and many, i know it sounds crazy but basically we need to herd this material in some way and why not go with what we know. its like dog herding... i take that back, its like rocket sled dog herding, but i dirges. Seems to me once we get manufacturing started and start spitting out cubic meters of aluminum sheets and girders and robot welders, we can start building the containers that will allow us to start stockpiling fuel, ore, people, science, tech ect. Personally I think the insect world will give us some solid ideas on form. SevenEves 'Nats' have been running around my brain for a while now, along with their evolved counter parts in part 2. Anyone have any favorite hard science fiction for off world stories? curious, could wireless power work reliable to space side robots so they can top off while out on the hull? would free up mass for more tools or sensors. centipedes would be a pretty good platform for low to no g environments. Each segment could be standardized in some way for some slick plug and play. Another big project i know i'll never see, O'Neill Cylinder. Media shows these naked to open space, but they will probably covered the processed material after getting the metals out. Now i'm curious on what ceramics can be made, can we also make aluminum foam or how about ZBLAN, that is worth a fortune and will make the internet faster so i'm in. once we start building up there radiation will be selling point and a huge focus for many industries and the novel combined solutions a generation after we've been up there will make many of concerns look kind of silly. disclaimer: when i say i'm curious i'm just adding to my endless 'to-do' list. anyway, i'm rambling. great vid again and i would giggle and dance a jig if i lived to see the day we had some serious freight and even a few luxury liners touring the solor system. who wouldn't want to live off earth for years? I've been joking but nearly serious about covid giving me no opt out mars isolation training. I crossed a few weird moments but think i'm ready for deep space.. :D have a great night everybody, this channel makes me awe and grateful and after the last 18 months I welcome the distraction.

Have a wonderful New Year's ! / instant travel is faster ! / / thanks

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

Since Starship is still in its prototype phase and we do not know its full capabilities, it does not make sense to use it (yet).

So much clean energy... I wonder why this technology doesnt receive the deserved attention from people. The progress on building a functioning and cost-effective fusion reactor is so slow, yet this tech could revolutionize our world.

Great video and animations. I have a question/thought on this proposed engine. Would it not be simpler to use deuterium-deuterium fusion, instead of using tritium-deuterium? I understand less energy is generated by deuterium only fusion, but if I'm not mistaken there would be no neutrons that are ejected from the reaction, which would avoid energy loss and damage to the engine. Additionally, tritium is enormously expensive from my understanding, deuterium, on the other hand, is considerably cheaper which could drastically reduced costs. So am I missing something hear? Why not pursue deuterium-deuterium fusion engines? Edit: But on second look, it seems that deuterium-deuterium fusion still ejects neutrons to generate helium-3, which makes my point moot, this makes me sad

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.

Is there possibility of a video using Positron Dymamics of an antimatter drive please loved the video.

I think the main drawback is the power source for the magnets all the energy going to thrust is a great way to boost efficiency but that means the heat and pressure don’t contribute to the next fusion pulse right? So I the ship would probably need to use NEP to power the magnets and that will increase the overall size but with so little damage from the fusion reaction it can probably be reusable.

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.

After watching Artemis 1 recently launch going to the moon, I'll be very excited to see fusion accelerate missions to Mars.

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.

I wonder how that will look like when they need to turn around "We gotta turn around!" "Yeah just get out and push!"

One day we will look back and see how far we were from the answer to space travel

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.

Aneutronic fusion fuels like He3 & Deuterium should do the trick

Electromagnetic fusion drives may give way to Gravitational wave fusion drives. If gravity wave manipulation is how UAP's are able to fly it seems that gravity waves could replace EM fields as a means to achieve fusion in these engines. Plasma could be contained using those gravity waves.
