02/28/2025 - 11:59 AMIdk, mining the moon feels like its gonna irrevocably screw up the tides
@Alex32bjr
02/28/2025 - 11:59 AMAn update needs to be made ! Just in the last year, reshearchers in Britain got more energy out of the process than they invested in it

02/28/2025 - 11:59 AMMagnetically Confined Hydrogen Storage for Space, Fusion, and Beyond
Hydrogen is the most abundant and energy-dense fuel in the universe, but storing it efficiently has always been a challenge. Traditional methods—cryogenic tanks and high-pressure storage—cause boil-off losses, require heavy containment structures, and reduce efficiency.
A magnetic hydrogen storage system could revolutionize space travel, fusion power, and terrestrial hydrogen energy storage by using superconducting magnetic fields to hold hydrogen without physical walls.
Advantages of Magnetic Hydrogen Storage
1. Zero Boil-Off Losses – Hydrogen is suspended in a vacuum, preventing heat transfer and eliminating waste.
2. Lightweight & Scalable – Removes the need for bulky tanks, reducing weight for spacecraft and allowing compact storage for energy grids.
3. Direct Fusion Fueling – Hydrogen can be dynamically fed into fusion reactors, either in space thrusters or land-based fusion power plants.
4. Safer Storage – Prevents high-pressure explosions and leaks common in traditional hydrogen tanks.
5. Versatile Applications – Usable for space propulsion, hydrogen fuel cells, energy grids, and even hydrogen-powered vehicles.
Different Methods of Magnetic Hydrogen Storage
1. Supercooled Magnetic Suspension (Cryogenic Hydrogen)
Concept: Liquid hydrogen is kept at supercooled temperatures but magnetically levitated to prevent contact with container walls.
Benefits: No need for insulation materials; reduces heat transfer, minimizing energy loss.
Applications:
Hydrogen fuel storage on Earth and space stations.
Long-term deep-space hydrogen storage for interstellar missions.
2. Plasma Magnetic Confinement (Fusion-Focused)
Concept: Hydrogen is stored as ionized plasma, contained within strong magnetic fields (like a miniature fusion reactor).
Benefits:
Hydrogen is already in an energized state, ready for fusion injection.
Ideal for high-power fusion thrusters in deep space propulsion.
Applications:
Direct fueling for fusion-powered starships.
Advanced magnetic-bottle energy storage for planetary fusion reactors.
3. Magnetic Metal-Hydride Storage
Concept: Hydrogen is absorbed into magnetically reactive materials, allowing it to be released and controlled through a magnetic field.
Benefits:
Stores hydrogen at room temperature, eliminating cooling needs.
Ideal for hydrogen fuel cells, vehicles, and grid storage.
Applications:
Compact storage for hydrogen-powered cars and aircraft.
Emergency energy reserves for power grids.
Land-Based Applications of Magnetic Hydrogen Storage
1. Hydrogen Fusion Power Plants
Magnetically confined hydrogen could serve as a direct fuel source for fusion reactors, enabling cleaner energy generation.
2. Hydrogen Fuel Storage for Power Grids
Magnetic hydrogen tanks could store surplus energy from solar and wind farms, releasing it when needed.
3. Hydrogen-Powered Vehicles & Transportation
Magnetized hydrogen metal-hydride tanks could replace current hydrogen fuel tanks in cars, ships, and planes, offering safer, longer-lasting fuel storage.
Space-Based Applications of Magnetic Hydrogen Storage
1. Hydrogen-Fed Fusion Propulsion for Starships
Integrating magnetic hydrogen storage directly into a fusion thruster removes mechanical pumps and increases thrust efficiency.
2. Hydrogen Depots & Refueling Stations in Orbit
Space stations could store and distribute magnetically confined hydrogen to passing ships, making deep-space travel more practical.
3. Terraforming & Planetary Colonization
Hydrogen can be used for terraforming, fueling oxygen production from water electrolysis, or creating synthetic atmospheres.
A magnetically confined hydrogen storage system is not just useful for space propulsion—it could transform fusion energy, transportation, and energy storage on Earth as well.
By developing various magnetic storage methods, we can create a multi-purpose hydrogen infrastructure for both planetary and space-based applications.

02/28/2025 - 11:59 AMI mean yes. but everything has to work concert. I was unaware how important bees are. And the fat fuzzy non intrusive are vital to crops, and they are cute to see them buzzing about your garden. They are peaceful, and dont bother people. jus doing their thing.

@bro_brawlstars2166
02/28/2025 - 11:59 AMWell now 8 years later fusion reactors are used to power AI's and LLM's and ofc they are funded by billions of dollars

02/28/2025 - 11:59 AMi always wondered what would happen to our world if energy was ‘cheap’ and clean
i used to think this was the ultimate goal and would bring peace but i feel so sad about the state of our country

02/28/2025 - 11:59 AMThat DBZ fusion got me
@EthanH46
02/28/2025 - 11:59 AMwhy do these videos never explain how fusion makes usable energy people get the process of fusion but how is that transferable to usable energy….???? nuclear is still in essence a steam engine so what is fusion and how do they transfer the fusion process into usable energy??? that would be nice thanks?

@paulperez3324
02/28/2025 - 11:59 AM0:29 Nuclear waste is not glowing green goop in the a yellow barrel its just radioactive metal. That sort of anti nuclear propaganda is why we dont use nuclear power even though its literally just a really efficent steam engine

02/28/2025 - 11:59 AMYeah, 10 billion dollar gamble is too much, but 500 billion dollar gamble sounds quite affordable
@deydraniadiancecht8298
02/28/2025 - 11:59 AMIt's a failure. It'll never ever be a source of energy.

02/28/2025 - 11:59 AMThe windmill energy process gives a lot of chemical dust wast around the windmill. Solar power has environment isues too. Water energy means a less good natural environment for all the living species, as well as proven explosion of dams risks where the total valley looses the vertile soil upperlayer and will give so much garbage with it that the sand will not easily get cleaned again. We do need better sand cleaning machines though.. Also for in the building, recycling and road industry. And we need to be as fast as possible with cleaning the world in order to eat as less plastics and PFAS and other bad stuff as possible. New politics and colaborations are needed. And what about space. Because of the Musk plans, nobody can reach the moon or other satellites. His satellite plans should get stopped, but exploding them in space is not an option, at least, I wouldn't, because I want a clean planet earth, and where there is enough gravity that something stays in earth's orbit, that means that it belongs to planet earth!

@royhi1809
02/28/2025 - 11:59 AMWhy is no one using methane as a catalyst to cool the plasma?
It in itself will transform into plans to cool the reactor.

@Joodles243
02/28/2025 - 11:59 AMI wonder how using the hydrogen in the ocean could help with the Ocean Acidification problem. I mean, ig nuclear fusion uses deuterium and tritium, but maybe later version could eventually use regular hydrogen? Idk
@gijsdewever5590
02/28/2025 - 11:59 AMit will be the solution for energy but i dont think we should mine-up the moon we know what happend to earth lets not make that happen to other celestial objects.
