    Large electric motors, batteries and vehicles

    I’m still living by the way. Just not worthy of being called a rocketeer anymore 🤷Found this story that might interest fans of kinetic energy 🤓: “The terrorists recognized me from a distance of 10 meters. In addition to their Kalashnikovs, they had a machine gun in the battle that fired bullets...

    Nuclear Thermal Rocket (NTR) Propulsion

    This is about a controlled nuclear reactor heating up a gas, much like where Homer Simpson works, except instead of being pressured against a turbine, the heated gas is expelled. For space flight, I would summarize the choice of gas as a trade-off between cost and mission duration. If you want...

    Fusion Breakthough

    When you ask the question whether $1B should be invested in a space telescope, a particle accelerator, or trying to reach another planet, fusion research fits right in as a 4th option. I'm not sure about pointing out a hurdle. I'd say it's about increasing the "energy out/energy in" ratio, and...

    Nuclear Thermal Rocket (NTR) Propulsion

    "Other propellants have also been proposed, such as ammonia, water, or LOX, but these propellants would provide reduced exhaust velocity and performance at a marginally reduced fuel cost. Yet another mark in favor of hydrogen is that at low pressures it begins to dissociate at about 1500 K, and...

    Marvin the Martian’s Martian Rover (of perseverant LEGO bricks (from Mars))

    Marvin: These parts are to build a mechanism with two axes of rotation about two small arcs. The black shafts are along one axis of rotation ... … and the red shafts are along another axis of rotation. The yellow 4-tooth gear is like the spider gear of a differential but the mechanism as a...

    ICEs and EVs

    Thanks for the warming. I'm anti-greenwashing by anyone, and against putting people at risk, which is why I like and follow progress in batteries and EVs. https://www.autoinsuranceez.com/gas-vs-electric-car-fires/ ⚡🔥⚡🔥⚡🔥⚡🔥 https://sacrilegemotors.com/

    Hydro-electric power (and other non-fossil fuel generation methods) discussion

    Adjusting spending and income to and from various subsets of the population is not malicious, it’s what governments do. It’s like a never-ending game of whac-a-mole 😆 Whether we have 100 years worth of oil left, or a 1000, I'd say we're better off using it to build renewable sources like hydro...

    Hydro-electric power (and other non-fossil fuel generation methods) discussion

    I didn’t read beyond “collapse”, because I know very well there is no collapse. And just a reminder that it’s perfectly possible to discuss energy for years and years without mentioning government and subsidies, but I didn’t bring up this thread so no argument is on me. From what I’ve seen...

    VW Fans

    In Germany, the ID. Buzz helped VW surpass Tesla in EV sales: "VW edged past Tesla in electric car registrations from January through July, thanks to added volume from its newly launched models, especially the ID. Buzz passenger van and its commercial variant, the ID. Buzz Cargo."...

    Fusion Breakthough

    They did it again: https://www.sciencealert.com/us-lab-achieves-fusion-ignition-in-repeat-of-breakthrough-experiment I'm glad no one is contaminating this thread with their grudges about gvts and subsidies and incentives and so on. I hope it stays that way.

    ICEs and EVs

    I like the idea of a base price to rent the square footage, plus a price for the energy. That would prevent people from using the spot for parking only. Unless they pay. Specific prices could depend on location. They’re a money-making business with the additional competitive advantage over gas...

    Book Review "From the Earth to Mars"

    That reminds me one I borrowed from a library some time ago. I don't remember if I ever finished it, but I think it was this one (the first edition was in 1996): https://en.wikipedia.org/wiki/The_Case_for_Mars
