Combo & Nebulae
Hey Nebulae, what if we could turn a pulsar into a cosmic battery? I'd sketch the most efficient charging cycle, but I bet you'd want the exact equations before I even start.
Hey, that sounds thrilling. If you want the bare bones, the power output of a pulsar can be approximated by \(L = \frac{B^2 R^6 \Omega^4}{6c^3}\). You’d want to harvest the rotational energy, so the charging cycle would involve catching the dipole radiation with a resonant cavity and then using a superconducting loop to store the flux. The efficiency hinges on minimizing magnetic losses, so keep the coil geometry as symmetrical as possible. Let me know if you need the full derivation or a simulation plan—happy to help fine‑tune the model!
Nice, that’s the sweet spot. Let me grab a coffee and run a quick Monte‑Carlo on the coil geometry—if we hit >95 % efficiency, we’re basically owning the next solar system. Need any tweak on the magnetic profile or just the raw numbers?
Sounds like a stellar plan! Give me the raw numbers for the magnetic field strength and the coil’s dimensions, and I’ll tweak the profile to keep the field as uniform as a quiet night sky. If the Monte‑Carlo spits out a >95 % efficiency, we’ll be the pioneers of a new kind of cosmic power grid. Just let me know the details, and I’ll run the checks in my head—no need for super‑formal equations right now.
Sure thing—pick a mid‑range pulsar, say a magnetic field of about 1 × 10⁹ tesla and a rotation rate of 500 rad/s. For the coil, go with a 0.5 meter radius, 1 meter tall loop, made of YBCO at 77 K. With that geometry and a perfectly symmetrical layout, the Monte‑Carlo runs to about 96 % overall efficiency, so we’re in the green zone. Let me know if you need a tweak on the radius or thickness.
That’s a pretty solid set‑up—1 × 10⁹ tesla, 500 rad/s, a half‑meter radius coil, and YBCO at 77 K gives a nice, tidy field. If the Monte‑Carlo is giving you 96 % overall, that’s the sweet spot for a cosmic battery. Just keep an eye on the thickness to avoid any edge‑field quirks—maybe a couple of millimeters thick is enough to keep the superconducting state stable without adding too much mass. Looks like we’re ready to power a whole solar system.
