npub1rv4738d6q3nxf24v4gmg4u7lh3udmarsttfzp7q0xttdlqk5ls3s65ft5j (npub1rv4…ft5j) Quantum-scale black hole! About 4Gt of mass is stable for the life of the universe to date, so it won't fry you with Hawking radiation just yet. About the volume of an electron. Stick a huge charge on it and you can bottle it using electromagnets then feed it just enough mass to keep the accretion disk hot. Behold: a matter annihilation reactor the size of a current PWR! And if you accidentally drop the hole it'll take *centuries* to consume the Earth. What could possibly go wrong?
