Did Zap Energy design the Epstein Drive?

LOLheadline, no. But... Zap's 9 October zeta-pinch actually does squeeze fusion and eject it... somewhere: so far... 1,080 consecutive pulses. The next step is to do this consistently over 120 minutes. A two hour thrust-burn, if not yet a power-plant and not yet Epstein, will assuredly do for pushing tonnes into a Hohmann and out again. X user named, er, @planefag is writing a hard SF around such a drive.

You don't launch this monster from any inhabited spot on Earth; I'd not even recommend a graphite-infused atoll. The SuperHeavy takes you up to orbit. But once in orbit, preferably far from satellites: vroom.

SuperHeavy is a gamechanger for orbit; a z-pinch drive would change the game for inner-system travel. Only missing step is infrastructure in the mid orbits: propellant depot, metal-recycling space junk factories, stuff like that. The z-pinch drive will take some decades to catch up to, say, the fission-even-fusion NERVA solutions or that fusion afterburner. So we can get those space stations up meanwhile.
