We live in interesting times.

Up to 25% improvement compared to conventional rocket engines according to the Wikipedia page. I haven’t found an actual ISP measurement for this NASA engine, though.

#6Anybody know what Specific impulse we are talking about? According to wikipedia, current values for rockets are around 300s

Is that a 25% improvement in ISP/exhaust velocity or another metric?

#8At first, I thought it was an insanely scaled ion drive and then maybe a toroidal aerospike.
Nope, no grids and there's water. Holy damn.
