Vote for vacuum accumulator
I support the idea of a vacuum accumulator to sustain the low pressure in the firing chamber as long as possible. The tube between the REHAB chamber and the accumulator needs to be large enough to accommodate the sudden change in pressure inside REHAB when the motor fires.
The cost not mentioned is that it will take much longer for the pump to achieve the targeted low pressure.
CSL Space Trilogy
IIRC Lewis insisted that these were not to taken as biblical parallels, but I don't buy that.
Peralandra is somewhat tedious because of the long debate that takes place, but the series is definitely worth a read.
Re: Low pressure only until ignintion, right?
Why not add a second chamber to the system to act as a vacuum accumulator? It will enable the pressure to drop more slowly after the motor ignites.
If the accumulator sits between the pump and the chamber, it will reduce the amount of hot gasses ingested by the pump while firing the motor.

Any Kevin Costner movie........
....except Dances With Wolves. He had so few speaking lines because there was nobody to talk with because most of the characters did not speak English. Robin Hood (boring, liked the Mel Brooks version MUCH more) and Message In A Bottle (stiff, unbelievable) both really bad. Fortunately I avoided seeing Waterworld.

Aren't there a couple of quick tiny glimpses of PARIS well after release?
Headset shocks
I have experienced shocks from headphones while riding a bicycle on rollers. It happens when the audio device is NOT in your pocket and static builds up from the rollers and discharges through the headphones. It is actually quite a blast right in the ear. I'm amazed it didn't fry the audio (CD) player.
Naturally I use a different music setup during our cold northern winters when I need the miles and our heating system dries the air.

Tracked JCB
Years ago (1980's) JCB used to make a tracked front end loader. It was quite quick. Had the opportunity to operate one briefly moving some snow around.
