I liked the gizmos that were in translucent bottles under the hood. When the engine was running it sucked hookah style and bubbled the ion-rich pink mixture in the bottle before it entered the positive crankcase vacuum hose.
The cap bank power supply on my variable frequency amplifier utilized 33,000 FARAD's of 280 volt capacitors. You read it right. Thirty three thousand farads, not microfarads. Occupied three skid pallets. It took four days to charge those caps, and when I did it, Southern California Edison grinned. Who could resist such adult auction toys? The joules total approached the potential of a lightning strike. Apparently the Spirit project utilized it at one time or another for a radar power supply. Three phase 480 200 amperes. The power cost got so bad I purchased a CAT/KATO genset to power up the caps. A bit too fast, and whoops, there goes the neighborhood, and me.
And all of it was liquidated for salvage/scrap when I got sick.
My winning purchase bid? One Thousand Ninety Dollars. Excess Endeavor Discovery refit wire? Fifty cents per pound. Teflon, silver, gold plated. I purchased about four and a half tons of it, up to 350/MCM Teflon, gold plated.
Geez, those were the days.
